I want to store detailed user information that can be updated only by paid members in the database

I would like to create a site that provides monthly web service and store user settings for each member in the database.
Current situation / problem
I created an application form input form using wix code, but there are some problems with this method.

  1. From the wix code database, we can not judge which members have registered data and which fee plan they subscribe to.
    (It can be determined by having a login email address registered, but it can be exploited by using other people 's email address and there is a security problem.)

  2. In the input form, data on the input form disappears at the time of transmission, and the user needs to fill in all the information every time.

I would appreciate it if you could tell me if there is a solution. Thank you.
