SAN FRANCISCO  - Smartphone file-sharing apps Bump and Flock have announced that they will be discontinued at the end of January.

US Internet giant Google bought the Bump Technologies startup behind the apps in September for a deal reportedly worth between $30 million and $60 million. “We are now deeply focused on our new projects within Google, and we’ve decided to discontinue Bump and Flock,” Bump co-founder and chief executive David Lieb wrote in a blog post late Tuesday.

On January 31, Bump and Flock will be removed from both the App Store and Google Play, after which neither app will work and all user data will be deleted. Over the coming weeks, users can export their data by opening either app and following instructions.
