Sharepoint List Permissions NOT helping with GDPR compliance??

HI

Is there an ideas forum like in Flow and Powerapps!

Reading different blogs and posts its hard to believe that i can't set permissions for a user to add without view access! (unless im wrong and no we shouldn't have to use flow to plug  the gap!)

For my requirements i need:

Users submits data via powerapp to SharePoint list.

Flow sends copy of information to individual user so they have a copy.

Data in list is for analytics with Power BI and as contains all user info is restricted access but i cant restrict it..

Seems a major flaw to me and very frustrating!!!

Anyone have a solution?
