Just to counter balance the discussion, no.
Yep, lots of shops, cafes have a small camera in the corner, but most are.either broken or only live - ie no recording. And they accept cash... in fact lots of takeaways only take cash.
There's ANPR on major roads, but not on minor ones. (I recall there is / was? an app for tracking where ANPR cameras are located on OSM maps)

I was also told recently thelat even the mobile speed detector vans publish - rougly - where they'll be on Facebook, so it's not all bad.
But, digital surveillance (think of the kids / terrorists) is definitely eroding privacy and affecting the general public to move in the wrong direction.

I also use it to sync a calendar for Home Assistant too
And it effectively backs up my Contacts too.
