How do I prevent location-based applications from sharing my location

Hello people! Recently I’ve read an article about location based apps like Girls Around Me which can share my location without even notifying me. How can I prevent that from happening?

“A GPS satellite does not emit more power than a car headlight, and with that it has to illuminate half the surface of the Earth,” Professor David Last, former president of the Institute, told the BBC Royal Navigation. “A jammer of very, very low power that broadcast on the same radio frequency that the GPS will suffocate.

They are also used so that vehicles carrying valuable loads can be tracked. Researchers believe that most GPS jammers are used to prevent these devices from working. It was reported last week that a visitor was arrested after being caught sneaking into two cell phones inside the prison.

In fact, Girls Around Me app used Foursquare check-ins along with Facebook data for boys to be able to effortlessly track girls around them, but the purpose of that tracking was unclear. The website of that app had a slogan that hints on the usage of Girls Around Me app with the goal of either find your love or one night stand.

Although Foursquare pulled its API access and Girls Around Me app has ended its existence, there are many other apps which may become creepy. The app called Color can expose your photos from social media into the hands of any stranger, even those you don’t want to be shared. Another app, Find My Phone, may be used by any of your ex-partner in very abusive way
