From Apple's site: "By enabling Location Services for your devices, you agree and consent to the transmission, collection, maintenance, processing, and use of your location data and location search queries by Apple and its partners and licensees to
provide and improve location-based and road traffic-based products and services."
You might want to look up the meaning of the words partners and licensees.
"Location-Based Suggestions: The location of your iPhone will be sent to Apple to provide more relevant recommendations. If you turn off Location Services for location-based suggestions, your precise location will not be sent to Apple."
So...not sending your precise location. But sending something not precise. To Apple.
