Legal
Privacy policy.
The short version: this site is designed to need as little of your data as possible.
Last updated 12 June 2026.
What we collect
unspurious is a static educational website. Every interactive figure and tool runs entirely in your own browser — the simulations, the statistics, the charts. Nothing you do with the dials, sliders or sandboxes is transmitted to or stored by us.
Cookies and analytics
The site sets no advertising or tracking cookies of its own. If privacy-respecting, aggregate analytics are used to understand which pages are read, they are configured not to identify individual visitors. No personal profiles are built and no data is sold.
Fonts and third parties
The site loads typefaces from Google Fonts, which means your browser requests those font files from Google's servers; that request is subject to Google's own privacy terms. No other third-party content is embedded.
If you contact us by email, we keep your message only for as long as needed to reply and, where relevant, to act on a correction or suggestion. We do not add you to any list.
Changes
If this policy changes, the revised version will appear here with an updated date. Questions are welcome via the contact page.
