Cookie Policy
Last updated 11 August 2026. This site does not use cookies. It also does not use local storage, session storage, tracking pixels, fingerprinting or any other technology for storing or reading information on your device.
That is why you were never shown a cookie banner. There is no consent to collect, because there is nothing to consent to. If you ever see a cookie prompt on this domain, treat it as suspicious and let us know.
What we do not set
- Strictly necessary cookies — none. The site is static and stateless; there is no session to maintain.
- Preference cookies — none. There are no settings to remember, and calculator selections are deliberately not persisted.
- Analytics or performance cookies — none. We run no analytics of any kind.
- Advertising or targeting cookies — none. We do no advertising and no remarketing.
- Local storage, session storage, IndexedDB — unused. Your calculator inputs live in page memory only and disappear when you close or reload the tab.
Third-party requests
Your browser makes exactly one category of third-party request: it downloads the Geist and Geist Mono typefaces from Google Fonts (fonts.googleapis.com and fonts.gstatic.com). Google states that font requests do not set cookies. Google does receive your IP address as an unavoidable part of serving the files, which we explain in our Privacy Policy.
There are no embedded videos, no social media widgets, no chat bubbles, no maps, no A/B testing tools and no tag managers — the usual sources of third-party cookies on a marketing site.
When you submit the form at the end of a calculator, the details go to this site’s own server, which forwards them to us by email through our delivery provider. That happens server-side and sets no cookie in your browser. What we do with those details is covered in the Privacy Policy.
How to verify this yourself
You do not have to take our word for it, and checking takes about ten seconds:
- Open your browser’s developer tools (F12 or Ctrl/Cmd + Shift + I).
- In Chrome or Edge, go to Application → Storage; in Firefox, Storage; in Safari, the Storage tab.
- Look at Cookies, Local Storage and Session Storage for this domain. All three will be empty.
- Check the Network tab and filter by domain — the only external hosts you will see are the two Google Fonts domains.
Blocking the font requests
If you would rather your browser made no third-party requests at all, block fonts.googleapis.com and fonts.gstatic.com. Every calculator continues to work exactly as before — the site simply renders in your system fonts.
Changes
If we ever introduce a cookie or any client-side storage, we will update this page and the Privacy Policy before or at the same time as the change goes live, and add a consent mechanism where the law requires one.
