I’ve been degoogled for a little bit over a year now and here’s what I use (disclaimer: I own a NAS / homserver, so I got a little bit more options than most people would).

• Android OS: /e/OS
• Browser: Firefox and Bromite
• Maps: Organic Maps
• Play Store: F-Droid (droidify client in my case) and App Lounge.
• YouTube: Libretube (privacy-friendly YouTube client)
• Translation: DeepL
• Movies, TV Shows, Music: self-hosted Jellyfin
• Automatic backup of my images and videos: self-hosted Immich
• VPN server: self-hosted Wireguard server
• Document management: self-hosted Nextcloud Office + LibreOffice on my PC
• E-Mail service: ProtonMail (self-hosting this is a pain in the ass, so I’ll just leave it to experts)
• Search engine: DuckDuckGo
