Login privacy

Prinance is a private household finance tracker. Access is limited to the account approved by its operator.

When you choose Google sign-in, Google verifies your account and supplies its verified email address and account identifier. Prinance uses these only to check access to your existing workspace. The account identifier and login-session records are stored in a private Cloudflare Durable Object. Google access and refresh tokens are not retained.

Google handles your Google password and account security. Prinance does not request access to Gmail messages, contacts or files, and does not send your bank records to Google as part of sign-in. Google processes its own sign-in activity under its privacy policy.

If you use a passkey, your device or password manager verifies it. Prinance stores only its public key, never your device PIN, fingerprint or face data.

Necessary secure cookies keep your session and protect login requests against replay. There are no advertising or analytics cookies. Signing out revokes the current application session. The operator can arrange removal of login records and disable Google access; disabling the connection in your Google Account does not erase previously stored application records.

The application operator manages this private workspace. The full financial-data privacy notice is available inside the signed-in tracker.
