To enable privacy settings for browser cookies
Many mobile apps (such as the in-app browser for Facebook or Twitter) can appear as a standard mobile browser but do not allow all cookies. Enabling this feature could exclude a high proportion of mobile traffic from Analytics reports.
About Browser Privacy Settings
Laws and regulatory guidance have expressed that a user’s action to block cookies is the same as a user’s action to opt out of profiling. By enabling this feature, data collected from desktop browsers, where the user has set the browser to block all cookies, are excluded from Analytics reports. If Adobe cannot recognize the web browser, data is included in Analytics reports.
Lawmakers around the world have stated (both in guidance and in settlements) that cookie browser settings are an indication of user preference to opt out of profiling. Specifically, these lawmakers have stated that the browser setting to block third-party cookies is an opt-out request from third-party (cross-site) tracking. Blocking out all cookies is an opt-out request for all tracking. While server-side identifiers (such as IP address or user agent) can be a desirable option that bypasses cookie browser settings, some lawmakers view them as a circumvention of user choice.
