Accessing recorded data of Arduino Uno

I am using an Arduino Uno and PIR Motion Sensors, is it possible for me to access the recorded data of the sensors using an app? So I can keep track that my sensors are detecting something?

Where, how, are they recorded?

Oh sorry, I mean if I am going to use some bluetooth module and existing Arduino app, would it be possible to access the data recorded by the Arduino Uno?

Yes.
The Dumpfile example included in the SD library should be all you need. Probably the simplest way is to access the file over Bluetooth.
