How Amazon knows so much about you – and how to regain your privacy

1-Click ordering is automatically enabled for you when you first buy something from Amazon. Amazon gets information from the credit card details and shipping address you gave it when you made your first order.

If you click "Buy now with 1-Click" your order is automatically charged to the default payment method on your account and shipped to your default address. This lets you bypass the shopping cart and speeds up your order.

To change this setting, go to the "Manage Addresses and 1-Click Settings" link. You can delete addresses and payment methods as you wish.

Amazon stores information about you when you add something to your wish list. You can search for lists created by other people and add items to your own list. Amazon tracks your wishes to suggest items to you and to your friends about what you might like to receive.

Delete items from your wish list if you do not want to give this insight to Amazon.

If you visit a site that has Amazon content on it, such as a recommended book or item, Amazon could display interest based ads to you even when the site is not affiliated to Amazon itself.

The site could contain Amazon content or ads, it might interact with Amazon tools or use an Amazon payment service. Amazon reads your browser cookies to learn what ads you see and click on. It then provides you with more relevant ads.  

You can choose not to receive personalised ads such as ads based on your interest or the products you have viewed or purchased on Amazon.

You can also opt out from online behavioural advertising from ad networks who follow the digital Advertising Alliance’s self regulatory principles for online behavioural advertising.

Any information that you have given Amazon when you purchase something is stored in your account settings. If you have used a different email address, you will have more than one account. You might have added activities to your profile, stated your home city, your occupation, or filled in the "About Me" box.

Amazon will use this information to suggest relevant items for you to purchase. Amazon also allows you to connect with your friends on Amazon to enable them (and Amazon) to learn more about you.

If you are not comfortable with the information that Amazon has, use the links in your account settings page to remove any data you want.
