F. Special Information for Connecticut Residents

The Connecticut Data Privacy Act ("CTDPA") provides Connecticut residents with the right to receive certain disclosures regarding the personal data we process about them. For purposes of this Section, personal data means any information that is linked or reasonably linkable to an identified or identifiable individual. Personal data does not include de-identified data or publicly available information as the CTDPA defines those terms.

For a discussion of the categories of personal data we process, the purposes for our processing, the categories of personal data that we share with third parties, and the categories of third parties with whom we share personal data, please see Sections A through C, above, and Section G, below.

If you are a Connecticut resident, the CTDPA provides you the following rights with respect to your personal data:

  • The right to confirm whether or not we are processing your personal data and to access such personal data;
  • The right to obtain a copy of your personal data that we collected from and/or about you in a portable and, to the extent technically feasible, readily usable format that allows you to transmit the information to another controller without hindrance, where the processing is carried out by automated means;
  • The right to delete personal data that we collected from and/or about you, subject to certain exceptions;
  • The right to correct inaccurate personal data that we maintain about you, subject to certain exceptions;
  • The right, if applicable, to opt out of the processing of your personal data for purposes of (1) targeted advertising, (2) the "sale" of your personal data (as that term is defined by the CTDPA), or (3) profiling in furtherance of solely automated decisions that produce legal or similarly significant effects concerning you;
  • If we obtain your consent to process sensitive personal data, the right to withdraw your consent; and
  • The right not to receive discriminatory treatment by us for the exercise of privacy rights the CTDPA confers.

We do not sell personal data in the conventional sense.  However, like many companies, we use cookies and other tracking technologies to display advertisements about our Services to you on nonaffiliated websites, applications, and online services. This is “targeted advertising” under the CTDPA. When we engage in those activities, we sell personal data (i.e., information from cookies) to third-party advertisers and analytics companies. We do not use personal data for profiling in furtherance of solely automated decisions that produce legal or similarly significant effects concerning individuals. 

To exercise your rights, please submit a request through our interactive webform available here or by calling us at 844-636-1244 . If legally required, we will comply with your request upon verification of your identity and, to the extent applicable, the identity of the individual on whose behalf you are making such request. To do so, we will ask you to verify data points based on information we have in our records. If you are submitting a request on behalf of another individual, please use the same contact methods described above. If we refuse to take action regarding your request, you may appeal our decision by replying to our denial or emailing us at If you would like to opt out of targeted advertising, you may alter your cookie preferences here.

G. Special Information for California Residents

If you are a California resident, you have the right under the California Consumer Privacy Act (“CCPA") to receive notice of the categories of personal information we collect, the purposes for which those categories of personal inform­ation will be used, and how we determine the length of time for which the personal information is maintained. You are also entitled to receive notice regarding your rights under the CCPA. 

Collection, Use, and Retention – Business Customers and Prospective Business Customers

We collect personal information subject to the CCPA where we interact with representatives or agents of our business customers or other business contacts who are located in California or when residents of California visit our websites.

California law requires us to provide information regarding the criteria we use to determine the length of time for which we retain personal information.

We utilize the following criteria to determine the length of time for which we retain information:

  • The business purposes for which the information is used, and the length of time for which the information is required to achieve those purposes;
  • Whether we are required to retain the information type in order to comply with legal obligations or contractual commitments, to defend against potential legal claims, or as otherwise necessary to investigate theft or other activities potentially in violation of Constellation’s policies and procedures applicable to you or against the law, to ensure a secure online environment, or to protect health and safety;
  • The privacy impact of ongoing retention on the consumer; and the manner in which information is maintained and flows through our systems, and how best to manage the lifecycle of information in light of the volume and complexity of the systems in our infrastructure.

Individual pieces of personal information such as those listed above may exist in different systems that are used for different business or legal purposes. A different maximum retention period may apply to each use case of the information. Certain individual pieces of information may also be stored in combination with other individual pieces of information, and the maximum retention period may be determined by the purpose for which that information set is used. 

The following chart describes our practices with regard to the collection, use, and retention of personal information. We use categories to describe the information we process that are listed in the CCPA. Certain personal information may fall into multiple categories. Some of the categories include very different types of information. As a result, how we use and how long we keep the information within each category will vary.

The examples of personal information listed below are illustrative and do not represent a complete description of the information we process.


Required Information


Name, email address, phone number, business or other contact address
Source: Directly from you or from the business entity you represent
Purpose of collection and use: The purposes listed in Section B above
Retention considerations: The amount of time we retain your identifiers will depend on your relationship with the business you represent

Internet or other similar network activity

Device ID, browsing history, search history, and information regarding your interaction with our website, application, or advertisement
Source: Automatically generated when you use our websites or applications
Purpose of collection and use: All purposes listed in Section B  above
Retention considerations: Internet or other network activity information is typically deleted at regular intervals when the information is no longer necessary for the purposes for which it is collected

Purpose of collection and use: The purposes listed in Section B above
Retention considerations: The law requires us to maintain purchase records for a period of time, which varies by state


Constellation does not collect the following categories listed in the CCPA for current and prospective business customers: protected classifications, biometric information, geolocation data, education information, inferences, or sensory data.

Sale and Sharing

The CCPA also requires us to list the categories of third parties to whom we “sell” or “share” personal information. Under the CCPA, a business “sells” personal information when it discloses personal information to a company for monetary or other benefit. We are required to list entities to whom we disclose information to conduct activities on our behalf, as described in Section C above. These entities are restricted from using personal information for any purpose that is not related to our engagement.



Required Information


Unique personal identifier, online identifier, internet protocol address, or other similar identifiers
Categories of parties with whom personal information is sold: Advertising networks; Data analytics providers
Categories of parties with whom personal information is shared: Service providers

Internet or other similar network activity

Information regarding your interaction with an internet website, application, or advertisement
Categories of parties with whom personal information is sold: Advertising networks; Data analytics providers
Categories of parties with whom personal information is shared: Service providers



As a California resident, you have the right to request access to personal information collected about you and information regarding the source of that personal information, the purposes for which we collect it, and the third parties and service providers with whom we share it. You also have the right to request we correct inaccurate information, and to request in certain circumstances that we delete personal information that we have collected directly from you. You have the right to be free from discrimination based on your exercise of your CCPA rights.

You may submit a request to exercise your rights to access, correct, or delete your personal information through one of two means:

  • By completing the form available here
  • By calling us at 1-844-636-3749

We may have a reason under the law why we do not have to comply with your request, or why we may comply with it in a more limited way than you anticipated. If we do, we will explain that to you in our response. Upon submission of your request, we will contact you (via the email address provided in your request) with instructions on how to verify the request, after which we will check our records for matching information, and aim to complete requests as soon as reasonably practicable and consistent with any applicable laws. You may authorize another individual or a business registered with the California Secretary of State, called an authorized agent, to make requests on your behalf through these means. 

If you are a California resident, you also have the right to direct us to stop selling or sharing your personal information to third parties. You may submit a request to opt out of sales or sharing by visiting our Your Privacy Choices page.  If you have enabled privacy controls on your browser (such as a plugin), we will also treat that as a valid request to opt out. Please see the “Universal Opt-Out Mechanisms” portion of Section D above for more information.

The CCPA also grants you the right to request that we limit use of sensitive personal information to certain purposes allowed by law. However, we do not use sensitive personal information in any way for which you would be afforded this right.

H. Children’s Privacy

We do not knowingly collect information from children under 13 years of age, nor will we knowingly allow children under 13 years of age to use certain features of our website. If we become aware that a child under 13 years of age has provided us with personal information, we take immediate steps to delete such personal information.

J. Biometric Information Policy

The Illinois Biometric Information Privacy Act (BIPA) regulates the collection, use, and retention of a person's biometric identifiers or information (biometric data).  It requires collectors of this information to, among other things, establish a retention schedule and guidelines for permanently destroying biometric data when the initial purpose for collecting or obtaining such biometric data has been satisfied or within 3 years of the individual's last interaction with the private entity, whichever occurs first. 

Constellation Energy Generation, LLC (Constellation Generation) is the largest operator of commercial nuclear power plants in the United States.  As part of its extensive efforts to ensure the security of these facilities and to comply with federal government regulations, Constellation Generation collects biometric data in the form of fingerprints and hand geometry scans from persons who apply for and persons who are granted unescorted access to one or more of its nuclear power plants or to Safeguards Information.  The collection of fingerprints for these purposes is required by Section 149 of the Atomic Energy Act of 1954, as amended, and the regulations of the United States Nuclear Regulatory Commission (NRC) at 10 CFR §§ 73.55, 73.56, and 73.57.  Upon collection, Constellation Generation transmits these fingerprint files electronically to the NRC to provide to the Federal Bureau of Investigation for the purpose of conducting criminal history records checks.  The results of the criminal history records checks are provided to and used by Constellation Generation as part of its determination of the trustworthiness and reliability to hold unescorted access or have access to Safeguards Information. 

Fingerprint files collected by Constellation Generation are securely stored and transmitted by Constellation Generation to Government entities using a reasonable standard of care within the nuclear industry. Constellation Generation periodically destroys the fingerprint files it collects once the initial purpose of collection has been satisfied, not to exceed three years.  After the fingerprint files are transmitted to the Government entities, Constellation Generation retains a secure copy of the electronic file for a period of time in case the data becomes corrupted in transmission. The electronic files are periodically deleted based on the date the electronic file was created, but within a three-year period.

Constellation Generation collects hand geometry scans of persons granted unescorted access for the purpose of verifying the identity of persons who have already been granted unescorted access prior to each entry into the protected area of its nuclear power plants. For Constellation Generation’s Illinois-based nuclear plants, hand geometry data is stored in a secure system and is evaluated, typically every thirty days.  All hand geometry data for persons who no longer require unescorted access to the facility is deleted as part of that evaluation.

Constellation Generation does not sell, lease, trade, disclose, redisclose, disseminate, or profit from a person’s biometric data.

Additional information regarding the NRC's requirement for access authorization and physical protection of nuclear power plants can be found on the NRC's website at
