Coin Flip 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.
