Terms of Service

Last updated: 20 March 2026

These Terms of Service ("Terms") govern Your access to and use of the Artanis platform and related services. By accessing or using the Service, You agree to be bound by these Terms. If You are entering into these Terms on behalf of an organisation, You represent that You have the authority to bind that organisation.

1. Definitions

• "Artanis", "We", "Us", or "Our" means Artanis Ltd, a company registered in England and Wales (company number pending), with its registered office at 71-75 Shelton Street, London WC2H 9JQ.
• "Service" means the Artanis platform, including the web application at app.artanis.ai, all associated APIs, documentation, and any related services We provide.
• "Customer", "You", or "Your" means the individual or organisation that accesses or uses the Service.
• "Customer Data" means all data, content, and information submitted to the Service by or on behalf of the Customer, including but not limited to prompts, inputs, outputs, labels, evaluation data, configurations, and any results or reports generated from such data.
• "Authorised Users" means individuals whom the Customer permits to access and use the Service under the Customer's account.
• "Subscription" means the Customer's paid or free-tier access to the Service for a defined period.
• "DPA" means the Data Processing Agreement available at artanis.ai/dpa, which forms part of these Terms.

2. The Service

Artanis provides a software-as-a-service platform for measuring and improving AI accuracy in production. The Service enables Customers to label data, build evaluations, and improve prompts using Artanis's proprietary AI technology.

We will use commercially reasonable efforts to make the Service available in accordance with any service-level commitments described in Your Subscription plan. We may update or modify the Service from time to time, provided that such changes do not materially reduce the core functionality available under Your Subscription.

3. Account Registration and Access

To use the Service, You must create an account using Google OAuth. You are responsible for maintaining the security of Your account credentials and for all activity that occurs under Your account. You must promptly notify Us at team@artanis.ai if You become aware of any unauthorised use of Your account.

You are responsible for ensuring that Your Authorised Users comply with these Terms. Any breach of these Terms by an Authorised User shall be deemed a breach by the Customer.

4. Subscription and Fees

Access to the Service is provided under a Subscription, which may be a free tier or a paid plan as described on Our website or in a separate order form. For paid Subscriptions:

• Fees are as set out in Your Subscription plan or order form and are exclusive of applicable taxes.
• Subscriptions renew automatically at the end of each billing period unless cancelled with at least 30 days' written notice before the renewal date.
• We may change Our fees upon at least 30 days' notice before the start of a new billing period. Continued use of the Service after a fee change constitutes acceptance of the new fees.
• All fees are non-refundable except as expressly set out in these Terms or as required by applicable law.

5. Customer Data and Intellectual Property

5.1 Customer Owns All Customer Data

You retain all right, title, and interest (including all intellectual property rights) in and to Your Customer Data. This includes, without limitation:

• Your prompts, inputs, and configurations;
• Your AI outputs and responses;
• Your labels, annotations, and evaluation criteria;
• All evaluation results, reports, and analytics derived from Your Customer Data; and
• Any improved or modified prompts, whether created by You or generated with the assistance of the Service.

For the avoidance of doubt, Your prompts are Your intellectual property. Where the Service assists You in improving or rewriting prompts, the resulting prompts belong to You.

5.2 Limited Licence to Artanis

You grant Artanis a limited, non-exclusive, royalty-free licence to access, use, and process Customer Data solely as necessary to provide, maintain, and improve the Service for You. This licence terminates upon deletion of Your Customer Data or termination of Your account.

5.3 No Training on Customer Data

We will not use Customer Data to train, fine-tune, or improve any machine learning models (whether Our own or third-party models) unless You provide explicit, prior written consent. Aggregated and anonymised usage statistics (such as feature adoption rates) that cannot be used to identify You or reconstruct Your Customer Data are not considered Customer Data for the purposes of this clause.

5.4 Data Export

You may export Your Customer Data from the Service at any time during Your Subscription in a standard, machine-readable format. Upon written request, We will assist You in exporting Your data at no additional charge.

5.5 Artanis Intellectual Property

Artanis retains all right, title, and interest in and to the Service, including all underlying technology, AI models, evaluation algorithms, software, documentation, and any improvements or modifications thereto. Nothing in these Terms transfers any ownership of Artanis's intellectual property to You. Your right to use the Service is limited to the licence granted under Your Subscription.

6. Acceptable Use

You agree not to:

• Use the Service in violation of any applicable law or regulation;
• Reverse engineer, decompile, or disassemble any part of the Service;
• Attempt to gain unauthorised access to the Service or its related systems;
• Use the Service to store or transmit malicious code;
• Interfere with or disrupt the integrity or performance of the Service;
• Resell, sublicense, or make the Service available to third parties except to Your Authorised Users; or
• Use the Service to develop a competing product or service.

7. Confidentiality

Each party agrees to keep confidential all non-public information disclosed by the other party that is designated as confidential or that reasonably should be understood to be confidential ("Confidential Information"). Neither party will use the other party's Confidential Information except as necessary to perform its obligations or exercise its rights under these Terms. Customer Data is deemed the Customer's Confidential Information.

Confidential Information does not include information that: (a) is or becomes publicly available through no fault of the receiving party; (b) was already known to the receiving party without restriction; (c) is independently developed by the receiving party; or (d) is rightfully received from a third party without restriction.

8. Data Protection

We process personal data in accordance with Our Privacy Policy and the UK General Data Protection Regulation ("UK GDPR") and the Data Protection Act 2018.

To the extent that Artanis processes personal data on Your behalf as a data processor, the terms of Our Data Processing Agreement apply and are incorporated into these Terms by reference. The DPA sets out the scope, nature, and purpose of processing, as well as the obligations and rights of both parties.

9. Warranties and Disclaimers

Each party warrants that it has the legal power and authority to enter into these Terms. Artanis warrants that the Service will perform materially in accordance with its documentation.

Except as expressly set out in these Terms, the Service is provided "as is" and "as available". To the maximum extent permitted by applicable law, Artanis disclaims all other warranties, whether express, implied, or statutory, including implied warranties of merchantability, fitness for a particular purpose, and non-infringement.

Artanis does not warrant that the Service will be uninterrupted, error-free, or that all defects will be corrected. The Service's AI-powered features provide suggestions and assistance; You are responsible for reviewing and validating any outputs before relying on them.

10. Limitation of Liability

To the maximum extent permitted by applicable law:

• Exclusion of indirect damages. Neither party shall be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits, revenue, data, or business opportunity, however caused and under any theory of liability.
• Liability cap. Each party's total aggregate liability under or in connection with these Terms shall not exceed the total fees paid or payable by the Customer to Artanis in the twelve (12) months immediately preceding the event giving rise to the claim.
• Exceptions. The limitations in this section do not apply to: (a) either party's indemnification obligations; (b) a party's breach of its confidentiality obligations; (c) Artanis's obligations under the DPA with respect to personal data breaches; or (d) liability that cannot be excluded or limited under applicable law, including liability for fraud or death or personal injury caused by negligence.

11. Indemnification

Artanis will defend, indemnify, and hold You harmless against any third-party claim that the Service infringes the intellectual property rights of that third party, and will pay any resulting damages finally awarded or settlement amounts, provided that You give Us prompt notice, reasonable cooperation, and sole control of the defence.

You will defend, indemnify, and hold Artanis harmless against any third-party claim arising from: (a) Your Customer Data; (b) Your use of the Service in violation of these Terms; or (c) Your breach of applicable law.

12. Term and Termination

These Terms commence when You first access or use the Service and continue for the duration of Your Subscription.

• Termination for convenience. Either party may terminate a paid Subscription by providing at least 30 days' written notice before the end of the then-current billing period.
• Termination for cause. Either party may terminate these Terms immediately upon written notice if the other party materially breaches these Terms and fails to cure such breach within 30 days of receiving written notice of the breach.
• Termination for insolvency. Either party may terminate these Terms immediately if the other party becomes insolvent, enters administration, or ceases to carry on business.

13. Effect of Termination

Upon termination or expiry of these Terms:

• Your right to access and use the Service will cease immediately.
• You will have 30 days from the date of termination to export Your Customer Data. We will provide reasonable assistance with data export upon request.
• After the 30-day export period, We will delete Your Customer Data in accordance with Our DPA, unless retention is required by applicable law.
• Sections that by their nature should survive termination will survive, including but not limited to: Intellectual Property, Confidentiality, Limitation of Liability, Indemnification, and Governing Law.

14. Modifications to These Terms

We may update these Terms from time to time. We will provide at least 30 days' notice of material changes by email or through the Service. Continued use of the Service after such changes take effect constitutes acceptance of the revised Terms. If You do not agree to the revised Terms, You may terminate Your Subscription before the changes take effect.

15. Governing Law and Jurisdiction

These Terms are governed by and construed in accordance with the laws of England and Wales. The parties submit to the exclusive jurisdiction of the courts of England and Wales for the resolution of any disputes arising out of or in connection with these Terms.

16. General Provisions

• Entire agreement. These Terms (together with the Privacy Policy and DPA) constitute the entire agreement between the parties with respect to the subject matter hereof and supersede all prior agreements, representations, and understandings.
• Severability. If any provision of these Terms is held to be invalid or unenforceable, the remaining provisions will remain in full force and effect.
• Waiver. No waiver of any term shall be deemed a further or continuing waiver of such term or any other term.
• Assignment. You may not assign these Terms without Our prior written consent. We may assign these Terms in connection with a merger, acquisition, or sale of all or substantially all of Our assets.
• Force majeure. Neither party shall be liable for any failure or delay in performing its obligations where such failure or delay results from circumstances beyond its reasonable control.
• Notices. Notices under these Terms must be in writing and sent to team@artanis.ai (for Artanis) or to the email address associated with Your account (for You).
