Security

Last updated 21 September 2026

Signing in

You can sign in with an email address and password, or with Google. Passwords are handled by the managed sign-in service and are never visible to this app.

Account-level isolation

Every item and cost carries the account that created it. Access rules in the database allow a signed-in person to read, add, change and delete only their own rows — a request for anyone else's data returns nothing, even if it is made directly against the database.

Protected pages

The dashboard, inventory sections and business costs are behind sign-in. If your session ends you are sent back to the sign-in screen, and cached figures are cleared when you sign out.

Connections

All traffic between your browser and the app is encrypted over HTTPS.

Good practice on your side

Use a password you do not reuse elsewhere, and sign out on shared computers. If you ever think your account has been accessed by someone else, change your password immediately.

Reporting a problem

If you spot something that looks like a security issue, report it to the account owner of this app.
