Self-hosted diary

Looking for a self hosted diary type of service. Where I can login and write small topics, ideas, tag them and date them. No need for public access.

Any recommendations?

Edit: anybody using monicahq or has experience with it?

Clarification: indeed I could use a general note taking app for this task. I already host and use silverbullet for general notes and such. I am looking at something more focused on daily events and connections. Like noting people met, sport activities and feedbacks, names, places... So tagging and date would be central, but as well as connections to calendar and contacts, and who knows what else... So I want to explore existing more advanced, more specialized apps.

Edit2: I ended up with BookStack. MonicaHQ seems very nice but proved unable to install using containers. It would not obey APP_URL properly and would mess up constantly HTTP / HTTPS redirection. Community was unrepsonsive and apparently github issues are ignore lately. So i ditched MonicaHQ and switched to BookStack: installed in a breeze (again container) and a very simple NGINX setup just worked. I will be testing it out now.
