SilentNotes is a note taking app which respects your privacy. The notes can be synchronized between Android and Windows devices. SilentNotes uses end-to-end encryption to protect the notes.

More information you can find on SilentNote's homepage.


  • ✔ Take your notes wherever you are on your Android and Windows devices.
  • ✔ Quickly find the right note with the full-text search, just by typing a few letters.
  • ✔ Store the notes to an online-storage of your choice, this allows to synchronize them between devices and offers an easy backup.
  • ✔ Currently supported are the FTP protocol, the WebDav protocol and Dropbox.
  • ✔ The notes never leave the device unencrypted, they are end-to-end encrypted and can only be read on your devices.
  • ✔ Use basic formatting to structure your notes and make them more readable.
  • ✔ Get a note back from the recycle-bin if it was deleted by accident.
  • ✔ SilentNotes does not collect user information and requires no unnecessary privileges.


Whenever an application promises security and confidentiality, users just have to trust the developer team. Not only is it challenging to do encryption right, users are more and more used to pay with their personal data, to benefit from new technologies. We believe that the best way out of this dilemma is to publish the entire code, this is why SilentNotes was turned into an open source project.


  • The QuillJS library made it possible to offer WYSIWYG note editing across platforms.
  • Cryptograhic tasks are solved with the Bouncy Castle crypto API.
  • The ordering of notes is done with the SortableJS library.
