Two pieces of software,
one chain of custody.

The mobile app seals the evidence at capture. The desktop validator lets anyone — including the opposing party — verify the bundle offline, on any operating system.

Desktop validator

For anyone who needs to verify

Locus Validator is the standalone, open-source desktop counterpart of the mobile app — built with the same stack. It recomputes every cryptographic check locally and runs fully offline, with no account required. When a bundle fails and you are online, it can additionally cross-check it against the authoritative server record to pinpoint exactly what was altered — file, hash, signature or timestamp; the only thing it ever sends is anonymous telemetry of validation outcomes — never your identity or the evidence. And if you would rather install nothing: every bundle is self-verifying — it ships with verify.sh/verify.bat and an interactive.html report with in-browser hash validation.
