ScreenGuardian™ is the proprietary work of Eric W. The product bundles and links against the third-party components listed below; each is governed by its own license. The same attributions are also bundled inside the desktop app under Help → Third-party notices, so they are available offline.
If you believe a component is missing from this list or that an attribution is incorrect, please contact screenguardian.info@gmail.com.
The ScreenGuardian desktop app is built on the Qt framework via the PySide6 Python bindings. Qt is dual-licensed under commercial and LGPLv3 terms; ScreenGuardian uses Qt under LGPLv3.

Each transitively included Python package keeps its
LICENSE / NOTICE /
licenses/ metadata inside the packaged
_internal/<package>.dist-info/ directory
shipped with the desktop app. Notable transitive dependencies
pulled in by MediaPipe include
jax, flask, click,
pydantic, requests,
regex, jsonschema,
importlib_metadata, and the
opentelemetry family — each under their
respective open-source licenses.
Note on OpenTelemetry: it is present in the bundle as a transitive dependency of MediaPipe but is not initialized by ScreenGuardian. No telemetry exporter is started by the app or by its detection code.
Used for the WebGL monitor on the homepage. github.com/mrdoob/three.js.
Account, entitlement, and download functions run on Supabase's Deno runtime. The runtime and platform-provided libraries are governed by the Supabase, Deno, and Postgres license terms. No additional third-party libraries are bundled inside the function code itself.
