Apple has removed the Like Patrol app from its App Store, following Instagram's delivery of a cease-and-desist letter to the app's developers for violating its policies against data collection.

Like Patrol wanted to make spying on Instagram easier than ever, setting up a service that let paying subscribers get notifications anytime someone they followed commented on or liked a photo.

It targeted people in relationships, saying they could use the app to keep tabs on whoever their partners were communicating with on Instagram.

Instagram sent its cease-and-desist letter in late October.

On Saturday, Apple removed Like Patrol from the App Store and said the app violated its guidelines.

Like Patrol's founder, Sergio Luis Quintero, told CNET in an email that the company will fight to get back on the App Store.
