We use Tracking Technologies to allow the Website to operate, to increase its functionality and efficiency, to analyze how you use it so that we can improve it, and fulfill other legitimate purposes as described below.
To the extent that any information collected by the Tracking Technologies, either on its own or in combination with other information, constitutes Personal Data as the term is defined in our Privacy Notice, both our Privacy Notice and this Notice shall apply to the processing and transferring of such Personal Data.
Cookies and Other Tracking Technologies
Cookies. A cookie is a small text file stored on your device (computer, phone, tablet, etc.) that contains information about your browser and online activity. This information often consists of a string of numbers and letters that uniquely identifies your device.
We may also use:
Local Storage. Local storage enables our Website to store information locally on your device. Local storage may be used to improve your experience with our Website, for example, by enabling features, remembering your preferences and speeding up our Website functionality.
Local shared objects (a.k.a. “flash cookies”). Flash cookies are pieces of data that websites which use Adobe Flash may store on your device.
Pixels. A tracking pixel is a 1x1 pixel graphic used for the purpose of tracking user behavior, web traffic and site conversions. A tracking pixel allows us to collect data relating to the use of our Website. Tracking pixels are used to trigger advertisements on any participating websites based on the activity tracked from your browser or device and can also be used for third-party web analytics.
As noted above, we refer to all of these technologies collectively as “Tracking Technologies” in this Notice.
How We Respond to Do Not Track Signals / Online Tracking
“Do-Not-Track” is an optional browser setting that you can use to express your preferences regarding tracking by advertisers and other third-parties. Please note, however, that our Website does not have the capability to respond to “Do Not Track” signals received from web browsers at this time.
Opting Out
You can alter the configuration of your browser to reject certain types of Tracking Technologies, including cookies. Please note, however, that if you reject certain cookies, you may not be able to access and use all of the features on our Website. For more information about how to manage cookies, please visit https://www.aboutcookies.org/.
You may also control your online behavioral advertising preferences and opt out from having your data processed by certain marketing companies by visiting http://www.youronlinechoices.com/ and http://optout.aboutads.info/. Please note, however, that managing these preferences will not turn off internet advertisements in general. You will still receive the same number of advertisements, but those advertisements will be less reflective of your interests, as indicated by your web browsing habits. In addition, please note that the opt-out preferences that you set using these tools may be nullified if you delete your cookies after setting them.
Types of Cookies
We use session cookies and persistent cookies on our Website. The session cookies are deleted or removed when you close your browser. The persistent cookies may remain on your device after you close your browser, but they have an expiration date. Some of the cookies placed on your device through our Website are first-party cookies, meaning they are placed directly by us. Others are third-party cookies, meaning they are placed on your device through our Website by third parties, such as SquareSpace. In other words, when you visit our Website, certain third parties may place cookies on your device to collect information about your online activities over time and across different Internet websites or online services.
In some instances, the third parties listed below in this Notice may collect your data, including Personal Data, for their own business purposes. If this happens, the third parties would be acting as independent controllers of your Personal Data and are therefore independently responsible for complying with applicable data protection laws. Please directly contact the third parties if you wish to opt out from having your data processed by them for their own business purposes.
