What SilentNotes is
SilentNotes is a free, open-source note-taking app for Android and Windows. It supports writing notes offline and synchronizing them through FTP, WebDAV, Dropbox, Google Drive, or OneDrive, including storage users manage themselves. Its editor offers basic formatting such as headers and lists, and notes can have multiple tags or be searched by their text. Touch-oriented to-do lists can be reordered. Notes stay on the device when offline; before synchronization, they are encrypted on the device for transfer. The password-protected safe stores its notes encrypted locally, using a 256-bit key and Argon2id by default. Unprotected notes are usually readable on the device, so local storage is not encrypted by default. The maker says the app has no ads and does not collect personal data. Automatic backup is off on both supported platforms, leaving users responsible for their own backups. The free plan costs nothing.
