In the previous chapter, we implemented most of the logic of our application. However, every time the user closes the application, all their tasks disappear. This is because our application is not persisting data.

To make data persistent, we need in some way to store it. The first intuitive way is to store the data locally, which means saving to a file.

PlayerPrefs in Unity
