  • Standard Notes

    Freemium Mac Windows Linux Web Android ... iPhone Chrome OS Android Tablet iPad Self-Hosted Website

    Standard Notes is a simple and private notes app. It allows you to write and sync your notes across all your devices, including your iPhone, iPad, Mac, and web browser.

    Private means your notes are end-to-end encrypted, so only you can read your notes. Even we can't read the contents of your notes.

    Simple means it does one job and does it well. Standard Notes is a safe and lasting place for your life's work. Our focus is making it easy to write notes wherever you are and syncing them with encryption to all your devices.

    Standard Notes comes free with:
    • Seamless sync across all your devices, with easy to use applications on iPhone, iPad, Mac, web browsers, and other platforms.
    • Offline access, so you can access your downloaded notes even without a connection.
    • No limit on number of devices.
    • No limit on number of notes.
    • Passcode lock protection, along with Touch ID and Face ID protection.
    • A tagging system to organize your notes (like #work, #ideas, #passwords, #crypto).
    • The ability to pin, lock, protect, and move notes to trash, which allows you to recover deleted notes until the trash is emptied.

    We made Standard Notes simple because longevity is important to us. We want to make sure we're here, protecting your notes, for the next hundred years. You shouldn't have to find a new notes app every year.

    To sustain our development, we offer an optional paid program called Standard Notes Extended. Extended gives you access to powerful tools including:
    • Productivity editors
    • Beautiful themes
    • Powerful cloud tools including daily backups

    You can learn more about Extended at standardnotes.org/extended.

    We're always happy to talk, whether it be a question, thought, or issue. Please feel free to email us any time at help@standardnotes.org. When you take the time to send us a message, we'll be sure to do the same.
