Cookie Policy

Last updated: June 2026

This page explains the cookies and similar technologies used on Test Your Device, why they're here, and how you can control them. The short version: we don't use cookies to track who you are personally, and the tools themselves set nothing. The cookies that exist come from analytics and advertising, and you can switch them off.

What a cookie actually is

A cookie is a small text file a website asks your browser to store. It can hold a setting or an anonymous identifier, and it's sent back to that service on later visits. Cookies can't read other files on your device or access your microphone, camera or keystrokes — they're just small notes. Some related technologies, like the browser's local storage, work similarly.

The tools set no cookies

This is the important part. Running the microphone test, webcam test, keyboard test or any other tool does not set a cookie and does not store your audio, video or input. Everything those tools do happens in your browser's memory and is gone when you close the tab. You could block all cookies entirely and every tool on this site would still work perfectly.

Cookies that are used

Analytics (Google Analytics). We use Google Analytics, loaded through Google Tag Manager, to understand aggregate, anonymous traffic — which tools are popular, roughly where visitors come from, and whether pages load properly. These cookies don't tell us who you are. They help us decide which guides to write next.

Advertising (Google AdSense). The site is funded by ads served through Google AdSense. Google may set cookies to limit how often you see a given ad and, depending on your settings and region, to show more relevant ads. Google's use of advertising cookies is governed by its own policies, and you can review or adjust what Google personalises at My Ad Center.

Essential. A small number of strictly necessary cookies may be used by our host, Cloudflare, to keep the site secure and running. These don't track you across sites.

How to control cookies

You're in control. Every major browser lets you block or delete cookies: in Chrome it's Settings → Privacy and security → Third-party cookies; in Safari it's Settings → Privacy; in Firefox it's Settings → Privacy & Security; in Edge it's Settings → Cookies and site permissions. You can block third-party cookies specifically, which disables the analytics and advertising cookies above while leaving the site fully functional. Browser "private" or "incognito" windows also clear cookies when you close them.

Do Not Track and regional rights

If your browser sends a Global Privacy Control or Do Not Track signal, advertising partners that honour it will adjust accordingly. Depending on where you live — for example, under the GDPR in Europe or the CCPA in California — you may have additional rights over data that advertising partners collect; those are exercised through the relevant provider, and Google's ad settings linked above are the main control.

Changes to this policy

If we add or change a third-party service that uses cookies, we'll update this page and the date above. For the wider picture of how we handle data, see our Privacy Policy, and for the rules of using the site, our Terms of Service.
