Phantom Chat

A milestone I'm proud of as a solo founder. I built Phantom Chat — an anonymous, post-quantum-encrypted iOS messenger — on my own. Today I did something most companies never do with their security claims: I published the cryptographic core for public review. Anyone can now read the actual encryption code, and the automated tests run on Apple's own hardware — including a byte-for-byte conformance check against Apple's own implementation of ML-KEM-768 (the NIST post-quantum standard). I also published an audit that maps every privacy claim on my website to the exact source file behind it — and openly documents the parts that are still partial, and the metadata the server can see. No spin. Why do this? Because "trust us, it's private" isn't good enough for a privacy product. Verifiability is the only honest standard. It's source-available under a review license (not full open-source yet), and it's in TestFlight beta. I'd genuinely value scrutiny from the security and engineering community.

New in this build: I thought I had done a few of these fixes and features but they must have slipped my mind, Anyways they have been fixed now so everything is still on track hopefully for a early July release. **Send files, not just photos** — tap the paperclip and choose "File" to send audio, PDFs, or documents. Everything is end-to-end encrypted exactly like photos. Audio plays right in the chat with a play button; other files open with a tap. **Photos no longer leak your location** — every photo and video now has its GPS/location and camera info stripped automatically before it's sent. The person you send to can't see where it was taken. This is true anyway as you cannot save anything in the app. **Disappearing messages now also clear from our servers** — when a timer expires, the message disappears on your devices *and* the encrypted copy is automatically deleted from the server shortly after. **Verification stays on your device** — when you verify a contact or group's safety number, that choice now lives only on your phone and is never sent to our servers. Plus behind-the-scenes reliability and security clean-ups. **Please test:** 1. Paperclip → File → send an audio file (it should play inline), and a PDF (it should open). 2. Send photos and videos in 1-on-1 and group chats — confirm they still send and view fine. 3. Set a short disappearing-message timer and confirm messages vanish on time. 4. General messaging, groups, invite codes, and app lock — let me know anything that feels off. Thanks for testing — reply in TestFlight or email [email protected] with any bugs.

Hey team — big update just went up on TestFlight, Also just to inform everyone that the pricing is in US dollars, so if you are testing the founders wave it is $299.99 in the US and $499.99 in Aus, Same with the personal subscriptions. This build turns on the subscription paywall (this is how Phantom Chat will work at launch). You will NOT be charged anything — TestFlight runs purchases in Apple's free "sandbox," so the 14-day trial and the Founder purchase are completely free to test. When the paywall appears, just tap Start 14-day free trial (or Become a Founder if you want to try that flow). Founders get a permanent Founder #N badge that shows next to your messages. Heads up: this build removed the old tester bypass, so everyone sees the paywall now — that's intentional, it's what real users will see. We fixed a bunch of things today and I'd love you to hammer on them: • Typing indicator no longer gets stuck on "…is typing" • Keyboard no longer pops up over the lock screen • Founder badge now shows on your own messages + in Settings • Manage/Cancel subscription button now works • Paywall price shows your correct local price (no weird flash) • Group join/leave and message sync (no "encryption out of sync") If anything looks off, hit the TestFlight feedback button (a screenshot + "here's what I did" is gold). Thanks for helping get this to the finish line PS: Feel free to try the Founder flow — it's a free sandbox purchase and won't carry over to the public app, so you'll re-subscribe there This will probably be the last beta test unless something unusual happens in the app. A big big big thank you to all the beta testers.
