Privacy Policy & Data Notice
Zero Cloud Processing Guarantee
At TheProtractor.com, we believe measurement tools should be private, secure, and fast. All images uploaded and angles measured are processed strictly client-side within your browser. No image files, coordinates, or measurement data are ever uploaded to any external server or third-party service.
1. Local Storage and IndexedDB
To make your experience seamless, our application saves your current workspace (including background images and measurements) in your browser's local IndexedDB and user preferences (such as light/dark mode and angle units) in localStorage.
Important Note: Certain browsers (particularly Apple Safari on iOS and macOS) may automatically evict locally stored site data after periods of user inactivity (often 7 days). We strongly recommend using the Export Image feature to save finished work.
2. No Analytics or Third-Party Tracking
The Protractor runs without any third-party tracking scripts, advertising trackers, or external font requests. Fonts (Inter Variable) and all application assets are self-hosted directly on the domain.
3. Managing and Deleting Your Data
You have complete control over your data at all times:
- Clear Workspace: Resets the current canvas and measurements while keeping your application settings.
- Delete Local Data: Completely purges all stored IndexedDB workspaces and preferences from your browser.
- You can also clear site data at any time via your browser's developer tools or privacy settings.
