PATENT-PENDING ARCHITECTURE

FL77 Spatial Telemetry Core

ChatBlu’s radio layer treats every handset as a sovereign node. Identity rotates. Range is physical. Relays are bounded. Nothing leaves the airwaves for a remote server.

FL77 Spatial Telemetry Core Radio Handshaking

Nearby devices exchange short-lived radio signatures inside a ~50-meter spherical field. ChatBlu rotates advertising tokens on a rolling cadence so static identifiers never linger on the air — reducing the risk of passive location footprints while confirming proximity for intentional pairing.

  1. 01 Beacon — Node broadcasts a salted FL77 signature over BLE airwaves.
  2. 02 Sense — Peer measures signal strength to estimate spatial distance.
  3. 03 Handshake — Intentional QR / token verify white-lists the peer for private threads.
ROLLING IDENTITY 30s CYCLE

FL77_GHOST · TOKEN_SCRAMBLE · LOCAL_ONLY

Asynchronous 4-Hop Tunnel Bridge

When a direct line-of-sight link is unavailable, ChatBlu can forward encrypted message packets through intermediate peers. Each relay increments a hop counter. At hop four, the packet is dropped — a hard ceiling that protects battery life and bounds how far traffic can travel through the local mesh.

USER JOURNEY

CHATBLU IN ACTION: HOW IT WORKS FOR YOU

01

STEP 1: CHOOSE YOUR HORIZON

Open ChatBlu and instantly set your status. No accounts, phone numbers, or emails are ever requested. You are identified purely by a localized, rotating cryptographic token signature.

02

STEP 2: OFF-GRID PAIRING

Flash your secure, rolling in-app QR code to a colleague or classmate nearby. Once your physical phone antennas acknowledge the handshake inside a 50-meter radius, a permanent, private offline chat thread is locked onto both devices.

03

STEP 3: GUARANTEED DELIVERY

Tap send. ChatBlu checks your device. If you are outdoors or on-grid, your premium Intelli-Route failover can securely bridge data over traditional networks. If you are deep inside a dead zone or tunnel, your message fragments safely hop peer-to-peer across willing background app beacons until they find their destination.

PREMIUM CAPABILITIES

Pro-Tier Delivery Power

Two explicit upgrades that extend reach when free-tier radio limits or dead zones would otherwise stop a message cold.

PRO SUBSCRIPTION

Unlimited Mesh Mileage

Our free tier enforces a strict 4-hop limit to safeguard local battery thresholds on every participating handset. Unlocking a Pro subscription completely shatters that ceiling — granting unlimited peer-to-peer Bluetooth hops across any active, willing device beacons running ChatBlu in the background. Messages keep traveling through the local mesh until they reach their destination, without the freemium hop wall standing in the way.

FREE CEILING 4 HOPS
PRO CEILING UNLIMITED
DEAD-ZONE EXTINGUISHER

Intelli-Route Extended Delivery

When local radio frequencies signal a drop, ChatBlu’s hybrid failover net intelligently and automatically cascades across cellular data towers, Wi-Fi clouds, and local BLE antennas to locate the nearest online Mesh Border Beacon standing at the boundary of a dead zone. That beacon pulls the data chunk out of the cloud path and whispers it straight through the airwaves into the offline grid — guaranteeing delivery anywhere the mesh still has a foothold.

  1. 1 Local BLE mesh attempts delivery first.
  2. 2 On radio drop, cascade to cell / Wi-Fi border beacons.
  3. 3 Beacon re-enters the offline grid and completes the hop.

Privacy Policy

ChatBlu Messenger is engineered for absolute data minimization. The FL77 peer-to-peer radio architecture means Broad-I LLC does not operate message servers, analytics pipelines, or cloud retention stores for ChatBlu traffic.

  • Zero collection: We do not track, scrape, parse, or hold user names, message payloads, contact graphs, or physical location logs on Broad-I infrastructure.
  • On-device isolation: Communication history and pairing state remain on the user’s device storage and local radio path unless the user deletes them.
  • No middlemen SDKs: ChatBlu’s design goal excludes third-party advertising or behavioral analytics frameworks that would invent a remote data footprint.
  • No central repository: Broad-I LLC maintains zero central database repositories for ChatBlu message content or mesh telemetry.

Terms of Use (EULA)

By downloading, installing, or activating ChatBlu Messenger, you enter into a binding agreement with Broad-I LLC. You acknowledge that the application operates locally through device airwave frequencies and peer relays, and is provided strictly “as-is.”

  • Provider role only: Broad-I LLC is an application software provider. It does not own, manage, lease, or operate server networks, cloud storage arrays, or transmission lines for ChatBlu traffic.
  • User accountability: Users assume full personal responsibility for complying with applicable laws, safety rules, and regional regulations when using off-grid communications.
  • No retrieval capacity: Because there are no registration servers or cloud logging loops, Broad-I LLC cannot retrieve deleted local records, monitor regional air chats, or produce message content that never existed on its systems.
  • Acceptance: Continued use constitutes acceptance of these Terms and the full EULA published at chatblumessenger.com.
