Pinterest announced its support for Do Not Track, a mechanism that allowed users to opt-out of having websites and third parties collect their personal data and activity. Through the introduction of "Edit Your Home Feed", Pinterest addressed public concern over online tracking.

"Edit Your Home Feed" offered a more personalized experience for Pinterest users. The feature will track a user's activity and suggest boards based on their interest. However, it was also easy to opt out of this feature.

This Do Not Track feature was not the first in social media sites though. Twitter already announced a similar mechanism last year.

"Consensus around the technical specs for Do Not Track remain elusive. However, we believe people are making a choice when they turn on Do Not Track. Today, we're committing to respecting that choice," said Pinterest in a statement.

Pinterest is a photo-sharing website that allowed users to create and manage image collections pinboard style. The company was privately held and do not disclose financial details to the public. However, according to Ben Silverman, its executive and co-founder, the company was valued at US$2.5 billion during its latest investment round.
