# Frequently Asked Questions
Is the TS3 Manager free?
Do I need to host the TS3 Manager by myself to use it with my Teamspeak3 server?
No. You could just use the demo version and log in to your server and start administering it.
Where are the login credentials stored?
The login credentials for the serveradmin are only stored locally and encrypted in your browser session. No passwords are stored on the server side.
Do I have to whitelist the TS3 Manager?
No not necessary. Unlike other web based solutions for TeamSpeak, the connection between the TS3 Manager and the ServerQuery is kept open until you logout, close your browser tab or refresh the page. Because of that the anti-flood detection by the ServerQuery will not be activated.
Is there a mobile app?
The TS3 Manager is a Progressive Web App. If you open the TS3 Manager with the chrome browser on your android device it will show up a notification where you can add the application to your homescreen. On iOS there is no notification. You have to add the webpage manually to your homescreen with the safari browser. See also /guide/MobileApp.html
