No. Netspark is installed once per device, not per user. 

On Windows PCs and macOS devices, the filter operates at the system level, meaning:

• All user accounts on the computer are protected

• Filtering applies equally to admin users and standard users

• There is no need to install Netspark separately for each user profile

Important

If Netspark is installed and active on the device, all users are filtered automatically, regardless of which account is currently in use.
