Does Car Cam collect diagnostic data from OBD port?

I am very hesitant to plug a Ring device into my OBD port that then has cellular connectivity. Insurance companies have devices which collect a ton of data from your vehicle. First, there are disclosures about the data they collect and they do not collect this data in real time. Can someone from Ring confirm that data is NOT harvested from my vehicle? The only data I expect the device to use is related to battery/power. Is there an alternate way to power the device? Sorry....I have HUGE trust issues with Ring/Amazon. Just seems like I am paying for a device and monthly service that then gives them all the data from my vehicle. Additionally, it appears to open two additional risks - the ability for data to be written deliberately to my ECU as well as the potential for the the connection to be hacked and exploited. There are a ton of articles that recommend to never connect a 3rd party device to your OBD-II port. The same articles state you should NEVER attach a device that has network connectivity. I'm just wanting to hear from Ring on this topic. What assurances are provided? With so many professionals stating you should never do this, why does Ring do this?
