We use Google Drive for most data storage on campus. You SHOULD have your Notability backing up to Drive automatically – if you aren’t or are not sure, CLICK HERE and make sure!
If you are in the middle school [in the 2022-2023 school year] then you are also using a Managed AppleID, which comes with 200 gigabytes of storage. The data and pictures that the 6th and 7th graders create on the Shared ipads automatically get backed up to their iCloud account – WHICH CAN ACCESSED USING ANY WEB BROWSER.
You 8th graders need to check some settings [See Settings –> Click on your name at the top left column -> iCloud -> Turn ON Photos, iCloud Backup]
To access your iCloud account, surf to iCloud.com
