NOTE: These security measures only apply when your friend also uses ChatSecure, or uses a compatible OTR client like Xabber, Jitsi, Adium or Pidgin.
★ NO SNOOPING: Your connection is encrypted so nobody can spy on your conversation. And the messages aren't even kept in system memory for any prying apps to find.
★ FULL LOCAL ENCRYPTION: All contacts, messages and account data are fully encrypted on your device, and protected by an optional password.
★ COMPLETELY FREE, UNLIMITED MESSAGING: No charges, ever. Chat all day with your friends across the street or across the ocean.
