Facebook Login + PlayFab

Hi!

I have a game where I do use Unity Ads, Facebook Login, and PlayFab for saving the data online.

I received an e-mail from Facebook :

"Platform Terms 4.b: Your privacy policy must comply with applicable law and regulations and must accurately and clearly explain what data you are Processing, how you are Processing it, the purposes for which you are Processing it, and how Users may request deletion of that data.

During testing, we found that your privacy policy doesn’t explain how users can request data deletion. Update your privacy policy to include this information before you submit an appeal."


Has anyone received this email from facebook and how did they solve it?
I don't even know what data they want me to give Delete option, whether from Unity Ads, Unity Analytics or cloud game saves

Has anyone gone through this and solved it?.
