identifying the touch in ILI9341

Hi everyone,
I am using arduino uno board with ILI9341 touch screen LCD display. Now, my objective is to transfer whatever data we write/draw on touch screen should be transmitted. But the problem is how can I transfer the data written/drawn on touch screen through Arduino Uno. I seen every project articles but I am not getting any answers on how can I store the data which is written on touch screen.
Thank you in advance.
Here's the link from where I have bought the touch screen: ILI9341

I am not getting any answers on how can I store the data which is written on touch screen.

Where do you want to store it ? On the Arduino or the PC ?

You could collect the data, such as screen coordinates, using the Arduino and pass it to the PC using a Serial link for it to be stored on the PC but you will need an application running on the PC to receive and store it.
