How it works
Numbers are generated with crypto.getRandomValues(), the browser’s cryptographically secure random generator, not Math.random(). The "no repeats" option shuffles the full range (Fisher-Yates algorithm) and takes the first N; "sort" presents them smallest to largest. Everything happens locally on your device.
