Privacy and fairness
What the tool does
Selections happen locally using the browser Web Crypto API. Visual motion presents an already-selected result and never secretly decides it. Optional saved data remains in this browser until you remove it.
Limitations
Use it for the right job
Not for regulated lotteries, gambling, legal drawings or cryptographic key generation. Decimal output is rounded to the selected precision.
ChoiceDrop does not claim “true random” results, certification or independent auditing.
Frequently asked questions
Good to know
Are both endpoints included?
Yes. Integer minimum and maximum are inclusive; decimal values are generated across the configured interval and formatted to your precision.
Can I exclude a range?
Yes. Add individual values or ranges, then combine them with odd-only or even-only filters.
How are repeat-free results checked?
The tool calculates eligible values and shows an error before selection when the unique request is impossible.
