Notice on Cookies

Last Updated September 2023

Spark Therapeutics, Inc. (“Spark,” “we,” “our,” or “us”) may use one or more cookies or other tracking technologies (such as web beacons or pixels, collectively referred to herein as “cookies”) on the website www.sparktx.com and any other website or application on which the Notice appears (our “Sites”). This Notice on Cookies explains what cookies are and how we use them.

What are cookies?

Cookies are small data files stored on the hard drive of your computer or mobile device by a website. We may use both session cookies (which expire once you close your web browser) and persistent cookies (which stay on your computer or mobile device until you delete them) to provide you with a more personal and interactive experience on our Site.

We use two broad categories of cookies: (1) first party cookies, served directly by us to your computer or mobile device, which we use to recognize your computer or mobile device when it revisits our Sites; and (2) third party cookies, which are served by service providers on our Sites, and can be used by such service providers to recognize your computer or mobile device when it visits other websites.

Cookies we use

Our Sites use the following types of cookies for the purposes set out below:

Type of cookie	Purpose
Essential Cookies	These cookies are essential to provide you with services available through our Site and to enable you to use some of its features. Without these cookies, the services that you have asked for cannot be provided, and we only use these cookies to provide you with those services.
Functionality Cookies	These cookies allow our Sites to remember choices you make when you use our Sites. The purpose of these cookies is to provide you with a more personal experience and to avoid you having to re-select your preferences every time you visit our Sites.
Analytics and Performance Cookies	These cookies are used to collect information about traffic to our Site and how users use our Sites. The information gathered may include the number of visitors to our Sites, the websites that referred them to our Site, the pages they visited on our Sites, what time of day they visited our Sites, whether they have visited our Sites before, and other similar information. We use this information to help operate our Sites more efficiently, to gather broad demographic information, monitor the level of activity on our Sites, and improve our Sites. We use Google Analytics for this purpose. Google Analytics uses its own cookies. You can find out more information about Google Analytics cookies (here on Google's website) and about how Google protects your data here (in Google's privacy and terms section of its website). You can prevent the use of Google Analytics relating to your use of our Site by downloading and installing the browser plugin available from Google (here).
Targeted and advertising cookies	These cookies track your browsing habits to enable us to show advertising which is more likely to be of interest to you. These cookies use information about your browsing history to group you with other users who have similar interests. Based on that information, third party advertisers can place cookies to enable them to show advertisements which we think will be relevant to your interests while you are on third party websites. You can disable certain cookies that remember your browsing habits and target advertising to you by visiting www.youronlinechoices.eu (here) (for Europe) or visiting www.allaboutcookies.org (here) (for the United States). If you choose to remove targeted or advertising cookies, you will still see advertisements but they may not be relevant to you. Even if you do choose to remove cookies by the companies listed at the above link, not all companies that serve online behavioral advertising are included in this list, and so you may still receive some cookies and tailored advertisements from companies that are not listed.

How can you set your cookie preferences?

You can set up or change your cookies preferences for the Sites at any time by using our cookie management tool, which can be found here. You can change your web browser settings to notify you when cookies are set or to disable cookies altogether, including on our Sites. You can also delete cookies that have already been set. To manage your cookie preferences through your browser, you can follow the links below or find the cookie management instructions in the support page of your browser (the Help function within your browser should tell you how), depending on the browser you are using:

Please note that some functions on our Sites will not work properly if you choose to disable all cookies. For example, if you put in a password to access a restricted area, you will not be able to do so unless our Sites can authenticate you through cookies.
