Terms of Service

Last updated: 28 May 2026

These Terms govern your use of CERULEON ("the Service"), operated at ceruleon.app. By creating an account or accessing the Service, you agree to these Terms. If you disagree, do not use the Service.

1. The Service

CERULEON helps medical-device teams build literature-search strategies, screen results, and assemble evidence summaries for clinical evaluation. The Service includes a search interface against public bibliographic databases (PubMed E-utilities, iCite, Unpaywall), AI-assisted query optimisation and screening, and exportable reports.

2. Accounts

• You must be at least 16 years old and able to enter a binding contract.
• You are responsible for keeping your credentials confidential and for all activity under your account.
• Notify us promptly at contact@ceruleon.app of any suspected unauthorised use.

3. Acceptable use

You agree not to:

• Reverse-engineer, scrape, or attempt to extract source code or training data.
• Use the Service to process personal data of patients without a lawful basis under GDPR.
• Bypass rate limits, share accounts across multiple users, or resell access without a written agreement.
• Upload content you do not have the right to use (copyrighted full-text PDFs you do not own a licence to, confidential third-party material, etc.).
• Use the Service for any unlawful, defamatory, or harmful purpose.

4. Subscriptions and billing

• Paid plans are billed monthly or annually in advance through Stripe. Prices and features are listed at ceruleon.app/#lpPricing.
• Subscriptions renew automatically at the end of each billing period unless cancelled before renewal.
• You may cancel at any time from your account settings; access continues until the end of the paid period.
• EU consumers have a 14-day right of withdrawal (Consumer Rights Directive 2011/83/EU). By starting active use of the Service, you expressly request immediate performance and waive this right for any portion already consumed.
• VAT is added where required by your local jurisdiction.

5. AI features and accuracy

AI assistance (query optimisation, screening proposals, synthesis drafts) is generated by third-party large-language-model providers. AI outputs may be incomplete, biased, or wrong. You must independently verify any output before relying on it for a regulatory submission, clinical decision, or publication. CERULEON makes no representation that AI outputs are fit for any particular regulatory purpose.

6. Intellectual property

• You retain all rights to data, files, and outputs you create using the Service.
• We retain all rights to the Service software, design, and branding.
• You grant us a limited licence to process your content solely to operate the Service and to compute anonymised, aggregated metrics for product improvement (no individual project content is shared with third parties).

7. Confidentiality

Project data you enter is treated as confidential. We do not disclose it except: (a) to processors listed in our Privacy Policy under DPA, (b) where required by law, or (c) with your written consent.

8. Service availability

We aim for high availability but do not guarantee uninterrupted access. Scheduled maintenance is announced in advance where possible. We are not liable for downtime, third-party API outages (PubMed, Stripe, AI providers), or your own internet connectivity.

9. Disclaimers

To the maximum extent permitted by law, the Service is provided "as is" and "as available". We disclaim all implied warranties of merchantability, fitness for a particular purpose, and non-infringement. This does not exclude liability for gross negligence, wilful misconduct, or harm to life and limb where such exclusion is prohibited.

10. Limitation of liability

To the extent permitted by law, our aggregate liability arising from or related to the Service in any 12-month period is limited to the amount you paid us during that period. We are not liable for indirect, incidental, consequential, or punitive damages, including lost profits, lost data, or regulatory rejection of work product.

11. Termination

You may close your account at any time from settings or by writing to contact@ceruleon.app. We may suspend or terminate accounts that breach these Terms, with or without notice depending on severity. On termination you retain a 30-day window to export your data; thereafter it is deleted as described in the Privacy Policy.

12. Changes

We may update these Terms. Material changes are notified in-app and by email at least 30 days before they take effect. Continued use after the effective date constitutes acceptance.

13. Governing law and venue

These Terms are governed by the law of the European Union member state where CERULEON is established, without prejudice to mandatory consumer-protection rules of your country of residence. Disputes are submitted to the competent courts of that jurisdiction, save where mandatory law provides otherwise.
