Enhancing Online Privacy: Seeking Additional Tips and Recommendations

I'm using the following tools for online privacy:
- Ad blocker
- DuckDuckGo as search engine
- Brave as web browser
- Notesnook for notes
- KeepassXC with Yubikey for password management
- Filen.io for cloud storage
- Following the GitHub repository: https:// github.com/Lissy93/personal-security-checklist for tips
- And this one https://github.com/the-weird-aquarian/privacy-settings/
Is there anything else I can do to further improve my privacy online?
