Permissions

Why Kinograph Tennis asks for the camera, the microphone, and Photos, and what it does with each.

Everything Kinograph Tennis does with these permissions happens on your iPhone.

Camera

Kinograph Tennis records your session and keeps your points. Everything else is held in memory for a few seconds and then discarded without being saved.

Microphone

Kinograph listens for the sound of the ball being struck, which is how it knows when to keep something, and records sound with the clips it keeps. The sound is analyzed on your iPhone and never sent anywhere.

Photos

• Trimming a video you already have. You pick it in the system’s photo picker, which hands Kinograph only that video. Nothing else in your library is shared.
• Saving a finished video. Kinograph asks to add it to your library.
• Replacing a video with its trimmed version. Only then does Kinograph ask to read and change your library, and only to replace that one video. Photos keeps the original underneath, so you can revert to it in the Photos app.

Privacy

There’s no account and no server, and Kinograph Tennis collects no data. See the privacy policy.
