Sirena

Terms of Service & EULA

Effective date: July 15, 2026 · Last updated: August 20, 2026

These Terms are a contract between you and Sirena (“we,” “us” — the operator of the Sirena app). By creating an account or using the Sirena app (the “App”) you agree to them. If you do not agree, do not use the App.

This App is licensed, not sold. Where you obtained the App through Apple’s App Store, Apple’s Licensed Application End User License Agreement (LEULA) also applies and, to the extent of any conflict on Apple-specific terms, governs; Apple is a third-party beneficiary of these Terms and may enforce them. Where you obtained the App through Google Play, the Google Play Terms of Service also apply to your download and purchases, and govern to the extent of any conflict on Google-specific terms.

1. Eligibility

Sirena is an 18+ app. You must be at least 18 years old (and the age of majority where required for the purchases you make). By using the App you confirm you meet this requirement. We may verify age and may suspend accounts that do not.

2. The service & your license

We grant you a personal, non-exclusive, non-transferable, revocable license to use the App for personal, non-commercial entertainment. You may not copy, reverse engineer, resell, scrape, or build a competing service from the App or its outputs, except where the law says we cannot restrict you.

3. AI characters — important

The characters are AI software, not real people, and their messages are generated automatically. Output may be inaccurate, fictional, or inappropriate despite our safeguards. Sirena does not provide medical, legal, financial, or psychological advice, and is not a crisis service. If you are in danger or considering self-harm, contact your local emergency number or a crisis hotline.

4. Subscriptions, credits & billing

5. Acceptable use — zero tolerance for objectionable content

You agree not to use the App to create, request, solicit, or share content that:

There is zero tolerance for objectionable content and abusive users. We use automated and human moderation, and we may remove content, suspend, or permanently ban accounts at our discretion.

6. Reporting & blocking

You can report a character or message from within the App, and we provide tools to limit content you do not want to see. We aim to review reports promptly (target: within 24 hours) and act on violations.

7. Your content

You retain ownership of content you submit. You grant us a worldwide, royalty-free license to host, process, transmit, display, and adapt it as needed to operate, secure, and moderate the App (including sending it to the AI providers in our Privacy Policy). You are responsible for the content you submit and confirm you have the rights to submit it.

8. Termination

You may stop using the App and delete your account at any time (Settings → Account → Delete Account). We may suspend or terminate access for violations of these Terms or to comply with law. Sections that by nature should survive (licenses you granted, disclaimers, liability limits, dispute terms) survive termination.

9. Disclaimers & limitation of liability

The App is provided “as is” without warranties of any kind, to the maximum extent permitted by law. To the maximum extent permitted by law, Sirena is not liable for indirect, incidental, or consequential damages, and our total liability is limited to the greater of the amount you paid us in the 12 months before the claim or USD 50. Some jurisdictions do not allow these limits, so they may not apply to you.

10. Indemnity

You agree to indemnify Sirena from claims arising out of your misuse of the App or violation of these Terms, to the extent permitted by law.

11. Governing law & disputes

These Terms are governed by the laws of the Socialist Republic of Vietnam, excluding conflict-of-laws rules. Before filing a claim, you agree to first contact us at support@sirenastories.com so we can try to resolve it informally. Nothing here removes mandatory consumer-protection rights you have where you live.

12. Changes

We may update these Terms. Material changes will be notified in-app. Continued use after changes means you accept them.

13. Apple App Store — additional terms

Where you obtained the App through Apple’s App Store, the following applies in addition to the LEULA incorporation above:
