iCloud storage upgrade
What if I forgot/ stopped paying the plan. Will my uploaded documents be deleted?
Yes.
What happens when you decrease your storage plan
When you downgrade your iCloud storage plan, the storage decrease takes effect after your current monthly or annual subscription ends.*
If you downgrade or cancel your plan and your stored iCloud content exceeds your available storage, some of your data will not be uploaded into iCloud. Learn how to manage your storage by deleting information that you don't need anymore.
If you downgrade to the free iCloud Storage plan, you'll have 5GB of storage.
