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
Short batches often look uneven by chance. Results are for everyday and educational use, not wagering.
ChoiceDrop does not claim “true random” results, certification or independent auditing.
