Should Apps Be Allowed to Track Your Location

When I download an app, I feel that the policies should state whether they are using my personal information or not because I for one am a very private and cautious preson. The police should be allowed to use you GPS information so that they can protect you in something ever happens where you are in court and you need to know where you were at during a specific time and date. I presonally don't use apps that post my location because I don't want no one asking me questions like, where are you at, why are you there, etc... I feel like if you want to know where I am, that you will ask me.
