What do the STARS in the wallet mean?

If you tap on the star at the bottom of our app, you will be taken to the wallet area.
At the top you have two fields (Pockets):

1. Available
2. Pending

All stars that you have earned through activities in the current month are first collected in the "Pending" pocket.
In the night from the last day of the current month to the first day of the following month, we settle the Stars.
All stars are then transferred from the "Pending" pocket to the "Available" pocket.
All stars in the "Available" wallet can be exchanged for vouchers in our in-app store."
