Questions
Are the numbers truly random?
They come from your browser's cryptographic random generator (crypto.getRandomValues), the same source used for passwords, so every number in the range is equally likely.
Can I use it for a lucky draw?
Yes. Number the entries, set the range and pick with “No repeats” on. Press Generate again in front of everyone for transparency.
Are the minimum and maximum included?
Yes. Both ends of the range can be picked.
