GSTNet Secure: Encrypted chat and calls with no phone number needed

Hi Product Hunt! 👋 I built GSTNet because I was tired of handing out my phone number to everyone I met online, from buyers and clients to people I met while traveling. With GSTNet you sign up with just an email and get an 8-digit GST-ID. Share that instead of your number. 🔒 Messages, calls and files are end-to-end encrypted. We don't have the keys to read them. 🌍 On iPhone and iPad, incoming messages can be translated into about 20 languages, right on your device. 📞 Voice, video and group calls, connecting device-to-device when possible. 💻 Works on iPhone, iPad and Windows. Every feature is free for 90 days, with no credit card. I'd love your honest feedback: what would make you switch from the messenger you use today?
