Privacy policy
Last updated 6 October 2026
We collect as little as possible. You don’t need an account to use this website, and we don’t run advertising trackers.
What we collect
- Analytics. We use DataFast to understand which pages are visited and which links, such as our Telegram button, are clicked. This records information like the page, referrer, approximate country, device type and browser. It may use a first-party identifier to count unique visitors. We use it only in aggregate.
- Server logs. Our hosting provider (Vercel) processes standard request data such as IP address and user agent to deliver the site, keep it secure and detect automated traffic.
- Calculators. Values you enter into our tools are processed in your browser and are not sent to us.
Telegram
When you join our Telegram channel, Telegram’s own privacy policy applies. As channel members, we can see that the channel has subscribers but not your phone number. We do not use member data for advertising.
How we use data
To run and improve the website and our content, to measure which pages are useful, and to protect the site against abuse. We do not sell personal data.
Your rights
Depending on where you live, you may have the right to access, correct or delete personal data about you, or to object to its processing. Contact us through our official Telegram channel and we will respond.
Changes
We will update this page if our practices change. The date at the top shows the latest version.
