Is my data sent anywhere?
No. UUIDs are generated entirely in your browser using the native Web Crypto API. Nothing leaves your device.
What is the difference between v4 and v7?
UUID v4 is fully random. UUID v7 encodes the current timestamp in the first bytes, so values are roughly time-ordered, which can improve database index locality.
