Selfhostable notes app that encrypts the files on Disk?

Hey everyone! :)

I am currently looking to replace Obsidian with a self-hostable alternative (that preferably also uses Markdown - but it's not a must) but instead of storing the files directly on disk has a way to have all the files within in an encrypted vault / binary format.

Reason being I have very very sensitive data that needs to be stored (employee & medically related).

I read that Logseq used to support this feature but it has since been deprecated, some light googling didn't surface any results other than that so I would be delighted if anyone had any suggestions!

Thanks so much in advance for any and all help! :)

edit: Forgot to mention that it needs to support Linux as well as Android

  • if you're encrypting at rest you also have to consider where there encryption key is being stored.

    if you're storing the encryption key plaintext on the same drive as the data, there's not much of a point in encrypting.

    a TPM/HSM could solve the issue, depending on how far down the rabbit hole you need to go.

    EDIT: You could also encrypt the disk of the VM/Server hosting the app. similar situation.
