To make the WWF2 Letter Lab site work properly, we sometimes place small data files called cookies on your device. Most big websites do this too.
What are cookies?
A cookie is a small text file that a website saves on your computer or mobile device when you visit the WWF2 Letter Lab site.
What cookies do we use and how do we use them?
A number of our pages use the following cookies for the following purposes:
- to recognize you when you connect to the WWF2 Letter Lab website so as to personalize the user's interface.
- to facilitate the management of WWF2 Letter Lab.
- for statistical purposes (pages consulted, date and time of consultations etc.), for example Google Analytics.

Enabling some of these cookies is not strictly necessary for the website to work but it will provide you with a better browsing experience. You can delete or block these cookies (see «How to control cookies»), but if you do that some features of this site may not work as intended.
Cookies are not used for any purpose other than those described here and will not affect the performance of your computer.
What is Digital Finger Printing and how do we use it?
In general, Digital Fingerprinting technologies assign a unique identifier or "Machine-ID" to a user's computer to identify and track the computer. Toluna will not use Digital Fingerprinting technology (the "technology") to collect personal information, or track the online activities, of the user of a computer; and will not disrupt or interfere with the use or control of a computer or alter, modify or change the settings or functionality of a computer. Toluna will use the technology to assist WWF2 Letter Lab and other Toluna clients in ensuring the integrity of survey results. The technology will analyze publicly available information and data obtained from the computer's web browser and from other publicly available data points, including without limitation the technical settings of the computer, the characteristics of the computer, and the computer's IP Address, to create a unique identifier assigned to the computer. The unique identifier will be an alpha-numeric ID. After creating the unique identifier, Toluna does not retain the information ID used by the Technology to create the unique identifier.
In the event that Toluna discovers or learns of any unethical conduct in connection with the use of the above technology, or that the technology is being used in a manner that is inconsistent with the statements and/or disclosures made by Toluna to respondents or in violation of applicable Laws and Codes, Toluna will take immediate action to prohibit such unethical conduct and to ensure the proper administration of the technology.
For US Members only: Many browsers including Internet Explorer, Firefox, and Google Chrome contain a "do not track" optional setting. In general, when a "do not track" setting is active, the user's browser notifies websites that the user does not want the user's personally identifiable information about an individual consumer's online activities tracked over time and across different Web sites or online services. Websites are not required to honor a do not track request and as required by amendments to the California Shine the Light law, we are informing you that we do not honor such requests.
