This site (KeyAudit / WeakSeed) follows a strict data-minimization policy:

What we do NOT collect

• The site never asks for nor stores any user-supplied private key, mnemonic, or brain-wallet passphrase. All derivation and lookup happens entirely in the browser.
• Wallet addresses submitted for lookup are processed only within the request lifecycle and are not written to logs.

Cookies & similar technologies

• Local storage (localStorage): saves your language preference, the "got it" state of the warning banner, and your recent lookup history — strictly inside your browser.
• Google Analytics (gtag.js, G-CKY6E9M8RE): used only for aggregate traffic statistics. You can opt out via the cookie banner at the bottom of any page; once declined, no analytics events are sent.

Leak dataset sources

All indexed wallet-leak records come from public datasets (ScamSniffer / MEW darklist / OFAC, etc.). See sources.
