No. GoCarma never shares your personal data with anyone.
The only data that GoCarma may share externally is whether or not a vehicle you registered is verified with HOV status. This is shared in places like Dallas-Fort Worth in response to a toll transaction being processed by a toll operator.
Anonymized travel data is shared in aggregate form with government partners, to help with things like traffic forecasting and travel pattern analysis, but none of this includes personally identifiable information.
