Without an account, everything stays in your browser. With an account, lum9a stores your name, your passkey's public key, and your app data (tasks, progress, world, settings, and your Canvas calendar link if you add one) so it can sync between your devices. lum9a never sees your Face ID, fingerprint or device passcode.
If you turn on phone alerts, lum9a stores your device's push address and time zone so it can send reminders you chose. Turn them off any time in your browser or phone settings.
lum9a reads your Canvas calendar feed only to show your assignments. It cannot see your grades, submit work, or change anything in Canvas.
