Terms of Service

These Terms of Service (“Terms”) apply to Biel.ai accounts, subscriptions, AI chat, search, APIs, integrations and related services (the “Services”). Volcanic Labs SLU (“Biel”, “we” or “us”) provides the Services. You accept these Terms when you agree to them while creating an account or placing an order. If you act for an organization, you confirm that you can enter into this agreement on its behalf. A paid subscription and paid extra usage each require the separate authorization described below.

You can save or print this page for your records. A signed order or separately negotiated agreement may contain different terms. Section 20 explains which document takes priority if they conflict.

1. Accounts and eligibility

The Services are intended for business and professional use. Provide accurate account and billing details, keep your credentials secure and promptly report unauthorized access. You are responsible for the people you authorize to use your account. Nothing in these Terms removes rights that apply to you under mandatory law.

2. Use of the Services

You may use the Services only in accordance with these Terms, the documentation and applicable law. You must not:

• Use the Services for unlawful, fraudulent, harmful or abusive activity.
• Infringe another person's privacy, confidentiality or intellectual property rights.
• Access accounts or systems without authorization.
• Interfere with the security, integrity or performance of the Services.
• Reverse engineer or bypass technical restrictions, except where applicable law allows it.
• Submit content you do not have the right or lawful basis to process.

3. Customer content and generated output

You retain your rights in submitted documentation, messages, prompts and other content (“Inputs”). Generated answers are “Outputs”. Together, these are “Customer Content”. We assign you any transferable rights Biel holds in Outputs. Outputs may not be unique or protected by intellectual property law, and this assignment does not transfer third-party rights.

You give Biel a limited, non-exclusive licence to process Customer Content to provide, secure, support and maintain the Services and meet legal obligations. You must have the rights and lawful basis to submit Inputs and use Outputs. We do not use indexed content or end-user conversations to train AI models.

We may use aggregated statistics that do not identify you, your users or Customer Content. Personal data remains subject to section 5 and the DPA.

4. AI-generated content

AI answers may be incomplete, inaccurate or unsuitable. Source links and configuration controls support review but do not guarantee correctness or fitness for a purpose. Apply human review proportionate to the consequences, particularly for legal, medical, financial, safety-critical or other high-impact decisions.

Biel remains responsible for its legal duties as a provider. You are responsible for your deployment, required notices and access controls. Where required, tell people they are interacting with AI. Do not obscure required disclosures. When an external assistant uses Biel’s MCP tools to retrieve documentation, that assistant may generate its own response.

5. Privacy and data processing

Our Privacy Policy explains when Biel processes personal data as a controller. When we process personal data on your behalf, our Data Processing Agreement (“DPA”) applies unless we have signed a different DPA with you. Accepting these Terms is not consent to every processing activity. We request consent separately when the law requires it.

6. Third-party services and AI providers

Biel uses third-party infrastructure, integrations and AI providers. Geographic or provider restrictions may affect availability. Follow restrictions communicated in the Services or documentation. We may replace providers or models where reasonably needed to operate, secure or improve Biel, subject to the DPA’s notice and objection rules for personal-data processing. See the provider list.

7. Fees, renewal and taxes

Your order or checkout shows the subscription price, currency, billing period and included usage. Public plans are listed on our Pricing page. Unless stated otherwise, prices exclude applicable taxes. When you buy a subscription, you authorize Biel and its payment provider to charge your saved payment method for the agreed subscription fees and taxes. Paid extra usage requires a separate opt-in under section 10.

Subscriptions renew automatically for the same monthly or annual period until canceled. Cancel from the dashboard before the next renewal to prevent the next subscription charge. Access continues until the end of the current paid period, subject to these Terms. We will give at least 30 days' notice of a subscription price increase. It takes effect at the first renewal after that notice period. An increase to an extra-usage rate requires your separate agreement before we charge the higher rate.

8. Trials, cancellations and refunds

• Free trials. Eligibility and duration are shown when you sign up. Unless a payment method and a separate automatic-renewal offer are presented, the standard trial does not create a paid subscription automatically.
• Monthly subscriptions. Payments are non-refundable once charged, except where applicable law or these Terms require otherwise. Access continues until the end of the paid month after cancellation.
• First annual payment. Your first annual subscription payment is non-refundable, except for billing errors or where applicable law or these Terms require a refund.
• Annual renewals. You may request a full refund of the renewed subscription fee within 15 days after an annual renewal. After that period, the renewal is non-refundable and access continues until the end of the subscription year, except where applicable law or these Terms require otherwise. If we refund an annual subscription fee in full, the refunded subscription ends.
• Extra usage. Charges for billable interactions already used are non-refundable, except for billing errors or where applicable law or these Terms require otherwise. A subscription refund does not include correctly billed extra usage. Disabling extra usage or canceling your subscription does not cancel charges already incurred. Interactions accepted before a limit change or before extra usage is disabled may finish and be charged.
• Billing errors. Contact [email protected] with the invoice details if a charge is incorrect or duplicated. We will investigate and correct confirmed errors, including refunding amounts incorrectly collected.
• Failed payments. We may retry an authorized payment. Extra-usage payment problems follow section 10. An unpaid base subscription may affect access separately, after notice and an opportunity to resolve the issue where practicable.

To request a refund, contact [email protected]. These policies do not limit mandatory withdrawal rights or remedies for services that do not conform to the contract. Refunds of unused prepaid fees when Biel terminates without cause are covered by section 14.

9. Programs and promotions

Biel may offer discretionary programs and promotions from time to time. A program may be active, paused or unavailable. Participation requires approval and continued eligibility under the conditions of the applicable offer.

• Open Source program. When available, eligible non-commercial open-source projects may receive free or discounted access, subject to approval and the offer's eligibility and attribution requirements.
• Startup program. When available, eligible startups may receive a discretionary discount. The discount, duration, eligibility and other conditions depend on the promotion available when we approve the application and are confirmed in writing before purchase.
• We may request reasonable eligibility information, decline applications or withdraw an offer obtained through inaccurate information. Offers cannot be combined unless we agree otherwise.
• We may change, pause or end programs for future applicants. We will honor the agreed duration and conditions of an offer already approved, provided you continue to meet its requirements. Fees and renewal terms after an offer ends are disclosed before purchase.

10. Included usage and extra interactions

Allowances and authorisation

Your order sets the included interactions, indexed pages and features. Unless agreed otherwise, allowances are shared across your team’s projects. Chat, search and integrations share the interaction allowance. Reasoning and continuations may use multiple billable units. Extra usage adds interactions, not indexed pages or plan features.

Extra usage is off by default. An authorised administrator must enable it in subscription settings, accept the rate and authorise charges to your saved payment method. The standard rate is US$0.05 per billable interaction unit unless you expressly agree otherwise. Buying a subscription does not enable it.

Payment and spending limits

Authorised extra interactions become payable when used. We collect monthly for the previous UTC calendar month, or earlier at US$25 in uncollected charges, whichever comes first, separately from subscription fees. Prior-month balances below US$1 may carry forward until they reach US$1. Balances awaiting scheduled collection are not overdue. Grace arrangements affect access, not payment due dates.

You can set a monthly spending limit. Zero stops new paid extra interactions. Blank means no customer-set spending limit. This is not prepayment. Your limit applies during any grace period, and work accepted before a limit change or pause may finish and be charged.

For finite limits, alerts apply at 80% and 100% of included interactions plus extras permitted by your spending limit. With extras off or set to zero, alerts use the included allowance. Uncapped extras have no percentage alerts. Set a spending limit to control costs.

Failed payments and manual review

Support reviews failed collections and may contact your billing administrator about payment or bank authentication. Failure alone does not automatically pause extras. Continued use requires your authorisation, an eligible paid subscription and room within your spending limit.

• Support reviews US$100 of unpaid extra usage attributable to one UTC calendar month, or US$200 unpaid across all months.
• The UTC calendar month of the first unsuccessful collection is grace month one, followed by month two. If an overdue balance remains after month two, support reviews the account and may manually disable extras. An October failure means review from December if still overdue.

These are review thresholds, not automatic caps or free allowances. All authorised usage remains payable, including amounts above a threshold. Cancelling or pausing extra usage does not cancel charges already incurred. A pending or uncertain payment alone does not start the clock. Retrying or changing cards does not restart it. Paying all overdue extra-usage charges resolves that grace episode. Contact support to resume extras after a pause.

A pause for unpaid extras preserves included interactions while the base subscription is paid and active. Your spending limit and separate security, unlawful-use or unpaid-subscription restrictions still apply. We give notice of manual payment pauses where practicable. See section 14 for other restrictions.

11. Confidentiality

Each party will protect the other's non-public information with at least reasonable care and use it only to perform this agreement. This does not cover information that becomes public without a breach, was already lawfully known without restriction, is lawfully received from another source or is independently developed. A legally required disclosure is allowed, with advance notice where permitted. On request after termination, each party will return or delete confidential information, subject to legal retention duties, protected backup cycles and the DPA.

12. Intellectual property and feedback

Biel and its licensors retain their rights in the Services, software, documentation, branding and underlying technology. You receive the right to use the Services during the agreed term, subject to these Terms and your order. If you choose to give product feedback, you allow us to use it worldwide without paying a royalty, including after the subscription ends. We will not identify you or disclose your confidential information when using that feedback without your permission.

13. Availability and warranties

We work to keep the Services available and secure, but cannot guarantee uninterrupted or error-free operation. Except for express commitments in your agreement and warranties that cannot legally be excluded, the Services are provided “as is” and “as available”. A service-level agreement applies only if expressly agreed. This section does not remove our obligations under the DPA or mandatory law.

14. Suspension and termination

We may restrict affected access when reasonably necessary to prevent harm, address a security risk, respond to unlawful use or enforce these Terms. Payment-related restrictions follow sections 8 and 10. Where practicable, we will explain the reason and give you an opportunity to resolve it. An extra-usage review does not automatically cancel your subscription.

Either party may terminate for a material breach if the other party does not remedy it within 30 days after written notice describing the breach. We may act immediately for a serious breach that cannot reasonably be remedied, such as fraud, illegal activity or a material security threat. Repeated breaches after notice may also justify termination.

We may discontinue the Services or terminate without cause on at least 30 days' notice. If we end a prepaid period without cause, we will refund the unused prepaid subscription fees. Customer Personal Data is returned or deleted under the DPA and your order. Charges already incurred and provisions intended to continue, including confidentiality, intellectual property, liability and dispute provisions, survive termination.

15. Customer names, logos and case studies

During your subscription, you allow us to identify you as a customer and use your name and logo in customer lists and related promotional materials. You may opt out of future use by contacting [email protected].

We may reproduce public reviews or testimonials only where the applicable platform terms and third-party rights allow it, without changing their meaning or disclosing confidential information. Publishing a case study with non-public usage information, new attributed quotes or customer-specific performance claims requires your prior written approval.

16. Limitation of liability

To the maximum extent permitted by law, neither party is liable for indirect, incidental, special or consequential loss, or for lost profits, revenue, goodwill or data, arising from the Services. Each party's total aggregate liability arising from the Services is limited to the fees paid by you to Biel for the affected Services during the 12 months preceding the event giving rise to the claim.

These exclusions and limits do not excuse payment of agreed fees or charges already incurred. They do not apply to fraud, deliberate misconduct or liability that cannot lawfully be limited. They do not limit a person's mandatory data-protection rights or regulatory powers. Different liability terms in a signed agreement take priority, subject to applicable law and the DPA.

17. Customer indemnity

You will defend Biel against third-party claims caused by your Customer Content or deployment infringing third-party rights, your failure to give legally required notices or establish a lawful basis for processing, or your breach of these Terms. You will cover damages, settlements you approve and reasonable legal costs resulting from those claims, subject to section 16. This does not cover a claim to the extent caused by Biel's own breach or unlawful conduct. We will promptly notify you, provide reasonable cooperation at your expense and let you control the defense. A settlement that admits fault by Biel or imposes a non-monetary obligation on us requires our written consent.

18. Governing law and disputes

Spanish law governs these Terms, subject to mandatory rules that apply to you. Each party will make a reasonable effort to resolve a dispute informally before bringing a claim, without losing the right to urgent relief or allowing a legal deadline to expire. Disputes go to the courts that have jurisdiction under applicable law. A different court may be chosen only by a separately negotiated agreement that is legally valid.

19. Changes to these Terms

We may update these Terms as the Services, law or business operations change. We will post the revised text and its date. For changes that materially affect an existing customer's rights or obligations, we will give at least 30 days' advance notice by email or another durable account notice. Unless mandatory law requires an earlier change, material changes apply at the first subscription renewal after that notice period. You may cancel before renewal if you do not agree.

Changes strictly needed to comply with law or address an urgent security risk may take effect earlier, with notice as soon as reasonably possible. We do not apply new charges or higher rates retroactively. Extra-usage rate increases still require the separate agreement described in section 7. Changes to personal-data processing remain subject to the DPA and applicable law.

20. General and document priority

Neither party is responsible for delay caused by events beyond its reasonable control, but this does not erase charges already incurred. If a clause cannot be enforced, the rest of the agreement continues. Not enforcing a right immediately does not waive it. You may assign this agreement with our written consent. We may assign it to an affiliate or a successor in a financing, merger, reorganization, acquisition or business sale, provided that the assignee assumes our obligations. We will notify you of a change in the contracting provider.

A signed order or separately negotiated agreement takes priority over these Terms where it expressly addresses the same issue differently. For processing Customer Personal Data, the DPA takes priority. Applicable Standard Contractual Clauses take priority over conflicting DPA terms. The Privacy Policy explains controller processing and does not replace your contract or the DPA. These Terms, the applicable DPA and any agreed order form make up the agreement for the Services and replace earlier discussions about the same subject. We may send contractual notices to your account or billing email. Keep those details current. Contact us if you need a copy of the terms accepted for your account.
