We use location in-app to provide transit navigation services. Your location stays on your device unless you plan a route from it, when it’s sent as the route’s starting point, or you share a live ride. We may keep a log of users’ routing requests to make sure our services are running as intended. Stored data is anonymous: it’s not attached to your name, email, etc. There are no accounts in Modemix, and we don’t ask for your name or email.
Your ride is only shared if you tap Share ETA. While you share, the app sends your precise location and estimated arrival to our servers about every 10 seconds, along with your route and destination. Anyone with your link can see this without signing in, so only send it to people you trust.
When your ride ends, your last location stays visible for one hour. Tapping Stop Sharing removes it right away. We may store your route for up to 24 hours after you started sharing, and then it’s deleted from our servers.
Shared rides carry an anonymous ID, the same for every ride you share, so people who follow your rides can recognize you. Any name they give you stays on their device.
Your trip data is used solely to provide navigation services, and we don’t send it to advertisers.
Most navigation requests are handled in-house on our cloud servers. We also use third-party providers for maps and analytics, and they receive the information needed to provide those services.
The web version of Modemix may show ads from Google AdSense. At this time, the iOS and Android apps don’t have any ads. Third party vendors, including Google, use cookies to serve ads based on a user’s prior visits to this website or other websites. Google’s use of advertising cookies enables it and its partners to serve ads to users based on their visit to this site and/or other sites on the Internet. You may opt out of personalized advertising by visiting Ads Settings or aboutads.info.
You may opt out of location services through your device settings.
