Checkify

Your data back in your hands

On your device. Not on our servers. Shared only with your consent.

Checkify helps businesses verify what matters without becoming data vaults. Users stay in control, approve every request, and share only what is needed.

For users

Keep your identity on your device and approve exactly what gets shared.

For businesses

Verify age, identity, or human presence without storing unnecessary data.

For both

Clear, consent-based, audit-ready verification built for modern trust.

The problem

Digital verification is broken. Businesses often need to verify identity, age, or eligibility, but doing so usually means collecting and storing sensitive personal data. That creates security risk, compliance burden, and poor user experience.

Our solution

Checkify enables consent-based verification and selective sharing, so businesses can request the proof they need without holding raw personal data long term. Users stay in control. Businesses get fast, reliable decisions.

Why Checkify

Most verification systems collect too much data, keep it too long, and turn every business into a data liability.

Less data exposure

Verify what matters without storing passports, selfies, or unnecessary personal details on central servers.

User-controlled sharing

Every request is reviewed by the user. Nothing is shared automatically, and consent stays central to the experience.

Reusable verification

Verify once, then reuse trusted proofs across websites, apps, and real-world QR flows.

Built for real verification needs

Checkify fits anywhere a business needs confidence without becoming a data vault.

Age checks

Verify “over 18” or other age thresholds without collecting full identity documents.

Human verification

Replace friction-heavy CAPTCHA flows with privacy-first proof of real person presence.

Identity-backed actions

Confirm the right person is behind an account, request, or business action.

In-person QR checks

Use QR-based verification at venues, events, counters, receptions, and doors.

How it works

A simple model for privacy-first, consent-based verification.

1

Verify once

Users verify on their own device using biometrics, liveness checks, and optional government ID verification.

2

Turn verification into proof

Checkify turns completed verification into signed, time-limited proofs instead of sharing raw personal data by default.

3

Approve and share

Businesses request the proof they need by API or QR, and users approve exactly what is shared before anything leaves the device.

Choose your path

Whether you want privacy-first verification for yourself or your business, Checkify gives you a clear way to get started.

For users

Set up your Checkify identity once, keep your data on your device, and approve requests only when you want to share.

• Device-bound identity
• Consent on every request
• Reusable proofs
See user setup

For businesses

Request the proof you need, reduce data liability, and get an audit-ready record of verification events.

• QR and API-based requests
• Selective disclosure
• Audit-ready logs
See business setup

Security by design

Checkify is built so users stay in control and businesses can verify trust signals without becoming a data vault.

Device-first storage

Personal data is stored on the user’s device and protected by OS-level secure storage and biometrics. Sharing is explicit and consent-based.

Signed, time-limited requests

QR and API requests are cryptographically signed and expire automatically, reducing replay risk and making responses tamper-evident.

JWT + encryption in transit

Sessions and API calls use JWT-based authentication and are encrypted in transit with TLS. Tokens are scoped and time-limited to reduce exposure.

Selective disclosure

Businesses can request specific proofs or data points, but users review every request and must consent before anything is shared.

Audit-ready logs

Verification events include timestamps, decision outcomes, and reference IDs for traceability, without requiring businesses to store unnecessary personal data.

Privacy-first defaults

By default, Checkify shares proofs such as “Over 18” rather than raw personal data. Data requests can be restricted to only what’s needed.

Note: Exact security controls vary by deployment and integration requirements. We can provide a detailed security overview for partners, enterprise customers, and regulated environments.

Assurance levels

A flexible assurance model that lets businesses request the level of confidence they actually need.

Level 1

Basic

Device-bound presence and continuity signals for lightweight verification decisions.

Level 2

Verified

Liveness and biometric confirmation to strengthen proof of real-user presence.

Level 3

Verified +

Government ID checked on-device to provide stronger identity-backed assurance.

Level 4

High Assurance

Government ID verified on-device with stronger multi-signal assurance.

Verifiy & compliance roadmap

Security posture today, certification pathway tomorrow.

Investors, enterprise customers, and partners want evidence. This is how Checkify progressively strengthens privacy, security, governance, and assurance — from baseline controls to internationally recognised standards.

Step 1 Completed

ICO registration

Registered and accountable under UK data protection rules, with privacy-first governance in place.

Step 2 Next

Cyber Essentials

Baseline security controls across endpoints and cloud — access control, secure configuration, vulnerability management, patching, and malware protection.

Step 3 Planned

Cyber Essentials Plus

Independent technical verification that security controls work in practice, not just on paper.

Step 4 Planned

ISO 27001

A formal information security management system covering governance, risk management, policies, access controls, supplier oversight, and continuous improvement.

Step 5 Planned

SOC 2

Independent assurance for enterprise customers around security, availability, and operational controls across the platform.

Step 6 Target

DIATF-aligned certification

A target route toward government-aligned digital identity assurance for larger partners and regulated sectors.
