Can companies use user data for App Store marketing screenshots?

Question

Apple's App Store lets you preview features of a published app via screenshots, images, and even videos.

In the case of a social media app, those functionalities can only be shown through including pictures, account names and some account data.

Is it legal to have in such media, faces and data of actual people subscribed to said social media? Or, should the company ask for permission to each of the accounts that would be shown?

UPDATE: The nature of the question is whether using this data, without asking, is legal or not. In the described scenario might not be possible to ask for permission to each user and the only alternative would be to use dummy data. Moreover it is important to note that screenshots are a way of describing what an app does, so the exposed data would not be in a text format like a website but rather in some kind of view only mode (pictures or video)

Answer 1

Depends on the terms and conditions of the social media platform.

In order to avoid public controversy, although some may legally have the right to use your content, in practice, most reputable companies would ask for permission first, or create dummy accounts to avoid any legal issues.

Facebook will ask for your permission first.
