How the randomness works
Where it matters, these tools use the Web Crypto API built into modern browsers rather than a simple pseudo-random function, so results cannot be predicted from earlier ones. Nothing you generate is sent to us or stored on a server. For a public giveaway, record your screen or share the list and the result so participants can see the draw was fair.
