You can easily cancel any subscriptions through the app. Simply open Seven, and go to the 'Workout' tab, then tap > 'Settings' in the top right corner. In Settings, press > '7 Club' > 'Manage Subscription'. From here, you can cancel or adjust your subscription.
You can also start the Google Play Store app and find “Subscriptions” in side menu directly, find Seven there and click cancel from there.
Alternatively, you can visit https://play.google.com/store/account/subscriptions in your device browser and manage your subscription from there.
If this isn't working for you, please feel free to contact support and we'd be happy to help.
If you don't want to subscribe after the free trial, please remember to cancel at least 24 hours before it expires :)
