My Vote — com.mccwho.myvote
Summary
My Vote is an HTML5/PWA webapp: it runs in the browser and does not collect, transmit or share any personal data to servers operated by MCC. Multi-device mode uses WebRTC peer-to-peer between participants' browsers: votes, session names and voting options stay on the connected devices and never transit through our servers. Initial pairing (signaling) uses the public PeerJS service, which only sees ephemeral Peer IDs — never session contents. The webapp does not display ads, does not use analytics services, and does not integrate third-party SDKs.
Data stored locally on your device
The app stores in the local database (Room SQLite) and local preferences (DataStore):
- Names and/or labels of voting sessions you create as host
- Voting options entered (e.g. "Yes / No", "Pizza / Sushi / Burger")
- Votes recorded during the session (in memory, while the session stays open)
- Local history of recent sessions (in `localStorage`)
- Reusable setup templates
- Client-side recent sessions (peerId, alias, color — max 5)
- Your preferences (theme, palette, range, custom STUN/TURN)
- Offline cache managed by the service worker (static webapp assets)
All this data stays in the app's private storage on your device. Uninstalling the app deletes it.
Multi-device mode (local LAN)
The app supports a host/client mode that works exclusively on the local Wi-Fi network you are connected to. The host phone opens a small WebSocket server (Ktor) accessible only via the local IP; clients connect via QR or IP+PIN. Data flows only between devices on the same local Wi-Fi network and never passes through third-party servers. When the session ends, all connections are terminated. The app does not use the Internet for inter-device communication: the connection is strictly peer-to-peer.
Permissions requested and why
| Permission | Why |
|---|---|
Camera (getUserMedia) | Scan the QR code to join a voting session (client mode). The browser asks for explicit consent on first use. The video stream stays on-page and is never sent to any server. |
Wake Lock API | Keep the host phone's screen awake during the lobby and voting session, so the P2P connection isn't torn down when the screen would otherwise turn off (replaces the old Android app's ForegroundService). |
localStorage | Store session history, templates, preferences and recent sessions (client-side). Data stays in your browser and is never synced to any server. |
WebRTC + PeerJS signaling | Establish the peer-to-peer connection between participants' browsers. Signaling (SDP exchange) uses the public PeerJS service — it only sees ephemeral Peer IDs, never session contents. Once connected, data flows directly between browsers. |
Service Worker | Offline cache of the webapp's static assets (HTML/CSS/JS/icons) to allow functioning without a connection after the first load. |
All permissions are used exclusively for the features described. No permission is used in the background or for other purposes.
