What we publish
Circumify publishes free geometry calculators and plain explanations of circle maths. We use standard, well-established formulas, and we show the working so you can check it.
Corrections
If you find an error in a result or an article, email [email protected]. We check the report and fix what is wrong.
Paid content
We accept paid articles. Every one shows a "Paid partnership" label, and gambling content also shows an 18+ notice. Payment does not change our calculators or our own articles. Our write for us page sets out what we accept and refuse.
Advertisers are responsible for the legality of their content and links in the markets they target. Gambling and other age-restricted content is for adults (18+) only.
