Library and practice
The prototype stores favorites, imported packs with their text, geometry and source declarations, results and study dates, and the welcome preference locally on your iPhone. Pack content may include names or other details entered by its supplier; the app does not anonymize them. A previous snapshot helps recover from an unreadable save. No account is required, and packs or progress are not uploaded.
Connectivity
The documented prototype has no advertising, analytics SDK, cloud backend, tracking or location access. Source addresses declared in packs are displayed as text and are not fetched automatically.
Imports and exports
Only files you select are read. When exporting a copy, you choose its destination, which has its own privacy practices. Backups contain the library and local progress in readable form, without additional encryption by the app. iOS may include app data in its backups according to your settings.
Deleting data
Reset local data in Settings removes imported packs, favorites, sessions and both recovery snapshots. You can also delete the app. Removing an individual pack does not delete earlier practice history. Manage exported files and device backups separately.
Purchase preparation
The reference prototype, version 0.1.0, did not make purchases. The commercial edition is incorporating StoreKit to request products, verify transactions and restore access with Apple. When those functions are used, Apple processes payment and provides signed purchase information; we do not receive card details. Developing this integration does not imply a published commercial offer.
