I'm curious about how encryption works on iPads. I've heard that when you delete something, like a photo, the encryption keys get wiped out too. Can anyone break that down for me?
So, if I delete an image from my iPad and it's not backed up anywhere, once it's gone from the 'Recently Deleted' folder, is it really gone for good? And what about thumbnails—are they also erased, or do they stick around? Why do iPads handle deletion and encryption this way compared to other brands?

Apple has a lot of documentation on this if you want to read up:
* [Apple Platform Security](https://support.apple.com/guide/security/welcome/web)
* [Protecting Keys with Secure Enclave](https://developer.apple.com/documentation/security/protecting-keys-with-the-secure-enclave)
* [Apple Developer Security](https://developer.apple.com/security/)
To answer your question, yes, once an image is deleted from an iPad without backups, it is essentially gone for the user. You don't have direct access to the encryption keys, so data recovery isn't really an option. Although theoretically, an app could restore recently deleted files as long as that storage space hasn’t been overwritten, iOS limits apps' access to the system, making it really hard to recover files. That's why iPads prompt with those "Are you sure?" messages when you delete something.
The way encryption works can differ by app, so it depends a little on what you're using. Can you tell me more about your scenario?
It's pretty straightforward—images were deleted from 'Recently Deleted', no cloud sync or backups were made, and they're not stored in any app I have.
It's not that special; the iPad uses something called a secure enclave, which handles the encryption keys. If there are too many failed attempts to access it, the keys get wiped. Most devices nowadays have something similar for security, especially since Windows 11 requires a secure enclave as well.
So does that mean that once something is deleted, even thumbnails can't be recovered?
What about things like thumbnails though? Do those get wiped too?
