CoachAid (“the app”) is a sports video analysis application for iPhone and iPad, published by Weijie Jin. This policy explains how we handle information when you use the app.
The app is designed to work primarily on your device:
We do not require an account or sign-in to use CoachAid.
We do not collect, transmit, or sell personal information from the app. We do not operate backend servers that receive your videos. All user media and annotated content remain strictly local to your physical device.
The app uses Apple system frameworks (Photos, Camera, AVFoundation). Apple’s standard privacy policies apply to data handled by iOS. We do not embed third-party advertising SDKs or analytics services in the current version of the app.
The app is not directed at children under 13. We do not knowingly collect or store personal information from children.
Uninstalling the app removes local app data subject to standard iOS behavior. You may delete individual videos or comparison projects inside the app’s library at any time.
We rely on device-level security controls provided by Apple iOS. Please ensure your device is passcode protected. Do not share exported videos beyond what you intend to make public.
