ProveOnce

ProveOnce is the privacy-first identity verification app that lets you prove your age or identity to any participating merchant — once — without sharing your personal information.

When a merchant needs to verify your age, you scan their QR code or enter a short code in the app. ProveOnce confirms only what's required (for example, "over 21") and issues a secure, revocable token. The merchant sees a yes or no. They never see your name, date of birth, address, government ID, or selfie. Ever.

Your verified identity is encrypted and stored only on ProveOnce's secure servers — not on your device, not in anyone else's database. You can see exactly who has verified you, and revoke access to any merchant at any time with a single tap.

FEATURES: • One-time ID verification — verify once, use everywhere ProveOnce is accepted • Zero data sharing — merchants receive only a cryptographic yes/no, never your personal data • Instant wallet — see all your active verifications in one place • One-tap revoke — remove merchant access to your verification at any time • Family controls — parents can manage and approve verifications for their children • Push alerts — get notified in real time when your verification is accessed or revoked • Activity log — a complete audit trail of every verification event • Biometric login — Face ID and Touch ID supported

ProveOnce works with online stores, apps, venues, and services that require age or identity verification. Once you're verified, proving eligibility takes seconds — no re-uploading your ID, no typing your birthday, no handing over your data again.

Your data. Your control.
