There is no real great privacy respecting note taking or journaling app out there that supports handwriting input using Apple Pencil or some other stylus. Most don’t support handwriting at all, including Proton Docs and Standard Notes, and the few that do aren’t great from a privacy standpoint. Most rely on Dropbox or iCloud.

Journaling or sketch writing is an inherently hand written process. Even jotting down notes in meetings.

It would be wonderful to see Proton adopt support for inputting handwritten test using an Apple Pencil/other stylus. This could be where Proton Docs/Notes acts as a blank canvas like Apple Notes or GoodNotes, or simply has a top-notch handwriting to typed text conversion process.
