Privacy
Last updated 10 September 2026
This policy covers qr.4brainslabs.com, operated by 4Brains Technologies Private Limited. It is short because the tool does very little with your data: almost nothing, in fact.
What you type stays on your device
Every QR code is generated inside your browser. The link, WiFi password, contact details, payment information or text you enter is never sent to us or to anyone else. There is no upload, no account and no storage. Close the tab and it is gone.
Scans are not tracked
A code made here contains your content directly. When someone scans it, their phone goes straight to your content. We are not in the path and cannot see that a scan happened. This is a deliberate design choice, not a limitation.
What the site does collect
- Server logs. Standard, short-lived access logs (IP address, browser type, page requested) kept for security and to keep the service running.
- Analytics. Google Analytics tells us which pages are visited and roughly where visitors come from, so we know which code types people need. It does not see what you type into the generator.
- Advertising. To keep the tool free we show ads served by Google AdSense. Google and its partners use cookies to serve ads based on your visits to this and other sites. You can opt out of personalised advertising at Google Ads Settings. Where the law requires it, for example in the EEA and the UK, Google’s consent message asks for your permission before advertising cookies are set.
- Fonts. Pages load typefaces from Google Fonts; your browser sends its IP address to Google as part of that request, as with any web resource.
Your rights
Because we hold nothing about you, there is nothing to access, correct or delete. For questions about this policy, email contact@4brains.in.
