Privacy

The short version

Cicatriz does not collect, store, or share your personal data. We have no accounts, no database, and no analytics tied to individuals. Your birth data never touches our servers in a readable form.

If you close the result page and discard the URL, your data is gone. There is nothing to delete, no account to deactivate, and no email to unsubscribe from.

Your birth data

When you submit the form, your birth details (name, date, time, city, coordinates, timezone) are encrypted with AES-256-GCM on our server and returned to you as an opaque token embedded in your subscribe URL. We do not log or retain this data.

Each time your calendar app fetches the feed, the token is decrypted in memory, the calendar is computed, and the response is sent. Nothing is written to disk or stored between requests.

The subscribe URL is yours to control. Share it only with people you trust, since it encodes your birth details. Anyone with the URL can generate your calendar.

Third-party services

We use Vercel to host the application. Vercel may log standard HTTP request metadata (IP address, user agent, timestamp) as part of normal infrastructure operation. See vercel.com/legal/privacy-policy for details.

City search uses the Nominatim API (OpenStreetMap), which receives your typed city query. No birth data is sent to Nominatim. We also use Vercel Analytics to count aggregate page views and custom events (form submissions, calendar subscriptions). No personal identifiers are collected.
