Hi Alba, welcome to JotterPad forum!
Transfer user data to new account
There is no way that we can transfer user data to your new account. However, setting up the same configuration is simple in JotterPad. For example, cloud services. You can connect the cloud services in your new account. The cloud services will be updated and shown in all devices connected to the same account.
Transfer of license to new account
You can simply login to the new email account on your iPad. Did you purchase a license on another account previously? If so, please send your account to email@example.com. We can transfer the license to the new account.
If you have any questions, please do not hesitate to get in touch with us!
