About this app

BombaChat is a Quantum resistant, end‑to‑end encrypted anonymous chat app designed for people who want simple, private messaging without accounts, phone numbers, or email. Instead of tying your identity to a SIM card or social profile, BombaChat generates a random user ID on your device. You share this ID with someone you trust, create a password for the chat, share the password, and you can immediately start a secure 1‑on‑1 chat.

Under the hood, BombaChat uses a modern hybrid cryptographic design that combines classical elliptic‑curve keys (X25519) with post‑quantum ML‑KEM key encapsulation, plus HKDF key derivation and AES‑GCM message encryption. This means your conversations are protected today and are designed to remain secure even in a future where large‑scale quantum computers exist. Every conversation uses fresh key material, and messages are encrypted on your device before they leave it and decrypted only on the recipient’s device.

To further protect your privacy, messages are automatically deleted after they have been read, reducing the amount of chat history that ever exists on any device or server. BombaChat relies on Firebase only as a delivery channel for encrypted messages; the service never sees your plaintext content or usable keys. The app supports anonymous sign‑in, so there is no registration friction and no sensitive personal identifiers stored just to use the service. If you uninstall the app, your local keys are gone and your identity effectively disappears.

The interface focuses on being minimal and intuitive: paste or type your contact’s user ID, open a chat, create or use the password you received from your contact and start talking. There are no public profiles, no contact syncing, and no social feed—just private messaging secured with next‑generation, Quantum resistant cryptography for users who care deeply about privacy and long‑term confidentiality.
