Do I need an account to use Tabbller?

No. Tap Join as Guest on the first screen and everything works — no email address, no password, nothing to type.

What is signing in for, then?

Only to keep your progress. A guest account lives on one device; signing in with Apple or Google saves your quiz history and learning progress so they survive a reinstall and follow you to your other devices.

How do I sign in?

On the first screen, choose Sign in with Apple or Google instead of Join as Guest. If you are already playing as a guest, open Settings and tap Sync — your existing progress moves across. Sign in with Apple is available on iPhone, iPad and Mac; Google is available on every platform, including the browser version.

I signed in with Apple and chose “Hide My Email”. Is that a problem?

Not at all. Apple gives us a forwarding address ending in @privaterelay.appleid.com and we never see your real one. That forwarding address is what the app shows on your profile. Deleting your account does not ask you to type it, or anything else, back in.

Does Tabbller work offline?

Yes, once you have signed in for the first time. Quizzes and progress are saved on the device and sync when you reconnect. The very first sign-in needs a connection.

My progress has not synced.

Check that the device is online — the app shows a banner when it is not. Progress saved offline is queued and uploaded the next time you open the app with a connection. If a quiz is still missing after that, email us and tell us roughly when you took it.

I cannot sign in.

Make sure you are online, then close and reopen the app. If sign-in still fails, tell us which method you used and what the error said — a screenshot is ideal. You can always continue as a guest in the meantime; nothing is lost.

Is there any advertising, or anything to buy?

No. Tabbller is free, has no adverts, no in-app purchases and no third-party analytics. See the Privacy Policy for exactly what is stored and why.

Is it suitable for children?

Yes. A guest account needs no name, no email address and no sign-in at all, which is the option we recommend for a child. See the Privacy Policy for details.
