Google is set to shut down its newly acquired file-sharing apps, Bump and Flock, by the end of the month.

Both the apps were developed by startup Bump Technologies, bought by the search engine giant last September in a deal reported to be worth up to $60m.

Bump co-founder and chief executive David Lieb said that the startup is now focused on its new projects within Google, and has decided to discontinue Bump and Flock.

"Bump and Flock will be removed from the App Store and Google Play [by January 31]," Lieb said.

"After this date, neither app will work, and all user data will be deleted."

Users are advised to export their data by launching either app and following instructions over the following weeks.

"At any point in the next 30 days, simply open either app and follow the instructions for exporting your data," Lieb added.

"You’ll then receive an email with a link containing all of your data (photos, videos, contacts, etc) from Bump or Flock."

The Bump app lets smartphone users share data by touching their phones together, while Flock provides a single repository for friends’ photos of an event taken on different phones.
