Privacy policy
This policy describes the current Jump Today iOS app and this static support website. Last updated: September 10, 2026.
1. Who operates the app
Operator: 今日跳绳. Privacy and support email: support@anti.xin.
2. Camera and motion analysis
With camera permission, the app processes camera frames and body pose points on your device to determine readiness and count jumps. It does not perform facial recognition, create identity profiles or upload camera footage to the developer. Body pose points are used during processing rather than saved as a separate history of your movements.
3. Workout records and settings
Workout date, mode, target, count, duration and video references are stored in the app’s local storage. Preferences such as sounds, recording and music volume are stored on your device. The current app has no account system, advertising, tracking SDK or developer-operated analytics upload.
4. Optional recording and audio
Video recording is on by default and can be disabled in Settings for the next workout. Recordings combine camera footage, counts, time and generated count sounds. Background music is included only when the relevant settings are enabled. No microphone or ambient audio is captured. If recording fails, the app may retain a playable silent video and show a warning.
5. Photos permission
The app requests permission to add to Photos only when you choose to save a poster or video. It does not request access to read your photo library. Saved copies are managed by Photos and may sync through iCloud Photos if you enable that Apple service.
6. Storage, deletion and backups
Workout files remain in the app until you delete them or remove the app. Deleting a workout also attempts to remove its associated local video; any cleanup error is reported. Copies already saved to Photos are separate and must be deleted there. iOS backup or device-transfer services may include app data according to your Apple settings. Jump Today does not provide its own cloud synchronization.
7. Information you choose to send
If you contact support, the operator receives the email address, message and attachments you choose to send. Do not send workout videos or images of other people unless necessary and authorized. Support correspondence is used to answer your request and investigate the issue, and is kept only as needed for those purposes or applicable obligations. You can request deletion using the contact address.
8. Website and third parties
This website is hosted on Alibaba Cloud. The web server processes connection and access information, including IP address, request time, requested URL and browser information, to deliver pages and troubleshoot service issues. These static pages contain no analytics scripts, advertising or third-party embeds. Website access logs are separate from workout data, which the app does not upload. Apple’s platform, backup and Photos services are governed by Apple’s policies.
9. Your choices
You can revoke camera and Photos permissions in iOS Settings, turn recording off, change audio preferences and delete local workouts. No account deletion process is needed because the app has no accounts. For questions about support correspondence, contact the operator.
10. Children and updates
The app is not a social platform and has no messaging or public profiles. Children should use it with appropriate adult supervision and enough space to exercise. Changes to app data practices will be reflected in an updated policy; new uses requiring permission will request it.
