Cookie Policy
What gets left on your device
Last updated: July 2026.
Cookies and similar technologies — like your browser's local storage — let a website remember things between visits. ExpireOnDate keeps them to a bare minimum. The calculator itself sets none: every answer you give is processed on your own device and disappears when you close the tab.
Strictly necessary (always on)
A small amount of on-device storage remembers your cookie choice and, where relevant, your progress through the questions. It never leaves your device and is never sent to one of our servers. The site can't work sensibly without it, so it stays on.
Advertising
Ads on this site are served by third-party advertising partners, which may set cookies to display and measure ads and to show ads based on your visits to this and other sites. If you are in the EEA or UK, a certified consent tool asks for your choice about ad personalisation, and personalised ads are only shown with your consent; without it you may still see non-personalised ads. You can review how Google uses cookies in advertising and opt out via Google Ads Settings.
Analytics
We do not currently run third-party analytics or tracking pixels. If that ever changes, we'll update this policy and ask for consent where the law requires it.
Managing your choices
You're in control. Open Cookie Settings at any time to review or change your choices and to clear anything stored. You can also clear cookies and local storage through your browser's settings, and most browsers let you block cookies entirely.
