Hello!
This post aims to suggest a native Android app that I am loving: Markor.
Text editor - Notes & ToDo (for Android) - Markdown, todo.txt, plaintext, math, …
- GitHub
It is a local, open-source, and privacy-focused notebook; in fact, it works offline (not completely, for example: when you reference an external image via URL).
It supports many formats:
Markdown
todo.txt
Zim
/WikiText
Plaintext
csv
ics
ini
json
toml
vcf
yaml
And with the latest updates, it also supports: AsciiDoc
, CSV
, Org-Mode
.
Encryption
Markor includes optional file encryption with AES256
.
Can encrypt your text files with AES256. You need to set a password in the settings and use an Android device with version Marshmallow or newer. You can use jpencconverter to encrypt/decrypt on desktop. Be aware that only the text is encrypted, not pictures or attachments.
- GitHub
Any minor issues related to the implementation of encryption are not a real problem (for me), as the files are stored on the device, which hopefully is not compromised ;).
Synchronization
The application does not allow direct synchronization, being offline… but since the files are saved in user-selected folders, secure and reliable software like Syncthing works well for synchronization (with E2EE) across all devices (Windows, Linux, etc.).
In conclusion
- Open-source
- Offline
- No data collected
- Encryption
AES256
(optional) - Maintained and well documented
The software is fast (I haven’t tried it on a tablet), written in Java
, maintained, and well documented. I love it because I feel I have full control over my files. I highly recommend it. Thank you gsantner <3
To discover all the details, visit the GitHub repository. I have nothing to do with the project; I don’t even know how to program in Java!
