If you want to get an overview of your purchases made on findroommate and your membership status, you can go to 'My Premium' in settings.

Here you will find a list of all previous purchases (including date, price, terms and invoice)
Furthermore, you can see if your Premium is active or not. If active, you can see when it is set for renewal the next time. 

Finally, it is also here you unsubscribe your membership, when you no longer want to continue with it.
