Does this mean they are training a model on their users' notes? Or does it all come from a separate model e.g. GPT3?
Notion may, however, use your Content or Customer Data to improve and train Notion’s own models.

> Marvin from Product Operations here and happy to clarify. The answer you're looking for is: no we are not using your data to train our models.
"We do not and will not use your Content or Customer Data to improve or train our models unless you give us express permission to do so."
Maybe they changed this in the past 7 hours?
In transit means https (like your comment getting sent to this page).
At rest means the underlying store uses a key, like S3, or even HDD encryption. It's encrypted on write to the disk, and decrypted on read. This may be fantastic for when nation state black ops sneak into the data center and remove the server's drives for forensic analysis, useless for anything else. (To be fair, it's useful on a laptop. Not so useful in a data center.)
Neither of these means it's encrypted between reading disk and sending over HTTPS.
Neither one means employees, servers, or clients, can't see your data.
I really liked notion as a product. This is kind of a wakeup call for me that using the cloud pretty much means giving up control - and not just theoretically.
