Question
What if the battery goes flat when I’m writing, will any data be lost?

Answer
You can still write and see the ink but the pen will not be able to record any more strokes. Should this happen, you will have to resort to retyping the information that has been missed.
All previous data is retained on the pen. The only way to wipe all data from the pen is through a factory reset or firmware upgrade.
