CamTuner is a browser extension and web application that lets you crop, zoom, and align your webcam feed. We are committed to protecting your privacy. This policy explains what data we collect, how we use it, and your rights.
We do not collect any personal data.
CamTuner processes your webcam feed entirely within your browser. No video frames, images, or audio data ever leave your device. All cropping, zooming, and alignment operations are performed locally using the Canvas API and WebCodecs.
CamTuner stores your preferences (aspect ratio, zoom level, alignment, letterbox color) in your browser's local storage using the Chrome Storage API. This data never leaves your device and is not transmitted to any server.
The extension requires camera access to modify your video feed. This permission is used solely to apply your configured adjustments in real-time. We never record, transmit, or store any video or audio data.
CamTuner does not integrate with any third-party analytics, advertising, or tracking services. We do not use cookies or any form of user tracking.
We do not share, sell, or transfer any user data to third parties, because we do not collect any data in the first place.
If we update this privacy policy, we will publish the revised version on this page with an updated date. Continued use of CamTuner after any changes constitutes acceptance of the revised policy.
If you have questions about this privacy policy, please open an issue on our GitHub repository.
