What happens with The files if I cancel The plan?

What happens when you decrease your storage plan

● If you downgrade or cancel your iCloud+ plan, the change takes effect after your current subscription billing period ends.

● If your iCloud storage exceeds your new storage plan capacity, iCloud won't sync or update your information. iCloud updates again when you increase your storage capacity or delete information to make more space.

● If you downgrade to the free iCloud plan, you will no longer have access to iCloud+ features like Hide My Email, Private Relay, and HomeKit Secure Video support.

● If you leave a family that shares an iCloud+ plan and you're using more than 5GB of storage, you can buy your own plan to continue using iCloud storage.

● If you choose not to buy your own plan and the content that you’re storing in iCloud exceeds your available storage, new photos and videos won’t upload to iCloud Photos, files will no longer upload in iCloud Drive, and your iOS and iPadOS devices will stop backing up.
