A local-first age verification gateway that uses zero-knowledge cryptographic proofs to confirm a user meets an age threshold without transmitting identity documents, biometrics, or personally identifiable information to websites or intermediaries. Users verify once on their own device and receive a reusable, unlinkable credential that sites can validate without learning who the user is.

Age verification mandates are rapidly expanding across multiple countries in 2025-2026, creating urgent consumer demand for compliance tools that don't sacrifice privacy. Growing public backlash and high-profile data breaches from centralized ID-check providers have opened a window for privacy-first alternatives.
