The pages are static files. There is no account and no database.
Browser tools, including passwords, tokens, and pasted text, run on your device. They do not call this site. DNS lookup is the exception: the browser sends the name and record type to Cloudflare's public resolver at cloudflare-dns.com.
Network checks call a Worker on this site. The Worker does not store the check, the address, or the URL, and it does not write them to a log. A short counter limits how often one network can call it. That counter is not a record of what you looked up.
What Is My IP and IP Geolocation read the address and the coarse location Cloudflare attaches to this request. The city is approximate. Nothing from that request is stored. This site does not look up an address you paste.
Google Analytics loads on every page. Consent mode starts denied for analytics storage, ad storage, ad user data, and ad personalisation, so those cookies stay off until you accept. A cookieless measurement ping may still be sent. AdSense may set cookies only after that same choice. Reject keeps the four flags denied.
The ad frames stay empty until the ads.txt file from AdSense is in place.
Your consent choice is kept in local storage on this browser so the banner does not repeat. That value is not sent to the Worker.
