Open-source notices

GroupYid is built with open-source Android, Kotlin, Node.js, and web components. Exact versions and integrity hashes are locked in the source distribution. Applicable licenses and service terms remain with their respective authors and providers.

Android Open Source Project MMS codec attribution

GroupYid's bounded MMS codec uses constants and WSP/PDU encoding structure derived from the Android Open Source Project Messaging mmslib implementation. Its automatic-download response flow and Retrieve-Status retry ranges follow AOSP Messaging's public-API integration.

Dependency inventory

The Stage 1 Android app uses AndroidX, Kotlin, coroutines, JUnit, and JSON-java. It does not ship Firebase Authentication, Google identity, Credential Manager, or Play Integrity. This static site uses TypeScript, Vite, Vitest, and their locked build dependencies. The isolated future API prototype has its own locked Fastify, Google Cloud, JOSE, and Zod dependencies and is not part of the app or public website. Release preparation includes an exact transitive license review; this page does not replace license text packaged with distributed software.
