Stored on this device only — there's no server, so this protects your budget from other people using the same browser, not from someone with access to this device's storage. Losing your password means losing access; use Export in Settings to keep a backup.
Your account and budget are saved to the cloud, so you can log in from any device. Your name, username, email and phone may also be copied to the app owner's records. Your password never is; it's stored only as a hash.
