This site is called Stripe Billing center (described in the next box ->)
It is firmly connected to preferences page in our app and you can easily go back from that site.
Stripe Billing Center is a service provided by Stripe (one of the world's most used payment gateway) for management subscriptions.
It would took us weeks of work to only implement our own mechanism to control subscriptions, so we decided to use Billing Center. This allow us to spent more time improving our app.
