Privacy policy
Last updated 10 November 2026.
In short: this website does not ask for your name, does not need an account, and does not use advertising, tracking cookies or analytics. We do not collect or store personal information.
Settings kept on your device
A few choices are saved only in your own browser, so the site remembers them next time. They are never sent to us:
- whether you last used Run & Ride or Swim;
- the place you last picked on each island's page;
- whether "Use my location" is switched on for the lightning watch.
You can remove these at any time by clearing this site's data in your browser settings.
Your location
If you tap Use my location on the lightning card, your phone asks your permission first. Your position is used only inside the page, on your device, to work out the distance to recent lightning. It is never sent to us or stored, and you can switch it off again with the same button.
Services the page connects to
Like most websites, the page loads parts from other services, which receive your device's internet address (IP address) as a normal part of loading:
- GitHub Pages hosts the website;
- Google Fonts provides the typefaces;
- Google Apps Script provides the live lightning feed.
We do not receive or keep these addresses. Each service handles them under its own privacy policy.
Changes
If this policy changes, the date at the top will be updated.
