Think Why / Privacy Policy
The current version does not collect data
This policy applies to Think Why iOS version 1.0 and is effective 18 August 2026.
In one sentence
No account is required, there are no adverts or tracking, and the app does not send learning records to a developer server.
What we do not collect
The app does not ask for a name, date of birth, 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.
