Do You Use Cookies?
We use one session cookie for account logins and one temporary cookie for anonymous test sessions. That's it — no advertising cookies, no cross-site tracking, no third-party behavioural data collection.
Cookies we use
| Cookie | Type | Purpose | Expiry |
|---|---|---|---|
| session | Strictly necessary | Keeps you logged in to your account | 30 days (or end of browser session if "remember me" is not checked) |
| anon_session | Strictly necessary | Associates anonymous test results with your current browser session so you can see them after the test completes | End of browser session (deleted when you close the browser) |
What we do not use
- Advertising cookies — we do not use Google Ads, Meta Pixel, or any other advertising network that sets tracking cookies
- Analytics cookies — we do not use Google Analytics, Mixpanel, or similar behavioural analytics platforms that track you across sessions or sites
- Third-party tracking pixels — no invisible 1×1 images from third parties that phone home when you visit a page
- Cross-site tracking — our cookies are scoped to speedtest.now and are not readable by any third-party domain
What each cookie contains
Session cookie (logged-in users)
The session cookie is a signed, encrypted token that contains your user ID and session metadata. It does not contain your email address, password, or any personal data in readable form. The token is signed with a server-side secret key, so it cannot be forged or tampered with by a client.
Anonymous session cookie
The anonymous session cookie is a random UUID generated when you run your first test without an account. It is used only to associate your test results with the current browser session so you can view them after the test. When you close your browser, this cookie is deleted. We do not attempt to re-identify you across sessions using this cookie.
Can I disable cookies?
Yes. Both cookies are strictly necessary for the functionality they support — disabling them has the following effects:
- If you block the session cookie: you will not be able to stay logged in. You can still run tests anonymously.
- If you block the anonymous session cookie: you can still run tests, but the results page may not display correctly immediately after the test completes, as we use this cookie to retrieve the result for display.
You can manage cookie preferences in your browser's privacy settings. As we do not use non-essential cookies, there is no cookie consent banner — the only cookies we set are required for the site to function.
Local storage
In addition to cookies, Speedtest.now uses browser local storage to cache your most recent test result for display on the results page. Local storage data never leaves your device and is not transmitted to our servers. It is cleared when you clear your browser's site data.
