3) Scope and acceptance

3.1. By purchasing, downloading, installing, activating or using the Software or the Portal, you accept these Terms.

3.2. Buyer type declaration: during purchase you may indicate whether you buy as a business/professional (B2B) or as a consumer (B2C).

3.3. B2C priority: if you buy as a consumer, the Consumer Annex (B2C) and any mandatory consumer rights apply.

4) Online contracting, confirmation and language

4.1. The purchase flow will show the price, billing period (monthly/annual), applicable taxes and payment terms.

4.2. Once the purchase is completed, we will send you a confirmation by email and/or make it available in the Portal.

4.3. These Terms may be provided in one or more languages. In case of discrepancies:

  • B2C (consumers): the version provided during checkout in the applicable language prevails (and, if more than one exists, the Spanish version when required by applicable consumer law).
  • B2B (business/professionals): the English version prevails, unless otherwise agreed in writing.

4.4. Contract archive: we may archive the purchase proof/confirmation and the version of these Terms applicable to the transaction. You may consult basic items (subscription status and payment history) in the Portal while your account is active.

4.5. Error correction: before confirming the purchase, checkout allows you to review and correct the entered data. If you detect an error after purchase, contact contact@baselinksl.com as soon as possible.

4.6. Acceptance record and contracting evidence (checkout): to prove contracting and acceptance of these Terms and, where applicable, the specific consents required (e.g. immediate supply start for B2C and acknowledgment of loss of withdrawal), we may retain minimal and proportionate evidence of the checkout process, such as the accepted Terms version, timestamp, order/invoice identifiers and the account identifier used. This processing is based on performance of the contract and/or legitimate interest in proof and fraud prevention, in accordance with applicable law and the Privacy Policy. We will retain this evidence for as long as necessary to perform the contract, comply with legal obligations and address potential claims, as described in the Privacy Policy.

5) Subscription, renewal and cancellation

5.1. The Software is sold as a monthly or annual subscription, as selected at checkout.

5.2. The subscription may renew automatically until you cancel it, unless stated otherwise at purchase.

5.3. Cancellation prevents future renewals. Except as provided in the refunds section, cancellation does not automatically entitle you to a refund of amounts already paid.

5.4. Price changes: prices published in the Portal or on the website apply to new subscriptions from the publication date. For existing subscriptions, if we change the renewal price, we will notify you at least thirty (30) calendar days before the next renewal and the new price will apply from that renewal. Consumers (B2C): if you do not accept the new price, you may terminate the contract without penalty within the notice period.

5.5. Effects of subscription end: if the subscription expires or is terminated (by cancellation effective at end of period, non-payment, or termination), the Provider may stop issuing/renewing licenses and the Software may become limited or disabled when a valid license cannot be verified (see section 11). We may apply a technical grace period to allow transition, which may vary by Plan and does not constitute an SLA. In any case, while there is a paid and active subscription period, end-of-subscription limitations will not apply before it ends, except in cases of fraud, license circumvention, or material breach.

6) Payments (Stripe), invoicing and taxes

6.1. Payments are processed via Stripe. Stripe may process payment and billing data under its own terms and policies.

6.2. The Customer is responsible for keeping billing data up to date and for maintaining a valid payment method.

6.3. Taxes (VAT or equivalents) will apply as appropriate and as shown at checkout.

6.4. Non-payment and late payment: if a charge fails or amounts are overdue, we may (at our discretion) retry charges, suspend Portal access, suspend license issuance/renewal, and/or limit Software functionality due to inability to verify a valid license.

6.5. Chargebacks and payment disputes: if you initiate a chargeback or dispute, we may temporarily suspend Portal access and/or licenses while it is resolved. If the dispute is resolved in your favor, we will apply the relevant adjustments. If it is resolved in our favor, we may claim the amounts due and, where applicable, direct and demonstrable costs charged to us by the payment processor and/or reasonable handling costs, without a punitive nature, to the extent permitted by law. If the Customer requests a refund under section 8 and simultaneously opens a dispute for the same amounts, the refund process will be suspended until the dispute is withdrawn or resolved to avoid duplication.

6.6. Fees and external costs: unless we state otherwise in writing, the Customer bears any external fee or cost associated with payment or collection, including (without limitation) bank fees, currency conversion costs, transfer charges, withholdings or taxes applied by third parties or the Customer's bank. In no case do these fees replace the Plan price or constitute a discount or refund.

7) Delivery, immediate access and Portal

7.1. "Delivery" of the Software consists of immediate access to download and/or repository, and issuance of a license key linked to the account email.

7.2. The Portal allows you to manage: billing data, payments, license list and subscription status.

7.3. You are responsible for keeping Portal credentials confidential and for any activity performed under your account.

7.4. Portal data retention: Customer data in the Portal (payment history, subscription status) may be retained while the account is active, even if the subscription expires. The Customer may request deletion of their account and Portal data at any time by contacting contact@baselinksl.com. The Provider may retain data needed to comply with legal obligations (e.g. tax/accounting) for legally required periods, even after account deletion.

8) Refund policy

8.1) B2B commercial policy (businesses and professionals): 7 days

8.1.1. If you purchase as a business or professional (B2B), you may request cancellation with refund within seven (7) calendar days after:

  • initial signup, or
  • a renewal.

8.1.2. The refund will be proportional to the unused part of the billed period, calculated from the payment date to the effective termination date.

8.1.3. We may deny the refund (in whole or in part) if there are reasonable indications of abuse or fraud, including (without limitation):

  • intensive use with intent to refund,
  • an open chargeback/payment dispute for the same invoice, unless it is withdrawn before processing the refund,
  • breach of these Terms or the Acceptable Use Policy.

8.1.4. In case of denial due to abuse/fraud, we may (at our discretion) offer a partial refund, internal credit, or no refund.

8.1.5. This policy is voluntary and does not constitute a statutory withdrawal right for businesses or professionals.

8.1.6. To request a B2B refund: email contact@baselinksl.com from the account email and include the invoice and/or license identifier.

8.2) Consumers (B2C): see Consumer Annex

The 14-day withdrawal right, where applicable, is governed by the Consumer Annex (B2C).

9) License to use (not a sale) and restrictions

9.1. We grant you a non-exclusive, non-transferable and non-sublicensable license to use the Software in accordance with the subscribed plan and these Terms.

9.2. Prohibitions (except with express written authorization or as permitted by mandatory law, including interoperability rights under Directive 2009/24/EC):

  • resell, rent, assign or sublicense the Software,
  • offer the Software as a service to third parties (timesharing/service bureau) if your plan does not allow it,
  • reverse engineer, decompile, or attempt to obtain source code,
  • remove intellectual property or license notices,
  • circumvent or manipulate license mechanisms or plan limits.

9.3. Backups and non-production environments: you may make reasonable backup copies and install the Software in development/test/contingency environments provided that (i) you do not exceed Plan limits, (ii) it is not used to provide services to third parties beyond what your Plan allows, and (iii) the license is not active on more than one server at a time (see section 10).

9.4. No Software resale; Customer services: this License does not allow reselling, distributing or commercializing the Software itself (including as a packaged product or as a license to third parties). This does not prevent the Customer from providing their own services or commercializing the agents and use cases created with the Software (e.g. customer support, sales, or assistance services), provided they comply with these Terms and applicable law.

10) Activation: only one active license on one server at a time

10.1. The license may be entered on multiple servers, but it can only be active on a single server at a time.

10.2. When activating the license on a new server, the license on the previous server may be automatically deactivated.

10.3. The Customer is responsible for planning migrations and infrastructure changes. Activation/deactivation may require connectivity to the central license server.

11) License verification and minimal telemetry (heartbeats)

11.1. The Software may periodically communicate with the License server to:

  • validate license status and prevent unauthorized concurrent use,
  • retrieve/validate plan limits,
  • send minimal capacity telemetry (e.g. concurrent calls and agent slots in use).

11.2. These communications do not include call content, audio, transcripts, prompts, dialed numbers, or personal data of the Customer's end users.

11.2 bis. Unavoidable technical metadata: as with any web service, the License server may receive technical connection metadata (e.g. source IP address, HTTP headers, timestamp) required to establish the connection and protect the service (security, fraud and abuse prevention). We do not use this metadata to reconstruct call content or obtain end-user data. Processing and retention, where applicable, align with the Privacy Policy.

11.3. Deliberate or persistent blocking: if the Customer deliberately (or persistently) blocks these communications, or manipulates verification mechanisms, this may result in limitations, degradation, suspension or deactivation due to inability to verify the license, without prejudice to section 11.5 for temporary connectivity incidents. For purposes of this section, "persistent" means a verification failure exceeding the applicable tolerance window ("offline grace") according to the Plan.

11.4. Compliance verification and audits (B2B): in case of reasonable indications of license non-compliance (e.g. limit circumvention or unauthorized use), we may request strictly necessary information from the Customer, preferably aggregated and remote, to verify compliance (e.g. capacity metrics and installation status). This verification will not include access to Customer systems or on-site audits unless expressly agreed in writing. We may perform this verification at most once every 12 months per license, except in cases of reasonable suspicion of non-compliance, anti-fraud incidents, or legal requirements. If the Customer unreasonably refuses, we may suspend the license until a reasonable verification is restored. Any extraordinary assistance (e.g. meetings, custom reports, or third-party audit) may be subject to fees and/or cost coverage by the Customer if agreed.

11.5. Connectivity incidents: if the Software cannot contact the License server due to temporary causes (network, DNS, firewall, third-party outages, or maintenance), the Software may attempt to continue functioning for a reasonable tolerance window ("offline grace") and may apply progressive limitations depending on implementation and Plan. We will not limit or stop features due to obvious transient errors until retries and the tolerance window are exhausted, except in cases of reasonable indications of fraud or license circumvention. The Customer acknowledges that, in self-hosted environments, this verification may be necessary to prevent fraud and ensure compliance with Plan limits.

11.6. Invalid license vs ambiguous verification failure: if the License server confirms the license is invalid (e.g. expired, revoked, or active on another server when the Plan does not allow it), the Software may immediately limit or disable features, including preventing new calls and/or starting new agents (calls in progress may end depending on implementation). When the verification failure is ambiguous (e.g. transient error), a tolerance or technical "grace" window (e.g. minutes or hours depending on the Plan) may apply before limiting new calls and/or stopping agent activity.

12) Self-hosting: Customer responsibility

12.1. The Software runs in the Customer environment. The Customer is responsible for their server, network, security, backups, OS updates, certificates, configuration and monitoring.

12.2. We are not responsible for incidents arising from the Customer's infrastructure or third-party providers (telephony, SIP, cloud, LLMs, STT/TTS, etc.). In particular:

  • the Customer is solely responsible for contracting, configuring and complying with the terms of third-party services integrated with the Software;
  • requests to third-party APIs/services are executed from the Customer server, without going through the Provider;
  • the Provider is not responsible for changes, interruptions or discontinuations of third-party services or their impact on Software operation;
  • data sent by the Customer to third-party services is outside the Provider's responsibility scope.

12.3. We are not a telephony/communications provider: the Software acts as an orchestrator and does not provide electronic communications services nor numbering, call termination, SIP trunks or routing. The Customer (or their providers) is responsible for telephony and any related obligations (contractual, technical and regulatory).

13) Updates and compatibility

13.1. We may release updates (including security updates). Unless there is a maintenance/SLA agreement, we do not guarantee any minimum frequency.

13.2. The Customer is responsible for applying updates and configuration changes needed to maintain compatibility and security.

14) Support (if applicable)

14.1. Support may vary by subscribed plan. Details: contact@kallflow.com or as indicated at checkout.

14.2. The Provider may require minimal technical information to diagnose incidents (e.g. versions, non-sensitive logs, activation status).

14.3. Support with exceptional access: if, exceptionally, resolving an incident requires accessing Customer systems or reviewing logs that may contain personal data, this will only be done with the Customer's express authorization, for a limited time and with the minimum necessary scope. Where applicable, such support will be governed by a data processing agreement (DPA) or equivalent terms, and the Customer will seek to provide minimized and/or anonymized logs where possible.

15) Acceptable Use Policy (AUP) - voice agents

15.1. It is prohibited to use the Software for:

  • fraud, phishing, scams, impersonation or social engineering,
  • spam, illegal robocalls or unsolicited communications contrary to applicable laws,
  • recording or processing personal data without a legal basis and/or without required notices/consents,
  • infringing third-party rights (privacy, intellectual property, trade secrets, etc.).

15.2. If we detect or receive reasonable indications of prohibited use or use that creates legal or security risk, we may suspend or deactivate licenses and/or Portal access.

15.3. Telecom compliance, fraud and identification: the Customer is solely responsible for: (i) holding ownership or lawful usage rights for the phone numbers, trunks and routes used; (ii) complying with applicable telecom and marketing laws (General Telecommunications Law, LSSI, etc.), including those for commercial communications and automated calls; (iii) configuring the Software (prompts/voice scripts) to clearly inform at the start of the call that the user is interacting with an AI system and, where applicable, that the call is recorded, in compliance with the GDPR; (iv) not using "CLI Spoofing" techniques (caller ID spoofing) for fraudulent purposes. The Customer warrants that the displayed number (Caller ID) corresponds to a line they have lawful rights to use. (v) where required, enabling operational compliance mechanisms (e.g. unsubscribe/opt-out handling, respecting suppression lists and preferences, time restrictions and/or prior consents) and retaining reasonable evidence of compliance; (vi) providing end users with the information and rights required by the GDPR (first-layer notice in the call and/or alternative channels where applicable), assuming the role of controller for end-user personal data.

15.4. No emergency services / high-risk uses: the Software is not designed or authorized for emergency services (e.g. 112/911) or for activities where an error could cause serious personal injury or significant material/environmental damage. The Customer assumes all risk for such uses.

15.5. Artificial Intelligence and regulatory obligations (AI Act):

a) Provider role: the Provider acts as the provider of the Software that contains or enables integration of AI systems. The Provider is not responsible for the creation, configuration or deployment of voice agents by the Customer.

b) Customer (Deployer) role: the Customer, as deployer, is solely responsible for complying with applicable laws in their territory and, in particular, for:

  • informing end users that they are interacting with an AI system (not a human), including the transparency obligation under Art. 50 of the AI Act, where applicable;
  • ensuring agents do not use subliminal or manipulative techniques or exploit vulnerabilities.

c) Technical documentation: the Provider may provide reasonable technical documentation to help the Customer meet deployer regulatory obligations.

d) AI-specific prohibitions: it is prohibited to create or operate agents that:

  • impersonate real persons without consent;
  • use synthetic voice or voice cloning (when available) to create deepfakes or impersonate identities;
  • use emotion/sentiment analysis to manipulate, discriminate or exploit vulnerabilities.

e) Emotion recognition (future): if the Software includes emotion analysis features (via transcripts or other mechanisms), the Customer is responsible for assessing and complying with additional applicable requirements and adequately informing end users.

f) Future-proofing: the Customer commits to adapting to AI regulatory changes affecting voice agent deployment, and the Provider may update these Terms to reflect new regulatory obligations.

g) Content marking: the Customer shall not remove, hide or alter any technical watermark or metadata the Software may include to identify content as AI-generated, in line with Art. 50 of the AI Act.

h) Exclusion of High-Risk AI Systems: the Software has not been designed, assessed or certified for use as a "High-Risk AI System" (as defined in Annex III of the EU AI Act or equivalent regulation), such as in critical infrastructure, hiring, credit scoring or essential services. The Customer assumes all responsibility and risk if they decide to use it in such domains.

16) Intellectual property and third-party components

16.1. The Software and Documentation are owned by the Provider or its licensors. You acquire no ownership rights, only a limited right of use.

16.2. The Software may include third-party components, including open-source libraries and dependencies (e.g. frameworks, SDKs or client services) and/or components subject to third-party licenses. Such third-party licenses may include attribution obligations, notices and/or other conditions applicable to the specific component.

16.3. Third-party notices and attributions: we will provide, along with the distribution of the Software and/or Documentation, the notices and attributions required under applicable licenses. The Customer agrees not to remove or hide intellectual property notices, attributions or licenses included with the Software.

16.4. No affiliation with third parties: using or integrating third-party technologies, brands or services (e.g. telephony providers, STT/TTS, LLMs or frameworks) does not imply affiliation, sponsorship or endorsement by those third parties, unless expressly stated.

17) Confidentiality

17.1. Definition: "Confidential Information" means any information (oral, written, technical or commercial) disclosed by one party to the other in connection with these Terms, including (without limitation): license keys, billing data (address, Tax ID), prices or negotiated terms (e.g. Enterprise), technical architecture, and any information marked as confidential or that should reasonably be understood as confidential due to its content or circumstances.

17.2. Obligations: the receiving party agrees to:

  • use Confidential Information solely to perform or enforce these Terms;
  • not disclose it to third parties except to staff, advisors or subcontractors who need to know it and are subject to equivalent confidentiality obligations;
  • protect it with measures no less than those used for its own confidential information and, in any case, no less than reasonable measures.

17.3. Exclusions: Confidential Information does not include information that the receiving party can demonstrate:

  • was already public without breach of these Terms;
  • was legitimately known before receipt;
  • was independently developed without using Confidential Information;
  • was legitimately received from a third party without confidentiality obligation.

17.4. Disclosure by legal requirement: the receiving party may disclose Confidential Information to the strictly necessary extent required by law, regulation or order of a competent authority. Where permitted by law, it will notify the other party in advance to give an opportunity to limit or challenge disclosure.

17.5. Term: these confidentiality obligations remain in effect during the contract term and for three (3) years after termination or expiration.

18) Data protection and privacy (summary)

18.1. To manage the Portal, subscriptions, billing and licenses, we process data such as: account email, billing data, payment history and license identifiers.

18.2. Minimal telemetry may be associated with a license and, indirectly, its owner (e.g. via the account email). Therefore, it is processed proportionately for limited purposes (licensing, anti-fraud, plan limits).

18.3. In self-hosted environments, we do not access call content or end-user data of the Customer.

18.4. More information: Privacy Policy at https://kallflow.com/en/privacy and Cookie Policy at https://kallflow.com/en/cookies.

18.5. Customer end-user data: since the Software is self-hosted, the Provider generally does not act as a processor for the Customer's call content, audio or transcripts, unless explicitly agreed (e.g. support involving temporary access to logs) and, where applicable, under a separate DPA.

18.5 bis. Customer GDPR responsibility (end users): the Customer acknowledges that it generally acts as controller for personal data of its end users (e.g. phone numbers, audio, transcripts, agent logs, recordings and outcomes). The Customer is solely responsible for: (i) having a valid legal basis (consent, contract performance, legitimate interest, etc.), (ii) meeting information/transparency duties and rights handling, (iii) determining retention periods and security measures, and (iv) entering into required agreements with its providers (SIP/telephony, STT/TTS, LLMs, etc.) when they act as processors or joint controllers.

18.5 ter. Support minimization: if the Customer provides us data or logs for support, it will ensure they contain the minimum necessary and, where possible, are anonymized or pseudonymized. The Customer confirms it has the right to share this information with the Provider for support purposes.

18.6. License server (EEA): the Provider's license server is located within the European Economic Area (Germany). For operation of the licensing system, no personal data transfers outside the EEA are expected.

18.7. Stripe: payment processing is performed via Stripe, which processes data under its own terms and policies. Stripe may process data outside the EEA under its safeguards and transfer mechanisms (e.g. Standard Contractual Clauses).

18.8. International sales: for sales outside the EU/EEA, data processing is governed by the laws applicable in the Customer's territory, and the Customer is responsible for its own compliance regarding Software use.

18.9. Pending documents: these Terms reference a Privacy Policy and a Cookie Policy, which must be kept up to date under applicable regulations.

19) Warranties and disclaimer ("as is")

19.1. To the maximum extent permitted by law, the Software and the Portal are provided "as is" and "as available".

19.2. We do not warrant that the Software is uninterrupted, error-free, or compatible with any infrastructure, especially in self-hosted environments and those dependent on third parties.

19.3. Nothing in these Terms limits warranties that cannot be excluded by law.

19.4. Consumers (B2C): where the buyer acts as a consumer, the statutory conformity/warranty regime described in the Consumer Annex (especially A7) and mandatory consumer laws apply. Nothing in this section 19 excludes or limits those rights.

19.5. Limited IP warranty and indemnity (B2B): the Provider states that, to its reasonable knowledge at delivery, the Software does not infringe third-party intellectual property rights. If a third party claims IP infringement arising from use of the Software as delivered by the Provider, the Provider will indemnify the Customer (subject to the cap and exclusions in section 20) provided that: (i) the Customer promptly notifies the claim, (ii) the Customer did not modify the Software in a way that causes infringement, and (iii) the Customer reasonably cooperates in the defense. The Provider may, at its option: (a) obtain the right to continue using the Software, (b) modify it to avoid infringement, or (c) terminate the contract and refund proportionally any unused prepaid amounts.

20) Limitation of liability (12-month cap)

20.1. To the maximum extent permitted by law, we shall not be liable for indirect, special, consequential or punitive damages, including (without limitation) lost profits, loss of data, business interruption or reputational harm.

20.2. In any case, the Provider's total aggregate liability arising out of or related to these Terms (contract, tort, negligence or any other theory) is limited to the total amount actually paid by the Customer to the Provider during the twelve (12) months immediately preceding the event giving rise to the claim.

20.3. This limitation does not apply in cases of willful misconduct, gross negligence, breach of essential contractual obligations, personal injury, or other non-limitable cases under law.

20.4. Consumers (B2C): exclusions and limitations in this section apply only to the extent permitted by mandatory consumer laws.

21) Indemnification

The Customer will indemnify and hold the Provider harmless against third-party claims, administrative sanctions or fines imposed by regulatory authorities arising from:

  • the Customer's use in breach of these Terms or the law,
  • data, prompts, audio or content provided by the Customer,
  • communications/calls operated by the Customer and their regulatory compliance.

The Provider may assume control of the defense of an indemnified claim (with reasonable cooperation from the Customer). The Customer will not admit liability or settle without the Provider's prior written consent where the Provider's interests are affected.

22) Force majeure

Neither party will be liable for failures due to causes beyond its reasonable control for the duration of such cause, including (without limitation): major internet outages, natural disasters, governmental acts, pandemics, large-scale cyberattacks, international sanctions, or failures of critical third-party providers (e.g. cloud, LLMs).

If the force majeure situation lasts more than ninety (90) calendar days, either party may terminate the contract by written notice, with no party entitled to compensation for the termination itself. If there are prepaid amounts, they will be refunded proportionally for unused periods.

23) Suspension and termination

23.1. We may suspend or terminate access to the Portal, updates, support or licenses in case of non-payment, material breach, prohibited use or attempt to circumvent licensing.

23.2. Post-termination / expiration obligations: upon termination or expiration of the subscription, the license is deactivated (voice agents may not start and active ones may stop depending on implementation). The Customer retains the installed Software on its server and all its data (conversations, audit logs, agent configurations, etc.), but may not start agents or features requiring an active license. If the Customer reactivates a subscription, the license will be reactivated and operation may resume with existing data/configurations. In case of termination due to fraud, license circumvention or serious material breach, the Provider may permanently revoke the license.

23.3. Exports and sanctions: the Customer represents it will comply with applicable export control and economic sanctions laws (including EU rules), and will not use the Software in a way that violates such obligations.

24) Changes to the Terms

We may update these Terms for legal, security or product reasons. We will notify you via the Portal and/or email at least thirty (30) calendar days before the new Terms take effect. If you do not agree, you may cancel renewal and stop using the Software. Consumers (B2C): if the change is material, you may terminate without penalty.

25) Severability

If any clause is deemed invalid or unenforceable, the remaining Terms remain in force and will be interpreted to preserve the original intent to the extent possible.

26) Governing law and jurisdiction

26.1. Governing law: Spain (and mandatory EU law where applicable).

26.2. Jurisdiction: courts of Girona, except where mandatory law requires a different forum (especially for B2C).

26.3. Customers outside the EU/EEA: for Customers outside the EU/EEA, Spanish law applies, without prejudice to mandatory rules in the Customer's territory that cannot be excluded by agreement.

26.4. Certain territories may impose additional requirements (e.g. CCPA in California). The Customer is responsible for assessing its own local compliance regarding Software use.

27) Contact

  • Legal/contract: contact@baselinksl.com
  • Support: contact@kallflow.com

28) Notices and communications

28.1. We may communicate with you by email, through the Portal, or through other channels indicated at checkout. Email notices are deemed delivered when sent to the account email and no delivery error is recorded, without prejudice to mandatory B2C rights and the ability to prove non-receipt.

28.2. The Customer is responsible for keeping a working contact email and ensuring our communications are not blocked (e.g. by spam filters).

29) Assignment and subcontracting

29.1. The Customer may not assign this contract or its license without the Provider's prior written consent, except in case of corporate restructuring (merger, demerger or global asset transfer) provided the assignee accepts these Terms and the Customer remains responsible for any amounts due up to the assignment date.

29.2. The Provider may subcontract non-essential parts of the service (e.g. payment processing) or assign the contract as part of a reorganization, acquisition or asset transfer, while preserving mandatory Customer/consumer rights (especially B2C). In case of assignment, the assignee will assume all obligations under these Terms toward the Customer/consumer, including active subscriptions, terms and conditions, and the Provider will notify the Customer/consumer within a reasonable time. Where subcontracting involves personal data processing, it will be done with appropriate safeguards and, where applicable, under processing/sub-processing agreements in line with the Privacy Policy.

30) Beta/Preview features

30.1. Features marked as "beta", "preview" or "experimental" are provided without any warranty of availability, stability, continuity or performance.

30.2. The Provider may change or withdraw Beta features at any time without notice.

30.3. No SLA or support obligation applies to Beta features unless expressly agreed in writing.

30.4. Use of Beta features is voluntary and at the Customer's risk.

31) Publication and benchmarking restrictions

31.1. The Customer shall not publish benchmarks, performance tests, comparisons or evaluations of the Software without the Provider's prior written consent.

31.2. This restriction does not apply to information the Customer shares internally within its organization for purchasing or operational decisions.

31 bis) Commercial references (client list)

31 bis.1. Unless the Customer objects in writing (e.g. via contact@baselinksl.com), the Provider may mention the Customer's trade name and/or logo as a commercial reference (e.g. client list on the website or presentations). This mention does not imply any technical, commercial or legal endorsement by the Customer.

31 bis.2. The Customer may revoke this authorization at any time, and the Provider will remove the reference within a reasonable period (e.g. 30 days), except where it must be retained in already published materials or due to legal obligations.

35) Affiliate program (if applicable)

35.1. The Provider may offer an affiliate program. Participation may be subject to additional conditions (e.g. affiliate terms, branding rules and anti-fraud criteria) which, if accepted, are incorporated by reference.

35.2. Affiliates are not authorized resellers and have no authority to represent, bind or assume obligations on behalf of the Provider. Any commercial representation must be clear and not misleading.

35.3. We reserve the right to suspend or cancel participation and/or commissions when we detect (or have reasonable indications of) fraud, self-referrals, abuse, misleading advertising, or breach of the program conditions.

32) Survival clause

32.1. Upon termination or expiration, the following survive: Intellectual property (16), Confidentiality (17), Data protection (18), Warranties and exclusions (19), Limitation of liability (20), Indemnification (21), Governing law and jurisdiction (26), outstanding payment obligations, and any other clause that by its nature should survive.

33) Entire agreement

33.1. These Terms (including the Annexes) constitute the entire agreement between the parties regarding their subject matter and replace any prior agreement, negotiation or communication, oral or written.

33.2. This section does not replace specific written agreements (e.g. individually negotiated Enterprise SLAs), which are considered additions or agreed modifications to these Terms.

34) No waiver

34.1. Failure or delay by either party to exercise a right under these Terms does not constitute a waiver of that right or any other right. Partial exercise does not prevent future exercise.

Consumer Annex (B2C)

This annex applies only when the buyer acts as a consumer.

A1) Right of withdrawal (general rule)

If you purchase as a consumer, you have the right to withdraw from the contract within fourteen (14) calendar days from its conclusion, without needing to provide any reason.

To exercise withdrawal, you must communicate it unequivocally to contact@baselinksl.com, indicating:

  • the account email,
  • order/invoice identifier,
  • purchase date.

A2) Exception for digital content with immediate access (loss of withdrawal)

Our product is delivered with immediate access to download and a license key (digital content).

When the consumer:

  1. expressly requests that supply begins immediately, and
  2. acknowledges that, once supply begins, they lose the right of withdrawal,

then the withdrawal right does not apply once supply has started.

Legal note (informative): this exception aligns with article 16(m) of Directive 2011/83/EU (consumer rights) and the corresponding exception under Spanish law for withdrawal on digital content (TRLGDCU).

A3) Checkbox texts (required at B2C checkout)

At checkout, before immediate access, these checkboxes must be shown (not pre-checked):

  1. I request that the supply of the digital content begins immediately (access and key).
  2. I understand and accept that, once the immediate supply of the digital content begins, I lose my 14-day withdrawal right.
  3. I have read and accept the Terms and Conditions and the Privacy Policy.

A4) If the exception is not activated

If, for any reason, supply has not started and/or the above consents have not been properly collected, the consumer may exercise withdrawal within the applicable legal period.

A5) B2C refunds (when withdrawal applies)

If withdrawal is valid (because the digital content exception was not applied), we will refund payments received from the consumer as required by applicable law and using the same payment method, unless otherwise agreed.

A6) Model withdrawal form (optional)

(You only need to fill in and send this form if you want to withdraw from the contract and if withdrawal applies.)

  • To the attention of: BASELINK, SL, Carrer Puig Sureda, 36, contact@baselinksl.com
  • I/We (_) hereby give notice that I/We (_) withdraw from my/our (_) contract of sale of the following digital content:
  • Order/invoice number:
  • Purchased on:
  • Consumer name:
  • Consumer address:
  • Consumer signature (only if submitted on paper):
  • Date:

(*) Delete as appropriate.

A7) Conformity, updates and statutory guarantees (B2C)

Without prejudice to the rest of this document, when you contract as a consumer the statutory conformity regime for digital content and services under applicable consumer law applies (TRLGDCU and any implementing/replacing rules).

In particular:

  • if the digital content/service is not in conformity with the contract, you have the right to the statutory remedies (bringing into conformity, and where applicable, price reduction or contract termination) under the legal terms and limits;
  • where applicable, we will provide necessary updates to maintain conformity (including security updates) within the scope of the contracted supply and within legally required periods, without this implying an obligation to add new uncontracted features;
  • we will not be responsible for lack of conformity resulting exclusively from failure to install updates we provided, provided that we informed you of their availability and the consequences of not installing them and that non-installation was not due to deficiencies in the installation instructions.

A8) Alternative dispute resolution (ADR/consumer)

You may contact the competent consumer authorities and bodies in your territory to receive information about out-of-court dispute resolution mechanisms (e.g. consumer arbitration systems), where applicable.

Informative note: the European Online Dispute Resolution (ODR) platform was discontinued on 20 July 2025. Therefore, if it is mentioned elsewhere, it may no longer be available.
