"We will never sell your data and will only use it to fulfill your completions or improve your results." Just to try and understand the nuance — "your results" is collective you here, right? As in, will things that Alice writes be used to make suggestions to Bob, or will they be ringfenced in an Alice-specific model? Are inputs being used to iteratively train models & then discarded or are they being held around in a corpus (presume the latter, since you mentioned encryption at rest)? How do you handle weeding out inadvertently storing/sharing sensitive info when training and suggesting? E.g. passport number, social security numbers, bank details etc.
