Apart from the fact that in the security settings there is the option to turn off any data being sent to Honda and any advertising or marketing by them, it is a useful app to have for the security features and info it gives the owner/driver.
I would check that very carefully if I were you. I think you're referring to the app settings (?): it is probably possible to control what the app is doing by means of it's settings, but that doesn't necessarily control what the dongle is doing. The Ts&Cs suggest the only way to stop the dongle transmitting your data is to physically remove it:
From the
Licence Agreement:
"9.5 In the event that a Dongle has been installed into your Honda vehicle and you wish to
cancel your Subscription before the end of the Fixed Term you should return your Honda
vehicle to an authorised Honda dealership to disconnect the Dongle, otherwise some of your
personal data may continue to be received by Honda, Bright Box and affiliated third parties
as set out in the Privacy Policy for as long as the Dongle is connected to your Honda vehicle.
It is your responsibility to ensure that the Dongle is disconnected on the cancellation of
your Subscription, however it has arisen."
From the
Privacy Policy:
"2.4 Please be aware that while a Dongle is connected to your vehicle, we may continue to
process some of your personal data for the purposes described above, including when your
Subscription has expired. Therefore, if you no longer wish for Honda to process such
Personal Data, please arrange to have the Dongle disconnected or deactivated by
your local Honda dealer or supplier."
Now why would they say that if you could just switch it off from the app ?
However, whether you are prepared to pay the price (ie loss of privacy) in order to gain the functionality is clearly a personal decision.
