iOS 15 and iPadOS 15 features an improved Intelligent tracking prevention that stops websites and trackers from knowing your real IP address. The Operating system keeps your IP address and email actions private from senders who insert tracking pixels into their messages. Mail privacy protection blocks tracking pixels by automatically downloading all remote images the second you receive an email and blocks your real IP and location from being known. This effectively makes tracking pixels useless, protecting your privacy. Does Apple OS assure of your privacy ?
