Data you enter

All calculations happen in your browser. Nothing you enter is transmitted to our servers or stored.

Analytics

We use Cloudflare Web Analytics to count visits. It does not use cookies or fingerprint visitors and only records aggregated data such as pages viewed, referring site, country and device type.

Advertising

We may display advertisements served by Google AdSense. Google and its partners may use cookies to serve ads based on your prior visits to this or other websites. You can opt out of personalised advertising at Google Ads Settings.

Pro waitlist

We keep an anonymous daily count, per site, of how many visits see the Pro box and how many tap its button. No IP address, cookie or device details are kept. If you choose to type an email address in that box, we store only the address, the site and the date, use it once to tell you when Pro launches, and then delete it.

Cookies

The site itself sets no cookies. Third-party services named above may set their own, subject to their policies.
