Legal Notice & Terms of Use

Last updated: September 2026 · Application convoice.app

1. Service operator

Convoice is an independent service operated by an individual. It is not associated with any company, brand, or automotive manufacturer. Tesla® is a registered trademark of Tesla, Inc. Convoice is neither affiliated with nor endorsed by Tesla, Inc.

2. Nature of the service

Convoice is a real-time web application that allows electric-vehicle drivers to share their GPS location, exchange text messages, and communicate by voice in ephemeral channels — similar to CB radio.

The service is provided free of charge, with no sign-up and no user account required.

3. Data collected and processed

Convoice collects no personally identifiable information. Here is what is processed:

• GPS position — transmitted in real time to other channel members only. Not stored on the server. Disappears on disconnect.
• Text messages — relayed live to channel members. Not stored on the server. Ephemeral.
• Voice (WebRTC) — peer-to-peer connection wherever possible. The server only relays signalling (SDP/ICE) and never records audio.
• Connection metadata — chosen handle, channel code, connection timestamp and session duration — retained for up to 12 hours for maintenance purposes, then automatically deleted.
• Pinned messages (public channels only: CB and Superchargers) — short text notes (max 250 characters) that a user voluntarily makes visible to other channel members: charger status, useful tip, meeting point. Stored on the server for up to 48 hours and then automatically deleted. Maximum 5 concurrent pinned messages per channel (FIFO). No IP address is stored: anti-abuse uses a daily-rotating identifier that cannot be linked back to the user. Private channels (codes shared between friends) do not allow pinned messages — their content stays 100 % ephemeral.

Location privacy: in public channels (EV BAND and Superchargers) the server automatically applies a random offset to broadcast positions — roughly 200 m while driving (above 15 km/h) and 750 m at rest, with the offset's angle and distance re-drawn every minute so that averaging several samples cannot recover the true position. This decision is made server-side: your exact position never leaves the server on a public channel, including in the snapshot sent to someone joining the channel.

Two exceptions, by design:

• At the charger: within 300 m of the channel's Supercharger the position is broadcast exactly — privacy adds nothing once everyone is parked in the same place, and the precise marker is genuinely useful for finding each other among the stalls.
• Private channels: positions are broadcast exactly, with no offset. That is the point of a private channel — its members have chosen to share their real position. Only join one with people you are willing to share it with.

4. Cookies and local storage

The application uses only your browser's local storage (localStorage) to remember your handle and recent channels, exclusively on your device. No cookies are set. No trackers. No advertising networks.

5. Data sharing

No data is sold or monetised, and no advertising tracker is used. Six third-party services take part in running the application:

• OpenStreetMap / Overpass API — loading the Supercharger list. Requested by the server, once a week, with no user data at all.
• OpenStreetMap (tiles) — the map background. Your browser downloads the tiles it needs directly, which tells those services your IP address and the area you are looking at, as on any site that displays a map.
• Nominatim (OpenStreetMap) — searching for a destination by name. Requested by your browser, only when you type a search, and carrying the text you typed.
• Google Fonts (fonts.googleapis.com, fonts.gstatic.com) — the interface typefaces. Downloaded by your browser when the page loads, which discloses your IP address to Google. No Convoix usage data is sent.
• unpkg.com — the Leaflet mapping library (CSS and JavaScript). Same principle: your browser fetches the files, which exposes your IP address to that CDN.
• OpenRouteService — road-route and estimated-arrival calculation, only in a private channel where a destination has been set. The server then sends that service the origin and destination coordinates of the trip concerned. No handle, no identifier and no message content is sent, and no request is ever made for public channels. If the feature is not configured on the server it is simply disabled and no data leaves.

6. Hosting

The application is hosted on a private virtual server (VPS) in Europe. Standard server-side system logs (IP addresses, HTTP requests) may be temporarily retained by the hosting provider in accordance with their own policies.

7. Security and channels

No channel is password-protected. Whether it is public (CB), tied to a Supercharger, or "private" (a custom code shared between friends), it is technically accessible to anyone who knows its name. The channel code acts as an identifier, not a secret. Never share sensitive information (personal, financial, medical) through this application, and only disclose the name of a private channel to the people you want to be in it.

Communications are not end-to-end encrypted. The server relays messages in clear text between participants in the same channel.

8. Pinned-message moderation & reporting

Pinned messages are user-generated content temporarily hosted by the service. Every pinned message can be reported directly from the application via the 🚩 button shown next to it — a message receiving 3 distinct reports is automatically hidden.

For takedown requests, in particular regarding illegal, defamatory or rights-infringing content: contact@convoice.app. Removal is processed within 24 business hours of receiving the notice.

9. Liability

The service is provided "as is", without guarantee of availability or continuity. The operator shall not be held liable for any use made of it, in particular while driving. Never use your phone while driving. Convoice is designed for Tesla mode (in-car display) — mobile use outside the vehicle remains the user's sole responsibility.

10. Intellectual property

The Convoice source code is published under the MIT licence. Logos, visuals, and graphic assets remain the property of their respective authors. Interface icons and flags use the Twemoji set, licensed under CC-BY 4.0.
