twonlyapp/twonly-app ? reverse-engineered prompt

Build me a mobile app like Snapchat, but privacy first. I want people to be able to sign up without an email or phone number, add friends, and send photos, videos, text messages, and voice notes in one on one and group chats. It should support disappearing media with timers, stories that expire after 24 hours, live location sharing, custom stickers, a few simple mini games, and a memories view with a map and encrypted cloud backup.

Make the whole thing feel fast and polished, with a simple camera flow and lightweight editing tools. Keep everything end to end encrypted, with no ads, no tracking, and no data selling. Also include features for account recovery through trusted friends and privacy friendly friend discovery. Build it as a cross platform app for iPhone and Android, and if you need to look up current docs online, go ahead.
