+## Privacy and documentation
+
+- `PRIVACY.md` is the public privacy policy. Keep it consistent with actual app behavior and store
+  metadata; put detailed diagnostic endpoint inventories and encryption implementation details in
+  README instead of duplicating them in the policy.
+- Support emails, including sender addresses, messages and attachments, are retained until the
+  reported problem is fixed, then deleted. This is the developer's operational practice, not an
+  app-enforced retention timer. Uninstalling the app does not remove email or exported/shared copies.
+- Keep the privacy-policy link at the bottom of Settings, targeting the public policy on `main`,
+  with localized labels and an error message when no browser can open it.
+- Update current documentation while preserving historical changelogs. Review reports are dated
+  snapshots, not proof of current coverage or external store compliance; see
+  `docs/reviews/privacy-policy.md` for privacy follow-ups.
