Shop with less tracking: accounts, cookies and ad settings
A United States guide to reducing shopping-site tracking with browser and phone settings, without a carbon claim.

Shopping sites often include ads, analytics and personalization on top of the product page. We do not claim a carbon or bandwidth number for reducing that, because it varies by site and device. This guide is about privacy and tidiness: fewer accounts, narrower cookies and clearer ad settings. ECOA's methodology treats any estimate as educational.
The FTC explains that websites use cookies, pixels and device fingerprinting to identify people across visits, and that companies collect data to show personalized ads based on browsing history or location. FTC: how websites and apps collect information
Keep accounts you use
Make a list of the shops where you have an account. Keep the ones you use, and consider checkout as a guest for a one-off purchase when a shop allows it. Before deleting an account, check the shop's own steps and any order or warranty records you may need. This is our habit suggestion, not a legal rule.
Narrow the cookies
CISA recommends blocking third-party cookies while allowing first-party cookies needed for a site to work, and managing ad personalization. CISA: browser settings CISA's tracking guidance lists disabling Ad IDs among its defenses. CISA: tracking technologies A shop may behave differently after you block cookies, such as forgetting your cart, so test with a small purchase.
Review app permissions
Shopping apps may ask for location, contacts or photos. The FTC suggests reviewing smartphone privacy settings and considering disabling unnecessary permissions. If you rarely use an app, using the shop's website in a browser is an alternative, depending on the shop.
Try one change
Pick one: block third-party cookies, turn off ad personalization on your phone, or remove one shopping app you do not use. Note whether shopping felt simpler. That is a personal observation, not a measured effect.
