What EV·ENGINE knows about you
Your location never leaves the browser. EV·ENGINE reads your position, turns consecutive positions into a speed, and discards the position. Coordinates are never transmitted and never stored. There are no cookies, no third-party trackers, and no identifier that outlives the browser tab.
Location
The browser reads your position, the app turns consecutive positions into a speed, and the position is discarded. Coordinates are never transmitted and never written to disk. Speed is a single number and carries none of the information a coordinate does.
Analytics
The app counts things: which machines get chosen, what audio latency the browser reports, how often a browser falls back from the AudioWorklet. Those counts are how the sound gets tuned against real cars instead of against a laptop on a desk. You can see the same figures on the stats page.
Collection is first-party. Events go to /api/e on ev-engine.com and nowhere else, so the page keeps the property it had before analytics existed: it loads nothing from any other domain.
- No cookies.
- No advertising and no third-party trackers.
- No identifier that outlives the tab. The session id is generated on page load and thrown away when the tab closes, so two visits cannot be linked to each other or to you.
- No GPS coordinates, in any form.
One field comes from the network rather than from the page. Cloudflare reports the country a request arrived from, which is how the stats page shows a country breakdown. It is a country, recorded per request, attached to no identifier.
What stays on your device
The app remembers which machine you picked, in localStorage under evengine_car. It never leaves the browser, and clearing site data clears it.
Switching analytics off
Run localStorage.evengine_no_analytics = '1' in the browser console. It sticks on that device until you clear site data. Turning on Do Not Track has the same effect.
