Privacy Policy

Last updated: June 16, 2026 · Effective immediately

Pull-up Tracker (“we”, “the app”) is developed by Frank Deng. This policy explains how the iOS app handles information.

Summary

• We do not collect personal data.
• All pull-up logs (date and rep count), statistics, language preference, and related settings are stored locally on your device only.
• We do not use analytics, advertising, or third-party tracking SDKs.
• We do not require an account or sign-in.
• We do not operate a backend server for your workout data.

Information stored on your device

The app may store the following locally (for example, using on-device storage in the app’s WebView layer):

• Daily pull-up records (date and number of reps)
• Derived statistics such as totals, streaks, and chart data
• Your chosen app language (Chinese or English)

This data never leaves your device unless you choose to share it — for example, by generating a progress image and using the iOS share sheet (Messages, Photos, WeChat, AirDrop, etc.).

Share images

The Stats tab can generate a shareable image on your device. The image is created locally and shared only when you tap Share or Save. We do not receive a copy of shared images.

Permissions

The app does not require location, contacts, camera, microphone, or photo library access for core features. If you save or share an image through the system share sheet, that action is handled by iOS and the app you choose.

In-app purchases

Optional voluntary tips (“Support the Developer”) on the Stats tab are processed entirely by Apple through the App Store. We do not receive or store your payment card details. Apple may provide developers with anonymized purchase records as part of Apple’s developer services.

Children

The app is suitable for general audiences. We do not knowingly collect personal information from anyone, including children.

Changes

We may update this policy from time to time. The “Last updated” date at the top will change when we do. Continued use of the app after changes means you accept the updated policy.
