No? It’s literally not a thing on any android. I just pretty extensively looked for any evidence of this online and I can only see people misunderstanding the feature of removing permissions for unused apps. One of the permissions apps are granted is storage, and that permission can get revoked if that feature is turned on. This does not delete stored data (it does not remove data the app has already written) but removes the apps ability to read or write to storage further, and can cause any temporary storage like cache to get erased. This will cause your accounts to get signed out and could potentially lead to data loss, but not because the operating system is actively and purposefully erasing data.
Whenever I see a checkbox or something that just says “Check here to confirm you accept our privacy policy” I think it’s funny because all I am legally agreeing to are the words actually in front of me. Sure, I agree with the standalone words “our privacy policy”. I’m not sure what that does for you, but i guess “our privacy policy” is an acceptable string of words.
