Frequently asked questions
Is the randomness cryptographic?
Yes — the generator uses window.crypto.getRandomValues, the same source used by password managers.
Does it work offline?
The calculation runs entirely in your browser, so after the first load it works even with a spotty connection.
Is my data private?
Nothing you enter leaves your device. There is no server round-trip and nothing is logged.
Can I use it on mobile?
Yes — the tool is fully responsive on phones, tablets, and desktops.
