About ReadMyBrowser

Why this exists

Most people have no idea how much a website learns the instant a page loads. Your IP address, your browser and version, your operating system, your screen size, your timezone, your language, even your graphics hardware are all handed over automatically, with no prompt. A handful of those facts, combined, can single out your browser without a single cookie.

ReadMyBrowser lays all of it out plainly, in one calm dashboard, and explains each item in language a non-specialist can follow. The goal is not to alarm you but to make the invisible visible. Once you can see a signal, you can decide whether to change it, mask it, or leave it be.

How it works

Everything runs in your browser. The detection uses standard web APIs that any site could use, so what you see here is genuinely what any site could learn. The only network calls are a first-party IP echo (the kind every "what is my IP" tool needs) and, only if you explicitly allow location, a reverse-geocoding lookup relayed to the public OpenStreetMap Nominatim service to turn coordinates into a zip code or address. We never log or store your coordinates.

There are no accounts and nothing you type is stored, because nothing needs to be: the detection itself happens entirely in your browser. That client-side design is a deliberate choice for a tool about privacy. There is no analytics on this site, no advertising and no third-party script of any kind; the privacy policy spells out exactly what that means and what it costs us.

Who it is for

Anyone curious about what they share online, privacy-conscious readers who want to reduce their footprint, and developers who need a quick, honest reference for what browsers expose. If you build things for the web, the free API and the user agent parser are for you.

Accuracy and honesty

Where a value is an estimate rather than a reading, we say so on the page itself. IP-based location is a lookup, not a measurement. The fingerprint entropy figures are our own reasoning, not population statistics, because measuring how rare your browser really is would mean collecting fingerprints, which we will not do. The methodology page draws that line explicitly and shows every figure.

Every signal page carries the date a human last checked its facts, and corrections are listed on the changelog as corrections rather than folded quietly into a release note. If you spot something wrong or out of date, please get in touch; a real person reads what comes in.

Who builds it, and why it is free

FusionStudios builds websites and web applications for clients. Tools like this one are how the studio shows what it can do, which is more convincing than a page of adjectives. That is the whole commercial motive, and it is worth stating plainly rather than leaving you to wonder what the catch is on a free privacy tool.

It also explains why there is no advertising here and never will be while the site says what it says. A page explaining how tracking scripts work, that loads a tracking script to pay for itself, is not worth publishing. What FusionStudios builds is one click away if you need something similar, and nowhere else on the site.
