HahaFit Privacy Policy
HahaFit has no account system and no developer server for storing workout data. Workout plans and completion history are not uploaded to the cloud or synced to your other devices.
Data stored on your device
The following information is kept only in the app's local storage on your device and is not collected by us:
- Workout plans: exercise type, sets, repetitions, selected days, reminder time, and archive state.
- Completion records: workout dates, total training days, and streaks calculated on your device.
- Reminder state needed for on-device alarms and notifications.
HahaFit has no login and no advertising.
Umeng SDK (analytics)
We use the Umeng SDK, operated by Umeng Tongxin (Beijing) Technology Co., Ltd., for aggregated analytics such as new and active users, so that we can improve the app. The SDK may process device and network information, including available device identifiers (such as IDFA, IDFV, OpenUDID, and GUID), device model, OS and app version, language, time zone, IP address, network status, distribution channel, and session time.
We do not send workout plans, completion records, camera frames, audio, or raw pose data to Umeng, and do not use these data for targeted advertising or cross-app tracking. See Umeng's Privacy Policy for its information practices.
Camera
The camera is used only while recognizing push-ups, pull-ups, crunches, and squats. Frames are processed in real time on your device to determine repetitions. We do not save or upload photos or video, and the camera stops when you leave the recognition screen.
Permissions
- Camera: used only for on-device repetition counting.
- Alarm and notifications: used only to remind you at the workout times you set.
You can change these permissions at any time in iOS Settings.
Deletion and contact
Deleting a workout removes its local plan and completion history. Uninstalling HahaFit deletes all app data on that device. For questions, contact ling_start@126.com.
