This crate provides both a library to interact with iMessage data as well as a binary that can perform some useful read-only operations using that data. The aim of this project is to provide the most comprehensive and accurate representation of iMessage data available.

This free and open-source software can:

• Save, export, backup, and archive iMessage data to open, portable formats
• Preserve multimedia content (images, videos, audio) from conversations
• Facilitate easy migration of message history between devices and platforms
• Run diagnostics on the iMessage database
• Give you full ownership and control over your communication history
• Support compliance with data retention policies or legal requirements
• Run on macOS, Linux, and Windows

The imessage-exporter binary exports iMessage data to txt or html formats. It can also run diagnostics to find problems with the iMessage database.

Installation instructions for the binary are located here.

The imessage_database library provides models that allow us to access iMessage information as native, cross-platform data structures.

Documentation for the library is located here.
