What this site receives when you use it
The calculators themselves receive nothing. Inputs go from the keyboard to the JavaScript engine on your own device; there is no server-side computation and no analytics endpoint that sees your numbers. The seed verifier performs PBKDF2 in your browser: a recovery phrase pasted here is never transmitted, ever — you can confirm it by opening your browser's network panel and watching nothing happen.
What the ad and measurement partners receive
Google AdSense, which serves this site's ads, may set cookies and process standard request data (IP-derived coarse location, page URL) under its own policy. Visitors in the EU/UK and California can exercise consent and "Do Not Sell or Share" choices via the consent tool shown on first visit or the footer link. No other trackers or pixels are loaded.
Log files
The web server records standard request logs (timestamp, path, user agent) for security and capacity purposes. They are not joined to anything and roll off routinely.
Caliculations you save
Nothing is stored by the site. There are no accounts, so there is no account to breach.
