Privacy

Flueency doesn't ask you to sign in and doesn't run advertising trackers. Pages are served as static files.

We use privacy-focused, cookie-free web analytics that count page views in aggregate. No personal profile is built.

The calculators run entirely in your browser; the numbers you type aren't sent to us.

When you follow a link to a retailer, that retailer's own privacy policy applies, and it may use cookies to record that you came from Flueency.
