The real solution is to never send that data at all. I don’t trust any company when they say they encrypt data, unless they have their approach reviewed by experts in the cryptographic field.

Is it encrypted at rest or only in transit? What’s the encryption and the method? Where is the data stored?

It’s like giving someone the keys to your house simply based on a promise they’ll never enter.

Microsoft recently debuted their Recall feature and it was immediately found to have a major flaw in the security of the storage method for the files. These companies have proven they’re careless at every turn.
