How a contact is shaped
A contact is a phone number plus the attributes you define, such ascity, email, lead_stage or budget. There are no built-in fields beyond the phone number and the channels the person has used (call, whatsapp), so the CRM holds exactly what your business tracks and nothing else.
Each stored value remembers where it came from:

Keeping contacts up to date
