Your reading settings, where you stopped and what you have read stay in this browser; the site never receives them.
To tell you what changed since your last visit, an article page sends the release you last read; it answers that question and is not kept.
A public article page also counts its reading anonymously: that it was opened, how far it was read in quarters, about how many seconds you were actively reading, in which section, and the domain of a site that linked here. No cookie is set and nothing identifies you or this device; the server keeps only daily totals, for 90 days. If your browser sends Global Privacy Control or Do Not Track, nothing is sent.
