Cookies and local storage
Last updated: June 2026
National Calculators is built to stay light. Every calculation runs in your browser, so the numbers you type are never sent to a server. The small amount of data the site needs is kept on your own device in local storage, not in tracking cookies.
What we store
These values remember your choices. None of them identify you, and none are shared with anyone.
| What | Why | Type | Kept for |
|---|---|---|---|
| Country preference | Remembers the country version you last used, so you land on the right calculators next time. | Local storage | Until you clear it |
| Language preference | Keeps the site in the language you picked. | Local storage | Until you clear it |
| Cookie notice flag | Records that you have seen the cookie notice so it does not show again. | Local storage | Until you clear it |
| Location hint dismissed | Remembers that you closed the country suggestion on the home page. | Local storage | Until you clear it |
Advertising
We do not run advertising right now, so no advertising or third-party tracking cookies are set. If that ever changes, this page will be updated before any ad code goes live, and you will be able to set your preferences first.
Analytics
We use privacy-friendly, aggregate analytics to count visits and see which calculators people find useful. It does not build a profile of you or follow you across other websites.
We use Google Analytics in consent mode. Until you accept analytics, it sets no cookies and stores no identifiers on your device; only anonymous, cookieless signals are sent. If you accept, analytics cookies are enabled to count visits more accurately. Choosing "Essentials only" keeps everything cookieless, and you can change your mind any time via "Cookie settings" in the footer.
How to clear what we store
You can remove everything National Calculators has saved at any time. Clear the site data for this domain in your browser settings, usually under Privacy or Site settings. That simply resets your country, language and notice choices.
