Unfortunately we can't change or cancel your subscription for you. These are managed through Google Play and iTunes depending on which type of phone you have. Please see the appropriate section for canceling your subscription below:
If you are using Android, you can manage your subscriptions through the Google Play app. You should be able to open Google Play, go to My Apps, and then select Subscriptions. You should be able to select Pacifica Full Access and switch which subscription you're using, or cancel your subscription there.
If you are using iPhone/iPad, then open the Account Settings screen in the App Store app on your phone. In the App Store app, click the Featured icon and scroll down to where you see your iTunes ID. Click your iTunes ID and then click "View Apple ID". Then you can scroll down and tap Manage App Subscriptions. Tap the subscription you want to manage, then choose a subscription category. You can choose a different subscription period, or turn off Auto-Renewal.
Web via Recurly
If you subscribed via the web, your subscription is managed by the Recurly billing service. You should have received an email from Recurly confirming your subscription. This can be used to access your account and modify your subscription. You can also log into our web application at http://thinkpacifica.com/app, go to your account settings, and click on "Cancel Subscription" (this option is only available for web-based subscriptions).
