What it is

AWS shares hashed contact information and cookie-based identifiers with advertising partners to enable personalized advertising on third-party websites and to measure advertising effectiveness. The notice states that directly identifying information such as name is not shared in this context.

ConductAtlas Analysis

Why it matters (compliance & governance perspective)

This provision authorizes transmission of derived personal identifiers to advertising partners for cross-context behavioral advertising purposes. Under CPRA, sharing personal information for cross-context behavioral advertising may constitute regulated sharing regardless of whether it is characterized as a sale, and the EEA section of the notice relies on legitimate interests as the legal basis for this processing under GDPR.

Interpretive note: Whether the hashed identifier and cookie sharing practice constitutes regulated sharing under CPRA or requires consent rather than legitimate interests under GDPR depends on jurisdiction-specific enforcement interpretation and regulatory guidance.

Consumer impact (what this means for users)

Under this provision, AWS transmits hashed email addresses and cookie identifiers to advertising partners, enabling personalized advertising on third-party sites. US users can opt out via the 'Your Privacy Choices' link in the AWS site footer; EEA users can withdraw consent via Cookie Preferences or submit the Your Privacy Choices form.

What you can do

We don't share your name or other information that directly identifies you when we do this. Instead, we use an identifier like a cookie or a unique code derived from your contact information (such as a hashed email address).
