Yes sir, turn the darn thing off. We do here in our household. We have a landline so the cellphones are always off except when we're out on the road and somebody needs to call us. We don't feel the urge to go back in the house when we forget it in our metal box.
I don't trust Alexa. I wrote about Amazon Rekognition being sold to police forces in Florida and Oregon. It's just going to get worse. I don't have that thing snooping on me. Like you, I have enough brains and fingers to DuckDuckGo it.
Location tracking is off on my phone, I have addons for my browser (Opera has built in VPN, Firefox I use Blur or uBlockOrigin for tracker blocking).
Oh and we tried the do not call list and we still get telemarketers. So, we don't answer any phone call that we don't know and expect. The answering machine is gone too :)
