Zero cloud. Absolute sovereignty.
A markdown-based research tool built for high-risk reporting. Your database is encrypted locally with AES-256 before it ever touches storage.
Uncompromising local architecture
AES-256 Encryption
Zero Telemetry
Plain-Text Portability
Your database is locked at rest using zero-knowledge XTS-AES-256. We do not hold your keys because we do not have a server.
No background pings, no crash reports, no tracking cookies. The application runs entirely isolated from the network.
Your notes are saved as standard markdown files. No proprietary databases, no vendor lock-in. Your data remains yours forever.
Independent security audits
We submit our entire codebase to third-party cryptographic audits annually. Our format is fully open-source, allowing any agency to verify our claims.
Audit v2.4
Conducted by independent cryptographic experts. Zero critical vulnerabilities were found in our local database encryption or key derivation routines.

Frequently verified details
How are encryption keys managed?
Can I sync across my devices?
Your master key is derived using Argon2id and stored in your operating system's secure keychain. We have no access to it.
Yes, but only via your own self-hosted solutions like PGP-encrypted Git, Syncthing, or local network drives. No cloud required.
What happens if I lose my key?
Is the file format open?
Because we run a zero-knowledge architecture, we cannot recover your data. Keep your physical backup phrase secure.
Completely. Outpost writes plain markdown files organized in standard directories. You can open them in any text editor.
