Open Source Microsoft OneNote Alternative
Using OneNote? Try Notesnook and go 100% private
End to end encryption
Notesnook is by default private. Enjoy rich and powerful note taking while keeping your notes 100% end-to-end encrypted. If you use OneNote online, you have to trust Microsoft that they won't misuse your data. With Notesnook it's impossible for us or any third party to read your notes.
Never risk your privacy again
No matter how many times Microsoft tells you that they respect your privacy and won't read or access your notes. As long as your notes are not encryped, they are always at risk. So any employee at Microsoft OneNote or the government can get access to them anytime they want. Because they can.
A key to a door that can be broken
Imagine a Microsoft server get's hacked. All your notes & data can be easily accessed and used for what not. Even with the best security, there's still a possibilty of a data breach. Therefore Notesnook encrypts your data. No one except you can read your notes. It's just impossible.
