I thought of a similar thread but I think the results would be pretty much the same. It's great to have some mutual inspiration here.

Anyway, there's tons of stuff I can list here. I'm gonna list some stuff but will probably forget 70% of the other stuff because it's become so common in my daily life.

• Own NAS as private cloud
• Self-host on my NAS to not use internet services that spy on me (like Bitwarden, Joplin server, cryptgeon, Syncthing, Nextcloud)
• OPNsense as my router of choice
• W10Privacy (because I still can't switch to Linux because of circumstances)
• Firefox as my browser of choice with some extra settings to harden it (I tried something like LibreWolf in the past but I can't use Spotify without DRM)
• uBlock Origin of course (and some other browser addons like LibRedirect, ClearURLs, Decentraleyes and so on)
• Privacy respecting mail provider (mailbox.org)
• Signal (instead of WhatsApp)
• Thunderbird (instead of something like Outlook)
• Piped (instead of YouTube)
• Uninstalled/disabled all apps on my phone that I don't need (also saves battery)
• Been using custom ROMs on my phone (but I made some bad experiences with stability so I stick with the stock ROM for now)
• NextDNS (with encrypted DNS)
• Whoogle (instead of Google)
• Lemmy (instead of reddit, haha)
• Avoid accounts (and even links) to something like Facebook, Instagram, TikTok and so on
• Libreddit, Nitter and all the other privacy friendly frontends for social media
• Never connected devices to my LAN/Wi-Fi that don't need an internet connection (like a stove lol) and never installed the apps on my phone to operate them

Gonna add some more to the list whenever something comes up in my mind. Like I said it's become so basic in my life that I don't always think about it anymore when I use it.

Btw things like 2FA only help with security, not privacy.
