With the introduction of iOS 10 Apple is also introducing iMessage apps (extensions) and sticker packs. This is a category in which there is going to be a lot of new developers/designers/illustrators, new to the Apple ecosystem at least.
One thing that might be surprising to these app owners (if that is you, then you), is that Apple has a field for privacy policy in the iTunes Connect page where you submit all of the app information.
The main reason for this are data protection rules around the globe and we’ve written extensively about additional reasons in our guide for iOS apps. As of a couple of days ago, Apple has also updated their App Store Review Guidelines to incorporate language for stickers and iMessage extensions.
In section 5.1, the privacy section, you’ll find:
“(i) Apps that collect user or usage data must have a privacy policy and secure user consent for the collection. This includes — but isn’t limited to — apps that implement HealthKit or other health/medical technologies, HomeKit, Keyboard extensions, Apple Pay, Stickers and iMessage extensions, include a login, or access user data from the device (e.g. location, contacts, calendar, etc.).“
That being said, most sticker packs will likely not need such a privacy policy since it is impossible for them to collect user data. However, the more you’re working with the imessage framework and extensions, the more likely you are going to be in the market for that privacy policy (requirement).
