Private health verification.
Zero-knowledge sharing.
ClearCheck empowers you to certify and share your health status without ever compromising your privacy. No servers. No databases. Just trust.
Advanced technology for ultimate peace of mind.
ClearCheck utilizes on-device intelligence and cryptographic proofs to certify health status without ever compromising your anonymity.
Passport Verification
Verify your identity using government-grade NFC ePassport scanning. We confirm you are a real person without ever seeing your ID image.
On-Device OCR
Our AI parses your lab results locally on your phone. Sensitive medical data never touches a central server.
Zero-Knowledge
Your results are encrypted with keys held only by you. We cannot leak what we do not have.
Secure Handshake
Share your status via a dynamic 60-second QR code. Peer-to-peer verification ensures your data stays between you and your partner.
Privacy by design,
not by promise.
ClearCheck is source-available and built using native Swift technology. We invite security researchers to verify that no health data is ever sent to our servers. Our zero-knowledge claims are mathematically sound and publicly auditable.
