Oh, markup?
Prob theres no e2ee application with that feature.
I think Evernote, Onenote, GoodNotes can do drawing.
Not sure if Joplin does that. Maybe obsidian got a plugin that can add drawing.
If you are solely looking for only handwriting/brainstorming similar to FreeForm I guess you can use something like Excalidraw.
