Privacy & data storage

We designed LetDraw to respect your privacy. Where your drawings live depends on whether you are signed in.

Guest use (not signed in): everything stays on your device

When you use LetDraw without signing in, your drawings never leave your device. Your scene is kept only in your browser (local storage); nothing is sent to our servers.

• If you do not want anything stored, or seen by us or anyone else, use guest mode (without signing in).
• The trade-off: no cross-device sync, no cloud backup, and no collaboration; if you clear your browser data, the drawing is lost.

When you sign in: stored in the cloud

When you sign in, your drawings are stored on our servers (a database hosted on Supabase) so they sync across your devices and are not lost.

• Only the people you grant access can see them. Access is enforced by row-level security (RLS) through workspace membership and folder access settings (Public / Team-only / Private); other users cannot reach your data.
• To provide the service (backups, debugging, abuse prevention) we, as the operator, may have technical access to the data. Document content is currently not end-to-end encrypted at rest. If you do not want that, use guest mode.

Share links are end-to-end encrypted

When you share a drawing via a link (“snapshot”), the content is end-to-end encrypted: the decryption key lives in the link’s # (fragment) and is never sent to the server. So the share server only holds the encrypted data and cannot read the content; only someone holding the link can open it.

Exporting and deleting your data

• Export: Settings → Profile → “Export your data” lets you download all your data as a single JSON file (KVKK Article 11 / GDPR Articles 15, 20).
• Delete: Settings → Profile → “Delete account” permanently removes your account and all data you own (workspaces, folders, documents, comments).

Analytics

Anonymous product-usage analytics runs only when the operator has configured it, respects your browser’s “Do Not Track” signal, and can be turned off in Settings → Preferences → Privacy. Drawing content is not sent to analytics.

Third parties

Drawing content only goes to our database/hosting provider (Supabase). Drawing content is not sent to analytics or error-tracking services.

In short

If you do not want anything stored, use guest mode (local). If you want sync/collaboration, sign in; your data is kept in the cloud, only the people you allow can see it, and you can export and delete it whenever you want. Share links are end-to-end encrypted.
