Privacy policy

The calculator does not require an account and does not ask for personal data.

Your current build, saved builds and language choice are stored only in your browser's local storage. They are not sent to our server, and you can delete them at any time by clearing this site's data in your browser.

Our hosting provider may keep standard server logs, such as IP address, browser type and time of request, for security and to keep the service running.

We use Cloudflare Web Analytics to count visits and see which pages are popular. It does not use cookies, does not track you across sites and does not create a profile of you; we only see aggregated statistics.

With your consent, we also use Google Analytics 4 to see how the calculator is used (for example which pages and features are popular) and how fast pages load for visitors. Google Analytics sets cookies and processes data such as your IP address and device information, possibly also in the USA. In the EU/EEA, the UK and Switzerland, cookies are used only after you agree in the consent banner; without consent only anonymous signals without cookies are sent. You can change your choice at any time via “Privacy settings” at the bottom of the page.

If advertising is shown on this site, advertising partners such as Google may use cookies or similar technologies to show and measure ads. Where the law requires it, we ask for your consent first, and you can change your choice at any time.

The “Send feedback” form is anonymous. We store only the message, its type, the page language and, if you tick the box, your build code, and use them solely to improve the calculator. The form is protected from spam by Cloudflare Turnstile, which processes technical browser data for that purpose. To limit submissions we keep a one-way salted hash of your IP address for at most one day; the IP address itself is not stored.
