title: Is there a way to save data from users without registration in Flutter?
body: <p>I am currently building a Flutter app which lets users do personality tests, and until now I planned to do it without forcing users to register an account via Firebase (as this is annoying for many users).</p>
  <p>Problem I am facing now is that I need the results from the tests from the users, so that I can tell the users in the result section how these results are compared to the average of all people who have done the test.</p>
  <p>If a user would now register, the test results would be saved locally on the device. Will it then still be possible to save the test results in a online database?</p>
