Open source notes app with end-to-end encryption
Standard Notes is an open source note-taking app focused on privacy, with end-to-end encryption for every note and file and apps on all major platforms. Notes work offline and sync across devices, and paid plans add rich editors, file storage and longer revision history. The company became part of Proton in 2024, and the sync server can be self-hosted.
