Hearts

Each lesson uses one heart. Hearts come back over time; tap the counter at the top of the path to see when the next one arrives. The subscription gives unlimited hearts.

Subscription

• Cancel it: on iPhone, Settings → [your name] → Subscriptions → Masteries. On Android, Google Play → Payments & subscriptions → Subscriptions. Deleting the app does not cancel the subscription.
• Get it back on another phone: sign in with the same Apple or Google account, open the subscription offer in the app and tap "Restore purchases".
• Ask for a refund: payments go through Apple or Google. On iPhone: reportaproblem.apple.com. On Android: Google Play's "Refunds" help page.

Account

• Sign in: enter your email address, then the code you receive by email. No code? Check your spam folder, then ask for a new one.
• Without an account, your progress stays on the phone and is lost if you uninstall the app. Create an account to back it up.
• Delete your account: Profile → Edit my information → Delete account. The account and its data are erased.
• Delete your account without the app: write to contact@masteries.app from your account's email address, with the subject "Delete my account". The account and its data are erased within one month.
