Privacy Policy
Overview
Kod — QR Scanner is a Chrome browser extension that detects and decodes QR codes found on web pages, in uploaded images, and via webcam. This policy describes what data the Extension accesses, how it is processed, and what is stored.
Data Processing
All processing happens locally on your device. The Extension does not operate any servers, does not send image data or QR results to any external service, and does not include analytics or telemetry of any kind.
What the Extension Reads
- Page images — when you trigger a scan, the Extension collects image URLs from the current tab (img elements, canvas, inline SVGs, CSS backgrounds) and downloads those images locally to search for QR codes.
- Webcam feed — when you use the camera scan feature, the Extension accesses
your device camera via the standard browser
getUserMediaAPI. Video frames are processed locally and immediately discarded after a QR code is found. - Uploaded files — images you drag-and-drop or select via the file picker are processed locally in memory and never written to disk outside the browser's own storage.
What the Extension Stores
Scan results (decoded QR text, a small image thumbnail, timestamp, and the URL of the source page) are saved to browser-local IndexedDB storage on your device. This data:
- Never leaves your device
- Is not synced across devices
- Can be cleared at any time by removing the Extension or clearing browser storage
Data Sharing
The Extension does not sell, transfer, or share any user data with third parties. No data is used for advertising, profiling, or any purpose unrelated to decoding QR codes.
Camera Access
Camera access is requested only when you explicitly click the "With Camera" button. The Extension never accesses the camera in the background or without your direct action. You can revoke camera permission at any time via Chrome's site settings.
Changes to This Policy
If the Extension is updated in a way that affects data handling, this policy will be updated and the "Last updated" date will change.
