> Bringing data ownership back to you

Calimero Network enables building self-sovereign applications with data ownership and verified computing capabilities.

Calimero Network helps developers build peer-to-peer applications focused on data ownership. It includes verification systems to check the authenticity of actions, encryption for messages between users, and local storage options. Applications built with Calimero store data on user devices, verify actions with digital signatures and maintain private communications between peers.

## Products

- [Calimero Network](https://thegrid.id/profiles/calimero): Calimero Network provides tools for building self-sovereign applications that store data locally on user devices. These applications use client-side validation to verify actions, secure encryption for protecting communications, and local data vaults to maintain user control. Developers can create applications using standard programming languages without specialized cryptography knowledge.  (Developer Tooling, Live, Main Product)
