Location settingsPay attention to location settings when you use social media sites and apps. Some might be tracking your whereabouts even when you told them not to like Google was caught doing last year. Your location might not seem like a very valuable piece of data. However, when paired with your other personal information, it could help to create an even more accurate user profile.Real-life thieves and stalkers could also use location data. Imagine if a criminal knew where you are at all times. They could easily break into your house when you weren’t there or follow you home.
