Privacy policy

kb does not collect any data. There are no accounts, no analytics, no advertising, and no third-party services. The app makes no network requests of its own.

Your typing history — lesson results, per-key statistics, settings, book reading positions, and imported books — is stored on your device.

If iCloud is enabled on your device, this data syncs through iCloud to your other devices using your private iCloud database. That data is governed by Apple's iCloud terms and is not visible to the developer. You can disable iCloud sync for kb in your device's iCloud settings.

Purchases are handled by the App Store; the developer never sees your payment details.

If this policy changes, the change will be described on this page.
