Here are the terms that Apple must adhere to:

1. Imposing any commission or any fee on purchases that consumers make outside an app, and as a consequence thereof, no reason exists to audit, monitor, track or require developers to report purchases or any other activity that consumers make outside an app;

2. Restricting or conditioning developers' style, language, formatting, quantity, flow or placement of links for purchases outside an app;

3. Prohibiting or limiting the use of buttons or other calls to action, or otherwise conditioning the content, style, language, formatting, flow or placement of these devices for purchases outside an app;

4. Excluding certain categories of apps and developers from obtaining link access;

5. Interfering with consumers' choice to proceed in or out of an app by using anything other than a neutral message apprising users that they are going to a third-party site;

6. Restricting a developer's use of dynamic links that bring consumers to a specific product page in a logged-in state rather than to a statically defined page, including restricting apps from passing on product details, user details or other information that refers to the user intending to make a purchase;
