The current version does not collect data

What we do not collect

The app does not ask for a name, birth date, school, phone number, email address, photos, contacts, precise location, or free-form text.

It contains no third-party advertising, analytics, attribution, crash-upload, social, account, third-party payment, or cross-app tracking SDKs. The one-time Full Learning Path purchase uses Apple StoreKit.

Course purchase

The app is free to download and offers one non-consumable Full Learning Path purchase. It is not a subscription. Apple processes payment, purchase history, and restoration. The app checks access on the device and does not send purchase or learning records to a developer server.

Learning records on this device

Started and completed courses, practice activity, selected stage, check-in results, and weekly challenge drafts are stored in the app's local space so learning can continue and progress can be shown.

If system backup is enabled, iOS may back up app data according to the user's settings. The user and Apple manage that backup; it is not an app account or developer cloud sync.

Grown-up controls

Grown-up Info is protected by a grown-up check. A grown-up can review the current privacy boundary and clear all local learning records after a second confirmation.

Policy changes

If accounts, developer servers, third-party analytics, third-party payments, cloud sync, or other data features are added, we will review the change and update this policy and the App Store privacy answers before enabling it.
