गोपनीयता नीति

Updated: 02/10/2026

1. QR codes you create

Static QR codes are created entirely in your browser: the content (links, account numbers, Wi-Fi passwords...) and the logo you add are not sent to our server unless you click “Save to My QR codes” or turn on “Scan tracking”.

2. Data when you have an account

Sign-in uses the shared 27BigGroup account (email or Google). When you save a code, we store its content, design and the name you give it so we can show it back to you. You can delete codes at any time in “My QR codes”; the data is removed from our system immediately.

3. Scan statistics (dynamic QR)

For each dynamic QR scan we record the time, device type, operating system, browser and country (inferred from the network). We do not store IP addresses: only a one-way hash is kept to count unique scanners. Only the QR owner can see the statistics.

4. Cookies and advertising

The site uses session cookies to keep you signed in. We show ads from Google AdSense. Google and its partners use cookies to serve ads based on your visits to this and other websites. You can turn off personalised ads in Google Ads Settings, or learn more at policies.google.com/technologies/ads.

We also count page visits (we never sell data to third parties) to improve the service.
