Apps that stream, display, or bundle third-party copyrighted content need documented rights or a license — Apple will ask for proof of rights if content ownership looks unclear.
Common in media/streaming apps built quickly with placeholder or scraped content that was never actually licensed for redistribution.
"Your app contains content that you do not have sufficient rights to use, or that infringes upon the rights of a third party, per guideline 5.2.1."
Guideline 5.2.1 requires apps that stream, show or bundle third-party copyrighted content to have documented rights to do so. If ownership looks unclear, Apple may ask for proof such as a licence. Media and streaming apps built quickly with placeholder or scraped content are the most common cases, because the content may never have been licensed for redistribution.
Apple does not want the Store to become a route for copyright infringement, and it receives legal complaints from rights holders. Asking for proof of rights puts responsibility on the developer to show that the content is theirs to use. The guideline protects creators and also protects Apple and users from takedowns that leave an app unusable after people have invested in it.
Licences, agreements or other documents showing the developer can use the content.
It overlaps with user-generated content rules and the developer's takedown process.
Licensed stock is fine within its terms.
