Prohibits providers of commercial mobile service and developers of mobile application from disclosing customer's global position system data to third parties under certain circumstances.

S 2140 prohibits mobile service providers (like phone companies) and app developers from sharing customers' location data with third parties without explicit consent. It requires developers to get customers' affirmative agreement - via a clear "I agree" prompt - before sharing location data, and bans third parties from selling this data or sharing it beyond the purpose for which consent was given. Exceptions apply for legal requirements like court orders or law enforcement requests. Violations would be treated as consumer fraud, potentially resulting in fines up to $20,000 per offense. The bill directly affects app developers, mobile providers, and third-party data users operating in New Jersey.
