This article is about the app, which does not run the model locally. Why would you doubt that a Chinese app which openly claims they send your data to China, actually does so?
It seems like a smear piece because it makes it sound like DeepSeek is doing something that the others aren't, while the truth is that ever single on of them collects your data.
At best, it's disingenuous. At worst, with the ability to run locally, it's a blatant lie.
