Yahoo is now part of Oath, which includes a load (50+) of other brands, some fairly large. You might well not want your data shared amongst them. If so, here’s some useful links to help you trawl through the various settings and try to control the spread of your personal data.
EU Oath FAQ – includes answers to questions such as “How will my information be used? How will this help me as a user?”, “What user information is being shared?”, along with some links to opt out or configure data settings.
Yahoo Privacy Controls – A list of links to various settings. Most of the links on the rest of this post have originated on this page.
Unsubscribe from all Yahoo marketing and newsletters – Does what it says!
Ad Interest Manager – Use this to opt out of tailored advertising. Ensure you’re logged in to your Yahoo account on the browser where you view this page or the opt-out won’t be persistent. If you’re not logged in, it’s done by setting a cookie. Due to the use of a cookie, this then only applies to the device and browser where you view this page. Also see the Ad Interest Manager FAQ. Also see how Yahoo combines data they have on you with that from other sources.
Set the BrightRoll opt-out cookie – BrightRoll does video advertising, it’s another Oath brand.
