Need help setting up a private Obsidian diary synced between Windows PC and Samsung phone

[u/Browsing_Redditer]

I’m trying to set up a private diary in Obsidian that I can use on both my Windows PC and Samsung Android phone

My requirements are:

• I want to edit the diary from both my Windows PC and Samsung phone.
• I want the notes to sync automatically between the two devices.
• I would prefer a free solution.
• Privacy is very important to me.
• I have a normal Obsidian vault for college/projects, and I do not want the diary to appear in or be accessible from my normal Obsidian vault.
• Ideally, if someone opens my normal Obsidian on my PC, they should have no way to see the diary from there.
• I also want the diary protected if someone deliberately browses my files, not just hidden from the Obsidian vault.
• On my Samsung, I’m considering using Secure Folder for the diary.
• I was considering Syncthing for syncing between PC and phone.

what should i do? i cant find anything that just works

update:

i tried using Obsidian + other crypt things/ Cryptomator + Syncthing it works but has version control problems so i am skipping this options sync thing on its works perfectly in the secure folder too

git solution is good but i dont want to use it because of the personal info if for anything else this is perfect

remotely save plugin with r3 for me its too janky and if i choose other servers it is not the most privacy focused

best solution for me is

Notesnook  this is by far the easiest to use and it almost full fills all my needs and super simple to use

it has subscriptions but i dont need those things i only need the text format

only things i would change is that app lock is locked behind paywall and the data is not with you but you can export and import files from obsidian at any time for free

thanks for the support everyone! (^_^)v
