There are many settings that should be turned off on an IPhone or Galaxy. The only app that's downloaded on my older IPhone is the BibleApp, I know it's secure.

Getting rid of G@@GLE on all your devices....a Must! Wife & I did it years ago.
No GeeMail accounts, period! DuckDuckGo, the only search engine to use.

No regular driver vehicles with tracking devices factory installed, am sure that will be difficult for numerous on this site.

Get off F&cebook. Contact your friends & followers with your contact info, then delete your acct.
Beyond amusing how naive some regular posters are on this site in respect to FB. FB's only purpose is to harvest info from you, your friends, family, & business contacts, & build a profile of you which can be spun anyway which way FB desires. Last, of course, sell that profile to whoever. FB owns other platforms, like Instagr@m, know what they are, don't use them.

Install a good VPN, & be careful what you post on the Net.
