I'm looking for an application for keeping a personal diary on my Android phone. My requirements:
- All data is encrypted so that only I can access the content.
- It's open-source (I have higher trust to open-source solutions when it comes to security).
- The content is replicated to a cloud storage like Google Drive so that losing my phone doesn't mean losing all my data.
Other than that, no special features are needed, just writing text (or perhaps dictating) on a daily basis.
