Information the app may process

The app may process user-selected videos, file metadata, the selected impact frame or time, shuttle position marks, analysis results, a private app session identifier, and basic technical logs needed to operate, debug, and secure the service.

Video upload and private analysis

Uploaded videos are sent to https://api.keshuyang.com for private analysis. Uploaded videos may be stored so the app can provide in-app history. Users can delete uploaded videos from the History screen.

How information is used
