Privacy Policy

Last updated October 17, 2026

This policy covers the apps published by davechengapps: BendyBooth, BigMagnify, Chill and MuteKey.

Information we collect

We do not ask you to create an account, and we do not collect your name, email address or other personal information through the apps. Photos, videos, audio and settings you create stay on your device unless you choose to share them.

Camera, microphone and permissions

Some apps request access to the camera, microphone or photo library solely to provide their core features. This data is processed on your device and is not sent to us.

Face data in BendyBooth

BendyBooth uses the front camera's face tracking (Apple's ARKit, using the TrueDepth camera on supported devices) or Apple's Vision framework to find your face, so effects and props can follow it. This face data includes the position of your face and its features, how your head is turned, and whether your eyes are open.

Face data is processed entirely on your device. When you record, the face positions are saved on your device alongside that recording, so you can change effects and props after recording. Face data is never sent to us or to anyone else, is not included in the videos and photos you share, and is not used for advertising, analytics or to identify you.

Advertising and third parties

Free versions of some apps may show ads from third-party ad networks, which may use device identifiers to serve and measure ads under their own privacy policies. Purchases are handled by Apple; we never receive your payment details.

Children

We do not knowingly collect personal information from children.

Changes

We may update this policy from time to time. Changes will be posted on this page with a new date.
