zM SOS GUARD is a forensic Android recording protocol. I built it for journalists and activists who need absolute data sovereignty.
No cloud, no bloat, no tracking. The 500Kb APK uses native code to fragment video into 20s blocks, pushing them directly to your private Python server. Designed to bypass battery kills and ensure forensic persistence (tested up to Android 16).
Fully open-source, auditable, and built for transparency. Check the source on GitHub and see the documentation on my site.
