IO Notes

流行に敏感なノート作成アプリの一種で、唯一のセキュリティとプライバシー志向の人のために。

IO Notes is 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

Planned features:

- Attachment (any file type)

- Cloud sync (In-App Purchase)

- Landscape layout

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.
