I'm using Evernote as personal knowledge base. You can structure your notes, add tags and use search.

This is a tall order, but I think Evernote comes closest. Can export in HTML, but not Markdown, unfortunately. The cross-platform-ness requirement is really going to limit you here.

The official app for Android & iOS. Meow.

This might be weird suggestion, but Reddit is an amazing personal knowledge base - that's how I use it! Create an account and make a private subreddit just for you. It's secure, it's got simple markdown and an API where you can fetch JSON, it has a search, tons of clients on all kinds of platforms, supports links, wikis, images, custom CSS, plugins... you can even use it as a file storage 👀

Works on Windows and Mac, Android and iPhone. No export to Markdown, unfortunately. But it is always free, as opposed to Evernote.

Todoist

The world's most powerful to-do list.

Primarily a todo app, but it does everything you are asking for. It's cross platform it's secure You can export your lists The search is amazing and instant You can create projects, categories, labels, and add new notes with a hashtag to these projects - and you can add files in comments to each "task", which you'd store as a title for your document It works offline - activates offline mode automatically as soon as an internet connection is no longer detected on any platform you are on such as iOS, Android or Web.

Just came across this today. Looks like it checks a lot of your boxes! It's cross-platform, open sources, plain text, exportable as text, end-to-end encryption, tagging. Been playing around with it for a little and it seems terrific. Definitely look into it.

I haven't tried this myself, but it looks like it hits a lot of the things you need.
