Privacy

The short version: no account, no cookies, no tracking. We never store your full IP address, and test results are deleted after 180 days.

What the test does

Your browser sends small test requests to our servers to measure response time, lost data and how website lookups (DNS) are handled. If you choose the speed test, your browser also downloads and uploads data to a Measurement Lab server for about 20 seconds.

What we store

• Your test results: the measurements and our diagnosis.
• The problem you selected, such as "Gaming is lagging".
• A shortened version of your IP address (for example 203.0.113.0 instead of 203.0.113.57), which covers about 250 addresses rather than identifying one connection.
• Your Internet provider and approximate city, looked up from your IP address using an offline database (MaxMind GeoLite2). The lookup happens on our server; your address isn't sent anywhere for it.
• For the DNS test: which organization runs your DNS service (for example "Your Internet provider's DNS"), never the DNS server's address.

What we don't store

• Your full IP address.
• Your name, email or any account, because there isn't one.
• Cookies. Your browser remembers only whether you ticked the speed-test box, and that stays on your device.
• Anything about other websites you visit.

Speed test (Measurement Lab)

The speed test is optional and runs on servers from Measurement Lab (M-Lab), a research consortium. M-Lab publishes every speed test, including your IP address, as open research data (M-Lab privacy policy). That's why the test asks before running it. Without it, every other test still runs.

Your results link and share links

Your results page has a long, random address. Anyone with that address can see your results, including your provider and approximate city, so keep it to yourself or people you'd share results with anyway.

If you create a share link, it shows only the headline, the health score and a few measurements: no provider, no location and no test ID. Share links stop working when the results are deleted.

Comparison codes for a second device expire after 30 minutes.

How we count visits

To see whether the site is useful, our server counts things as daily totals, such as "120 tests completed today" or "40 visits to the Wi-Fi guide." Each count is just a date and the name of what happened. It's never linked to you, your IP address or your test.

We also count which website sent a visit (for example "google.com"), by site name only, never the full page address. There's no tracking script, no cookie, and no analytics company involved. Daily totals are kept for about a year.

How long we keep it

Test results are deleted automatically after 180 days.

Each night we add the day's tests to anonymous totals per Internet provider, for example how many tests had a response time between 20 and 30 ms in the evening. These totals hold no IP address, location or individual result, and they're kept after the tests themselves are deleted. Provider pages show numbers only once at least 30 tests have been combined, and tests made through a VPN are left out.

Third parties

• Measurement Lab, only if you choose the speed test (see above).
• Product links. Some results suggest a type of product, with an affiliate link. We count clicks on those links as daily totals only. Once you're on the retailer's site, their privacy policy applies. See our affiliate disclosure.
• No advertising networks, third-party analytics or social media scripts run on this site.
