Terms of Service & EULA
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
- The App offers an auto-renewing Pro subscription (weekly, monthly, 3-month, 6-month, or annual) and consumable credit packs, purchased through your Apple ID (App Store) or your Google account (Google Play), depending on where you installed the App.
- Auto-renewal: subscriptions renew automatically at the then-current price unless cancelled at least 24 hours before the period ends. Manage or cancel on iOS in Settings → [your name] → Subscriptions, or on Android in the Google Play app → profile icon → Payments & subscriptions → Subscriptions. Any free-trial unused portion is forfeited when you buy a subscription, where applicable.
- Credits are a limited, non-transferable, non-refundable license to use in-app features; they have no cash value and expire / are forfeited on account closure.
- Payment, refunds, and price are handled by the store you bought from — Apple or Google — under that store’s terms. We do not process or store your payment details.
- Exact product names, durations, and prices are shown on the paywall before purchase.
5. Acceptable use — zero tolerance for objectionable content
You agree not to use the App to create, request, solicit, or share content that:
- sexualizes minors in any way, or constitutes child sexual abuse material (CSAM) — we report such activity to authorities and ban the account immediately;
- harasses, threatens, defames, or promotes violence or self-harm against anyone;
- is unlawful, infringing, hateful, or that impersonates a real person without right;
- attempts to bypass our safety, moderation, or rate-limit systems.
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:
- Acknowledgement. These Terms are between you and us only, not with Apple. Apple is not responsible for the App or its content.
- Maintenance & support. We — not Apple — are solely responsible for providing any maintenance and support for the App. Apple has no obligation to furnish any maintenance or support services for it.
- Warranty. In the event of any failure of the App to conform to an applicable warranty, you may notify Apple and Apple will refund the purchase price of the App to you. To the maximum extent permitted by law, Apple has no other warranty obligation whatsoever with respect to the App; any other warranty claims are our responsibility, subject to Section 9.
- Product claims. We — not Apple — are responsible for addressing any claims by you or a third party relating to the App or your use of it, including product liability claims, claims that the App fails to conform to legal or regulatory requirements, and consumer-protection or similar claims.
- Intellectual property. In the event of a third-party claim that the App or your possession and use of it infringes that third party’s intellectual property rights, we — not Apple — are solely responsible for the investigation, defense, settlement and discharge of the claim.
- Legal compliance. You represent that you are not located in a country subject to a U.S. Government embargo or designated as a “terrorist supporting” country, and that you are not listed on any U.S. Government list of prohibited or restricted parties.
- Third-party beneficiary. Apple and Apple’s subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.
