Within PlayerPlus, your TRACKTICS performance data is displayed in the "Tracking" section, free of charge.
To see your data in PlayerPlus no further subscription is necessary. You only need the TRACKTICS app to transfer the data from the tracker to the TRACKTICS system.
You can decide for yourself if you want to continue using the TRACKTICS app without a subscription, just to transfer the data from TRACKTICS to SpielerPlus. Of course, you can also subscribe to TRACKTICS and use the app in its entirety for a fee.
