> Location History: Location History is a Google account setting that is off by default, and for those that turn it on, we provide simple controls like auto-delete so users can easily delete parts, or all, of their data at any time. Some of the places people visit — including medical facilities like counseling centers, domestic violence shelters, abortion clinics, fertility centers, addiction treatment facilities, weight loss clinics, cosmetic surgery clinics, and others — can be particularly personal. Today, we’re announcing that if our systems identify that someone has visited one of these places, we will delete these entries from Location History soon after they visit. This change will take effect in the coming weeks.
This seems to be pretty clearly what was happening, as described by the author of the article. *If* the systems detected an abortion clinic visit, it was deleted. No further guarantees were made in the blog post. The same post provides links to documentation on managing your location settings and history, so the user can adjust if they are unhappy with Google's behavior.
