Can I give or loan my BodiMetrics Performance Monitor to someone else?

Sure. They will need to set up a new profile on the BodiMetrics Performance Monitor. Note that if they choose to sync the BodiMetrics Performance Monitor with their own smartphone, they will receive a copy of your data unless you have already deleted it. So, depending on how comfortable you are in having that person having access to a copy of that data, you may want to delete your profile and data if you intend to hand it to a stranger.
