The Bridgefy app works thanks to the Bridgefy SDKwhich is basically software that makes any mobile app work without the Internet.

This means that it connects devices 100% without Internet, and can cover large distances.

The Bridgefy messaging app is currently undergoing a series of security and privacy improvements. Sometime during October 2020, we will publish a version of the Bridgefy app that will be extremely safe and private. For the time being and until further notice, we urge users to be cautious when using the Bridgefy app, as outside actors may interfere with it in unfavorable ways for users.

Android users will see a prompt pop up when they’re first using the Bridgefy app, which asks for access to location permissions. This does not mean that we’re going to be tracking or using your location, it just means that the Android operating system requires it from us app developers that need to use the Bluetooth antenna on your phone.

Yes! Bridgefy works on any iOS device that runs at least iOS 10, and has the latest version of the Bridgefy app. iPhones, iPads, iPads Mini, and iPads Pro can all text each other without Internet using the Bridgefy app!
