Apple has never participated in the CES alias Consumer Electronics Show. The largest electronic product trade show in the world is a venue for various manufacturers to show off their newest products.
Apple itself is more often introducing new products at the Apple Event which was held alone, and WWDC to introduce its latest software and platform updates.
Although it never introduced its newest product at CES, but that does not mean Apple is really not present at CES. Yes, this time Apple was present at CES not to introduce the latest products, but to display advertisements at CES.
The advert that displays the phrase “What happens on your iPhone, stays on your iPhone” is actually a “play on” version of the jokes of gambling players in Las Vegas “What happens in Vegas stays in Vegas”.
The point is that Apple wants to explain that all data and information about user activity on the iPhone will remain on the iPhone and not be sent to Apple or third-party companies.
Unlike its competitors who sell user data to third parties, especially advertisers so advertisers can provide the best advertising preferences for users.
Apple is known to highly uphold data and user privacy issues because according to Apple privacy is a human right. Every information and activity will be encrypted and remain on the user’s iPhone.
You can see complete information about Apple’s privacy on the Apple Privacy page.
