Blockchain and Transparency

​
Public Blockchain Records

​
Data Storage and Security

​
Decentralized Storage

  • Blockchain: Verification records are stored on the Base network
  • Application Data: Minimal application data is stored on secure servers

​
Security Measures

We implement industry-standard security measures including:
  • Encryption of data in transit using HTTPS/TLS
  • Secure smart contract development practices
  • Regular security audits and updates

​
Compliance

Shield strives to comply with applicable privacy laws and regulations. However, users should be aware that blockchain technology operates differently from traditional databases and some privacy rights (such as the right to deletion) cannot be fully implemented due to the immutable nature of blockchain records.
By using Shield, you acknowledge that you have read and understood this Privacy Policy and agree to the collection, use, and disclosure of your information as described herein.
