Frequently Asked Questions
How are the random numbers generated?
This tool utilizes standard JavaScript pseudo-random number generation (Math.random()) to quickly calculate values within your specified constraints.
Why did it stop generating unique numbers?
If you request more unique numbers than mathematically possible within your defined minimum and maximum range (e.g., asking for 50 unique numbers between 1 and 10), the generator will safely stop once all possibilities are exhausted.
Does this tool save or store my generated data?
No. Because this utility relies entirely on client-side JavaScript, your output remains stored solely in your device's active memory and is permanently erased the moment you close or refresh the tab.
