kardi notes | privacy matters

Application for taking notes with capabilities to view all content from any device while keeping all data accessible by you only. The app is designed to run on all modern operating systems including Windows, Linux, Android, MacOS and iOS along with a web version accessible directly from any browser. Download on your phone, save important information, download on your computer, easily pair the applications and enjoy your content from anywhere!

All data you enter into the app is securely encrypted before being sent to server and you are the only person with capabilities to decrypt them. Full encryption process:

- 1. your note in plain text

- 2. optional AES128 - you set password to selected note which is then used as an encryption key (the password is sent to server hashed using sha256)

- 3. AES256 - encryption key based on your owner key (the owner key is sent to server hashed using sha256 and can be encrypted locally with a password)

- 4. AES256 - encryption key is different for each session and is generated using Diffie-Hellman key exchange (server logs are being purged frequently)

No ads, no telemetry, no logs.

In case of somebody taking control of your device, they might be able to access your notes, however there is an option to have whole application password locked.

Application is easy to use, mostly self explanatory with hints and example in case you get lost. Please note, if you forget your password or lose your device, all your data is lost and cannot be recovered. App contains multiple safe mechanisms to prevent undesired behaviour such as overwriting notes that have been changed from other device.
