Privacy policy
Short version: we do not ask for your name or email, and the tools never send what you type anywhere.
What we collect
The site is static pages hosted on GitHub Pages. GitHub may keep standard server logs (such as IP addresses) for security; see GitHub's privacy statement. Fonts load from Google Fonts.
Free tools
All calculators, including the password checker, run entirely inside your browser. Nothing is uploaded.
Live Wire
The Hacker News box asks the public Hacker News search service for the current front page directly from your browser.
Affiliate links and ads
If you click an affiliate link, the partner may set cookies to credit the referral, under their own privacy policy. If we add advertising later, this page will be updated first.
