If you're moving to a new phone, you may be able to back up all or some of the app's data—depending on your device's maker. If you're moving from one Samsung phone to another, Smart Switch can accommodate you. If you move from one Motorola device to another, they have a migration tool, as well.
Without a Pro subscription, you can back up the last year of one of your Journal projects for free. If you want to back up more than a year, start your free 7-day trial of Pro today!
