The terms used in this Privacy Policy have the same meanings as in our Terms and Conditions unless otherwise defined in this Privacy Policy.

Important: Your device contacts are encrypted on your device before being synced to our servers.

The encrypted contact data enables cross-device sync while keeping your contacts private and secure.

Profile Sharing

When you choose to share your Linkt profile link with someone, they will be able to see your:

  • Full name
  • Username
  • Profile photo (if you've added one)
  • Bio and any other information you've chosen to make public

You have full control over what information appears on your public profile. Your connection logs and private data remain encrypted and are never visible to others.

Data Encryption & Security

Your private data is protected with industry-leading encryption:

  • End-to-End Encryption: All private data (contacts, connection logs, interactions) is encrypted using AES-256-GCM encryption
  • Per-User Master Secret: Each user has a unique 32-byte master secret generated server-side, never exposed in plaintext
  • Device-Specific Wrapping: Your master secret is wrapped separately for each of your devices using ECIES-P256 encryption with Secure Enclave protection on iOS
  • Secure Key Derivation: Encryption keys are derived using PBKDF2-HMAC-SHA256 with 210,000 iterations, exceeding OWASP 2024 standards
  • Secret Manager Integration: Server-side encryption keys are stored in Google Cloud Secret Manager, never in application code
  • Transport Security: All data in transit is protected with HTTPS/TLS encryption

Your encrypted master secret is stored wrapped in Firestore under secure access controls. Only you can unwrap it using your device's private key, protected by iOS Keychain and Secure Enclave where available. This architecture ensures that even if a single device is compromised, your master secret can be rotated and re-wrapped for your other devices.

We use Google Cloud infrastructure which provides enterprise-grade security features including infrastructure-level encryption at rest, physical security at data centers, and regular security audits. Access to your data is strictly limited to authorized personnel only.

While we implement strong security measures, please note that no method of electronic storage is 100% secure.
