Privacy

No account, no tracking, and no advertising cookies. Your results stay in your own browser; a copy of the measurements, carrying nothing that identifies you, is sent here so the rating scale can be calibrated against real devices.

Stored in your browser

Three things, all in this site's own localStorage, all readable only by this site and only on this device. Clearing your browser's site data removes every one of them.

• The device type you chose - phone, tablet, laptop or desktop. Written only when you tap one of the buttons. The detector's guess is never saved, because a guess is not a statement of fact and should not outlive the visit.
• Your completed runs, up to the last eight, so the comparison table has something to compare. These never leave your browser unless you copy a share link yourself - and a share link carries the measurements inside the link itself, not a key to a row on any server.
• Whether you turned off contributing results, so the choice survives a reload.

Sent to this site's server

When a run finishes, unless you have turned it off, these are posted and kept:

• the measurements - overall score, CPU score, average FPS, 1% low FPS, frame consistency, refresh rate and core count;
• the device type you chose;
• a coarse operating system name - one of Windows, macOS, Android, iOS or Linux, and nothing more specific;
• what the device detector guessed, how confident it was, and whether you corrected it;
• the measured core structure - the fastest worker's throughput and the spread between the fastest and slowest. These describe how the processor is built, not who owns it.

That last one exists so the detector can be judged on its record rather than on anyone's opinion of it. If it turns out to guess wrong often, it gets deleted.

The stored row has 15 columns and none of them identifies anybody: no name, no account, no device identifier, no advertising identifier, no cookie, no browser user-agent string, no graphics-card string, and no IP address. There is no column for any of those, so there is nothing to disclose, leak or hand over. That count is read from the schema itself when this page is built, so it cannot drift from the table it describes.

Your IP address is seen by the server, as it is by every website you visit. It is held in memory only to cap how many runs one address can submit in an hour, it is never written to disk, and it is gone when the server restarts.

Why collect anything at all? The tier - Flagship, Mid-Range, Entry-Level - currently rests on an estimate of what a strong device of each type scores. Once enough real runs of a device type exist, that estimate is replaced by where your device actually falls among them, and the guesswork disappears. That is the only thing this data is for. It is not sold, shared or used to build a profile, because there is nothing in it to build a profile from.

Sent to Google

The same measurements are sent to Google's Gemini API, which writes the plain-English summary shown under your results. That summary is part of what the test produces, so the request happens as part of running it. Nothing identifying accompanies it - Google receives the numbers and the device type, the same as the list above, and no more.

Advertising

No ads are served today and no advertising cookie is set. The panel on the results screen marked "Advertisement" is an empty placeholder.

If advertising is enabled later it will be Google AdSense, and visitors in the EEA and the UK will be shown Google's own certified consent message before any advertising cookie is set. That mechanism is operated by Google, not by this site; this site has no means of setting an advertising cookie on its own and does not.

What this site does not do

• No analytics of any kind - no page-view counter, no session recording, no heatmap.
• No third-party scripts, fonts, or images. These pages load nothing from any other host.
• No email address is collected, because there is nowhere to enter one.
• No cross-site tracking, and nothing that could support it.
