# UserPoint

A UserPoint is **a 360° vision of a unique user on the platform**.

![](/files/-MUE3pwGGsiykvbo7sio)

It is composed of different sets of data to cover all the user aspects providing a 360° view (online and offline): 

* [UserActivity](/user-points/user-activities.md) represent an interaction with the user
* [UserProfile](/user-points/user-profiles.md) represent a summary of timeless information about the user, like first name, last name, birth date...
* [UserSegment](/user-points/segments.md) are here to capture that the user belongs to a particular group of users
* [UserChoice](/advanced-usages/data-privacy-compliance/user-choices.md) capture that the user has given his consent for a specific type of data processing
* UserTrait represent a calculated attribute used to describe the user. 

## UserPoint merges

Imagine you are going to a site with firefox, and you go back to that site later on safari. At the moment, there is no way for the platform to know that all those actions are from the same user. You'll have two UserPoints: one with the UserDeviceTechnicalId from firefox and the other with the UserDeviceTechnicalId from safari. \
\
If later you log into the site with your UserAccount on both navigators, the two UserPoint will be associated with a common UserAccount ID identifier. The platform will automatically merge the two UserPoint and their activities to represent the reality that we now know those two users were the same.

UserPoint merges can only be triggered by :

* [UserActivity](/user-points/user-activities.md) updates
* [User identifiers association declarations](/data-streams/data-ingestion/bulk-processing/user-identifiers-association.md)

The merge will result in a UserPoint survivor, to which we migrate all the data related to the previous two UserPoint.
