Terms and Conditions

LAST UPDATED: JUNE 2026

These terms cover what you can expect from Mouse Tester and what we expect from you. There is nothing unusual here. The tool is free, it runs in your browser, and these terms exist to make the relationship clear on both sides.

By using this site, you agree to what is written below. If something does not seem right, stop using the site and contact us at the address at the bottom of this page.

Who These Terms Apply To

These terms apply to anyone who visits our site, whether you are here to check a new mouse, diagnose a double-click issue, or just browsing. You do not need to create an account or sign up for anything. Using the site means you have accepted these terms.

If you are using the site on behalf of a company or organization, you are agreeing to these terms on their behalf as well.

What Mouse Tester Actually Is

Mouse Tester is a free, browser-based diagnostic tool. It captures mouse button clicks, scroll wheel input, and side button presses directly in your browser and shows you whether each input is registering correctly.

The tool does not connect to your hardware at a driver level. It reads input events your operating system sends to the browser, the same signals every website receives when you click or scroll. Nothing about the tool requires special permissions, software installs, or elevated access on your device.

The site also publishes supporting content explaining how to interpret test results, what common mouse faults look like, and how different mouse specs affect performance. That content is there to help you, not to sell you anything.

Permitted Use

You are welcome to use Mouse Tester for personal diagnostic purposes, checking your own mouse, helping someone else check theirs, or running tests out of curiosity. That is what the tool is for.

What You Should Not Do

A few things are off the table:

None of that should come as a surprise. These are standard restrictions any reasonable site would put in writing.

Linking to Mouse Tester

You are free to link to any page on this site. No permission needed. If you want to reference a specific test or page in an article or forum post, go ahead. We just ask that you do not frame the site inside another website in a way that makes it look like your own tool.

The Tool Is Provided As-Is

Mouse Tester works in modern browsers on Windows, Mac, and Linux. It has been tested across common browsers and devices. That said, we cannot guarantee it will work perfectly in every environment, on every browser version, or with every mouse model.

The tool gives you accurate information about what your browser is receiving. What your browser receives depends on your operating system, drivers, and hardware. If the test result seems off, there may be a layer between the hardware and the browser that the tool cannot reach.

We do not make any promise that the tool will diagnose every mouse fault. It catches a wide range of common problems, double-clicking, scroll wheel misfires, missed button inputs, but hardware failures at the driver or firmware level may not surface in a browser test.

No Warranty on Test Results

The results you see in the tool reflect what your browser recorded during your session. They are not a certified hardware diagnosis. If you use this information to decide whether to replace or repair a mouse, that decision is yours to make. We are not responsible for outcomes based on how you interpret the results.

This is not us trying to avoid responsibility. It is an honest acknowledgment that a browser tool has real limits, and you should factor that in.

Advertising on This Site

Mouse Tester is free to use. It is supported by advertising. We use Google AdSense to serve ads, which means ads on this site may be personalized based on your browsing history across other sites.

We have no control over which specific ads appear. We do not endorse any product or service advertised on this site just because an ad appeared here. The ads are served algorithmically by Google based on available inventory and your browsing profile.

If you ever see an ad that seems misleading, harmful, or out of place, you can report it directly to Google. We also want to know — contact us at the address below.

For details on how advertising data is handled, the data practices behind the ads shown on this site are covered in our privacy policy, which explains what Google AdSense collects and how you can opt out of personalized ads.

Intellectual Property

The written content on this site, the explanations, test guides, benchmark tables, and supporting articles belong to Mouse Tester. You are welcome to quote short passages with attribution and a link back to the source page. Reproducing entire sections or pages without permission is not allowed.

The mouse testing tool itself, the code that captures and displays input events, is the property of Mouse Tester. You may not copy, modify, or redistribute it.

Third-Party Content

Some pages reference external sources, research, and community discussions. Those belong to their respective owners. We link to them fairly and do not claim them as our own.

If you believe something on this site infringes on your intellectual property, contact us, and we will look into it promptly.

Limitation of Liability

Mouse Tester is a free diagnostic tool. It does not charge you money, collect your personal data, or ask anything of you beyond the time it takes to run a test.

Given that, our liability is limited. We are not responsible for:

If something on this site causes you a problem, tell us. We want to fix genuine issues. But we cannot accept liability for outcomes outside our control.

External Links

Some pages on this site link to external resources, browser settings pages, third-party tools, community discussions, or product information. These links exist because they are useful, not because we have a relationship with the people running those sites.

We do not control external sites and cannot vouch for their accuracy, safety, or availability. Following an external link means you are leaving Mouse Tester and entering a space governed by someone else's terms.

Changes to These Terms

We may update these terms from time to time. The "last updated" date at the top of this page changes whenever we do. Minor updates, fixing wording, and adding a clarification will not be announced individually. Significant changes will be noted clearly on the site.

Continuing to use Mouse Tester after a change means you accept the updated terms. If you disagree with a change, stop using the site and let us know why.

Governing Law

These terms are governed by the laws of the United Kingdom. If any part of them turns out to be unenforceable, the rest still applies. The unenforceable part would be replaced with the closest enforceable equivalent.

If you have a dispute about these terms or about how the site operates, we would rather resolve it directly. Contact us first before taking any formal steps.
