Privacy Policy

SinStories is an adult (18+) AI service that generates fictional stories. This Privacy Policy explains, in plain language, what personal data we collect, how and why we use it, who we share it with, and the rights you have. It applies to sinstories.app and the SinStories app.

Information you give us. To create an account you provide your email address; we sign you in with a one-time magic link, so we never ask for or store a password. When you generate stories you provide prompts and choices, and we store those prompts and the resulting stories so they appear in your library.

Information we collect automatically. We record account and usage data needed to run the service, such as your remaining credits, plan and activity. For security and analytics we process technical data — your IP address (kept only as a one-way hash), the approximate country and city it maps to, and general device and browser information.

Payments. If you buy a paid plan, the payment is processed by our payment provider, Stripe, under its own privacy policy. Stripe handles your card details directly; we receive only limited information such as your subscription status and the last four digits — we never see or store full card numbers.

How we use your data. We use it to provide the service (generate and save your stories, run your account and credits), process payments and manage subscriptions, keep the service safe (moderation, preventing abuse and fraud), understand and improve the product, and send essential service messages. We do not use your prompts or stories to train third-party AI models.

Legal bases (EEA/UK). Where GDPR applies, we rely on performance of our contract with you, your consent (for cookie-based analytics and any marketing), our legitimate interests (security, abuse prevention and improving the service), and compliance with legal obligations.

Cookies and analytics. We use essential cookies needed to sign you in, keep your session and run the site (including our A/B test of the landing). Analytics that rely on non-essential cookies run only after you consent, and you can withdraw consent at any time.

Sharing. We never sell your personal data and we don't share it with third parties for their own marketing. We share limited data only with service providers acting on our behalf (such as hosting, email delivery, payment processing and analytics) and where the law requires it, such as a valid legal request.

Retention. We keep your account data and content for as long as your account is active. You can delete your account and its data at any time by writing to support@sinstories.app; we delete it promptly, except for the minimum records we are legally required to keep, such as billing records. Detailed analytics events are kept for no more than 100 days and are then reduced to aggregate statistics that are no longer tied to an individual visitor; stories generated on the landing page without an account have their text deleted after about five weeks.

Security. We protect your data with encryption in transit, hashed IP addresses and access controls. No online service can be completely secure, so we also encourage you to keep access to your email secure and your library off shared devices.

Your rights. Depending on where you live, you may have the right to access, correct, delete, export or restrict the processing of your data, to object to certain processing and to withdraw consent. California residents have the right to know about and delete their personal information and not to be discriminated against for exercising these rights; note that we do not sell personal information. To exercise any right, email support@sinstories.app.

Children. SinStories is strictly for adults. It is not directed to anyone under 18 and we do not knowingly collect data from minors. If you believe a minor has used the service, contact us and we will remove the account.

Changes and contact. We may process data in countries other than your own, using appropriate safeguards. We may also update this policy; the date above shows the latest version and we will flag material changes. For any privacy question or request, contact support@sinstories.app.
