Online casinos offer you different responsible gambling settings. You can normally set deposit limit, loss limit, play-through limit and time limit. In some casinos you can set up all of them. In some casinos some of them. Some casinos don't offer you any responsible gambling settings. Whenever you have the option, be sure to use the responsible gambling options! And set yourself limits in EACH and EVERY casino you open an account in.
Winnings Tracker can not and does not replace the settings in casinos.
