Smartphone photo sharing service Instagram on Monday refined its privacy policy to clear the way for sharing data with Facebook, which bought the company earlier this year.

“Nothing has changed about your photos’ ownership or who can see them,” Instagram said in a blog post.

“Our updated privacy policy helps Instagram function more easily as part of Facebook by being able to share info between the two groups.”

The changes were slated to take effect January 16.

Instagram maintained that the coming updates to its privacy policy and terms of service will help it improve the reliability of the service and fight spam.

Policy tweaks include allowing sharing of user information with “affiliates” in a move that could open the door to targeted advertising.

A social media feud between Twitter and Instagram escalated this month as the popular smartphone photo-sharing service made it impossible for Internet users to view its images in “tweeted” messages.

Instagram, which has some 100 million users, is seeking to route photo viewers to its own website, where it has the potential to make money from ads or other mechanisms, instead of letting Twitter get the benefits.

Previously, Instagram pictures shared in messages tweeted from smartphones could be viewed unaltered at Twitter.

Twitter responded by adding Instagram-style photo sharing features of its own.

Instagram rose to stardom with the help of Twitter, but has distanced itself from the messaging service since Facebook completed its acquisition of Instagram in September.

The original price was pegged at $1 billion but the final value was less because of a decline in the social network’s share price.

Instagram last month was given a Facebook spin with the roll-out of online profiles that let people showcase themselves and photos they have taken with the smartphone application.

People can share their profiles with whomever they wish, as well as “follow” other Instagram users, commenting on or expressing “likes” for pictures.
