Privacy Policy

1. 100% Client-Side Data Processing

At Angle Finder Protractor (anglefinderprotractor.com), user privacy is our highest priority. All angle calculations, HTML5 canvas operations, image uploads, and live camera streams via WebRTC are processed 100% locally inside your browser. No uploaded photos, video frames, coordinates, or measurement data are ever transmitted to or stored on any external server.

2. Camera & WebRTC Permission

Our web application offers an optional Live Camera Feed feature powered by the HTML5 WebRTC MediaDevices API. Camera access is strictly requested on-demand when you click "Start Camera Feed". The video stream remains contained within your local device session and is never recorded or streamed to any remote destination.

3. Local Storage & Theme Preferences

We use browser localStorage solely to remember your UI display preference (Light Mode vs Dark Mode) and your cookie-consent choice. No personal identification data is stored in your browser storage.

4. Cookies & Advertising (Google AdSense & Third Parties)

Third-party vendors, including Google AdSense, may use cookies to serve ads based on a user's prior visits to our website or other websites. Google's use of advertising cookies enables it and its partners to serve ads to users based on their visit to our sites and/or other sites on the Internet.

Users may opt out of personalized advertising by visiting Google Ads personalization settings. Alternatively, users can opt out of third-party vendor’s use of cookies for personalized advertising by visiting the Network Advertising Initiative opt-out page.

5. Advertising Consent Banner

Before any advertising script is loaded, a consent banner asks whether you agree to advertising cookies and personalized advertising. If you accept, the Google AdSense script may load and a record of your choice is kept in your browser (localStorage). If you decline, advertising scripts stay disabled and only non-personalized advertising is possible. You can change your choice at any time by clearing the site data in your browser, which resets the banner.
