Terms of Service

These Terms of Service (“Terms”) govern your access to and use of the Tero platform accessible at app.tero.legal (“the Platform”), operated by Tero Legal ApS, a Danish private limited company (“Tero”, “we”, “us”, or “our”). By creating an account or using the Platform, you agree to be bound by these Terms on behalf of yourself and the organisation you represent.

If you do not agree to these Terms, do not access or use the Platform.

Definitions

These are the key terms used throughout this agreement — refer back here whenever you see a capitalised word like 'Customer', 'User', or 'Legal Content'.

Account Registration and Access

You need a valid account to use the platform. Each person must have their own named licence — accounts cannot be shared.

You need a valid account to use the platform. Each person must have their own licence — sharing is not allowed.

Eligibility

The Platform is intended for use by legal professionals and organisations engaged in legal work. By registering, you represent that you are authorised to bind the Customer to this Agreement.

Account credentials

The Customer is responsible for maintaining the security and confidentiality of all account credentials and for all activity conducted under its account. Any suspected or confirmed unauthorised access must be reported to Tero immediately at support@tero.legal.

Individual licences and reassignment

Each User must be assigned an individual, named licence. Licences may not be shared between individuals or used on a rotating basis. A licence may be permanently reassigned from one User to another only where the original User has left the Customer’s organisation or has had their authorisation revoked on a permanent basis. Temporary or recurring reassignment to allow multiple individuals to share a single licence is not permitted.

Organisational accounts

Where the Customer operates an organisational account, the Customer’s designated administrator is responsible for managing User access and ensuring all Users comply with these Terms. If the Customer is unable to revoke access for any User who is no longer authorised, it must notify Tero promptly.

Subscription and Payment

Access is paid per user per month. Invoices are due within 30 days and subscriptions renew automatically — you will get advance notice before any price change.

Access is paid and billed per user per month. Invoices are due within 30 days. We give 45 days' notice before any price increase.

Subscription fees

Access to the Platform requires a paid Subscription. Fees are set out in the applicable Order Form and are charged per User per month. Fees are quoted exclusive of VAT, which will be added where applicable under Danish law. The Customer’s obligation to pay fees is not contingent on the delivery of any future features or functionality not described in the Agreement. Service level commitments, including uptime targets and any associated service credits, are set out in the Service Level Agreement schedule attached to the applicable Order Form.

Payment terms

Invoices are due within 30 days of the invoice date unless otherwise agreed in the Order Form. If payment is not received by the due date, Tero may, following at least 10 business days’ written notice, suspend access to the Platform until the outstanding amount is settled in full. Tero will not charge late interest on amounts that are the subject of a bona fide written dispute raised by the Customer before the payment due date.

Price changes

Tero may revise Subscription fees at renewal by providing at least 45 days’ written notice before the revised fees take effect at the start of the next renewal period.

Refunds

Subscription fees are non-refundable except: (a) as required by applicable law; (b) where the Customer terminates this Agreement for cause due to a material breach by Tero in accordance with clause 9.2, in which case Tero shall refund any fees paid in advance for the unused portion of the then-current term; or (c) as otherwise agreed in writing between the parties.

Permitted Use

You can use the platform for your own legal work, but you cannot resell it, reverse-engineer it, or use it to train competing AI. Responsible and lawful use is required.

You can use the platform for your own legal work. You may not share access, reverse-engineer the software, or use it to build competing products.

Licence grant

Subject to these Terms and payment of applicable fees, Tero grants the Customer a limited, non-exclusive, non-transferable licence to access and use the Platform for the Customer’s internal legal work during the Subscription period.

Acceptable use

The Platform may only be used for lawful purposes in connection with legitimate legal practice. The Customer and its Users must not:

• provide external legal services to third parties through the Platform without Tero’s prior written consent;
• share, sublicense, sell, or otherwise transfer access credentials or rights to use the Platform to any individual who is not an authorised User;
• attempt to reverse engineer, decompile, or derive the source code or underlying model weights of the Platform;
• use the Platform or any Output to build, train, fine-tune, benchmark, or evaluate any product or system that competes with the Platform;
• upload or submit content that is unlawful, harmful, or that infringes third-party intellectual property rights;
• upload or submit payment card data, biometric data, or genetic data;
• interfere with or attempt to disrupt the availability, integrity, or performance of the Platform or its underlying infrastructure;
• circumvent any access controls, encryption mechanisms, or security measures implemented in the Platform.

Beta and preview features

Tero may make certain features available on a beta or preview basis (“Preview Features”). Preview Features are optional and the Customer is under no obligation to use them. Preview Features are provided on an “as available” basis and Tero makes no representations regarding their reliability, completeness, or continued availability. Tero may modify or withdraw any Preview Feature at any time. Tero’s obligations regarding Confidential Information, data protection, and the security of Legal Content apply to Preview Features to the same extent as to the Services generally. Tero’s total aggregate liability arising from or in connection with Preview Features shall not exceed €50,000, except for claims that cannot be limited by law.

AI Services — Important Limitations

Our AI outputs are research assistance tools, not legal advice. Always have a qualified lawyer review them before acting — Tero is not liable for reliance on AI-generated content.

Our AI outputs are for research assistance only — not legal advice. Always have a qualified lawyer review what the AI produces.

Nature of AI outputs

The Platform uses large language models and AI-assisted analysis to generate legal research, document summaries, and contract extractions. These outputs are provided for informational and research assistance purposes only. Given the probabilistic nature of machine learning, outputs may in some circumstances be inaccurate, incomplete, or not reflect current law. The Customer is responsible for evaluating the accuracy and suitability of all Output for its intended purpose, including through human review by a qualified lawyer.

No legal advice

AI-generated Output from the Platform does not constitute legal advice. Tero is not a law firm and does not practise law. Output is not a substitute for independent legal judgement by a qualified lawyer. The Customer bears sole responsibility for any decisions made in reliance on Output.

Citations and sources

Where the Platform provides citations or source references, these are generated to assist further research only. The Customer must independently verify all cited sources before relying on them in legal work, advice, or submissions.

No warranty of accuracy

Tero does not warrant that AI-generated Output will be accurate, complete, up to date, or fit for any particular legal purpose. Jurisdictional variations in law, recent legislative or regulatory changes, and the inherent limitations of language models may affect output quality.

Data, Privacy and Security

Your documents are encrypted before they reach us and we can never read them. We do not use your data to train AI models. A full DPA is included in your subscription.

Your data is encrypted on your device before it reaches us. We never see your files in plain text, and we never use your data to train AI models.

Zero-knowledge architecture

The Platform is built on a zero-knowledge storage architecture. Legal Content stored on the Platform is encrypted client-side before transmission to Tero’s infrastructure. Tero personnel hold only encrypted ciphertext and do not have the technical ability to access or read stored Legal Content. Where a User submits content to AI features within the Platform, that content is decrypted solely for the purpose of being processed by large language models accessed through AWS Bedrock, Amazon’s managed AI inference service, deployed on AWS infrastructure within the European Union. AWS acts as Tero’s sub-processor for AI query processing under the AWS Data Processing Addendum. Queries submitted to AI features are not used to train or fine-tune any underlying foundation model, and content is not retained beyond the active session. Tero’s obligations regarding Confidential Information in Section 8 and the restriction on AI training in Section 6.2 apply in full to all AI processing.

No AI training on Customer data

Tero will not use Legal Content, Input, Output, or any other Confidential Information of the Customer to train, fine-tune, evaluate, or otherwise improve any AI model, whether operated by Tero or any third party. Tero will ensure that its subprocessors and subcontractors are bound by equivalent restrictions and will not permit any subprocessor to retain or make available Legal Content or Confidential Information for human review, except cloud infrastructure providers acting solely in a storage capacity.

Data processing

Tero processes account and operational data (such as login events, usage metadata, and billing information) as a data controller under the GDPR. Our Privacy Policy, available at app.tero.legal/privacy, applies to such processing and is incorporated into this Agreement by reference.

Data Processing Agreement

To the extent that Users upload or submit personal data relating to third parties through the Platform, Tero acts as a data processor on behalf of the Customer. A Data Processing Agreement (“DPA”) is incorporated into and forms part of this Agreement with effect from the date the Customer first accesses the Platform. The current DPA is available at app.tero.legal/legal/dpa and will be provided to the Customer at account creation. The Customer is responsible for ensuring it has a lawful basis for uploading any personal data to the Platform.

EU data residency

All data associated with the Platform — including AI query processing via AWS Bedrock — is stored and processed on AWS infrastructure located within the European Union. Tero will not transfer Customer data outside the EU/EEA without the Customer’s prior written consent, except where required by applicable law.

Security measures

Tero implements appropriate technical and organisational measures to protect the Platform and account data, including encryption in transit and at rest, access controls, and regular security reviews. A summary of Tero’s security practices is available at app.tero.legal/security. Tero shall not reduce the level of security measures applied to the Platform during the term of this Agreement without the Customer’s prior written consent.

Intellectual Property

You own everything you upload. We own the platform and its underlying technology. Neither side gains rights to the other's IP just by using the service.

You own your content. We own our platform. Neither transfers to the other.

Tero’s IP

The Platform, its underlying models, software, design, and all related intellectual property rights are owned by Tero or its licensors. Nothing in these Terms transfers any ownership of Tero’s intellectual property to the Customer. Tero warrants, to its knowledge, that the Services do not infringe any third-party intellectual property rights.

Customer’s IP

The Customer retains all intellectual property rights in Legal Content. To the extent Tero acquires any rights in Legal Content in the course of providing the Services, Tero hereby irrevocably assigns all such rights back to the Customer. Tero’s right to use Legal Content is limited to what is strictly necessary to deliver the Services to the Customer under this Agreement.

Feedback

If the Customer or its Users provide feedback, suggestions, or ideas about the Platform (“Feedback”), the Customer grants Tero a perpetual, irrevocable, royalty-free licence to incorporate and use that Feedback for the purpose of improving the Platform and its services, subject always to the restrictions in Section 6.2 (no AI training on Customer data) and the confidentiality obligations in Section 8. Tero will not use Feedback to train or fine-tune any AI model. Tero will not use Feedback in a manner that identifies the Customer or any of its Users as the source without their prior written consent.

Marketing and reference rights

Tero may use the Customer’s name and logo to identify the Customer as a Tero customer in marketing materials, case studies, and public communications only where the Customer has given its prior written consent to such use. The Customer may grant or withdraw consent at any time by written notice to legal@tero.legal. Tero will cease any such use promptly upon receipt of a withdrawal notice.

Confidentiality

Both sides keep each other's confidential information strictly private and use it only for the purpose of this agreement.

Both sides keep each other's confidential information strictly private and use it only for the purposes of this agreement.

Confidentiality obligations

Each party agrees to: (a) keep the other party’s Confidential Information strictly confidential; (b) protect Confidential Information with at least the same degree of care it uses to protect its own confidential information, and in no event less than reasonable care; and (c) not use Confidential Information for any purpose outside the scope of this Agreement.

Permitted disclosure

A party may disclose Confidential Information to its employees, contractors, advisers, and subprocessors who have a genuine need to know it in connection with the performance of this Agreement, provided those individuals are bound by confidentiality obligations no less stringent than those in this Agreement. Disclosure may also be made where required by applicable law, regulation, or court order, provided the disclosing party gives the other party prior written notice to the extent permitted by law and cooperates in seeking confidential treatment.

Survival

Confidentiality obligations survive termination of this Agreement for five years. Obligations relating to Legal Content and other Confidential Information that comprises intellectual property survive indefinitely.

Term and Termination

Subscriptions renew automatically. You need 30 days' notice to cancel (we give you 90 days). After termination, your data is deleted within 30 days.

Subscriptions renew automatically unless you give 30 days' notice (we give 90). Either side can terminate for material breach with 30 days to fix it.

Subscription term and renewal

Subscriptions run for the period set out in the Order Form. Unless either party gives written notice of non-renewal at least 30 days before expiry — or 90 days in the case of Tero — the Subscription renews automatically for successive periods equal to the original term.

Termination for cause

Either party may terminate this Agreement by giving 30 days’ written notice if the other party commits a material breach and fails to remedy it within that notice period. Either party may also terminate immediately if the other party becomes insolvent, enters administration or liquidation, or ceases to carry on business. Where the Customer terminates under this clause due to Tero’s material breach, Tero shall refund any fees paid in advance for the period between the termination date and the end of the contracted term.

Effect of termination

On termination or expiry of the Subscription: (a) the Customer’s right to access the Platform ceases immediately; (b) all outstanding fees become due and payable; and (c) each party shall promptly return or, on written instruction, destroy the other party’s Confidential Information. Within 30 days of termination, the Customer may request an export of any Legal Content stored on the Platform in a standard machine-readable format. Following that 30-day period, unless restricted by applicable law, Tero shall securely delete all remaining Legal Content in accordance with industry-standard data destruction practices. On written request, Tero will provide the Customer with a written confirmation that deletion has been completed.

Suspension

Tero may suspend access to the Platform, following written notice, where: (a) the Customer is in material breach of these Terms; (b) Tero is required to do so by law or court order; or (c) continued operation poses an immediate and material security risk. Tero will provide advance written notice of any suspension except where doing so is not reasonably practicable in the circumstances.

Warranties and Disclaimer

We warrant the platform works as described with reasonable care and skill. Beyond that, it is provided as-is — we do not guarantee it will meet every specific need.

We warrant the platform works with reasonable care and skill. Beyond that, it is provided as-is — we cannot guarantee it will be perfect.

Tero’s warranties

Tero warrants that: (a) the Platform will be provided with reasonable skill and care and will materially conform to any specifications provided by Tero; (b) it has the rights necessary to grant the licences set out in these Terms; (c) it will maintain reasonable security measures throughout the term; and (d) to Tero’s knowledge, the Services do not infringe any third-party intellectual property rights.

Disclaimer

Except as expressly stated in these Terms, the Platform is provided “as is” and “as available”. To the fullest extent permitted by applicable law, Tero disclaims all other warranties, whether express, implied, or statutory, including any implied warranties of merchantability, fitness for a particular purpose, or non-infringement. Tero does not warrant that the Platform will be uninterrupted, error-free, or free from security vulnerabilities.

Limitation of Liability

Most liability is capped at 12 months of fees or €250,000 (whichever is higher). Higher caps apply for data and confidentiality breaches. Fraud and death or personal injury are uncapped.

Liability for most claims is capped at 12 months of fees or €250,000. For data and confidentiality breaches the cap doubles. Some liability cannot be limited by law.

Exclusion of consequential loss

To the fullest extent permitted by applicable law, neither party shall be liable to the other for any indirect, incidental, special, consequential, or punitive loss or damages, including loss of profits, loss of revenue, loss of data, or loss of business opportunity, even if that party has been advised of the possibility of such loss.

Standard aggregate cap

Subject to clause 11.3 and 11.4, each party’s total aggregate liability to the other under or in connection with this Agreement shall not exceed the greater of: (a) the total Subscription fees paid or payable by the Customer in the 12 months preceding the event giving rise to the claim; and (b) €250,000.

Enhanced cap for data and confidentiality breaches

The cap in clause 11.2 does not apply to claims arising from a breach of the confidentiality obligations in Section 8 or a breach of the Data Processing Agreement (“Enhanced Claims”). For Enhanced Claims, each party’s total aggregate liability shall not exceed the greater of: (a) two times the total Subscription fees paid or payable by the Customer in the 12 months preceding the event giving rise to the claim; and (b) €500,000.

Uncapped liability

Nothing in these Terms excludes or limits liability for: (a) death or personal injury caused by negligence; (b) fraud or fraudulent misrepresentation; (c) the Customer’s payment obligations; or (d) any other liability that cannot be excluded or limited under applicable Danish law.

Claims notification

Any claim for damages must be notified in writing to the other party within 24 months of the date the claiming party became aware, or ought reasonably to have become aware, of the circumstances giving rise to the claim; except that claims arising from a breach of Sections 6, 7, or 8 must be notified within 36 months of the date of awareness. Claims notified after the applicable period will not be valid. Time does not begin to run in respect of a claim that the claiming party could not reasonably have discovered through the exercise of reasonable diligence.

Indemnification

We protect you against IP claims arising from our platform. You protect us if your use of the platform causes a third-party claim against us.

We protect you against third-party IP claims arising from using our platform as intended. You protect us against claims arising from content you upload.

By Tero

Tero will defend the Customer against any third-party claim alleging that the Customer’s use of the Services in accordance with this Agreement infringes a third party’s intellectual property rights, and will pay any damages and reasonable legal costs finally awarded against the Customer in connection with such a claim. If such a claim arises or appears likely, Tero may at its option: (a) modify the Services to remove the alleged infringement; (b) obtain a right for the Customer to continue using the Services; or, if neither option is commercially reasonable, (c) terminate the Agreement and refund any prepaid unused fees. Tero’s obligation under this clause does not apply to claims attributable to Input, to Output generated from Input that violates these Terms, or to modifications made to the Services by anyone other than Tero.

By the Customer

The Customer will defend Tero against any third-party claim arising from Input or Output generated from Input that violates these Terms or that the Customer knew was unlawful or in material breach of these Terms, and will pay any damages and reasonable legal costs finally awarded against Tero in connection with such a claim.

Indemnification process

The indemnification obligations in clauses 12.1 and 12.2 are conditional on the party seeking indemnification: (a) promptly notifying the indemnifying party in writing of the claim; (b) giving the indemnifying party sole control of the defence and any settlement negotiations, provided that no settlement may be agreed that imposes obligations or liability on the indemnified party without its prior written consent; and (c) providing reasonable cooperation at the indemnifying party’s cost.

Changes to the Service and Terms

We can update the platform and these terms with advance notice. If a material change harms you, you may terminate without penalty.

We can update the platform and these terms with advance notice. If an update materially harms you, you can exit without penalty.

Service changes

Tero may modify, update, or discontinue features of the Platform. Tero will provide reasonable advance written notice of any material change that is likely to have an adverse effect on the Customer’s use of the Services.

Changes to Terms

Tero may update these Terms by notifying the Customer by email or in-platform notice at least 30 days before the updated Terms take effect. Continued use of the Platform after the effective date constitutes acceptance of the updated Terms. If the Customer reasonably considers an update to be materially adverse, it may raise this in writing within 30 days of notification. If Tero is unable to resolve the concern within a further 30 days, the Customer may terminate the Agreement on 15 days’ written notice without penalty, and Tero will refund any prepaid unused fees. Tero will not amend its obligations regarding Confidential Information, Legal Content, or security without the Customer’s prior written consent.

General

Danish law governs this agreement. Disputes go to Aarhus City Court after a 30-day escalation attempt. Standard boilerplate applies.

Governing law is Denmark. Disputes go to Aarhus City Court after a 30-day escalation period. Standard boilerplate provisions apply.

Governing law and jurisdiction

This Agreement is governed by the laws of Denmark. Any disputes arising under or in connection with this Agreement that cannot be resolved by good-faith negotiation between the parties will be subject to the exclusive jurisdiction of Retten i Aarhus (Aarhus City Court) as court of first instance.

Entire agreement

This Agreement, together with the applicable Order Form, DPA, and Privacy Policy, constitutes the entire agreement between the parties in respect of the Platform and supersedes all prior agreements, representations, and understandings relating to its subject matter.

Severability

If any provision of this Agreement is found to be invalid or unenforceable, it shall be modified to the minimum extent necessary to make it enforceable. The remaining provisions shall continue in full force and effect.

Waiver

Failure by either party to exercise or enforce any right under this Agreement does not constitute a waiver of that right. Any waiver must be made in writing to be effective.

Assignment

The Customer may not assign or transfer any rights or obligations under this Agreement without Tero’s prior written consent. Either party may assign this Agreement without consent in connection with a merger, acquisition, or sale of all or substantially all of its assets, provided the assignee assumes all obligations under the Agreement.

Subcontractors

Tero may engage subcontractors to assist in delivering the Services, subject to the confidentiality and data protection obligations in this Agreement. Tero remains solely responsible to the Customer for the performance of the Services regardless of any subcontracting arrangement.

No partnership

This Agreement does not create a partnership, joint venture, or agency relationship between the parties. Neither party has authority to bind the other or incur obligations on the other’s behalf.

Force majeure

Neither party will be liable for delays or failures in performance resulting from causes beyond their reasonable control, including natural disasters, governmental actions, acts of war, widespread internet outages, or failure of third-party infrastructure providers. Payment obligations are not relieved by force majeure events. If a force majeure event prevents material performance for more than 30 consecutive days, either party may terminate the Agreement on written notice without liability.

Notices

Notices under this Agreement must be in writing. Notices of termination should be sent to legal@tero.legal and to the Customer’s designated contact as specified in the Order Form. All other notices may be sent by email to the parties’ respective contact persons and will be deemed received on the day of sending.

Dispute escalation

Before commencing any court proceedings under clause 14.1, the parties shall first attempt to resolve any dispute through good-faith negotiations at senior management level for a period of 30 days following written notice from the claiming party (“Escalation Notice”). If the dispute is not resolved within that period, either party may refer the matter to non-binding mediation administered by the Danish Mediation Institute (Mediationsinstituttet) before commencing formal proceedings. The commencement of escalation and mediation proceedings does not prevent either party from seeking urgent interim or injunctive relief from a competent court where necessary to prevent irreparable harm.
