How Can I cancel Premium Subscription applied through Website Please?

I’m an Iphone User, So i applied through website for premium subscription, i know it’s 7 days trail, how can i cancel my subscription?

On your web browser, go to www.facer.io.
Login to your Facer account (the same one used to purchase Facer Premium).
Navigate to your profile and click the ‘pencil’ icon to edit your profile.
On the edit profile page, click the ‘pencil’ icon next to where it says ‘Subscribed’ in the Facer Premium section at the top.
Tap Cancel.
After successful cancelation, your subscription will lapse at the end of the current period and will not be renewed.

Many Thanks

Your welcome
