What to include

If you're reporting a problem, it helps to mention:

Which exercise (Alphabet, Rainbow, Square Breathing, NASA, Triple Description, Walk of Power, or Croydon Ball).
Which device (iPhone, iPad, Apple TV, or Mac) and OS version.
The app version (Settings → About → Version).
What you were doing when it happened, and what you expected.

Purchases

Alphabet is free. The other six exercises are unlocked by a single one-time in-app purchase, handled by Apple's StoreKit. Bought the unlock on one device? Tap Settings → Purchases → Restore purchases on any other device signed into the same Apple ID.

Promo codes redeem in the App Store app — open it, tap your profile, choose Redeem Gift Card or Code, and paste the code.

What we don't collect

The app doesn't create accounts, doesn't sync, and has no server of our own. The exercises run on-device; the only network activity is Apple's StoreKit talking to Apple for purchases and restores. See the privacy policy for details.
