Privacy
Last updated October 12, 2026.
Burrow Logic has no accounts and no server that stores anything about you. You don't sign up, and we don't ask for your name or email.
What's saved, and where
Your puzzle progress, settings, streak and garden are saved in your browser's storage on your own device. They never leave it. Clearing your browser data, or not visiting for a long time on some browsers, can erase them. Adding Burrow Logic to your home screen helps keep them.
What we don't do
We don't use cookies, analytics or advertising trackers, and we don't sell or share data. Puzzles are created on your device from the date, so playing doesn't send anything to us.
Advertising
Burrow Logic shows a few ads to stay free: a banner on the home page, a banner at the bottom of the Garden tab, and now and then a full-screen ad between practice puzzles. There are never ads during the daily puzzle. The ads come from Google AdSense.
Google and its partners may use cookies or similar technologies to show these ads, limit how often you see the same one, and measure them. In the EU, the UK and Switzerland you'll be asked for your choice first, and you can change it at any time. You can read how Google uses information from sites that use its services and manage ad personalization in My Ad Center.
We don't use analytics, we don't sell data, and your puzzles and garden still never leave your device.
Tips
If you leave a tip through Ko-fi, Ko-fi handles the payment on its own site. We never see your card details.
Other services
The site is hosted by Cloudflare, which handles web requests and may keep standard server logs, such as IP addresses, for security. Fonts load from Google Fonts. Their own privacy policies apply.
Changes and contact
If we add ads, analytics or accounts, this page will say so before they start. Questions: burrowlogic@3351labs.com.
