# Contacts

Contacts are the foundation of Ariel's communication system. They represent the people and organizations you interact with through Ariel.

## Overview

Contacts in Ariel help you:

* Organize your communications
* Track interaction history
* Manage relationships

## Trusted Contacts

When you intially import your contacts or a new person calls, they are not a trusted contact. You can go in and manually set what contacts are trusted. This gives them access to your [calendar](/concepts/calendars) availability. If you have added a contact to an event they also receive information connected to that calendar event.

## Contact Properties

Each contact in Ariel contains:

* Basic information (name, email, phone)
* Interaction history
* Notes and reflections
