Frequently Asked Questions
Does this tool store or track my device information?
No. Everything shown in the tool is read by JavaScript running in your own browser and displayed back to you on the page. We don't send it to a server, log it, or save it anywhere on our end. The only outside call the page makes is a request to a public IP lookup service so it can show you your own IP address. See the Privacy Policy for more on that and on the analytics this site uses.
Why does my browser show up as "Chrome" when I'm using Edge, Opera, or another browser?
Most non-Safari, non-Firefox browsers on desktop and mobile are built on the same underlying
engine as Chrome (Chromium), so their user agent strings include a Chrome version token alongside
their own. This tool checks for browser-specific markers first (Edge's Edg/, Opera's
OPR/) before falling back to the generic Chrome token, but user agent strings aren't
standardized, so occasional misidentification on less common browsers is possible.
What is a "user agent string," and can it be wrong?
The user agent is a short line of text your browser sends with every request, historically used to describe the browser, rendering engine, and operating system making the request. It can be inaccurate for two reasons: some browsers deliberately include legacy tokens for compatibility with older websites, and any browser can be configured, via developer tools or extensions, to send a different user agent than its real one. Treat it as a strong hint, not a guarantee.
Why are my Screen Resolution and Viewport Size different numbers?
Screen Resolution is the full size of your physical display. Viewport Size is the space actually available to the web page inside your browser window, which excludes things like the browser's toolbar, tabs, bookmarks bar, and any window borders or space taken up by other windows on your screen. On a maximized browser window the two will be close; in a smaller or split window, Viewport Size will be noticeably smaller.
What does Device Pixel Ratio actually mean?
It's the ratio between physical screen pixels and CSS pixels. A ratio of 1 means one physical pixel per CSS pixel — typical of older or lower-density monitors. A ratio of 2 or 3, common on phones and high-density laptop displays, means the screen packs multiple physical pixels into each CSS pixel to render sharper text and images.
Is the Public IP Address shown here accurate, and will a VPN change it?
The IP address shown is whatever address your connection currently presents to the public internet, as reported by a third-party lookup service. If you connect through a VPN, proxy, or your mobile carrier's network, this is the address those services expose — not necessarily the address assigned directly to your home router. That makes this page a reasonably quick way to confirm whether a VPN connection is actually active: the address should change once you connect.
Why do CPU Cores or Device Memory sometimes show "Unavailable"?
Not every browser exposes these values. Safari, for example, does not support the Device Memory API at all, and some browsers cap or omit the hardware concurrency figure for privacy reasons. When a browser doesn't provide a value, this tool shows "Unavailable" rather than guessing.
Is this a device fingerprinting or tracking tool?
No. Fingerprinting techniques combine many small signals, often invisibly, to try to re-identify a visitor across sites and sessions without their knowledge. This tool does the opposite: it reads a handful of standard, visible browser properties and displays them openly, once, for you to look at and decide what to do with. Nothing is combined into a persistent identifier or shared with third parties for tracking purposes.
Does this site use cookies or analytics?
Yes. The site uses Google Analytics to understand overall traffic, and it uses your browser's local storage to remember your dark mode preference between visits. Full details, including any third-party services and future advertising cookies, are in the Privacy Policy.
