I want to delete my account or reset it in the app.

<NEXON Account>
If you're logged in with a NEXON account, you can delete your account through the app via [More > Account > Delete Account].

Please note that this action will remove your NEXON account from all services using that account, not just from the TFD Companion app. 

<External Account (Steam, PlayStation, Xbox)> 
If you're using an external account like Steam, PlayStation, or Xbox, you can reset your account via [More > Account > Reset Account] in the TFD Companion app.

Note that this will delete all TFD Companion app data. However, if you log back in within 15 days, the account can be restored.
