I’ve got to ask you something here and it’ll probably sound weird, but here in the UK if you did that you’d probably be in for a hard time, legally standing recording others without informing them.

Not weird at all! I did my homework before implementing it. I’m in a single-party consent state (Utah), and so is my ex-wife (Idaho). No consent required as long as one party (I.e. me) is informed.

But I’m more curious how often you listen back to these phone calls since you say you record each one, and do you keep lots of them/off-site etc?

They’re recorded in .opus format, so a 5 minute call, for example, is barely 500 kilobytes. And yes I have reviewed many of them, especially during my divorce some years back. They are stored on my phone which 1) syncs to my NAS via Syncthing and 2) uploads to Google Drive tied to a Workspace account that I pay for.

I don’t hide the fact that I record my calls, everyone who knows me knows this fact, including my wife (I am happily remarried). I also back up my texts, going back almost a decade now, which came in handy during the divorce.
