❓ Frequently asked questions

How random are the values?▼
They use crypto.getRandomValues / crypto.randomUUID — the browser's cryptographically secure randomness.

No. Everything is generated locally and never stored or sent anywhere.
What are UUIDs for?▼
Unique IDs for records, files or API-key building blocks — practically always collision-free.
