| IP addresses |
“Google Analytics does not log or store individual IP addresses from EU, Switzerland, or UK users.” Their IP is used for a rough location, then discarded. |
Built in |
Nothing to switch on. The old “anonymise IP” code was for Universal Analytics. |
| EU data collection |
“Google Analytics collects all data from EU, Switzerland, or UK-based devices” through servers in those regions, before it goes on to be processed. |
Built in |
Nothing to do, unless your Content Security Policy needs *.google-analytics.com and *.analytics.google.com. Processing can still happen in the US, which is why the transfer layer matters. |
| Google signals |
For users who turned on ad personalisation and signed in to Google, “reporting data is enriched” with demographics and a view across their devices. It can be switched per region. |
Admin › Data collection and modification › Data collection |
Off for the EEA, the UK and Switzerland, unless your banner asks for marketing consent and you need those reports. |
| Granular location and device data |
City, device model, screen resolution, browser and OS minor versions. “Analytics collects this data by default”, and you can turn it off per region. |
Admin › Data collection and modification › Data collection |
Off for Europe if you don’t read city or device-model reports. Google warns that modelled key events fall in that region. |
| Data retention |
User-level and event data are kept 2 or 14 months on a standard property, 26 to 50 on Analytics 360. The setting limits explorations and funnel reports; standard reports aren’t affected. |
Admin › Data settings › Data retention |
2 months, unless you run explorations further back. Write down why if you pick longer. |
| Data sharing |
With “Google products & services” on, Google says it is “an independent controller” of that data. Off, it works only as your processor, under the Google Ads Data Processing Terms. |
Admin › Account details |
Off, along with any other sharing you don’t need. It also matters for the UK’s statistics exception, which wants the provider to be your processor. |
| User-ID and personal details |
You must not pass information, “hashed or otherwise”, that Google “could use or recognize as personally identifiable information”. |
Your tag, events and page URLs |
An internal, random ID at most. Watch for emails in URLs, such as a thank-you page with ?email=. |
| Consent Mode |
“Consent mode doesn’t provide a consent banner or widget.” It passes your banner’s answer to Google’s tags. |
Your banner, first in <head> |
Basic mode for the EU: no Google tag until a yes. The Consent Mode v2 guide builds the code. |
