PostHog tracks user behaviour, whether or not the User is logged in and identifiable.
A short video on Users can be found here: https://youtu.be/8_SsZW1v56Q
Go to the ‘Users’ list in the left hand navigation:
You will see a list of users, something like this:
The first user has had no identifying information pushed to their profile in PostHog. That is why a string appears.
The second user has had their email address passed to PostHog.
Clicking on an individual user brings up their entire event history:
You can go even deeper by inspecting each event individually. Click on the event to bring up the event properties. This shows you the following information:
You can also delete data on a user, this can be done if you have created data by yourself by testing or if a user asks you to do so.
When in the user history you can select 'Delete all data on this person' this will delete all information on that user permanently.
