Instagram lost almost a quarter of its daily users a week after it rolled out and then withdrew policy changes that incensed users who feared the photo-sharing service would use their pictures without compensation.

Instagram, which Facebook bought for $715 million this year, saw the number of daily active users who accessed the service via Facebook bottom out at 12.4 million as of Friday, versus a peak of 16.4 million last week, according to data compiled by online tracker AppData.

The popular app, which allows people to add filters and effects to photos and share them over the Internet or smartphones, experienced the drop over the brief, often-volatile holiday period.
