Mobile apps
|
- Cookies pertaining to advertising may be read and written.
- IP addresses are collected.
- The full web page URL, including ad-click information in URL parameters (e.g., GCLID / DCLID) is collected.
- Third-party web cookies previously set on google.com and doubleclick.net, and first-party conversion cookies (e.g.,
_gcl_* ) are accessible.
|
- Advertising identifiers (e.g., Advertising ID/IDFA) may be collected.
- The app-instance ID generated by the Google Analytics for Firebase SDK is collected.
|
When one or more forms of consent are not granted (not set or denied
), there are additional behaviors to consider:
ad_personalization='denied'
|
Web & Mobile apps
|
Personalized advertising is disabled, the following features won't receive data:

ad_user_data='denied'
|
Web & Mobile apps

Note: Both ad_user_data and ad_personalization need to be granted to enable personalized advertising in Google advertising platforms.
- Click-ID keyed conversion data export to Ads platform is limited, for example, bidding optimization in Google Ads based on GA4 conversions, when ad_user_data=denied.

ad_storage='denied'

- No new cookies pertaining to advertising may be written.
- No existing first-party advertising cookies may be read.
- Requests are sent through a different domain to avoid previously set third-party cookies from being sent in request headers.
- Google Analytics will not read or write Google Ads cookies, and Google signals features will not accumulate data for this traffic.
- Full page URL is collected, may include ad-click information in URL parameters (e.g., GCLID / DCLID). Ad-click information will only be used to approximate accurate traffic measurement.
- IP addresses are used to derive IP country, but are never logged by our Google Ads and Floodlight systems and are immediately deleted upon collection.
|
- No Advertising ID/IDFA may be collected.

analytics_storage='denied'
|
Web
|
Mobile apps
|
- Will not read or write first-party analytics cookies.
- Cookieless pings will be sent to Google Analytics for future measurement. Google Analytics 4 will use cookieless pings for modeling.
|
- No IDFV may be collected.
- Events without device or user identifiers will be sent to Google Analytics for future measurement. Google Analytics 4 will use these events for modeling.

Web & Mobile apps
When analytics_storage='denied' , cookieless pings are sent to Google Analytics. No Analytics cookies are set, accessed, or read from the device. Consequently, cookieless pings are anonymized and non-identifiable Google Analytics events.
Cookieless pings, as part of regular HTTP/browser communication, may include the following information: user agent, screen resolution, IP address. Note that Google Analytics 4 does not store or log IP addresses.
If an advertiser sets other fields, such as user_id and custom dimensions, they will be sent normally. The data collected in the cookieless ping is used for behavioral and conversion modeling, to fill the gaps in your data.
