Yes, It simply means that your app is collecting data from users [without user permissions you can not collect data without their permissions.
Solution:
Remove the Cookies from your app [which is collecting user data] [actually it simply means that you might sell this data to any advertisers]
Go to App Privacy and set your data types[ if you are collecting then follow the apple app store data types privacy policy]
if you are not collecting data [then simply check to "NO"
I hope it will help you
