Privacy
In short: we don't ask for, collect or keep your data. The details, including about the site's host, are below.
What you enter into the calculators
Every calculation runs in your browser. Amounts and other values are not sent anywhere and not saved: once you close the page, they exist nowhere.
Cookies, ads and analytics
The site sets no cookies, shows no ads and uses no visit counters or analytics services. Fonts and every other file load from the site itself, so the pages make no requests to third-party services.
Hosting
The site is hosted on GitHub Pages. According to GitHub, when a GitHub Pages site is visited, the visitor's IP address is logged and stored for security purposes. GitHub keeps those records under its own privacy statement; we have no access to them.
Links to other sites
The source lists link to government, bank and transfer-service websites. Once you follow those links, those sites' own rules apply.
Messages on GitHub
If you write to us through GitHub, your message and your username are public and stored by GitHub. Do not include personal details.
Changes
If any of this changes, for example if analytics is added, we will update this page. This version applies from October 27, 2026.
