I use the Cryptomator app for this, it works as advertised. I keep ~60 GiB of personal files in there that would be an easy button to steal my identity and savings. I'm just hoping it doesn't include an NSA back door.

Even if I had the skills to confirm the code is secure, how could I know that this is the code running on my phone, without also having the skills to build and deploy it from source?

		Also, you need to make sure that the installation process does not insert a backdoor into the code you built from source.
