Comprobación de huella del navegadorMira qué le cuenta este navegador a cada sitio que abres: pantalla, tarjeta gráfica, fuentes, reloj, idioma y los valores con los que te reconocen.
Prueba de fuga de WebRTCMira qué direcciones entrega este navegador a cualquier sitio por WebRTC, sin preguntarte.
Audio fingerprintA site runs a tone through a compressor with no speaker output and sums the samples. The sum is the audio fingerprint, and here yours is shown together with whether it repeats.
Canvas fingerprintA site asks the browser to draw a picture and folds its bytes into a number. That number is the canvas fingerprint, and here yours is shown together with whether it repeats from one read to the next.
Connection fields checkA browser describes the connection with a few numbers: latency, speed and kind. On a phone they are joined by fields a desktop lacks, and here you see what your browser hands over.
Fonts and generic familiesA site learns which fonts you have by measuring the width of a string, and separately asks for six generic families. Here both answers are shown the way a site sees them.
Hardware and client hintsThe number of cores, the memory size, touch points and client hints are read by a site in the first second and compared with each other. Here you see what it gets from your machine.
Screen and window checkA site reads the screen size and the window size as two plain numbers and compares them. A window wider than the declared screen describes a machine that does not exist, and this check shows both pairs the way a site sees them.
Clock and language checkThe timezone, clock offset, language list and calendar settings are read by a site without permission and compared with the country of your address. Here you see exactly what it gets.
Graphics card and WebGLA site gets the graphics card name as a ready string and computes the WebGL picture itself. Here you see the string, the number from the picture, and whether the browser has a WebGPU road.
