ConductAtlas Analysis

Why it matters (compliance & governance perspective)

Ad targeting draws on multiple data sources simultaneously—off-platform business data, neighborhood-level demographics, and individual behavioral signals—creating a layered profile used to shape what advertising content each user sees.

Medium Jul 7, 2026

The updated footer no longer includes a direct link to the 'Do not Sell or Share My Personal Data' disclosure or control. Under California law and other US privacy regimes, platforms are required to provide clear and conspicuous access to consumer data sale opt-out mechanisms. If this link was the primary or most accessible pathway to that opt-out, its removal may complicate how users exercise statutory rights, though the underlying disclosure or control may remain available through other parts of the platform. Users should verify whether this opt-out functionality remains accessible through the main privacy policy page or account settings.

The updated footer no longer includes a direct link to the 'Do not Sell or Share My Personal Data' page. Previously, this link provided quick access to California Consumer Privacy Act (CCPA) opt-out controls from the footer menu. Users can likely still access these controls through the main Privacy Policy page or dedicated privacy settings, but the removal eliminates a prominent, footer-based navigation shortcut. You should verify whether this opt-out functionality remains accessible through other menu locations or settings.
