As a Family plan owner, you have the right to remove Family members from your Family plan. After you remove a Family member:

• they will still keep their pCloud account and the files inside. Learn more about what happens when your account runs out of storage
• their pCloud account will turn to Basic and they will lose access to all extra Premium pCloud benefits.
• they will receive an email notification, letting them know they've been removed
• they will not be able to access any services shared by your Family plan
