Please don't use words like "hoover" in relation to data, it makes no sense.
This reasoning goes against the Right to Delegate [1]. It doesn't matter if you're remembering it using your brain, a notebook, an assistive tool, or Screenpipe. You're just remembering it.
Whether or not you would tell another person these details is another matter altogether, and has no relation to Screenpipe, which does not, from my knowledge, republish your information anywhere else automatically.
In summary: we're talking about an auto-remembering tool here. Your example talks about repeating certain sensitive details. There is no relation between your example and the topic on hand.
"But isn't it the same? You're repeating the information to Screenpipe!"
In the context of your example, I consider "repeating" to be "repeating to a person". See:
> A well-meaning friend or coworker might never consider telling another person these personal details, but not think twice about it when enabling a service like this.
"Another person". Just as you would not think twice about repeating such data to a notebook (e.g. maybe you have bad memory), you also would not think twice about repeating such data to Screenpipe.
There are some exceptions, such as confidential information, where you would not be allowed to write things down on a notebook. In those cases, yes, you should not use Screenpipe. But the IBS example does not cover that; a friend, in my experience, generally does not expect such levels of secrecy unless they explicitly request so (e.g. "Hey, turn off your computer for a while/Hey, don't bring any phones to my house. We need to talk.").
"What about phone recording laws?"
Yeah, you're right. That throws a wrench in my argument that automated remembering has no difference to manual remembering. I could say that there ought to be no difference, but you're right that this isn't necessarily the case.
I could then argue that this only applies to phone calls, and perhaps video calls. For example, there's no need to get the consent of the people around you in public when you record or take photos, as long as you're not harassing someone.
But then this just becomes a legal question (what is) rather than a moral one (what ought to be).
