You can now request for your account to be put on Freeze plan at a minimal fee of $29 per month. Your content and web/native app will remain active, however, you would not have access to your PassionApps account and payouts while it's on the Freeze plan. You can reactivate at any time once you are ready to go back to building and monetizing your app.
To request the Freeze plan, simply fill out this form and choose "Freeze my plan for $29 a month" under the "What plan do you want now?" section.
