Random Number Generator FAQ

Does Random Jar upload my custom input?

No. These tools run in the browser and do not send your lists, names, questions, or generated results to a backend service.

Can I use the result for high-stakes decisions?

No. Random Jar is intended for low-stakes choices, examples, games, and utility tasks, not medical, legal, financial, safety, or security decisions.

Why did I get a different result after clicking again?

Each run requests fresh random values from the browser crypto API, so repeat runs are expected to produce different results.
