What SilentNotes is

SilentNotes is a free, open-source note-taking app for Android and Windows, with offline writing and optional synchronization. Its WYSIWYG editor supports basic formatting such as headers and lists, while notes can carry multiple tags and be searched or filtered. Touch-oriented to-do lists can be reordered. Notes are stored locally, and the app can sync through FTP, WebDAV, Dropbox, Google Drive, or OneDrive, including storage users manage themselves. Notes are encrypted on the device before synchronization. The password-protected safe stores its notes encrypted locally and uses a 256-bit key with 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 backups are disabled on both supported platforms, so users need to manage their own. JEX is listed as an export format. Android requires version 7.0 or later, and Windows requires version 10 version 1809 or later.
