The images below describe how the cross-device model works. The cross-device model is based on deterministic data like hashed email addresses and hashed phone numbers. All data of a user is linked to a Master ID which contains information about the user. The data is mainly collected through the on-site pixel. In order to collect data like hashed email addresses please enable the User Data modules in Data Collection (for more information see: On-Site Pixel Modules ).
