Is it Open Source?

TopSecret Chat's core-engine is a proprietary technology, not released under an Open Source license.
The Android and iOS packages are signed for authenticity and the server-code is deployed encrypted to avoid tampering and elude mass-surveillance programs. If you choose the anonymous download of the Android APK from our server, please verify the integrity of the SHA256 File Checksum.

However, we also reference some Open Source projects that are naturally exposed and available to the users for inspection.

We operate with the Zero Trust security model for complete protection.
