The short version

You don't need an account to use Infil, and we don't ask for your name or email. Your level and checklist progress stay in your own browser. If ads are running, Google and its partners may use cookies to show and measure them.

What's stored on your device

When you enter your level or tick a checklist box, that's saved in your browser's local storage so it's still there next time. It never leaves your device and we can't see it. Clearing your browser data removes it.

Advertising

We use Google AdSense to show ads. Third-party vendors, including Google, use cookies to serve ads based on your previous visits to this and other websites. Google's advertising cookies let it and its partners serve ads to you based on those visits.

Visitors in the European Economic Area, the UK and Switzerland are asked for consent through a consent banner before personalized ads are shown, and can change that choice at any time.

Server logs

Like most websites, our hosting provider may keep standard server logs (IP address, browser type, pages requested) for security and performance. We don't use them to identify you.

Children

This site isn't directed at children under 13, and we don't knowingly collect personal information from them.
