Frequently asked questions
How do I restore my purchases?
Open the Store in the game and tap Restore Purchases. Permanent unlocks (Remove Ads, category unlocks) come back on the same Apple ID or Google Play account. Consumable items such as Epsilon packs cannot be restored once they have been delivered.
Will I lose my progress if I reinstall?
Yes. Your progress is saved only on your device and is not backed up to our servers, so uninstalling the game or switching devices starts the game from the beginning. Permanent purchases can still be restored with Restore Purchases.
How do lives work?
You have up to 5 lives. A wrong answer or a timeout costs one, and one life refills every 30 minutes.
How do I delete my data?
Uninstalling the game deletes all game data on your device — we do not keep a copy. For other data, such as purchase records, email contact@math-maker.com — see section 9 of our Privacy Policy.
