Prove you're 18+ without revealing your birthdate. All computation happens on your device.
Generate a zero-knowledge proof that you're 18+ without revealing your birthdate
Only dates in the past are accepted
Privacy Notice: Your birthdate never leaves your device. The proof is generated locally and only a cryptographic commitment is sent to the server.
You generate a cryptographic proof that you're 18 or older, all computed locally on your device.
Your actual birthdate never leaves your device. Only a cryptographic commitment is sent to the server.
SHA-256 hashing makes it cryptographically impossible to reverse-engineer your birthdate from the proof.
