A mobile phone application which helps jealous lovers keep tabs on their partners by secretly forwarding their texts has been removed from sale by Google after the company decided it violated its terms.

Once installed on the unwitting victim's phone, the Android phone app, called SMS Secret Replicator, automatically creates blind carbon copies of incoming text messages and forwards them to a selected number – prompting fears it could be used by partners and even work colleagues to snoop on private messages.

Jealous lovers are encouraged to secretly set up a password-protected app on their partners' phones and set it to forward text messages to their own. "The app is unique because there is no visible icon or shortcut to access it, so once it's installed, it will continue to monitor without revealing itself," said the developer, DLP Mobile. Its chief executive, Zak Tanjeloff, said the app was "certainly controversial but can be helpful to people in relationships where this type of monitoring can be useful".

The app's creators have given it the slogan "nothing is secret". Google confirmed it had suspended the app.
