FAQ
What is the difference between UUID v4 and v7?
v4 is random. v7 includes a timestamp component, so values are roughly ordered by generation time.
Can UUIDs collide?
In theory yes, but collision probability is extremely low for UUID v4.
Is my data sent to a server?
No. Everything runs locally in your browser and nothing is uploaded.
