MiitWell is different when it comes to privacy.
Other services will do the matching of you and a prospect by sending your location out to “the internet”, typically using information from sites like Facebook. This exposes you to accidental or intentional usage of location information and other identifying bits in ways that you don’t expect or desire.
MiitWell does all the identification and matching effort locally on your device. If you broadcast one or more profiles, that information stays in the room you’re in. When you set up profiles, the profiles are stored on-device (and wherever you back up your device, of course).
Profiles do not automatically broadcast – you pick and choose which ones are appropriate for the event you’re attending and broadcast (or stop broadcasting) with a tap on the profile in question.
