No. Arithmetix has no accounts and no sign-in. The first time you open it, you set a parent PIN, save a one-time recovery code and add your first child. The PIN protects the grown-up area, purchases and external links.
Open the grown-up area (enter your parent PIN) and tap Add Child on the home screen.
Go to your child's dashboard (tap their card on the home screen), then tap the info icon in the top right to update their age.
Arithmetix is free for 7 days, then a one-time purchase. To restore it on a new or reset device, open the unlock screen and tap Restore Purchase, using the same Apple ID you bought it with.
Tap “Forgot PIN?” on the PIN screen and enter the recovery code you were shown when you set your PIN. You'll then choose a new PIN and get a new recovery code — keep it somewhere safe. If this device never had a recovery code (for example, you set your PIN in an older version), a grown-up can reset the PIN by answering a maths question instead.
Everything Arithmetix stores is on your device. To remove one child, delete their profile in the grown-up area. To remove everything, go to Settings → Delete all data on this device, or uninstall the app. If you used an earlier version that asked you to sign in, email blueflamegames@proton.me to have the data held for that version deleted.
No. Progress is saved on the device as your child plays, with no internet connection needed. Each device keeps its own progress. Your purchase works on every device signed in to the same Apple ID.
Check your child is using the same device and the same child profile as before. If the issue continues, email blueflamegames@proton.me with your device model and iOS version.
