Do I need to sign up for MediBang to purchase MediBang Premium?

[Purchasing on the website]

You will need to sign up for a MediBang Paint account.

[Purchasing on Apple Store or Google Play Store]

It is possible to purchase without creating a MediBang Paint account, but some features will not be available (including version control or cloud storage). It is recommended that you use the application after signing up for a MediBang account and logging in.
