# What is TNG Identity doing with my data, and does it act as a data processor or controller?

TNG Identity operates as both a data processor and a data transmitter, providing secure handling and transmission of verifiable credentials.

### **TNG Identity Wallet**

The **TNG Identity Wallet** puts individuals in full control of their personal data. All data is stored in the device, encrypted and accessible using your biometrics. With the wallet, users can:

* **Securely hold and own their digital credentials**
* Easily **carry their credentials** within the app
* **Share information selectively**, only when necessary

This ensures true **data ownership** and **portability**, empowering users to decide **what** to share, **with whom**, and **when**—all while maintaining privacy.

### **TNG Identity Portals**

The **Identity Portals** enable organizations and individuals to **manage, monitor, and audit** verifiable credential operations through dedicated **Issuer** and **Verifier** portals. The portals store and encrypt all the information related to all credentials and provide comprehensive oversight of all credentials issued and verified, including:

* Credential issuance details (issuer, date, documents, credential data and status, etc.)
* Verification records (who verified, when, and the credential status at the time, etc.)
* Claiming activity (who claimed the credential and when, etc.)
* Full **auditability** of credential lifecycle events

This ensures transparency, compliance, and accountability across all credential interactions.

### Privacy by Design: Data On-Chain

At TNG, **privacy** is at the core of everything we do. No personal or sensitive information is ever stored on the blockchain. Instead, we only store on-chain:

* A **Decentralized Identifier (DID)** — a unique, anonymous identifier
* Your **cryptographic signature** 

This ensures that all users' data remains private and secure, while still benefiting from the trust and immutability of blockchain technology.
