Terms of use

Terms of use

Plain-language terms. They describe how the site actually behaves rather than making claims it cannot support.

Using this site

By using Internet Speed Tester (internet-speed-tester.net) you accept these terms. If you do not, please do not use the site. There is no account to create and no contract to sign — using the pages is the whole of it.

The site is free to use for personal and commercial decision-making. You do not pay for it and it does not pay you.

What the measurements mean — and what they do not

A speed test measures the path between your device and a particular measurement endpoint at a particular moment. That is all it measures. It is not a statement about your internet plan, your ISP's performance in general, or what any other application will experience.

  • Results vary with Wi-Fi conditions, device load, other traffic on the network, the route to the endpoint, and time of day.
  • Figures are estimates derived from sampled transfers. They are not laboratory measurements and no accuracy figure is claimed.
  • Some metrics cannot be measured in a browser at all. Where that is true, the page says so rather than substituting a different number: this applies to UDP packet loss and to in-game server latency.
  • A result is not evidence of a fault, and is not a substitute for diagnostics performed by your network operator.

Acceptable use

Please do not:

  • use automated scripts to run measurements continuously or at volume — a speed test transfers real data and costs real bandwidth;
  • use the site to load-test or stress a network, including your own, in a way that affects other people;
  • attempt to interfere with the site, the measurement endpoints, or other users' access to them;
  • present results generated by this site as an official certification of any network's performance.

Access may be limited or blocked where traffic is clearly abusive. Since the site has no accounts, this is done at the network level rather than per user.

Third-party measurement endpoints

Measurements are carried out against endpoints operated by third parties, by default speed.cloudflare.com. Those requests are subject to the operator's terms and privacy policy as well as ours, and their availability is outside our control.

If this deployment is configured to use a self-hosted measurement backend instead, that operator's terms apply.

Content, and no professional advice

The written guidance on this site is general information about how networks behave. It is not professional, legal, or telecommunications-engineering advice, and it cannot account for the specifics of your premises or contract.

You are welcome to quote or link to the site with attribution. Do not reproduce substantial parts of it as your own work.

No warranty, and limits on liability

The site is provided "as is". It is offered without warranties of any kind, including that it will be available, uninterrupted, error-free, or that any measurement will be accurate for your purposes.

To the extent permitted by applicable law, no liability is accepted for any loss arising from use of the site or reliance on a measurement — including decisions about purchasing, cancelling or upgrading a service. Nothing in these terms excludes liability that cannot lawfully be excluded.

Privacy

What is stored on your device, and what is sent to the measurement endpoint, is described in the privacy notice. There are no accounts, no advertising scripts and no server-side storage of individual results.

Changes

These terms may change as the site develops. The current version is always this page, and material changes will be dated here. Continuing to use the site after a change means you accept the revised version.

Last reviewed: October 2026. This is a plain-language document, not a lawyer-reviewed contract. It should be reviewed professionally before the site is used commercially at scale.

Questions

Is using the site really free?
Yes. There is no account, no paid tier and no requirement to provide personal details.
Can I use a result in a complaint to my ISP?
You can, and the share link makes it easy to include one. Be aware that an ISP will usually want their own line test as well, because a browser measurement cannot isolate the fault to their network.
Do these terms apply to the measurement endpoint?
No. Requests to a third-party endpoint are governed by that operator's terms and privacy policy in addition to these.
