No. Once you’ve signed in, it’s impossible to stop Smartphone apps from collecting your data,  You can, however,  limit what they get by: 1. Using a throwaway email and a “burner phone” not linked to any other accounts. 2. Never offering more information than absolutely necessary.  3. Opt out from data collection in the privacy and security settings. 4. Checking the app’s Privacy Policy to get an idea of who they might be working with. Finally, use Private Internet Access. While a VPN can’t prevent apps from tracking you once you log into their service, they do encrypt your traffic between apps and on other services. This goes a long way to shield you from tracking and surveillance.
