Ancestry cookie policy electricity and magnetism notes


At Ancestry, customer trust is our top priority and how we use cookies is integral to keeping that priority. This cookie policy explains what cookies are, the different types of cookies, how we use them and most importantly how to control your cookies.

Most websites you visit use cookies to improve your online experience – and we are no different. Essentially, they are small text files, stored in your browser or on your hard drive, that allow us to differentiate between you and all our other visitors.

These cookies are only stored on your device (which may mean a desktop computer, laptop, tablet or mobile phone) during a single visit to the site (called a ‘browser session’). They do not do anything unless you are actively browsing, and they are deleted as soon as you close your browser.

First-party cookies are cookies that belong to Ancestry whereas third-party cookies are cookies that another party places on your browsing device through our websites. Third-party cookies will be providing a service to Ancestry or a function to us but Ancestry cannot control how those third-party cookies are used.

If you use buttons to share online content with your friends via social networks like Twitter and Facebook, these companies may set a cookie on your computer or other device (laptop, tablet or mobile phone). Find out more about these cookies here:

These cookies do things like ensure that your password works and you stay logged in when you move between pages on the site and help the site to remember details like what is in your shopping basket or how far you are through an order. They also keep you secure while you are logged in and help to ensure the site looks consistent during your visit.

These cookies collect information about how you use our site, such as which pages you visit and if you experience any errors. They do not collect anything that could identify you as it is aggregated data and we only use them to improve how our site works, understand what interests our users, and measure how effective our content is. Our performance cookies include: (a) web analytics to provide information on how our site is used (b) error management to help us improve the site by measuring any errors that occur (c) site preferences to remember details such as how you have set up your home page, or the home person in your family tree.

Advertising cookies collect information about browsing habits. We use them to make sure our advertising and suggestions are relevant to you and your interests (you will also hear this referred to as online behavioral advertising) and to limit the number of times you see an advertisement. We work with third parties who do this for us and we sometimes also place ads around our sites. You can opt out of some targeting cookies – see “How can I opt out of interest-based advertising?” below for more information.

We also use tracking pixels (a.k.a. web beacons, action tags, or clear gifs), that help us better manage content on our site by informing us what content is effective. Tracking pixels are tiny graphics with a unique identifier, similar in function to cookies, and are used to track the online movements of website users in combination with other information we know about our users. We also use pixels in our HTML-based emails to let us know which emails have been opened by recipients. This allows us to gauge the effectiveness of certain communications.

We use cookies on our sites (such as and and mobile applications. If a browser visits these sites they will receive a cookie from Ancestry. Cookies are also placed in your browser when you visit non-Ancestry sites that host our plugins.

Ancestry uses cookies to deliver content and advertisements specific to your interests on our sites and elsewhere on the Internet. Ancestry uses some third parties to show you Ancestry-related advertisements that are tailored to you based upon your interests or online behaviors.

Please note: Ancestry allows third-party advertisers that are presenting advertisements for us to set and access their cookies, pixels, tags, and scripts on your computer. The advertisers’ use of cookies and these other technologies is subject to their own privacy policies.

Ancestry notes that although we do our best to honor your privacy preferences, and have implemented industry standard safeguards as described above, we do not respond to Do-Not-Track signals from your browser at this time due to the lack of an established industry standard. Ancestry uses advertising technology to show you advertising relevant to your Ancestry experience. Also, when Ancestry uses other companies’ services, data, and software tools to target advertising to you, these companies may collect information (such as a unique cookie or mobile identifier) about your online activities over time and across other websites or services on our behalf.

Any interest-based advertising placed on Ancestry’s behalf will contain information on or near them that informs you about the third-party delivering you the ads and how to opt out of receiving similar ads from that party in the future. If you do not see any information about how to opt out of receiving these ads, you are likely receiving a generic ad that was not specifically targeted towards you.
