Frequently asked questions
What kind of UUIDs are these?
They are random RFC 4122 version 4 UUIDs, the most common type, generated with the browser’s secure crypto random source.
Are the UUIDs unique?
Version 4 UUIDs are random 122-bit values, so the chance of a collision is astronomically small for any realistic use.
Is anything uploaded?
No. UUIDs are generated entirely in your browser; nothing leaves your device.
