SnapDust is a browser extension that adds a “turn to dust” effect to your own camera image in Google Meet. This policy explains what it does with your camera, microphone and settings. In short: everything stays on your device. SnapDust collects nothing and sends nothing anywhere.
When Google Meet turns on your camera, SnapDust processes each video frame on your computer to find where you are in the picture, to remember what your room looks like behind you, and to draw the effect. The processed video is handed back to Google Meet, which sends it to the call exactly as it would send your normal camera image.
SnapDust does not record, save or upload any video or image. The picture of your room it keeps for the effect exists only in your browser’s memory while the Meet tab is open, and is gone when you close the tab.
To recognise a finger snap by its sound, SnapDust listens to the microphone that Google Meet has already opened. It analyses the sound on your computer, a few milliseconds at a time, only to decide whether a sharp click was a snap. No audio is recorded, saved or transmitted.
So that a snap works while you are muted in Meet, SnapDust keeps listening while Meet’s mute is on, which can keep your computer’s microphone indicator lit. If you don’t want this, choose Hand only under “Detect by” in the SnapDust popup: it then doesn’t use the microphone at all. When Google Meet closes the microphone, SnapDust stops listening too.
To recognise a snap by its movement, SnapDust looks for your hand in the camera image, on your computer, as described under Camera.
Your SnapDust settings (for example the detection mode and sensitivity) are saved in your browser’s local extension storage on this computer. They are not synced or sent anywhere. Uninstalling SnapDust deletes them.
If SnapDust ever changes how it handles data, this page will be updated before that version is released, and the change will be noted in the release notes on GitHub.
