NEW RELEASE - APRIL 2026
Private Age
Verification,
Now on iPhone
Prove you're over 18 in Safari or Chrome — without sharing any personal data. Tracking is structurally impossible: nothing leaves the device.
Zero-Knowledge Proof (ZKP) age verification, running natively in Safari and Chrome, both on iOS and Android.
WHY THIS MATTERS
The problem with age verification today
01
Current checks expose everything
Scanning a driving licence hands over your full name, home address, date of birth, and document number — all to answer a single yes/no question. That data gets stored, often indefinitely.
02
ZKP answers the question — nothing else
Zero-Knowledge Proof cryptography lets a user prove a statement ("I am over 18") is true without revealing the underlying data. The verifier receives a yes or no. That's all.
03
Works on the device everyone already has
Scytáles brings ZKP age verification to both major mobile platforms — available free on the App Store and Google Play, running natively in Safari and Chrome without additional configuration.
THE USER FLOW
Five steps. One result.
Zero data leaked.
1

In Safari or Chrome on iPhone and Android. No app switch, no special setup.
2
Verification request issued
Site sends a ZKP challenge via standard browser API.
3
Scytáles Wallet activates
User selects their mDL credential. Multi-wallet selection supported.
4
Proof generated on-device
Cryptographic proof created locally. No data transmitted to any server.
5
Verifier receives: ✓ Over 18
A single boolean confirmation. Nothing more is shared.
TECHNICAL DEPTH
Built for the standards community
mDL compliance & multi-wallet support
Scytáles implements the ISO 18013-5 mobile Driving License standard and is designed for real-world deployment conditions — including scenarios where a user holds mDL credentials across multiple wallets simultaneously.
The multi-wallet flow uses a "best-effort" device engagement approach optimised for iOS constraints, ensuring the user is always presented with their Scytáles credential as an explicit, informed choice — not an invisible background selection.
Single-attestation flows are also fully supported, covering the majority of production relying-party deployments today.
