What Safe Whisper gives you: • Ephemeral encrypted conversations • End-to-end encryption for messages and files • In-person QR code key exchange • Private keys stay on your devices • No contacts access • No personal data stored • Expiring conversations • Secure file sharing • Read receipt control • Simple invite links and QR codes • One month free with an eligible subscription Safe Whisper is for people who need a focused, private space for sensitive communication without giving up their address book, identity, or long-term message history. Use it for confidential chats, temporary project discussions, sensitive file exchange, private coordination, or any conversation that should stay between the people involved and disappear when it is no longer needed. Subscriptions renew automatically after the free trial unless cancelled. You can manage or cancel your subscription anytime in your App Store account settings.
