Motorola isn't officially available in my country and judging from the Pixel 11 the direction Google is moving in, I won't be able to use GOS after about 7 years if they continue stripping security features from their already mediocre chips
My current markdown app on Android is Markor, but it stores notes outside its app sandbox. Moving forward, I'll have to try building a notes app that contains all the notes in the sandbox and exports in an encrypted zip/7zip format. I hope I'll be able to encrypt the app itself with a unique key (not the device key).
If done right, I'll no longer be at the mercy of my phone's OS and whether they choose to implement a Private Space/Secure Folder. All I have to do is make sure it has a decent secure element... This will be extremely difficult as someone with no experience in Kotlin and coding in general
