Amazon Shopping

"Our physical stores may use cameras, computer vision, sensors, and other technology to gather information about your activity in the store, such as the products and services you interact with... device log files and configurations, including Wi-Fi credentials, if you choose to automatically synchronize them with your other Amazon devices."

Amazon collects extensive device data including Wi-Fi credentials, device logs, and uses cameras and sensors in physical stores to track customer behavior — going well beyond what's needed for basic e-commerce.

"As a result of those actions, you might supply us with such information as... your location information; your IP address... Amazon Services metrics (for example... location of your device running an application, information about uploaded images and files such as the file name, dates, times and location of your images)."

Amazon collects location data from devices, IP addresses, and even photo metadata, enabling broad location tracking across its services.

"Our business changes constantly, and our Privacy Notice will change also. You should check our websites frequently to see recent changes. Unless stated otherwise, our current Privacy Notice applies to all information that we have about you and your account."

Amazon can update its privacy policy at any time and applies changes retroactively to all existing data, placing the burden on users to check for changes rather than providing meaningful notice.

"Third-Party Service Providers: We employ other companies and individuals to perform functions on our behalf. Examples include fulfilling orders for products or services, delivering packages, sending postal mail and email, removing repetitive information from customer lists, analyzing data, providing marketing assistance, providing search results and links (including paid listings and links), processing payments, transmitting content, scoring, assessing and managing credit risk, and providing customer service."

Amazon shares personal data with a broad range of third-party service providers for functions including marketing, data analysis, credit scoring, and content delivery — a wide scope of sharing.

"When you update information, we usually keep a copy of the prior version for our records... Unless stated otherwise, our current Privacy Notice applies to all information that we have about you and your account."

Amazon retains old versions of user data even after updates, with no stated deletion timeline or retention limits.

"We may also use device identifiers, cookies, and other technologies on devices, applications, and our web pages to collect browsing, usage, or other technical information... information about your interactions with products and services offered by our subsidiaries... We use an advertising identifier like a cookie, a device identifier, or a code derived from applying irreversible cryptography to other information like an email address."

Amazon uses device identifiers, cookies, and hashed email addresses to track users across its ecosystem of services, subsidiaries, and third-party sites, building unified cross-service profiles.
