I recommend Notesnook. It is open source, cross platform, and cloud synchronized E2E encrypted. I know cloud based wasn’t something you wanted especially, but I thought it was worth mentioning because it is encrypted.

I personally like flatpak and its build system. Flatpak applications are sandboxed by default and don’t require root during any part of installation, reducing the risk of malicious/broken software damaging the host. They also are available for basically any base distro, meaning i can use the same apps if a ever distrohop and i can even just copy over the config folders as if nothing happened.
Not really needed on Android or in general. If all you want to know is whether your system is compromised, use Auditor by GOS.
