Frequently asked questions

Are the UUIDs random?

Yes — v4 UUIDs from crypto.randomUUID / getRandomValues, so they're cryptographically random.

Can I remove the dashes?

Yes, and you can uppercase them too.

Is it private?

Every calculation happens on this page, in your own browser. Your input is never sent to a server, never logged and never used for training — which also means the tool keeps working when you are offline.
