Hi PH 👋 I'm Curtis — solo founder, Western Australia. I've been building Phantom Chat for 8 months and just opened the public TestFlight beta. Three things I designed it around: 1️⃣ Post-quantum from day one — hybrid Signal Protocol + NIST FIPS 203 ML-KEM-768 (Kyber). Most messengers still don't have this; we ship with it from launch. 2️⃣ Anonymous sign-up — no phone, no email. Just pick a username. Contact discovery is invite-code-only. 3️⃣ Hardware-bound identity — your private key lives in the iPhone's Secure Enclave and never leaves it. Free 14-day trial, no card. After that: Personal at US$14.99/mo or US$119/year. TestFlight: https://testflight.apple.com/joi... Always happy to answer technical questions — and if you spot something the marketing site overpromises, please call it out. I've already removed three claims that didn't quite match the code (Sealed Sender, iMessage PQ comparison, "air-gapped" servers) — I'd rather get those right than ship spin.
