Instagram reverted the advertising section of its new policy to its original version after facing criticism.

Instagram on Thursday siad it has reverted the advertising section of its new privacy policy and terms of service to the original version in effect since the company launched its service.

Instagram is "going to take the time to complete our plans, and then come back to our users and explain how we would like for our advertising business to work," the company's co-founder Kevin Systrom said in a blog post late Thursday.

The photo-sharing service on Monday announced a new privacy policy and terms of service which would come into effect in January. But it faced a backlash from users who were worried that Instagram would use their photos and other information in advertisements without their permission.

Systrom wrote in a blog post on Tuesday that Instagram has no intention of using photos within advertisements. "We do not have plans for anything like this, and because of that, we're going to remove the language that raised the question."

Systrom reiterated in a blog post that the company had no plans to sell user content. "I want to be really clear: Instagram has no intention of selling your photos, and we never did. We don't own your photos -- you do," Systrom wrote in a blog post.
