Motivation for building this app

As someone who enjoys writing in a diary, I've tried out many diary apps on Google Play. Through my own experiences and by reading what others have shared in their reviews, I've gained a better understanding of the issues that current diary apps face.

• Requires premium subscription for seemingly simple features
• Lack of proper authentication: In some cases, users have to enter their password every time they log in, as there is no support for fingerprint authentication
• Ads are the last thing you want to encounter while writing; just picture yourself composing a thought-provoking entry, and an ad suddenly appears, disrupting your train of thought
• No support for images
• No automatic saving: People don't want to lose their lengthy notes just because they ran out of battery, received a phone call or clicked on a notification
• No font customization for overall app and individual note level
• No customizable sorting: Not everyone wants to sort by date

For Contributors: Adding/Updating Translations

We have an automated translation system that makes contributing translations easy:

cd python
./setup.sh
source venv/bin/activate
python translate_all.py --dry-run  # Check what's missing
python translate_all.py            # Generate all missing translations

The script discovers all intl_<code>.arb files in lib/l10n automatically, so new languages are picked up as soon as the file is added. For detailed instructions, see python/README.md.

Features Planned for Future Releases

• Add OneDrive as a cloud backup source.
• Organize notes using smart folders.
• Add support for stickers within the editor.
