Lochbox: Communication Privacy 4+‎

Secure live chats, calls, and meetings in a private messenger that gives you exclusive control of your encryption. Like an adblock or antivirus for your conversations, Lochbox offers free voice and video calling, group messaging, and meetings that keeps trackers, hackers, and bad actors out. Protect your communications with friends and family, for your business or work and take comfort in knowing your personal, secret, and/or professional conversations can only be accessed by the intended parties.

User-controlled Encryption
Just because something is encrypted doesn’t mean it’s private or secure. If your service provider controls the encryption then they can access your content. When paired with our Key Manager app, Lochbox gives you exclusive custody of your encryption keys so only you can decide who has access. We couldn’t even view your content if we wanted to.

Connect Privately
Other messengers announce your registration to everyone in your contact list. We never share your account with anyone other than those you invite to connect. Lochbox even lets you keep your work and personal contacts and conversations separate so you can use the same device without exposing one to the other.

Free Chats, Calls, and Meetings
Send a message to one person or a thousand; talk using voice or video; meet or hangout with screen sharing on any supported device. Whether you don't like sharing your phone number or you don't have one we've got you covered.
