The Jupyter Notebooks, which provide the interactive coding examples that help you learn to program the quantum computer, do not store user data. This means that the code in the notebook cells reverts to its default state when you exit the notebook or leave your session idle for 30 minutes.
If you want to keep any code you have developed in a notebook cell, cut and paste it to a file that you can save locally.
