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.
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.
Use Standard Notes, end-to-end encrypted syncing with apps for Mac, Windows, Linux, iOS, Android.
If you’d like to host your own, use Algo.
Use LastPass, end-to-end encrypted with plugins for Firefox, Chrome & Android.
