No Towers. No Pings. No Records.
DeaDrop uses Bluetooth as a transport layer between two devices in physical proximity. No cellular towers. No WiFi routers. No internet connection. No carrier metadata. Every message is encrypted client-side before it touches the radio.
No cellular network involved. No carrier metadata. No tower triangulation. Pure Bluetooth radio between two devices. Nothing to subpoena because nothing was transmitted through infrastructure.
Messages encrypted before they leave your device. Even intercepted over Bluetooth radio, they are ciphertext. Pre-shared key pairing. Web Crypto API -- no external libraries, no dependencies.
Every message hashed. Receiver confirms the message was not tampered in transit. Chain of custody on every exchange. Hash verified automatically on receipt.
Optional auto-destruct. Message deletes after opening, or after configurable timer -- 30 seconds, 1 minute, 5 minutes, 15 minutes. No trace on either device. Memory only.
Write in your language, they read in theirs. French and English seamless. Translation happens locally, never on a server. Built-in operational phrase dictionary. Full privacy preserved.
Bluetooth range 30-100 metres. Building-to-building, room-to-room, park-to-park. No infrastructure needed. No access points. No routers. Two devices and proximity.
Five steps. Two devices. Zero infrastructure. The protocol handles pairing, encryption, transfer, decryption, and optional destruction.
| Step | Action | Detail |
|---|---|---|
| 1 | Pair | Two devices pair via Bluetooth in physical proximity. Pre-shared encryption key exchanged once, verified by fingerprint. |
| 2 | Write | Compose message. Select language. Message encrypted with AES-256-GCM client-side using Web Crypto API. |
| 3 | Send | Encrypted payload transferred via Bluetooth GATT characteristic. No network, no towers, no pings. SHA-256 hash appended. |
| 4 | Receive | Other device receives, decrypts, verifies SHA-256 integrity hash, auto-translates if languages differ. All local. |
| 5 | Burn | If read-and-burn enabled, message self-destructs after viewing or timer expiry. Removed from memory. No disk. No cache. |
Two devices in proximity. One shared key. No servers. No records. Messages exist only in memory, only on the paired devices, only until they are read.
Both devices open DeaDrop. One scans, one advertises. Bluetooth handshake. Pre-shared encryption key entered on both sides. Fingerprint verified visually.
Compose your message in any language. AES-256-GCM encrypts it client-side before it touches the Bluetooth radio. SHA-256 hash generated for integrity verification.
Encrypted payload sent over Bluetooth. Receiver decrypts, verifies hash, auto-translates if needed. If read-and-burn is set, the countdown begins on open.
Functional Bluetooth encrypted messaging. Connect a device, set your key, compose and send. Everything runs in your browser. Nothing stored. Nothing transmitted over the network.
