Apple (AAPL), on Monday, announced a slew of major privacy improvements across its product lines during its Worldwide Developers Conference (WWDC) 2021. The changes include the ability to prevent third-parties from tracking your online activity, a new App Privacy Report, and enhanced privacy when browsing the web as part of the company's new iCloud+.

The changes follow Apple's release of its App Tracking Transparency feature, which allows users to choose whether the apps they use can track their activity across apps and the web. The company's new anti-tracking capabilities include the ability to prevent email senders from knowing if you open their messages in the Mail app. You'll also be able to prevent senders from tracking your IP address, so they can't track you as you navigate the web.

That could prove troublesome for online marketers, and the burgeoning newsletter business, which rely on information about whether readers open emails or not. In Safari, Apple is adding the ability to hide your IP addresses from third-party trackers, which prevents them from being able to create advertising profiles on you based on your activity online.

More interesting is the new App Privacy Report feature. This will allow users to see how often apps are accessing the data and sensors they've previously given them permission to use. For instance, if you've given an app the ability to track your location, you'll be able to see how often the app is checking in on you. Think the app knows a little bit too much about where you are? You can turn location tracking off.

What's more, the report will provide you with a list of the various third-party domains your apps are sharing your information with. That's sure to rankle the feathers of developers who rely on the ability to share user information to generate revenue.

iCloud+ let's you browse with less tracking

Then there's Apple's new iCloud+. The service, which is the same price as current paid iCloud subscriptions, includes three new features that help improve your privacy online. First is Apple's new Private Relay, a virtual private network, that routes your web traffic through two, well, relays, that ensure your exact location is hidden from trackers and prevents trackers from knowing what websites you visit.

The second iCloud+ feature includes the ability to use burner email addresses when signing into or signing up for sites that you don't necessarily trust not to spam your inbox. When you sign up for a site using a burner address, emails sent to the fake address will be forwarded to your actual address. Get tired of receiving emails from a site? Simply delete the burner email and you're off their grid. Apple offers a similar feature as part of its Sign in with Apple.
