Privacy
No cookies, no browser storage, no analytics, no accounts. Every file the
page loads comes from this site. The plot you build is held in the address
bar after the #, which is how a plot can be shared as a link,
and it goes nowhere unless you send the link yourself.
The page is served by GitHub Pages and the cross section data by Cloudflare, so those two see your IP address in their logs in order to deliver it. Nothing else is collected and no record of your visit is kept here.
Jon Shimwell runs this site. Anything you want to ask or object to, including about your own data, goes to mail@jshimwell.com. You can also complain to your national data protection authority.
