Your tracking choices
We do not sell anyone’s information, and we do not share it in the sense the US state privacy laws use. We buy advertising on Google to bring people here and measure which of those ads worked, but we build no audiences from visitors and show no advertising on this site. The control below still stops this browser sending Google the signals used for advertising.
None of this touches survey answers, ratings or comments. The advertising tag runs on the public pages of this site and on nothing else — not on the app, and not on any page where someone answers a question about themselves or a colleague. What Google receives is that a browser visited a marketing page.
Stop sharing for this browser
The button applies to this browser on this device, for 12 months. It stops sharing with Google for advertising. Analytics measurement of the public pages continues, because it is a separate setting; a Global Privacy Control signal turns off both.
Global Privacy Control
If your browser or an extension sends a Global Privacy Control signal, we treat it as an opt-out automatically, on every page, without you visiting this one. It applies only in a browser or extension that sends the signal, not to your account or to your other devices, and clearing cookies does not undo it.
A GPC signal turns off analytics measurement as well as advertising, which is more than the law strictly requires. We do it because our analytics is linked to our advertising.
The privacy policy lists every cookie we set and what each one is for.
