What happens after app uninstall
There's no need to uninstall the app if you temporarily stopped using it. You can switch to Free plan and keep the app until you need to change prices next time.

When you uninstall the app all price changes that you've made will stay. All your tasks and sales will be saved in app for 90 days after uninstall. During that time you'll be able to reinstall the app and rollback any task or disable sale. After 90 days after uninstall all tasks and sales data will be permanently deleted and you won't be able to rollback any price changes. If you want to keep old tasks and sales we recommend keeping the app installed and switching to Free plan instead.
