No — it uses Math.random(), fine for games, raffles, sampling, and testing. For passwords, tokens, or anything adversarial, use the Password Generator (Web Crypto) instead.
Unique mode shuffles the full range and slices the count — guaranteed unique draws within the range. Requesting more than the range returns the whole range instead of looping.
Integers only: set any min/max range for dice, draws, and IDs. For decimals, scale integers (e.g. 1–1000 ÷ 100) in your own sheet.
No. Generation runs entirely in your browser. Nothing leaves your device.
Requesting 10 unique numbers from 1-5 returns the full 5-number pool instead of erroring or looping. The count field accepts 1-10,000; the Lottery preset (1-49, 6 unique) shows the classic use.
