Data storage is crucial for applications that monitor the progress of users and allow login or perform any other crucial function. There are several ways to store user data but the most efficient solution is dependent on what sort of problems you’re trying to solve.

Local storage is ideal for storing small amounts of data that don’t require instant sync, like user registration or login information. However, it’s restricted by the size of the device’s hard drive and is only accessible via client-side code (and isn’t manipulated by server-side scripts). Local storage is also susceptible to lose data when an application is removed, or the device reset.

The database storage is perfect to store large amounts of data that will need to be edited. You can keep track of the information of your users by saving the unique identifier of each user and then refer to it whenever you access the database. This is more complex than other storage options for data however it is an ideal choice for large or enterprise apps that require storage of user data over multiple sessions.

WebView2 stores the data of your browser using UDFs. This includes http://www.virtuadata.net permissions, cookies and cached resources. This data expires based on the user’s Web & App Activity settings. It’s also possible to be cleared manually by the user using Actions on Google. You must select the UDF that has Write access to the WebView2 in order to save additional user data. See the WinUI 3.cs file in the WebView2Samples repo for an example of how to do this with ICoreWebView2Environment7.
