4.4 Extensions

Overview

4.4 Extensions Apps hosting or containing extensions must comply with the App Extension Programming Guide, the Safari app extensions documentation, or the Safari web extensions documentation and should include some functionality, such as help screens and settings interfaces where possible. You should clearly and accurately disclose what extensions are made available in the app’s marketing text, and the extensions may not include marketing, advertising, or in-app purchases.

4.4.1 Keyboard extensions have some additional rules.

They must:

• Provide keyboard input functionality (e.g. typed characters);

• Follow Sticker guidelines if the keyboard includes images or emoji;

• Provide a method for progressing to the next keyboard;

• Remain functional without full network access and without requiring full access;

• Collect user activity only to enhance the functionality of the user’s keyboard extension on the iOS device.

They must not:

• Launch other apps besides Settings; or

• Repurpose keyboard buttons for other behaviors (e.g. holding down the “return” key to launch the camera).

4.4.2 Safari extensions must run on the current version of Safari on the relevant Apple operating system. They may not interfere with System or Safari UI elements and must never include malicious or misleading content or code. Violating this rule will lead to removal from the Apple Developer Program. Safari extensions should not claim access to more websites than strictly necessary to function.

4.4.3 Intentionally omitted.
