AdHoc DM

AdHoc DM is a secure, privacy-first messaging application designed to give you
total control over your digital conversations. By combining advanced
End-to-End Encryption (E2EE) with an ephemeral relay system, AdHoc DM ensures
that your messages stay private, decentralized, and leave no trace on any
server.

- WHY CHOOSE ADHOC DM?
In an age of constant data harvesting, AdHoc DM is built on the principle that
your private conversations should remain just that—private. We don’t just
promise security; we enforce it through architecture.

1. True End-to-End Encryption (E2EE)
Every message, photo, and interaction is encrypted locally on your device
before it ever hits the network. Using the X25519 Diffie-Hellman protocol for
key exchange and 256-bit AES-GCM for content, only you and your recipient can
read what is sent.

2. The Ephemeral Relay - Zero Server Footprint
Unlike traditional "secure" messengers that store your encrypted history on
their servers indefinitely, AdHoc DM uses an ephemeral relay. Messages are
held in a secure, temporary state only until the recipient downloads them.
Once delivered, they are instantly and permanently deleted from the relay. No
logs, no cloud backups, no digital breadcrumbs.

3. Total Anonymity
No phone numbers. No email addresses. No linking to your social media. AdHoc
DM uses anonymous peer-to-peer identifiers, allowing you to communicate
without revealing your personal identity to the platform or third parties.

4. Secure Media Sharing
Send high-fidelity images with confidence. Every photo is encrypted with the
same rigorous standards as your text messages and is subject to the same
"pull-and-delete" cleanup system, ensuring your media doesn't live on a server
forever.

- KEY FEATURES
* Instant QR Pairing: Establish a secure, encrypted channel in seconds by
simply scanning a friend’s QR code.
* Local-Only Storage: Your chat history is stored securely on your device
using sqflite. We never upload your history to the cloud.
* Background Sync: Receive notifications and fetch messages even when the app
isn't active, so you never miss a beat.
* High-Fidelity Media Viewer: Enjoy a premium viewing experience with
full-screen support, pinch-to-zoom, and panning for received images.
* Modern, Clean Interface: A fast, responsive UI built with Flutter, designed
for ease of use without compromising security.
* Delete messages or entire DMs on both ends.

- UNDER THE HOOD (FOR THE SECURITY CONSCIOUS)
AdHoc DM uses industry-standard cryptographic primitives to ensure your data
is safe:
* Key Exchange: X25519 (Elliptic Curve Diffie-Hellman).
* Encryption: 256-bit AES-GCM.
* Key Derivation: HKDF (Hash-based Key Derivation Function) to ensure every
single message has a unique, non-reusable key.
* Architecture: Feature-First Layered Architecture for maximum reliability
and code integrity.

- YOUR PRIVACY, OUR MISSION
AdHoc DM is perfect for:
* Confidential Business: Discussing sensitive projects or internal
strategies.
* Journalists & Activists: Communicating with sources securely.
* Personal Privacy: Keeping your private life away from big tech data mines.
* Minimalists: Those who want a messaging tool that does its job and leaves
no mess behind.
