Download FAQ

Why isn't Y Communicator on the Google Play Store?

We offer a direct APK download to provide maximum privacy. Play Store distribution requires Google services integration that could compromise user privacy. Our direct download ensures you get an app free from any third-party tracking or dependencies.

Why is iOS only available through TestFlight?

Y Communicator is currently in beta testing. TestFlight allows us to distribute beta versions to iOS users while we finalize the app for App Store release. Once testing is complete, we'll submit to the App Store for general availability.

Is it safe to install from "unknown sources"?

Yes, when downloading directly from our official website. Always verify you're on www.y-communications.com and check the SHA256 checksum of the downloaded file. This ensures the APK hasn't been modified by a third party.

How do I update the app?

For iOS: TestFlight will notify you of updates automatically. For Android: Check this page for new versions and download the latest APK. We'll notify you within the app when updates are available.

What data does the app need access to?

Y Communicator requires minimal permissions: camera (for QR codes), microphone (for voice messages), local notifications (for alerts), and network access. We never access your contacts, location, or any other personal data.
