Privacy Policy
LiftBook is a local workout planning and tracking app for iPhone. This policy describes the privacy practices for the initial version of LiftBook.
Data stored on your device
LiftBook stores your routines, workouts, workout history, exercise edits, app setup status, preferred weight unit, default rest timer duration, and rest timer notification preference locally on your device.
The initial version of LiftBook does not create user accounts, does not sync your workout data to a server, does not include advertising, and does not track you across apps or websites.
Analytics and diagnostics
LiftBook uses TelemetryDeck to collect anonymized product interaction analytics, such as whether onboarding was completed or whether a workout was started. These events do not include workout names, exercise names, reps, weight, routines, notes, or other fitness content that you enter in the app.
LiftBook uses Sentry to collect crash reports and limited performance diagnostics so the developer can find stability problems. Sentry is configured not to send default personally identifiable information.
Notifications
LiftBook can schedule local notifications for rest timers if you allow notifications. These notifications are created by iOS on your device and are used only to alert you when a rest timer ends.
External links
Some exercise details may include links to external video websites. Opening those links leaves LiftBook and may be subject to the privacy practices of the external website or app.
Data collection
LiftBook does not intentionally transmit the fitness data you enter, such as routines, workouts, exercises, reps, or weights, to LiftBook servers.
For analytics and diagnostics, LiftBook and its third-party service providers may collect data that is not linked to your identity, including device identifiers used for analytics, product interaction data, crash data, and performance data. This data is not used for tracking.
Future changes
If LiftBook adds cloud sync, accounts, advertising, tracking, or other network features in a future version, this policy and the App Store privacy information will be updated before that version is released.
