Proximity voice chat for League of Legends. Hear nearby players (allies and enemies) with volume that scales by in-game distance — enemy voices fade in around champion-vision range and grow louder as they close.

Standalone Windows desktop app built with Tauri 2 + WebView2. No Overwolf, no third-party voice service, no telemetry. Registered + approved on the Riot Developer Portal (App ID 809090).

Download the latest lolproxchat.exe from Releases. Single portable executable — no installer.

Requirements:

• Windows 10 1809+ or Windows 11
• WebView2 Runtime (ships with Windows 11; pushed via Edge on Windows 10)
• League of Legends in Borderless mode (Settings → Video → Window Mode → Borderless). Required — DX9 true fullscreen takes exclusive GPU output and no transparent overlay can render over it.

Launch the exe before or during a League match. The panel auto-attaches beside the minimap once a game is detected.

Windows will show one of these on first launch (the exe isn't code-signed; this is the standard treatment for any unsigned binary downloaded from the internet):

• "Windows protected your PC" (SmartScreen) → More info → Run anyway.
• "This app has been blocked for your protection" (Mark of the Web) → right-click lolproxchat.exe → Properties → check Unblock → OK → re-launch.

Subsequent launches don't prompt.

Every release body includes a SHA-256 hash. Compare it against your downloaded exe to confirm you got the official build (defends against in-transit tampering, mirror reposts, typosquatted re-uploads):

# PowerShell
Get-FileHash lolproxchat.exe

# WSL / git-bash
sha256sum lolproxchat.exe

Every release exe is also submitted to VirusTotal during the build, and the scan link is included in the release notes — verifiable against 70+ antivirus engines before you download.

1. Make sure LoL is in Borderless mode.
2. Launch lolproxchat.exe. The panel appears in the middle of the screen showing the current lifecycle ("Waiting for League of Legends", "In champion select", etc.).
3. Once you load into a match, the panel jumps to the left edge of the minimap. Other players running LoLProxChat in the same match appear within a few seconds.
4. Always Open mic is the default — just talk. MIC = self-mute, VOL = mute everyone, MUTE per row = silence a specific player.

For the rest — every Settings toggle, troubleshooting, log-grab flow, uninstall — see the user guide.

1. Game detection — reads the LCU and Live Client Data APIs for game phase + player roster. No memory reads, no injection.
2. Position — the app captures the minimap image, finds champion icons on it by color and shape, and identifies which champion each one is with a trained image-recognition model — producing your position in in-game coordinates.
3. Signaling — players in the same match join a deterministic WebSocket room (room ID = hash of sorted player names) on a self-hosted Node server.
4. Voice — WebRTC peer-to-peer audio between players (Opus 128 kbps, DTLS-SRTP). No audio touches any server.
5. Proximity volume — each client streams its XY coordinates to the signaling server (over the same WebSocket used for presence/signaling); the server computes pairwise volumes for everyone in the room. Team voice is always full volume (no proximity); cross-team (enemy) voice fades in at ~champion vision range (~1350 game units) and grows louder as they close. Server-enforced — a modified client cannot bypass the team filter or range cutoff. Clients only ever receive { peerName: volume }, never another peer's raw position.

For depth, see docs/architecture.md.

LoLProxChat collects no analytics, no telemetry, no fingerprinting, no persistent user identifiers. The only data that leaves your machine is your summoner name (for room routing — same name visible on the match scoreboard), your XY position (sent to the server over TLS, held in process memory only for as long as you're in the room, never logged), WebRTC signaling, and the voice audio itself (DTLS-SRTP, peer-to-peer, never touches the server). Want to keep your public IP private even from peers in your match? Settings → Hide IP (Force TURN) routes voice through the TURN relay. See docs/threat-model.md for the full breakdown.
