A different computer for every Account
Each Account presents its own coherent device — and looks like the same one on every visit.
A fingerprint is the set of readings a site takes to recognise a machine: its screen, graphics, fonts, clock and dozens more. Umbra sets them together, from real devices, so they agree with each other and with the proxy behind them.

Set together, not one by one
Screen, GPU, canvas, audio and fonts come from one real device, so nothing contradicts anything else.
Follows the proxy
Time zone, locale and location track the exit IP — the clock matches the country the Account appears to browse from.
Host tells replaced
Battery, storage estimate and installed voices are rewritten, so the shared machine underneath never shows through.
Stable across visits
The same Account reads the same way on every visit. Consistency is what a real returning user looks like.
Where do the fingerprints come from?
Real device fingerprints, not random values — so the combination is one a site has actually seen before.
Can I pin specific values?
Yes. Set a value by hand and it holds; leave it and Umbra rolls a coherent one.
