When you install Compass, we only analyze the conversations in your workspace's public channels. This allows us to create a graph which shows mentions between users, which partially represents your team's true conversational patterns.
The next step for teams who want access to richer data is to enable private message insights. After doing this, we will send each person in your team a notification, asking them whether they consent to having conversations in private channels and direct messages analyzed. We highly recommend that teams enable private message insights.
As a reminder, we don't store the contents of any messages we process (and this includes private messages).
After authorizing private messages, we will immediately analyze your private messages from the past quarter and from then on, we will analyze them in realtime as they are sent
