Selfhosted

Hello everyone, I'd like your recommendations for a note taking app that:

• Can be selfhosted
• Stores the notes as plain text or *.md files, not some SQL database.
• Can use Marddown format.
• Have an android client or at least a mobile optimized web-interface.
• Not a must but it would be nice to have a to-do list option.

I tried:

• Trilium: use an encrypted litesql to store the notes.
• Joplin: does not encrypt the notes, but store them in random named directories, making ot harder finding the notes.
• Logseq: No firefox support, I did not check how it stores itsdatabase.
• Standard note: Need subscriptions to selfhost or to use markdown format.
• Memos: does not store plain files, instead uses a (sqlite probably) database even when setting local filesystem as current object storage.
• CodiMD: use database to store its notes
• Hedgedoc: the same as above

The closest I found so far is Obsidian, which:

• Unfortunately, does not have any selfhosting option.
• Have a client app on every platform and store.
• Can use a custom directory to store it database as plain text files, whuch can be a network mounted directory (on my laptop/desktop) or a directory on my android phone that i will have to keep synchronized using a third party app.

Edit: March-2nd: added memos, codimd, hedgedoc
