Guest mode vs. an account

You can use every feature of Student Planner without ever signing in.

Guest mode

Choosing Continue as guest starts a real (anonymous) session, but everything you enter — schedule, tasks, tests, study progress — stays only on that device, in its local storage. Nothing is ever uploaded. This means:

• It works fully offline, on the very first launch, with no signup step.
• If you clear your browser's site data, or uninstall the app, that data is gone for good — there's no backup, because nothing was ever synced.
• It won't show up on another device. Guest data is tied to the browser/device it was created on.

On iOS, Safari may automatically clear a web app's local storage if it goes unopened for about two weeks — a platform-wide rule, not specific to this app. Since guest data has no cloud backup, that would mean losing everything. If you're on iOS and plan to stick with guest mode, either open the app periodically or export your data as a manual backup.

Signing in with an account

Signing in (Google or email/password) syncs your data to the cloud, so it's available on every device you sign into. If you were already using the app as a guest, signing in upgrades that same session in place — everything you'd already entered as a guest comes with you automatically, nothing is lost or needs re-entering.

If you sign in with an account that already has its own data on another device (say, you set the app up on your phone first, then sign in on a laptop that also has guest data), the laptop keeps showing its own local guest data until you explicitly create a new account — signing into an existing account doesn't silently merge two separate sets of data together.

Switching later

You can start as a guest and create an account at any point from the Profile menu's Create an account button — nothing is lost in the process.
