What’s the difference between UUID v1 and v4?

UUID v1 includes timestamps and device identifiers; UUID v4 is completely random using cryptographic entropy.

Is UUID generation secure?

Yes, Solite uses browser-based cryptography (window.crypto) ensuring cryptographically strong random values for UUIDs.

Does this tool store my data?

No data is ever uploaded or saved. Everything is generated locally in your browser for total privacy.
