Some comments / suggestions
WPS:
Closed source and Chinese. You have to ask why they're offering their product for "free". That makes me suspicious enough not to want to install their software on my PC. Plenty of other Freemium software from China has proved insecure / privacy-invading (e.g. Maxthon). Libre Office is preferable in all regards and Only Office covers more ground for Microsoft compatibility.
Notion:
No Android app (what are they smoking?) and the pricing is very high if you're just one person.
Typora vs Mark Text:
Typora is nice, but will be free only during beta. For a similar open source app, see Mark Text. Another one to check out is Ghostwriter.
If you rely on a service to store your data, you should know that they can read your stuff if they don't use "zero-knowledge" or "end-to-end" encryption. Without this, they can also be forced to give your data up to government surverillance programs and your information is readable to any hackers that manage to breach the servers on which your stuff is stored. Here are some suggestions for writing apps that offer encryption and therefore cannot read or give away your data.
Collaboration + Encryption?
See Cryptpad. Open source, of course.
Encrypted html-based text editor
Try Airborn. It looks like Word, but it saves your stuff in .html format. Open source, as always.
