Privacy

This site doesn't collect, store or share your personal information.

• No cookies, analytics or trackers. There are no third-party scripts, fonts or embeds.
• Calculations run in your browser. The details you enter (such as age group, sex or weight) are never sent to us.
• Settings in links. When you use the planner, your settings are written into the page address so you can bookmark or share them. Anyone you send that link to can see those settings.
• "Remember my settings" is optional and off by default. If you tick it, your settings are saved in your own browser's local storage on this device only, and never sent anywhere. Untick it, or press "Forget", to delete them.
• Hosting. The site is hosted on GitHub Pages. Like any web host, GitHub may log technical information such as IP addresses for security; see GitHub's privacy statement.
