Our pol­i­cy is clear:

We do not col­lect per­son­al­ly iden­ti­fi­able infor­ma­tion (PII) about you unless you choose to pro­vide that infor­ma­tion to us.  Any PII you chose to pro­vide is pro­tect­ed by var­i­ous 3rd par­ty secu­ri­ty con­trols pro­vid­ed by our host­ing ven­dors and Inter­net Ser­vice Providers. Non-PII infor­ma­tion relat­ed to your vis­it to our web­site may be auto­mat­i­cal­ly col­lect­ed and tem­porar­i­ly stored.

Information Collected and Stored Automatically

When you browse through our web­site, we gath­er and tem­porar­i­ly store tech­ni­cal infor­ma­tion about your vis­it. This infor­ma­tion does not iden­ti­fy who you are. The infor­ma­tion we col­lect includes:

The name of the domain you use to access the Inter­net (for exam­ple,, if you are using an Amer­i­can Online account, or, if you are con­nect­ing from Stan­ford University’s domain);
The date and time of your vis­it;
The pages you vis­it­ed; and
The address of the web­site you came from when you came to vis­it.
We use this infor­ma­tion to improve our web­site and pro­vide a bet­ter user expe­ri­ence for our vis­i­tors. We use a tool, Google Ana­lyt­ics and Bing Ana­lyt­ics to col­lect and aggre­gate this infor­ma­tion. This infor­ma­tion is avail­able only to web man­agers and oth­er des­ig­nat­ed staff who require this infor­ma­tion to per­form their duties. It is retained only for as long as need­ed for prop­er analy­sis.

Web Measurement and Customization

We use web mea­sure­ment and cus­tomiza­tion tech­nolo­gies, such as cook­ies, to help our web­site func­tion bet­ter for vis­i­tors and to bet­ter under­stand how the pub­lic is using our web­site.

Cookies uses “cook­ies” to test and opti­mize our web­site design and con­tent. A cook­ie is a small text file auto­mat­i­cal­ly placed on your com­put­er. We use two types of cook­ies on our web­sites:

We use ses­sion cook­ies to gath­er data for tech­ni­cal pur­pos­es, such as enabling bet­ter nav­i­ga­tion through our web­site and gen­er­at­ing aggre­gat­ed sta­tis­tics about how the web­site is used. Ses­sion cook­ies are tem­po­rary text files that expire when you leave our web­site. When cook­ies expire, they are auto­mat­i­cal­ly delet­ed from your com­put­er. We do not use ses­sion cook­ies to col­lect PII, and we do not share data col­lect­ed from ses­sion cook­ies. Our use of ses­sion cook­ies is defined as “Tier 1″ usage in accor­dance with the OMB Mem­o­ran­dum (M)-10–22 Guid­ance for Online Use of Web Mea­sure­ment and Cus­tomiza­tion Tech­nolo­gies.

We use mul­ti-ses­sion cook­ies, a.k.a. per­sis­tent cook­ies, to cus­tomize our web­site for fre­quent vis­i­tors and to test vari­a­tions of web­site design and con­tent. Mul­ti-ses­sion cook­ies are cook­ies that are stored over more than a sin­gle ses­sion on your com­put­er. We do not use mul­ti-ses­sion cook­ies to col­lect PII, and we do not share data col­lect­ed from mul­ti-ses­sion cook­ies. Our mul­ti-ses­sion cook­ies are set to expire two years after your last vis­it to our web­site. After two years, they are auto­mat­i­cal­ly delet­ed from your com­put­er. Our use of mul­ti-ses­sion cook­ies is defined as “Tier 2″ usage in accor­dance with the OMB Mem­o­ran­dum (M)-10–22 Guid­ance for Online Use of Web Mea­sure­ment and Cus­tomiza­tion Tech­nolo­gies.

You can take actions to block cook­ies. Block­ing these cook­ies from your com­put­er will not affect your access to the con­tent and tools on our web­site. Instruc­tions to opt out are avail­able on
