Recommendations about which Android texting app to use?

Could someone please recommend a text messaging app for Android that is reasonably secure?

Verizon is discontinuing their native texting (SMS) app. They recommend switching to Google Messages, but I would not like Google to have access to my entire text messaging history. I tried Signal, but my old messages don't transfer over (minor problem), and almost none of my family are willing to switch to Signal (big problem). When I search for advice, I get a bunch of AI slop articles and advertisements. So I figured I might have better luck asking here: Is there any text messaging app for Android that works well and isn't going to hoover up all my data?
