Frequently asked questions
Does my data leave the computer?
No. The whole analysis runs in your browser. We send and store nothing.
Can you see my disk (SSD/HDD) speed?
Not directly — the browser has no access to the disk. We measure the browser's own read and write speed, which is an approximation, and show the space the browser has available, not the disk's.
Why do some lines say "not detectable"?
For privacy, some browsers hide data such as the graphics card model or total memory. When we can't read it reliably, we say so instead of guessing.
Is the verdict a definitive diagnosis?
It is guidance based on what the browser can read. A full diagnosis needs the system's native tools.
