Secure device-synchronized notepad
A safe place to keep your notes, confidential data, and credentials


End-to-end encrypted sharing
We wanted to be able to share and collaborate on confidential notes with people we trust:
- You can share a single note or a branch of notes with multiple trusted people
- Any changes within the shared note or its subtree are automatically synchronized between participants
- Data is encrypted so that only participants can decrypt the data in the shared notes

Secure and Open Source
We wanted to be able to store any kind of data (whether personal, confidential, or credentials) and know it is safe. Here's how:
- Everything is AES-GCM-256 encrypted before it leaves your device
- No one can read your data: not us, not our servers, and not your ISP
- All the code is open source under GPLv2, ensuring security is transparent
- We prevent accidental screen sharing by hiding Mimiri Notes from screen sharing programs
- We prevent onlookers and security cameras from seeing passwords by hiding them from plain view
- Optionally lock the application when it has been unused for a while

Well-organized
For us, a key design principle was always that as a user, you should have complete freedom in how data is organized. This is how we achieved it:
- A tree structure allows endless nesting of notes within notes
- Notes can be easily moved around and reorganized
- Quickly narrow down the tree using search to find a specific note
- Nothing is just a folder: any note can contain data as well as sub-notes

Any device
We wanted to be able to access our data from anywhere and have it synchronized in real-time:
- Clients are available for all major platforms (see Downloads)
- All data is cloud-synchronized and pushed to your other devices in real-time
- A local copy of your data exists on your device, granting full access even when offline
- Our web client allows access from any browser, even if you are without any of your devices

Robust
Data and changes must be safe, even if mistakes are made:
- Any edit you make in any note is tracked, and you can easily view and restore historical changes
- Deleted notes are first moved to a Recycle Bin, preventing accidental deletion of data
- All data is also stored on your local device and can be accessed even when offline
This ensures that your notes are always safe, even if you happen to delete or edit something by mistake, or if our servers were to go away.

Optimized for productivity
Mimiri Notes is designed as a support application, so you can go about your daily work while quickly taking notes or copying and pasting content.
To support this, we believe in a simple and clean interface without too many distractions or advanced layout features. This is also why it's designed to sit always ready in your system tray.
We believe this aspect is a big part of what makes Mimiri Notes great and sets it apart from other applications out there.
