Favorites are not saved to Dictionary.com user accounts (the Favorites list is different than Word Lists.) Learn more about Favorites: How to Use, View, or Edit my 'Favorites' List?
iPhone apps:
If you subscribe to Apple's cloud services, iCloud, the words you 'Favorite' can sync to your iCloud and will be saved there, even if you uninstall the app from your device or view the app on another iPhone. If you are trying to view your 'Favorites' on another iPhone please make sure you are signed in to the same App Store account.
Our Free and Pro apps are separate apps, so, unfortunately, your 'Favorite' words cannot be transferred between the two apps. Outside of the iCloud solution we noted above, unfortunately your 'Favorite' words can't be transferred or moved to another device, or restored if lost when you delete the app.
Android apps:
There is not a current path by which one can move favorites between apps or devices.
Note: Our app itself does not currently support transferring or exporting your 'Favorites' lists.
Separately from Favorites, Word Lists can be accessed across apps and our website. when logged into an account
