Looking for a Privacy-Focused Simple & Minimalist Daily Activity Tracker

I’m looking for a way to track my daily activities for personal insights and self-awareness. I’m not interested in anything complex or with extensive social features – just a simple tool to log what I’m doing and when.

I’ve been considering manually logging things in a note-taking app, but I’m hoping there might be dedicated tools that offer a more streamlined experience.
Is there a privacy-focused daily activity trackers solution?

You could have a Bullet Journal or modified Bullet Journal going in any kind of note/text app.

Sounds like what I do - in Joplin syncing webdav to my email service to cross my devices.

Active development and great UX:

I use Loop Habit Tracker for tracking activities and notebook for journal. Tried standard notes, Joplin and obsidian too. Its simple to use notebook instead of apps.

I can’t find open source habit trackers with mood trackers.
