Facebook-owned Instagram said that the new rules will not have any affect on the user's photos ownership or who can see them. However, they will help Instagram function more easily as part of Facebook by being able to share info between the two groups.
"This means we can do things like fight spam more effectively, detect system and reliability problems more quickly, and build better features for everyone by understanding how Instagram is used," Instagram wrote today on its blog.
In addition, Instagram may share User Content and information (including but not limited to, information from cookies, log files, device identifiers, location data, and usage data) with businesses "that are legally part of the same group of companies that Instagram is part of, or that become part of that group ("Affiliates")."
Instagram also added that the updated terms of service help protect users, and prevent spam and abuse.
