About this app

Treadmill records indoor walking and running workouts. It is published by Soichiro Inatani. No account is required.

Information and its purpose

The app stores your weight, height, speed, incline, units, voice guidance and other preferences on your device. Weight is used to estimate calories; height is retained as profile information.

Workout dates, duration, speed and incline segments, walking or running mode, distance, estimated calories, elevation gain, program, distance corrections and steps are stored on your device for live metrics, history, charts and weekly totals.

Apple Health integration

With your permission, the app reads weight and height through HealthKit. When restoring history, it reads workouts, walking + running distance and active energy that this app saved to Apple Health.

If you choose to save to Apple Health, the app writes an indoor walking or running workout, distance and active energy. To support restoration, additional information such as weight, steps, speed and incline segments, program and distance corrections is stored in workout metadata and related samples.

Health and workout data is not used for advertising, sale or tracking. You can change HealthKit permissions in Apple Health or iOS settings. Manual workout recording works without HealthKit read or write permission.

Apple Watch and heart data

The Watch-enabled version uses permitted heart-rate readings for effort guidance and history charts. Settings, workout start/stop state, heart rate and completed records transfer between your paired iPhone and Watch and are stored locally, not sent to publisher servers.

iPhone and Watch each retain local data. Deleting history on one device does not delete the other device’s copy. Removing the app on each device removes its local data; manage saved Apple Health records separately.

Motion, speech and location

With permission, Core Motion provides steps and cadence during workouts. Steps may be inaccurate if your iPhone stays on the treadmill console.

Voice guidance uses Apple speech synthesis. The app does not record microphone audio or access GPS or location.

Transfers, advertising and analytics

The app does not send health or workout data to servers operated by the publisher. It includes no advertising SDK, behavioral analytics SDK or tracking features.

The app does not independently store health information in iCloud or CloudKit. Apple Health synchronization and operating system backups and diagnostics are managed according to your device settings and Apple services.

Opening the support or privacy website connects to GitHub Pages. Processing associated with website delivery, including IP addresses, is subject to GitHub’s privacy policy. If you email support, the publisher uses your email address and message to respond.

Storage, deletion and permissions

Swipe left on a workout in History to delete it from the app. Deleting the app removes its local history and preferences. Manage information included in operating system backups through your device backup settings.

Deleting a workout in the app, or deleting the app itself, does not delete records already saved to Apple Health. Select this app’s data in Apple Health to delete those records. Records remaining in Apple Health may be imported again when you restore history.

Health and motion permissions can be revoked in iOS or Apple Health settings. The publisher cannot remotely access records on your device or in Apple Health. You do not need to attach health data when contacting support.

Support emails are retained as needed to handle your request, and information no longer needed is deleted. Contact support if you would like your correspondence deleted.

Changes and contact

This policy may be updated when features or data handling change. The latest policy and update date are available on this page and in the app.
