This app does not require its own account registration and does not transmit any personal information to our servers.
Your detailed learning records, journal entries, and drill-history storage data are stored only in the following locations:
When iCloud is enabled, your learning data is automatically stored in iCloud Drive to sync across your devices signed in with the same Apple ID. Data is encrypted and managed by Apple's infrastructure; we cannot access it.
If you prefer not to use iCloud, turn off Boki Lens under iOS Settings > Apple ID > iCloud > iCloud Drive. In that case, data is stored only on your device.
Premium purchases are processed through Apple's App Store. This app does not collect or store your payment information.
To improve the app, we use TelemetryDeck (TelemetryDeck GmbH), a privacy-focused analytics service, to collect anonymous usage events. We send only an anonymized hashed identifier and interaction events that describe screens, features, learning-progress states, and purchase-success events.
Learning-progress events may include stage IDs, lesson IDs, solved counts, and correct counts. Purchase-success events may include the plan name and product ID. This app does not use advertising SDKs. Analytics data is not linked to you personally and is never used for advertising or tracking.
