Data stored on your device
HiInterval stores the workout plans you create, your exercise catalogue including body areas and tags, your selected plan, preferences, completed workout history, and local usage information needed for the future access model. This data is stored in the app's local iOS container.
Optional workout logo photos are chosen through Apple's system photo picker without granting HiInterval full photo-library access. A resized copy stays in the app's local storage, including while referenced by a completed workout. Photos are not uploaded to a server.
No account, backend, or analytics
The app does not require sign-in. It does not send workout history to a HiInterval server, and the current codebase contains no analytics, advertising, or tracking service.
Notifications
If you enable workout reminders, HiInterval asks iOS for notification permission and schedules repeating notifications locally on the device. Reminder settings are kept in the app's local preferences.
Audio and haptics
Workout tones, spoken cues, haptics, music ducking, and countdown cues are device features used while your workout runs. HiInterval does not record microphone audio or upload cue activity.
History export
You can export workout history as CSV using the iOS share sheet. The destination is chosen by you. HiInterval itself does not automatically upload exported history anywhere.
Future purchases
Early access is free and currently has no purchase prompt. When paid unlimited access launches, purchases are planned through Apple's in-app purchase system. Apple processes the payment and may apply its own privacy terms to App Store transactions.
Deleting app data
Because HiInterval's data is local, deleting the app removes its local application data according to iOS behavior. Individual history entries and workout plans can also be managed inside the app.
