What is considered as a personal data that the cloud apps can store?

What is considered as a personal data that the cloud apps can store? Does the JWT token is considered as a personal data, or maybe just the accountId, email, username or something?
Thank you

Hi Ivana! AccountId is a personal-data-free replacement for the username. E-mail and username are also definitely personal data.

but the baseUrl, or JWT token are not?
