Privacy

The short version: this site is readable, not extractive.

What we collect

• Calculator and quiz inputs: nothing. The tools on this site run entirely in your browser. Your age, hours and answers are never transmitted or stored by us.
• Server logs. Like nearly every website, our server records standard request logs (IP address, page requested, browser type, timestamp) used for security and capacity. Logs rotate and are not sold or shared.
• Analytics. We may use basic, aggregate page-view analytics to see which pages help people. We do not build individual profiles.

Cookies

The site itself sets no cookies for tracking. If advertising is ever introduced, ad partners may use cookies subject to their own policies, and this page will be updated first.

Third parties

Pages load fonts from Google Fonts, which involves your browser requesting font files from Google's servers. Outbound links (product makers, journals) are governed by those sites' own policies.

Children

The site is written for adults and does not knowingly collect anything from anyone, children included.

Contact

Questions or correction requests: use the contact details on the about page's parent company, or write to the postal address in our terms.
