Typically Cloud works to seamlessly sync your personal language model as well as all purchases / downloads from the SwiftKey Store. All you need to do is sign into Cloud using the same Google Account.
We highly recommend enabling SwiftKey Cloud for its multiple benefits: personalization, better predictions, SwiftKey Store access, backup and sync and more.
- If you signed into Cloud and had your language synced on your old device(s), you can sign back into Cloud on your new device with the same email address and all of your learned data will be synced to the new device. You can also choose to not sign into Cloud and in this case, there would be no impact.
- If on your old device(s) you did not sign into Cloud, then Cloud on your new device will have no impact as there would be nothing to sync.
