Zero-knowledge markdown editor.
A local-first, offline-encrypted writing environment built specifically for high-risk field reporting. Your notes remain on your hard drive, protected by military-grade local keys.
Built for the field.
Local-first storage
Offline encryption
Zero telemetry
No remote databases or third-party servers. Your files are saved directly to your local disk in standard, readable markdown format.
Every note is locked with zero-knowledge AES-256 encryption. We have no cloud, no passwords, and absolutely no way to access your data.
No background tracking, no crash reports, and zero network requests. A completely isolated writing environment that respects your digital perimeter.
Absolute local data sovereignty.
Mainstream note apps compromise security for convenience. Outpost is built on the radical premise that your writing should never leave your physical machine without your explicit consent.
