ZeroClick Age
A privacy-preserving age-verification service that lets a website confirm a visitor is 18+ without ever learning who they are, using device attestation and zero-knowledge proofs — so age-gated sites can comply with the EU rules this initiative targets without handing users a digital ID.
Adult-content publishers and age-gated product sites in the EU and UK
- One-tap age attestation via a partner bank, mobile carrier, or government eID — site only gets a yes/no token
- Zero-knowledge mode: the verifier learns the user is over 18 but nothing else (no name, no email, no device ID)
- Site-side drop-in widget with Stripe-style checkout integration for compliance teams
- Compliance dashboard showing audit trails, regulator-ready proof of privacy guarantees
A EU Citizens' Initiative trending with 141 HN points shows massive public pushback against mandatory digital ID — publishers need a way to meet age-gating rules without becoming the surveillance target users are rejecting.
EU released a white-label age-verification blueprint on 14 July 2025 and UK Ofcom requires 'highly effective age assurance' for porn sites from 25 July 2025; ZKP market projected 22.1% CAGR to $7.6B by 2033 — real regulatory deadlines driving publisher demand.Commission makes available an age-verification blueprint ↗Age Assurance: Pornography sites required to employ measures from 25 July 2025 ↗

Underlying laws (UK OSA 2023, EU age-verification roadmap, member-state pilots) are multi-year regulatory regimes with enforcement teeth; ZKP market forecast 22% CAGR through 2033 supports long-tail demand, though EU centralization risk is real.Zero Knowledge Proof Market Size Report, 2025-2033 - Grand View Research ↗The EU approach to age verification ↗
Brave Research (Nov 2025) explicitly flags that many ZKP age-verification proposals are fragile, lack soundness, leak via age-range tiers, and that credential-based systems risk exclusion and new centralization — device attestation also depends on Apple/Google gatekeepers, making this non-trivial to build correctly.The limits of zero-knowledge for age-verification | Brave ↗
