常见问题
How is the pick chosen?
Each item has exactly equal probability. We pick a uniformly-random index using the Web Crypto API (crypto.getRandomValues) with rejection sampling, so there's no modulo bias.
Can it avoid repeats?
Turn on "No repeats" in Options and previously-picked items will be skipped until you reset, which is great for working through a list one winner at a time.
Does my list get sent anywhere?
No. Everything runs entirely in your browser, your list is never uploaded, and the tool keeps working even offline.
