Privacy Policy
Last updated 20 September 2026
What you type stays with you
Names, heights and other values you enter on a board are held in your browser while you use the page. HeightViz has no accounts and stores nothing you type in a database. Two things do travel: a share link encodes those values in the link itself, so opening or sharing one sends them to our server as part of the web address, where they appear in ordinary request logs; an embed does the same and its rendered image is cached for a day. Anyone you give a link to can read the values in it. HeightViz does not keep a copy of the links you create.
Browser storage
Two things are kept in your browser's local storage: your “you” height and the boards you save. They never leave your device, they are never sent to analytics, and you can clear them through your browser settings or from the saved-boards page. An image you add to a board is held in the page only, is left out of share links, embeds and saved boards, and disappears when you reload.
Analytics
This deployment does not send analytics. When analytics are enabled, they count page views and tool interactions only; no value you type is sent, and page addresses are sent without their query string.
Cookies
HeightViz sets no cookies of its own. Analytics, when enabled, may set the cookies described in Google's documentation.
Third-party links
Source links lead to league, zoo, museum, manufacturer and reference sites. Their privacy practices are their own.
