Wingit respects your privacy and neither collects any of your data nor tracks its users.
At least for now Wingit is a consume-only App, as such there's very little personal or personally identifiable data to begin with. There are no logins, no tracking cookies, and your location data is used only on your device. The only time Wingit transmits and stores any data on a need-to-know basis is when you're explicitly using the built-in feedback functionality. Specifically, this means some device metadata, such as screen resolution and model, however does not include any location or otherwise sensitive information.
