How can we help?

If you linked an email to your account, you can recover progress by entering that same email on the new device (Profile → Link email). You'll receive a 6-digit code to confirm. If you never linked an email and your account was anonymous, unfortunately progress isn't recoverable. We recommend linking email as soon as you have meaningful progress.

Check Spam, Promotions and Updates folders in Gmail. The email comes from pistari@logic4learn.com. If 5+ minutes pass without arrival, request it again from the app.

Non-consumable purchases (theme packs, full access) restore automatically when you reopen the app, as long as you're using the same Apple ID or Google account that originally purchased them. If they don't show up, go to Profile → Restore purchases. Hints (consumable) are tied to your account — if you had email linked, sign in with that email and they come back.

Refunds are managed by the store where you bought: App Store at reportaproblem.apple.com; Google Play from the Google Play app → My account → Orders. Logic4Learn doesn't have access to your payment data, so we can't process refunds directly.

Every puzzle in the bank is audited to confirm a unique solution, but if you found something odd, write to us with the puzzle number and a screenshot. We'll investigate and fix it in the next update.

Straight from the app: Profile → Delete my account, type the confirmation word and you're done — your progress, points, hints, leaderboard entry and, if linked, your email are erased. Immediate and irreversible. If you already uninstalled the app, follow the instructions at Delete your account (you can request it by email from the address you linked). Your purchases are not lost: they stay with your Apple ID or Google account and are restored when you reinstall.

Try: close it completely and reopen; restart your phone; check you have the latest version from the store. If nothing works, write to us with: device model, OS version, app version (Profile → About) and what you were doing when it crashed.

We're working on new packs. If you have "full access," you receive new themes added to the catalog at no cost for a period after your purchase (check the terms in effect at the time of purchase). If you have email linked, we'll notify you when something new is released.

For now we're focused on iPhone and Android. The same app is adapted for tablets. We're not ruling out web or desktop versions further down the line.
