Privacy notice

We collect as little as we can. Reading this site does not require an account, and we set no tracking cookies.

When you read the site

Our server logs the time, the page, the response and the country your request came from, as reported by our network provider Cloudflare. It does not store your IP address.
We use Cloudflare Web Analytics, which counts visits without cookies and without identifying you.
To decide which advertisement, if any, may lawfully be shown, the page asks our server with your country (and, where licences are local, your region). Your address is used only to limit how often those requests can be made and is not stored.
Some pages load banner advertising from a third-party network, Adsterra, in a separate frame. That network may process your data under its own privacy policy; it runs only in markets where our rules allow it.
Your browser may store small settings for our calculators on your device. They never leave it.

Messages sent through the contact form, and the email address you give, are used only to reply and are kept for up to 12 months.
For advertising orders we keep your company name, contact email, website, target markets, licence details and campaign material for as long as needed to run the campaign and to meet accounting and legal duties.
Payments are processed by Whop. We never see or store your card details; Whop's privacy policy applies to the payment.

You can ask us what we hold about you, and ask us to correct or delete it, by writing to [email protected]. We do not sell personal data.
