SAO/NASA ADS User Privacy Policy
The ADS respects the privacy of its users. The following describes our policy.
Server Logs
As you travel through the ADS web site, our server logs the following information about your session on the site:
We use this information from our server logs to learn about our visitors as a group, not about you as an individual. We also use the information to generate important statistics required by our funding sources. These records are kept only for the purpose of maintaining and improving services on our site, and are never shared with any other entity.
Cookies
A cookie is a unique identifier that a website places in your computer’s hard drive for future reference. The ADS uses cookies to allow customization of our site’s features on a user-by-user bases. For instance, the implementation of the ADS preference settings makes use of cookies.
Additionally, cookies offer a mechanism allowing us to track the sequence of documents that a particular user retrieves from our site, without having any knowledge of the user’s identity, and without requiring any form of user ID or password assignment. Again, this information is being collected only for the purpose of providing better service to our users. This permits, for instance, the creation of the “Also-read” article links, allowing users to see articles which were also read by people who read a given article.
Please note that our site does not require visitors to have cookies enabled in their web browsers. However, be reminded that some features of our system won’t be available to you if you choose to configure your browser not to use cookies.
Future Changes
The ADS reserves the right to change this policy at any time. If we make material changes to our privacy policy, these changes will be posted on this page.
