Look at the former section "Proprietary Rights in Content on Instagram"
> Instagram does NOT claim ANY ownership rights in the text, files, images, photos, video, sounds, musical works, works of authorship, applications, or any other materials (collectively, "Content") that you post on or through the Instagram Services. By displaying or publishing ("posting") any Content on or through the Instagram Services, you hereby grant to Instagram a non-exclusive, fully paid and royalty-free, worldwide, limited license to use, modify, delete from, add to, publicly perform, publicly display, reproduce and translate such Content, including without limitation distributing part or all of the Site in any media formats through any media channels, except Content not shared publicly ("private") will not be distributed outside the Instagram Services.
This section about copyright has turned into something pretty much like Facebook's:
> Instagram does not claim ownership of any Content that you post on or through the Service. Instead, you hereby grant to Instagram a non-exclusive, fully paid and royalty-free, transferable, sub-licensable, worldwide license to use the Content that you post on or through the Service, except that you can control who can view certain of your Content and activities on the Service as described in the Service's Privacy Policy, available here:http://instagram.com/legal/privacy/.
