+### Security and privacy
+
+Reviewed before release; every fix below comes with a test.
+
+- Uploaded files are identified by their content, not by the type the browser declares. Only real images, audio, video, PDF, Word, text, GeoJSON and GPX files are accepted, and every file is served with `nosniff` and a sandboxed Content-Security-Policy.
+- Photos are re-encoded without their metadata (GPS location, device, date taken); the phone's rotation is applied to the pixels. Location data is also removed from phone videos.
+- Image addresses carry a short-lived, read-only media token instead of the account session.
+- Tree annotations are only readable by people who can open the tree.
+- Password attempts are limited per client and per tree. The API only trusts the address set by its own reverse proxy (`TRUST_PROXY`).
+- Changing a tree's sharing password closes every session opened with the old one, including those linked to an account.
+- Deleted or rejected media are erased from disk; a per-tree storage quota applies.
+- GEDCOM import and export are hardened against oversized or malformed files.
+- The web server sends HSTS and a Content-Security-Policy. Fonts are served by the app itself, with no call to Google.
+- Analytics (only when a PostHog key is set) never include the tree's address, and session recording is off.
+
 ### License
 
 - [PolyForm Noncommercial 1.0.0](LICENSE): free to read, modify and self-host for non-commercial use.
