I avoid using a specific app if I can access their website.i also avoid the App if you can't access the same info via a browser. Why have a 'BBC' App, when their website gives me the same information? I also use private browsing in Safari and a VPN.
No, I'm not paranoid, but that doesn't mean they are not out to track me (for their own financial benefit)!
Perhaps if they paid me CHF1,000 (none of that funny money for me) a month I would be happy to have them track me. But they wouldn't do that, would they.
