In the past, I’ve heard about how Google can keep records of all your Google phone’s past locations and text messages.
What about RCS messages which supposedly are encrypted from Android to Android? I know that it’s possible that they secretly keep a log behind the scenes, but as far as the regular consumer knows is there any record being kept with regard to the contents of these RCS messages?
If you’re able to successfully navigate the fucking maze of settings both on your device and your account, and stay up to date when Google silently opts you into new “features” so you can opt out of them, then probably not. But honestly, no one knows except Google, and they’ve given you every reason not to trust them.
In regards to RCS, probably the same as every other quasi-private messaging platform: the content of your messages is encrypted and private, but your social graph, who you talk to, when, and how often, is property of the corporation. Or if you’re messaging someone on a Samsung or Apple device, then multiple corporations.
