Accuracy is actually unknown, and
unknowable unless the user actually goes through with the relationship, and even then, its accuracy applies only to that particular relationship, and not to the simulation method as a whole, unless a systematic review of relationships that started with the app can be done . And it's actually quite wrong to say that "reliability drops only if he doesn't share enough personal data" because a particular result comes from the data that's already been provided. In order for your statement to be true, first a simulation has to run with a set of data, and then another one run immediately afterward with some of the data removed. And that's obviously not what's happening here. The manga had that line for a reason and I translated it as faithfully as I could, that your trust/confidence/sense of reliability of the result will be higher more data you provide. Does it make it more
accurate? No, because that's an objective valuation that we cannot know as I stated already. So there's nothing fantastical or sci-fi about the app. The tech is probably a bit beyond what we have widely available, but is it that hard to come up with a multitude of common relationship issues and plug in data from our digital lives to see what our reactions are likely to be, and cross-reference it with our partner's likely choices? The real scary part is that people are apparently giving away their personal information to this company for what amounts to a cheesy dating app.
But yeah, there is no representation given about the accuracy of the simulation anywhere in the manga. Only thing that references it is that more information you provide, more trust/confidence/sense of reliability you can have on the result. Which is #1 an obvious point, and #2 a good way for the company to datamine the users even more thoroughly, so of course they'd say that.
