Cookie Policy
Last updated 19 September 2026.
We ask for your consent before setting any cookie beyond what's strictly necessary, via the banner shown on your first visit. Your choice is remembered in your browser and re-applied on every later visit, until you change it.
Strictly necessary (always on)
This site doesn't currently set any strictly-necessary cookie. Your unit preference (cm vs feet/inches) and your cookie consent choice itself are both kept in your browser's local storage, not a cookie — functionally similar, but technically distinct, and not sent back to a server on every request the way a cookie is.

heightversus:unit (local storage) |

Google Analytics (GA4) | Maintains session state | ~2 years |
Advertising (optional, not yet active)
This site plans to show ads via Google AdSense once launched and approved. Once active, this
category will only be set if you accept it, and will cover AdSense's own cookies (for example
IDE, test_cookie) used for ad delivery and, where consented,
personalisation. This section will be filled in with AdSense's exact cookie list once that's
live.
Changing your choice
Clear this site's data in your browser settings to see the consent banner again, or use your
browser's cookie/site-data controls to remove _ga and related cookies directly at
any time.
See Privacy Policy for how any data collected via these cookies is used.
