Privacy

No accounts, no cookies, no analytics, no ads and no tracking pixels. Nothing you type into the calculator is sent to us.

To keep your place, the site saves your calculator settings, library filters and, if you use dosing by weight, your body weight in your browser’s local storage. It stays on your device, and you can clear it here.

If you use the dose log, your vials, doses, injection sites and notes are saved the same way, only on this device, and anyone who uses this browser can see them. The button below leaves the log alone; export or delete it on the dose log page.

The site’s fonts load from Google Fonts, so your browser sends Google your IP address and basic browser details when a page loads. Google’s own privacy policy covers that data.

Like any web host, ours keeps standard server logs, such as IP address, browser and the page requested, to run and secure the site.

A calculator share link holds only the numbers on screen, never your body weight. Calendar files from the supply planner are made in your browser and saved straight to your device.
