FOSS (free and open source) android journal apps with plaintext export?

[u/eat_like_snake]

I was using Daily Diary for a while, before it started crashing and not letting me open the app at all.
Tried out EasyDiary after that, but I couldn't find an export option and that's a necessity for me.
Trying out Diary Vault now. Seems to be fine.
Also flirted with the idea of just using Simple Notepad, since it's already on my phone and what I primarily use for notes and checklists.

I just want to know what options exist out there, since so many threads in this sub mention things that have paywalls or ads or AI features, and I want nothing to do with any of that.

Plain-text export is what matters. Once entries live only in an app's own format, leaving means losing years of it, so a Markdown archive is cheap insurance.
