SilentNotes
What it is
SilentNotes is a free, open-source note-taking app for Android and Windows, with offline writing and synchronization options. Its editor supports basic formatting such as headers and lists without markup, and notes can be tagged, searched, or filtered. Touch-oriented to-do lists can be reordered. The app stores notes locally and works without an internet connection; synchronization is available through FTP, WebDAV, Dropbox, Google Drive, and OneDrive, including a user's own online storage. Notes are encrypted on the device before synchronization. A password-protected safe stores notes encrypted locally, using a 256-bit key and Argon2id by default. Unprotected notes are usually readable on the device. The maker says the app has no ads and does not collect personal data. Automatic backup is disabled on Android and Windows, so users must handle backups themselves. Android requires version 7.0 or later, and Windows requires version 10 version 1809 or later. The free plan has no listed limits.
