Friend Recommendations

ContactsManager SDK provides sophisticated recommendation algorithms that help users discover connections within your application while maintaining complete privacy of their contact data.

How It Works

The recommendation engine in ContactsManager uses a privacy-focused approach:

  1. Local Processing: Recommendations are generated on the device without sharing contact lists
  2. Privacy-Preserving Matching: Users are matched through secure cryptographic techniques
  3. Contextual Suggestions: Recommendations are based on multiple signals, not just contact presence
  4. User Control: Users always have the final say on which recommendations to act upon

Key Recommendation Features

  • People You May Know: Discover users within your application who might be real-world connections
  • Users of Your App: Identify which contacts are already using your application
  • Shared Connections: Find users who share mutual connections
  • Smart Prioritization: Recommendations are ranked based on relevance and interaction patterns

Privacy Protection

Friend recommendations in ContactsManager are fundamentally different from traditional social networks:

  • No contact data is uploaded or shared with your servers or ContactsManager’s servers
  • Cryptographically secure matching protects users’ privacy
  • All sensitive processing happens on the user’s device
  • Military-grade encryption secures any data used in the matching process
  • The user remains in full control of their data at all times

Applications

  • Frictionless onboarding with friend discovery
  • Building social graphs without requiring contact uploads
  • Increasing user engagement through meaningful connections
  • Growing your app’s network through trusted referrals
