In 2019 most people’s data is held across cloud providers, free to be sold or subpoenaed at any time.
Here are my personal choices to limit this, be it in vain or not it helps me sleep better at night.
Use Proton Mail, emails are decrypted in the browser using your key (password). iOS & Android apps.
Downsides: Limited features, apps only allow single user login at once.
File syncing
Use Tresorit, end-to-end encrypted. Unlike similar services this one has a decent mobile app for iOS and Android devices so you can sync & backup your Photos automatically.
Calendar syncing
Use a self-hosted Next Cloud running with the Calendar app enabled. This will give you a CalDAV server which most Calendar applications can sync with.
Note taking
Use Standard Notes, end-to-end encrypted syncing with apps for Mac, Windows, Linux, iOS, Android.
VPN
If you don’t want to host your own VPN then use iPredator. Founded by Peter Sunde this is the only provider I would consider trusting.
If you’d like to host your own, use Algo.
Password management
Use LastPass, end-to-end encrypted with plugins for Firefox, Chrome & Android.
Instant messaging
Use Signal, end-to-end encrypted by default, unlike other services.
