Terms of Service

Effective date: 2026-07-22

These Terms of Service ("Terms") govern your use of the Celeus service ("the Service"), operated by Celeus LLC ("we", "us"). By creating an account, signing in, or using the Service, you agree to these Terms.

1. What the Service is - and what it is not

The Service is a statistical analysis tool for research: it profiles datasets, recommends and runs established statistical methods with a deterministic computation engine, and produces reproducible, study-level output (results, figures, tables, and manuscript-style text).

The Service is not a medical device, not clinical decision support, and not a source of medical advice. It analyzes data at the study level and never produces patient-specific diagnostic or treatment recommendations. Output is intended for qualified researchers who remain responsible for verifying every statistical result before relying on it or publishing it.

An artificial-intelligence assistant is part of the Service. It recommends methods, explains results, and drafts text - but it never computes statistics and never receives your data (see the Privacy Policy). All numbers come from the deterministic engine.

2. Your account and workspace

Accounts are personal. A workspace is the unit of collaboration, billing, and data isolation; the workspace administrator controls membership, plan, and data retention settings. You are responsible for actions taken under your account. Do not share credentials; invite collaborators instead - each member gets their own identity, and shared usage draws on the workspace's allowance either way.

3. Acceptable use

You agree to:

• upload only data you have the legal right to process for research;
• de-identify data before upload wherever possible - the Service provides de-identification tooling, PHI screening, and column controls for this purpose. Do not upload directly identifying information (names, addresses, identification numbers, or free-text fields containing them);
• comply with the ethical and regulatory requirements that apply to your research (IRB/ethics approvals, data-use agreements, and applicable law);
• not attempt to re-identify individuals from any data or output;
• not probe, disable, or circumvent the Service's security or the AI assistant's safeguards, and not use the Service to build a competing statistical inference dataset by systematic extraction.

We may suspend accounts that violate these terms, with notice where practicable.

4. Your data and your results

You retain all rights to the datasets you upload and to the analytical output the Service produces from them (results, figures, reproducible packages, and drafted text). We claim no ownership and use your data only to operate the Service for you, as described in the Privacy Policy. You may delete runs, datasets, your account, or your entire workspace at any time; deletion is permanent (see the Privacy Policy for what minimal integrity records remain).

5. Plans, billing, and top-up packs

Paid plans are workspace subscriptions with a monthly included usage allowance, billed through Stripe. Additional usage is available only through explicit, one-time prepaid top-up packs - the Service never bills usage-based overage automatically. Usage and remaining balances are always visible in the billing panel. Subscription changes and cancellation are self-service; cancellation takes effect at the end of the paid period. Prices and allowances may change with notice; changes never apply retroactively to an already-paid period.

6. Availability and beta status

The Service is currently offered in an invite-only beta. We aim for high availability but provide the Service "as is" and "as available", without warranty of uninterrupted operation. We may modify features with reasonable notice. Your statistical outputs are packaged for download precisely so that your results remain reproducible outside the Service.

7. Limitation of liability

To the maximum extent permitted by law: the Service is provided without warranties of any kind, express or implied, including fitness for a particular purpose; we are not liable for indirect, incidental, or consequential damages, or for decisions made in reliance on statistical output that you did not verify; and our total aggregate liability is limited to the amounts you paid for the Service in the twelve months preceding the claim. Nothing in these Terms excludes liability that cannot lawfully be excluded.

8. Termination

You may stop using the Service and erase your workspace at any time. We may terminate accounts for material breach of these Terms, with notice where practicable, and will provide a reasonable window to export your data except where legally prevented.

9. Changes to these Terms

We may update these Terms. Material changes will be announced in the Service or by email with reasonable advance notice. Continued use after the effective date of a change constitutes acceptance.

10. Governing law and contact

These Terms are governed by the laws of New Jersey. Questions: legal@celeus.ai.
