Hi,

This is a slightly unusual question however, I need to better understand how Thunkable actually works as I am need to explain how Thunkable does some key function for a computer science project. My question is, how does Thunkable store permanent data to the user’s mobile device (i.e via stored variables) ? Is it stored as a cookie or maybe something else? If someone could explain this it would be much appreciated.

Thanks!

Jake.

`Stored variables` are stored in the `cache and app data` of the app itself.

You can easily verify it if you’re using an Android device. From the settings, go to your app and clear the `app cache and app data`.

Run the app and you should see that your `stored variables` have been set to **null** again.

For an iOS device, you have to uninstall and reinstall.
