NoteSR

What NoteSR is
NoteSR is a free, open-source Android note-taking app designed for offline storage. It keeps notes in encrypted space on the device and works without cloud storage or an account. The project says content uses AES-256 encryption, and no data leaves the device without the user’s intent. You can write text notes, attach files, and open attachments in the built-in viewer. Images, videos, and text files are listed as supported basic file types. Encrypted backups can be exported and imported, with the user’s key required to open them. A cross-platform command-line tool is linked for working with those backups. The project offers an APK through GitHub releases or source code for building. NoteSR is suitable for journaling, personal records, and secure attachments. Its privacy policy says it does not collect, store, or share user or device information with third parties. Version 5.6.0 is the latest listed release.
