Terms of Service

Effective date: 12 May 2026

These Terms of Service (“Terms”) govern your use of the Seneca service operated by Headers s.r.o., a company registered in the Czech Republic, ID No. 06434967, with its registered office at Radniční 133/1, 370 01 České Budějovice 1 (“Headers”, “we”, “us”). By creating an account or otherwise using the Service, you agree to these Terms.

If you do not agree, do not use the Service.

1. Definitions

• Service - the Seneca product available at https://senecabot.com, including the web application, agents, APIs, and related software.
• Customer - the person or organization that creates an account and uses the Service.
• End User - a third party who interacts with a Seneca-powered chat or agent operated by a Customer.
• Customer Content - any documents, URLs, snippets, conversations or other data submitted to the Service by or for a Customer.
• Output - responses generated by the Service in reply to End User queries based on Customer Content.

2. Eligibility and account

You must be at least 16 years old to use the Service. By creating an account you confirm that the information you provide is accurate and that you are authorised to bind any organization on whose behalf you act.

You are responsible for keeping your account credentials secure and for all activity that occurs under your account.

3. Service description

Seneca is an AI assistant that answers questions based on documents you upload or websites you connect. Each answer is accompanied by a citation to the source. Seneca is informational only - answers may be incomplete or inaccurate, and you must not rely on them as professional, legal, medical or financial advice.

We continuously improve the Service. Features may be added, changed, or removed. We will give reasonable notice for material changes that affect existing functionality.

4. Beta status and pricing

The Service is currently provided free of charge during beta. The beta period runs until 31 August 2026. From 1 September 2026 we are introducing paid plans.

We do not guarantee that the Service will remain free for beta Customers after 31 August 2026. If you do not switch to a paid plan, your access to the Service may be suspended or terminated. We will, however, keep prices at a reasonable level and will publish them in advance on our Pricing page.

5. Customer Content - ownership and licence

Customer Content remains your property. You retain all intellectual property rights in Customer Content and Output.

You grant us a worldwide, non-exclusive, royalty-free licence to host, copy, transmit, display, and process Customer Content solely to operate and provide the Service to you. This licence ends when Customer Content is deleted from the Service, subject to Section 9 (Data Retention).

We do not use Customer Content to train any AI model. Customer Content is not shared with other Customers and is not used to develop or improve any model, except for aggregated, non-personal operational metrics (such as response time, error rates).

6. Acceptable use

You agree not to use the Service to:

• upload or process content you do not have the right to use;
• upload illegal content, malware, or content that infringes third-party rights;
• circumvent, disable, or interfere with security or rate-limiting features;
• attempt to extract the underlying AI model, prompts, or other Customer Content;
• use the Service for spam, harassment, or unlawful surveillance;
• generate content that is defamatory, obscene, or otherwise harmful in violation of applicable law.

We may suspend or terminate accounts that breach this section. Where we host content provided by you that we are required by law to remove or restrict (for example, under the Digital Services Act), we will act in line with the procedures published on our website and notify you where legally permitted.

7. AI Output - no warranty

The Service uses large language models to generate Output. Despite our citation-based approach, Output may contain errors, omissions, or content not actually present in your sources. You are responsible for reviewing Output before relying on it. We make no warranty that Output will be accurate, complete, current, or fit for any particular purpose.

You are responsible for ensuring that any Output you publish or rely upon complies with applicable law and does not infringe third-party rights.

8. Subprocessors and privacy

We process personal data in accordance with our Privacy Policy. The list of subprocessors and the regions in which they operate is published in the Privacy Policy.

We do not sell or rent personal data.

9. Data retention and export

While your account is active, you can export Customer Content from the Service at any time using available export tools.

If you delete your account, we keep Customer Content for 30 days to allow recovery in case of accidental deletion. After 30 days, Customer Content is permanently deleted from active systems.

10. Service availability

We provide the Service on a best-effort basis. We do not commit to a specific uptime, response time, or service level. Maintenance, downtime and changes may occur, and we will give reasonable advance notice for planned maintenance where practicable.

11. Suspension and termination

You may stop using the Service and delete your account at any time.

We may suspend or terminate your access immediately if you breach these Terms, if continued provision of the Service to you would expose us to legal risk, or if required by law. Where reasonable, we will notify you in advance and give you an opportunity to cure the breach.

Either party may terminate the agreement for convenience with 30 days’ written notice.

Sections that by their nature should survive termination (including 5, 7, 12, 13, 15) survive termination.

12. Disclaimers

Except as expressly stated in these Terms, the Service is provided “as is” and “as available”, without any warranty of any kind, whether express or implied, including warranties of merchantability, fitness for a particular purpose, or non-infringement. We do not warrant that the Service will be uninterrupted, error-free, or secure, or that Output will be accurate.

13. Limitation of liability

To the maximum extent permitted by law:

• neither party is liable for indirect, incidental, consequential, special or punitive damages, or for loss of profits, revenue, data or business;
• our total aggregate liability arising out of or related to the Service is capped at the greater of (a) the fees paid by you for the Service in the 12 months preceding the event giving rise to the claim, or (b) EUR 100.

Nothing in these Terms limits or excludes liability that cannot be limited or excluded under applicable law (including liability for gross negligence or willful misconduct).

14. Indemnification

You will defend and indemnify Headers against third-party claims arising from your Customer Content, your breach of these Terms, or your unlawful use of the Service. We will defend and indemnify you against third-party claims that the Service, as provided by us, infringes third-party intellectual property rights, except where the claim arises from your Customer Content or use of the Service in breach of these Terms.

The indemnified party must promptly notify the indemnifier of the claim and reasonably cooperate in its defence.

15. Governing law and disputes

These Terms are governed by the laws of the Czech Republic, excluding its conflict-of-laws rules. Any dispute arising out of or in connection with these Terms shall be resolved by the courts of the Czech Republic having jurisdiction.

If you are a consumer resident in the European Union, mandatory consumer protection rules of your country of residence continue to apply.

16. Changes to these Terms

We may update these Terms from time to time. We will post the updated version on our website with a new effective date. For material changes, we will notify Customers by email at least 30 days in advance. Your continued use of the Service after the effective date constitutes acceptance of the updated Terms.

17. Miscellaneous

• Entire agreement. These Terms (together with the Privacy Policy and any plan-specific terms) form the entire agreement between you and Headers regarding the Service.
• Severability. If any provision is held unenforceable, the rest of the Terms remain in effect.
• No waiver. Failure to enforce a provision is not a waiver of that provision.
• Assignment. You may not assign these Terms without our prior written consent. We may assign them to an affiliate or to a successor in connection with a corporate transaction.
• Force majeure. Neither party is liable for failure to perform due to events beyond reasonable control (acts of God, war, internet outage, change of law).
• Notices. Notices to you may be sent to the email address associated with your account. Notices to Headers must be sent to legal@senecabot.com.
