Privacy policy
Short version: we collect almost nothing.
Effective October 24, 2026.
What we collect
You can read every page and use every tool without creating an account or giving us any personal information. Our calculators run entirely in your browser; the numbers you enter are not transmitted to us or anyone else.
The site is hosted on Cloudflare, which processes standard technical data (such as IP addresses and request logs) to deliver pages securely. We may use privacy-focused, cookie-free aggregate analytics to understand which pages are read. We do not use advertising trackers or sell data.
If you email us
If you write to [email protected], we receive your email address and message and use them only to reply. We don't add you to any list unless you ask.
Purchases
Digital products are sold through a third-party checkout (such as Payhip), which processes your payment and email under its own privacy policy. We receive your name, email and order details to deliver the product.
Links to other sites
We link to government agencies, exchanges and other sources. Their privacy practices are their own.
Changes and contact
If this policy changes, we'll update the date above. Questions: [email protected].
