# A profile's fingerprint

> What Umbreta builds a profile's fingerprint from, why the time zone and language follow the proxy, and what an anti-detect browser can't promise.

After this page you understand what a profile's fingerprint is made of and why sites see it as a separate computer.

## One consistent computer

A fingerprint is put together as one consistent computer, not a set of random values: hardware from a catalogue of real configurations for the chosen system, with Canvas, WebGL, fonts and language to match. User-Agent and client hints come from a real Chrome version.

Every browser build is checked in CreepJS, Pixelscan and BrowserScan.

## Time zone and language

- The **time zone** follows the proxy's IP on every launch: a new exit means a new time zone.
- The **language** is set from the proxy's country when the profile is created. If the exit later turns out to be in another country, the app warns about the mismatch and offers a matching language, one press of **Set …**.

## System

Windows covers most FB traffic, so it is the pick for most work. A macOS profile launches only on a Mac. Linux is rare and suits the cloud.

## A profile's face

Every profile has its own tile, color and platform badge. They show in the window and the taskbar, so profiles never get mixed up.

## What a fingerprint doesn't do

An anti-detect browser removes the browser's technical traces. It doesn't guarantee an account won't be blocked: platforms also look at behavior, creatives and payments.
