Private Messaging, Calling, and Meetings

Lochbox is designed to replace fragmented apps that compromise your security and your data. By combining high-definition voice and video with a “zero trust”, “privacy-first” architecture, it allows you to manage everything from critical conversations and team meetings to major life events, group scheduling, and daily check-ins within a single, secure ecosystem.

Unlike traditional messengers that broadcast your activity, Lochbox keeps you invisible. You control your presence through a closed-end, invite-only system, ensuring that your communications remain private and only visible to the people and projects you choose, completely free from outside interference.

Why Choose Lochbox

Lochbox goes beyond other privacy apps to ensure your data remains invisible to outsiders.

Invite-Only Connections

You are invisible to the public. No one can find your account or contact you unless you share your username, email, or phone number.

Spam & Scam Immunity

Because there is no public directory, uninvited parties and bots cannot send you messages or calls

Encryption Key Management

We use enterprise-level, end-to-end encryption. You have the option to hold your own decryption keys so that only you—not even Lochbox—can access your content

No Contact Broadcasting

We never notify anyone, including your phone contacts that you have joined the app, protecting your social graph

Stop being tracked. Create a Private Account

How to Organize Your Conversations

Lochbox keeps your different social and professional networks completely separate so that sensitive information never leaks between them. By using distinct network types, you can choose exactly how much visibility and control you want over your conversations. Explore the two ways you can organize your account below.

Personal Networks

The default setting for every user. It functions like a private phone line for your inner circle. Connections and chat history are hidden from everyone else.

Ideal for family, friends, and private 1:1 communication

Custom Networks

Custom private networks provide a designated space for conversations with groups of people that have a common interest like for business, teams, clubs, and family. Only members who are part of the network can see all members within the network in a secure closed-network environment and can speak freely. Each member of a network or group has to be invited to join in order to communicate freely. Within your network you can communicate and collaborate with others on an individual basis or by creating group conversations.

  • Admin: Full access to edit members and network settings.
  • Standard: Can communicate freely and invite new members.
  • Limited: Can communicate freely but cannot invite new members.
  • Restricted: Cannot see other members or start conversations; they can only respond to those who message them first.

Ideal for government, business, clubs, teams, or families.

Comparing Network Types
