LeetLink is a private peer-to-peer calling app for voice and video. Tap a contact, talk — that's it. WHY LEETLINK Direct connections — calls route peer-to-peer over WebRTC when possible, falling back to relays only when needed. No accounts to create — sign in with your phone number once, find friends by username. . Lock-screen calls — answer right from the lock screen with full CallKit integration. Calls behave like native iPhone calls. Background-ready — receive calls instantly even when the app is closed, thanks to VoIP push. Privacy by design — your contacts stay on your device. We only see hashed identifiers, never raw phone numbers. FEATURES Voice calls between LeetLink users Video calls with front and rear camera Lock-screen incoming call UI Contact sync (one-way, locally hashed) Push notifications for calls Encrypted signaling Works on Wi-Fi and cellular HOW IT WORKS Open LeetLink. Verify your phone number. The app finds which of your contacts also use LeetLink. Tap to call. The other side receives a native-style incoming call. Answer to start talking. There are no usernames, no friend requests, no group features. It's intentionally simple. PRIVACY LeetLink only stores the bare minimum needed to route calls: A hash of your phone number (not the number itself) Your push notification token Names you've assigned to contacts (stored locally, optional sync) We never sell, share, or analyze your data. Calls and media never touch our servers — they connect peer-to-peer through WebRTC.
