You can buy a subscription directly from the in-app store, from the “My Account” page. Whenever you tap a button leading to a paying feature (e.g. List of people who have Liked you), the app will also suggest you to buy a subscription.

You will then see a carousel in the top part of the screen which will list all the subscription advantages.

Different types of subscriptions are available, with various lengths. Purchases can be made via your iTunes or Google Play account. For this you will need your username and password.

If you get a multi-month subscription, the total amount corresponding to the entire subscription period will be charged all at once.

Moreover, please note that subscriptions are renewed at each period term unless you disable the automatic renewal on the App Store or Google Play Store.
