The data included in OpenSignal insights is aggregated both geographically and temporally at a resolution that makes it impossible to identify any individual user. All we show are averaged stats over a monthly or quarterly period for a given area.
Part of our project is to inform users about how carriers are performing, but also to inform carriers how they're performing so that they can improve their service for their users. We use our data to independently regulate the carrier market, from both the supply and demand sides as we think this is the best way to help effect much-needed improvement. We sell to operators so that we don't have to charge consumers or show them annoying in-app ads!
