1. Introduction This Privacy Policy outlines how the localQR Chrome Extension ("we", "our", or "the Extension") manages your information. As an offline QR code recognition tool, localQR is built with a core commitment to full user privacy, ensuring all operations run entirely on your local device.
2. Core Privacy Principle: 100% Local Processing localQR is designed as a fully offline QR code recognition extension. No data, including images, QR code content, or any user-related information, will ever be uploaded, transmitted, or shared to any external servers, third-party services, or our own backend systems.
All QR code scanning, image analysis, and decoding processes are executed locally within your Chrome browser, with zero network requests initiated by the extension at any time.
3. Information We Do Not Collect We explicitly do not access, collect, store or process the following types of information:
Any personal identifiable information (PII) such as your browsing history, account credentials, location data or contact details The content of QR codes you scan, including URLs, text, contact information or other embedded data Screenshots, images or visual content you input for QR code recognition Any usage statistics, behavior tracking data or performance metrics about how you use the extension
4. Local Data Storage The only data the extension may temporarily retain on your device is non-identifiable user preference settings (such as default scan mode, result display preferences), which are stored exclusively in Chrome's local storage (chrome.storage.local). This data never leaves your browser, and will be completely and permanently erased immediately when you uninstall the localQR extension.
5. No Third-Party Involvement localQR does not integrate any third-party analytics tools, advertising SDKs, tracking scripts or external APIs. There are no hidden data sharing channels, and no external parties can obtain any information generated during your use of the extension.
6. User Control & Data Deletion You have full control over all data related to localQR:
You can clear all extension local data at any time via Chrome's extension management page Uninstalling localQR will automatically remove all relevant local storage data without any residual files left on your device No backup or copy of your scan records will be created anywhere outside your own device
7. Changes to This Policy If we make updates to this Privacy Policy, the revised version will be released along with the extension update, with the "Last Updated" date modified accordingly. We will never reduce your privacy rights under this policy without your explicit consent.
