Yes. Core workout logging is local-first and works without a network connection. Optional features such as sign-in, cloud sync, catalog updates, and Apple Health / Health Connect export need connectivity when you use them.
On iOS: Insights → Apple Health, enable sync, and allow write access when iOS asks. On Android: Account → Health Connect (when available). Finished sessions can appear in Health / Fitness. Gym Logbook does not estimate or write calories.
You can use the app as a guest. To link an account, open Account from the Workout tab and choose Sign in with Apple (iOS) or Google. Both providers can link to the same account on iOS.
Use Insights → Export / Import for a full backup (JSON or CSV ZIP). When signed in, finished workouts can also sync to your account. In-progress sessions stay on the device until you finish them.
Open History → Recycle Bin. Soft-deleted workouts can be restored for 30 days.
