Standard Notes

Standard Notes is a free, open‑source note‑taking application that stores all content with end‑to‑end encryption. Only the user possesses the keys needed to decrypt notes and attached files, and the encryption implementation has been audited by third parties. The service offers a range of editor types—including markdown, rich text, code snippets, and outlines—so users can capture anything from simple thoughts to complex documents while keeping the data private.

The app synchronizes automatically across an unlimited number of devices, providing offline copies of all notes and files for access without an internet connection. Backups are performed securely in the cloud, protecting information against loss, device damage, or theft. Users can also store sensitive material such as passwords, legal contracts, health records, and personal finances within the same encrypted vault.

Designed for individuals who need strong privacy guarantees—such as digitalists, professionals, and anyone handling confidential information—Standard Notes combines cross‑platform availability with zero‑knowledge security, allowing users to write and organize their data without fear of unauthorized access.
