About this app

myAge is a privacy-focused age authentication tool designed to help users
generate and verify age-related claims without sharing personal information.

The app allows users to create a secure key pair, sign messages, and generate QR codes containing signed data. These QR codes can be used to quickly verify age-related information in a simple and efficient way.

All signed data is stored locally on the device. The app does not collect, track,
or transmit personal information. There is no requirement for email, name, date of birth, or any identifiable data, giving users full control over their digital
credentials.

Key features:
• Generate a cryptographic key pair on-device
• Sign data securely for verification purposes
• Create QR codes containing signed information
• Store signed data locally on the device
• No tracking, no data collection, no external transmission

The purpose of the app is to provide a lightweight and privacy-first approach to age verification workflows. It enables users to demonstrate age-related claims without exposing sensitive personal details.

This approach supports user-controlled digital identity and promotes greater
privacy and data minimisation in everyday interactions.

The app includes NFC functionality, and it is the user’s choice whether to use it or not. The app can operate without using this functionality or an NFC tag.

If you choose to use an NFC tag (xStringTech terms: Lockcard / Lockfob), you may obtain a tested and compatibility-verified tag from us. Each tag includes a verified 12-digit setup code for use with the app.
