Looking for a Safe, Super Open Source (and also cheap if not free) Journaling app. Any Recomendations?

Hey guys, i am planning to begin my Journaling journey starting today. Any recomendations? I have already tried DayOne and Journey Didn't like them Particularly. DayOne seems uncool and even though they claim, a little unsafe. Plus i once before lost all my journal entries in DayOne bcoz i didn't save the encryption keys in my GoogleDrive. Journey is Worse (my opinion). They keep on pushing me to buy their paid option which costs 4$ per month. Like WTF. Its just a Journaling app. I am not going to try Penzu because i have heard a lot of bad reviews on how they cheat people and stuff. Finally i landed on DD-DigitalDiary which isn't open source. Which Sucks. But at least isn't costing me like 50$ a month or anything. Its mostly free. But i am looking or something better. More specifically OpenSource, Free (or almost free) and idk, modern & sxy Like when will these huge companies understand. Not everything needs to be VC funded. Next i am launching my VC funded Venture backed Fried Eggs company
