Sync and sign-in
Sync sends designs, progress, reviews and run summaries. The database region is Singapore. Sign-in uses a session cookie; the current authentication configuration also enables a short-lived session cache cookie. Preferences stay on your device.
Export or erase
Export your local backup from Settings. Let sync finish first to include cloud records. To delete your account and synced data, open Account, then Delete account. Reset local data separately in Settings; clear site data in your browser to remove offline copies.
