IO Notes is a hipster kind of note-taking app. It's not a replacement for the popular note-taking app you're probably currently using.

IO Notes will always be a lean, minimalist, and extremely configurable note-taking app, and only for security and privacy minded people.

Notes created using IO Notes are secured using industry standard AES encryption, and stored inside a database file which is encrypted using the same standard.

Access to IO Notes is always password protected. Note that forgetting your password simply means losing access to your notes. There's no way to recover your password. Consider yourself warned!

Whether your notes contain sensitive information or not, it doesn't mean you should allow others to have their eyes on your notes easily.

Features:
- Encrypted notes
- Encrypted database
- Password protected access to app (optional is never an option for this)
- Free (as in beer)
- Ad-free (forever)
- Dark and Light theme
- Zen Mode for distraction-free note-taking session
- Alarm (sound, vibration, LED with color choice)
- Minimum password length configuration
- Backup and restore
- Font type configuration
- Font size configuration
- Color (assign color to note)
- Filter (base on colors and tags)
- Share (send and receive text data between installed app)
- Tags
- Export/Import

Planned features:
- Attachment (any file type)
- Cloud sync (In-App Purchase)
- Landscape layout
- Tablet layout
- Soothing audio in Zen Mode

Encrypted content (within encrypted database):
- Note's title
- Note's content

Plain text content (within encrypted database):
- IDs
- Date time information
- Alarm's message
- Color code
- Tag

Warning:
Alarm's message also duplicated on your device in plain text format, unencrypted. This is necessary to make sure alarms are set properly across device reboot. Exercise caution to not leak note's content in alarm's message.

Translation:
- German (Christian Orjeda)
- Spanish (Christian Orjeda, Paco Inurreta)
- Indonesian

Permission explanation:
RECEIVE_BOOT_COMPLETED: To set alarms across device reboot.
READ_EXTERNAL_STORAGE: To list available backup file.
WRITE_EXTERNAL_STORAGE: To create backup file.
VIBRATE: To vibrate the device when an alarm sets off.

If you'd like to see a planned feature prioritized, or a feature not on the list, I encourage you to request it via Feedback menu from IO Notes app.

IO Notes only supports devices running Android v4.0+. It is tested on:
- LG Nexus 5 (OmniROM, Android v.4.4.4)
- Samsung Galaxy Note II (N7100, Stock/OmniROM, Android v4.4.2)
- Samsung Galaxy S (I9000, CyanogenMod, Android v4.4.2)
- Asus Nexus 7 (2013 WiFi, AOSP, Android L Preview)

"O monstrous world! Take note, take note, o world, to be direct and honest is not safe!" - William Shakespeare

Thumbs up
Great idea! Do you consider to release the source code? Are you planning to add features to encrypt pictures too?

Well, the idea is to be able to encrypt all kind of data given to it, be it pictures, videos, or any other files. I plan to work on it after all items under `Next features` are off the list. But then again, if many people requested specific feature via Feedback menu, I'll prioritize it.

In the near future, the source will not be released to public. But there's always a possibility for that in the future, depending on various circumstances.

Just to give some feedback. It works great one the HTC One. (4.4.2).

I'm probably picky but maybe go with a sans serif font.

Sure, font type and size options will be there in the coming few updates. Thank you for letting me know.
