Secure Instant Messaging

K4 is a secure messenger that allows you to message your personal contacts safely and efficiently.

Most existing messengers fail to protect your privacy, the security of your attachments, your identity, or all of the above. K4 protects all three. Ditch email clutter and enjoy clarity, encryption and security in your communication.

Message professional contacts from a train, share documents while on foot, chat from your home or office — K4 organizes all of your communications in one place, while protecting your sensitive information.

Key Features:

- Personal and Private Chat that is Secure and Confidential

- Sharing of Text Files

- Sharing of Pictures from gallery and captured through the device in real-time

- Sharing of Audio files and recorded Voice notes

- Sharing of Video files from gallery and real-time recorded

Here’s a more detailed description of our proprietary feature set:

- Scheduled Delivery: Schedule delivery of a message or attachment for later in the day, allowing you to have complete control over when your clients receive sensitive information.

- Secure Video Calls: Our video calls help you match a face with a name, and make client communications more organic. These take place within the app, and are protected by the same technology that protects the rest of our platform.

- Auto-Response: Set up customized, automated responses for when you’re busy or away from the office. Your clients will never feel like they can’t get in touch with you!

- Acknowledgement: Messages must be acknowledged before being opened, ensuring that the sender can confirm reception of sensitive materials

- Priority Indication: Messages can be sent with a defined priority flag, ensuring that important messages can be seen as such

- Auto-Expiration: Messages will expire after the receiver acknowledges reception and the time set by the sender has elapsed

- Restricted Messages: Messages can be restricted from being forwarded and copied, so that you know your private conversations stay private.
