What Are Cookies?
Cookies are small text files stored on your device by your browser. They help websites remember your preferences and understand how you use the site.

Google Analytics
We use Google Analytics to understand how visitors interact with URSAQR. This helps us improve the site and prioritize features. Google Analytics collects information anonymously - it does not identify individual users. Data collected includes pages visited, time spent, browser type, and approximate location (country/city level). We have enabled IP anonymization so your full IP address is never logged.
Google AdSense
We use Google AdSense to display advertisements. AdSense uses cookies to serve ads based on your interests, limit how often you see an ad, and measure ad effectiveness. These are advertising cookies. You can control personalized ad settings at Google Ad Settings.
Other Third-Party Resources
URSAQR loads resources from the following third-party services. These services do not set cookies on this site but may process your IP address and browser information under their own policies:
- Google Fonts (fonts.googleapis.com, fonts.gstatic.com) - web font delivery
- Cloudflare CDN (cdnjs.cloudflare.com) - QR code generation, HTML-to-canvas, and ZIP libraries
Your Control
You can control or delete cookies through your browser settings. To opt out of Google Analytics, install the Google Analytics Opt-out Browser Add-on. To control ad personalization, visit Google Ad Settings.
What We Do NOT Do
- We do not sell or share your data with third parties beyond the essential ad and analytics services listed above.
- We do not store your QR codes, uploaded images, or generated content - everything runs locally in your browser.
- We do not use fingerprinting or any other user-identification technology beyond Google Analytics and AdSense cookies.

If we change how we use cookies, this page will be updated. The "Last updated" date at the top will reflect the most recent revision.
