About generating random numbers locally
Random Number Generator draws integers (or the range you set) using Web Crypto in this browser. Pick a minimum, maximum, and how many values. The list appears in the tab. Nothing is uploaded. This is for raffles, sampling, and test data — not for lotteries that need a published seed, not for cryptography keys, and not for scientific Monte Carlo with a documented PRNG.
Inclusive bounds follow the panel. Duplicates may appear unless you asked for a draw without replacement (if the control is present). Do not use this as a password. Password Generator is the sibling for secrets. Dice Roller is the sibling when the metaphor is dice, not a numeric range.
