I moved away from Google a few years ago. I'm using the following alternatives:
- Email: ProtonMail
- Contacts, Calendar, Online storage: NextCloud hosted by Hetzner (https://www.hetzner.com/storage/storage-share)
- Phone: LineageOS (Android)
-- App stores: F-Droid for most apps and Aurora store for the occasional non F-Droid apps (like the ProtonMail client)
-- Maps: MagicEarth (not open source but privacy friendly and very featureful)
-- Messaging: Telegram FOSS
-- Contact & Calendar sync: DAVx
- Notes: Joplin (syncs with NextCloud and available on F-Droid as well)
- Search: DuckDuckGo
ProntonMail (with own domain) and the hosted NextCloud instance aren't free, but privacy comes with a price and I'm happy to pay for it. So far I'm very happy with the transition.
