is this going to steal my personal information? i hear android apps do that because it's open.
There is no correlaiton between open-source and personal information theft.
Applications can access various bits of information about your device, such as IMEI number, read your contacts information, access SMS menu, send SMS, know about your location, etc. But each time you want to install a program the O.S. displays the list of the required permissions for the app to work.
So, if one day you install a "FLASHLIGHT LOL FUNNY" app that demands access to IMEI number, location, internet connection, etc, I hope you're smart enough to make the right choice.
(Well, you can also root your device to install a firewall, thus rejecting applications' demands to access various data).
