Trackers?  None that I know (jeez, is it tinfoil hat day or what?).  But here's a list of permissions:

I was wondering if by ‘tracker’, the intent was something like last.fm’s scrobble process, but the OP’s post was unclear to me, and I don’t use anything like that…

I think I misread the OP’s post completely, as I searched and came up with this… ha

If you subscribe to any music services, each has it’s own privacy statement.

Sonos also has their own Privacy statement, located here. 

 Many thanks for your response, to perhaps clarify my question duck duckgo offered a tracker which I installed and the screed of info collected by Functional Data, the company, seemed at first reading excessive but now having read the link provided by your goodself which is beneficial, thank you for that.

I love my Sonos and with14.18 even more so.
