Yes. You can pause your subscription at any time directly from your Monthbook/Monthly Mini settings within the app. When you pause your subscription, it will appear as canceled in the app.
To pause your subscription, from the 3-bar menu on the left-hand side of the Chatbooks app, tap on "My Books."
From there, tap into the subscription you want to pause. Then, tap the Settings Wheel in the upper right-hand corner, and tap "Manage Subscription."
At the bottom of that page, you'll see "Cancel subscription." Tap there.
Then, select "I'm coming back."
Then, tap "Continue." From here, if you do select "Keep My Subscription," our Customer Support team will reach-out to you via email to help restart this subscription in 1 month or at a specified time that you choose.
