Very good your hunting @samsolrizal, with this your privacy will be better than ever. Here I will leave you my PROS and CONS for this hunt.

Pros:

• You can forget about protecting your files in the cloud with passwords since cryptomator uses point-to-point encryption and the best thing is that it does not have a known back door yet.
• It is completely multiplatform since it is available for mobile devices (Android, iOS), Linux, MacOS, Windows. It is also extremely light in all its versions.
• It has a very good graphic interface and is easy to use.

Cons:

• Its price is somewhat high, considering that there are free applications with the same function.
