Stealth Technology

Stealth is the only instant messaging app with Encryption³; Encrypted messages in transit, encrypted data on disk and encrypted display.

  1. Encrypted display:

    Messages are displayed encrypted on your device's screen until you unlock it. Someone looking over your shoulder or picking up your phone can’t view your message history, or even who you have been talking to.

  2. Encrypted in transit:

    We use Peer to Peer encryption technology, to encrypt your messages and files before sending. This means only you and the receiver can read them. Each message is encrypted with its own key and in the extreme event of your private key being discovered no message you ever sent can be decrypted! The messages are then further protected by being sent over an SSL secured data channel.

  3. Encrypted on disk:

    Your received and sent message history is stored securely on disk using best practice including AES/EAX encryption using a PBKDF derived password. If that isn't enough you can set a burn time for your messages after which they are deleted from your and the receivers history.
