The MSK Release of Information Requester Portal (the “Portal”) is operated by Memorial Sloan Kettering Cancer Center (“MSK,” “we”, “our” or “us”). MSK is committed to the individual privacy of every user (defined below) of the Portal.

What this Policy Covers
This Privacy Policy describes how we collect, use, and disclose the Personal Data (defined below) that we collect or receive through the Portal. When we say the “Portal” we mean collectively:
- The MSK Release of Information Requester Portal website; and
- Any other webpages or mobile applications that link to this Privacy Policy.
The Portal is made available to third-party organizations and their authorized users to permit them to request MSK patient medical records which they are legally permitted to access. All users of the Portal described above are collectively referred to in this Privacy Policy as “users”.
The Information We Collect and Use
Patient medical records include patient health information known as Protected Health Information (“PHI”), which is regulated under the Health Insurance Portability and Accountability Act of 1996 (HIPAA). PHI includes certain information that is (a) created or received by a health care provider and relates to an individual’s past, present, or future physical or mental health or condition, health care provided to an individual, or the past, present, or future payment for health care provided to an individual; and (b) that identifies the individual or with respect to which there is a reasonable basis to believe the information can be used to identify the individual. Please review our Notice of Privacy Practices (HIPAA) for information on how we may use and disclose PHI.
When we use the term “Personal Data” we mean information that we directly associate with a specific person, or that we can reasonably use to identify a specific person such as a name or email address. Any Personal Data we collect through The Portal that is also PHI will be handled as further described in our Notice of Privacy Practices (HIPAA). We collect and use Personal Data and PHI through your use of The Portal in the following ways:
1. Personal Data You Provide to Us
We collect Personal Data when you choose to share that information with us, including in the following ways.
All The Portal Users:
- When you set up a Portal account, you will be asked to submit Personal Data which could include your name, mailing address, email address, phone number, fax number, and the address to which the requested records should be delivered. We use this information to set up and administer your Portal account and process your records requests.
- When you submit a request for Patient information, you will be asked to submit Personal Data which could include the Patient’s name, date of birth, social security number, legal sex, mailing address, phone number, and medical record number. You will also be asked to submit a signed authorization to release PHI, which may include your Personal Data and that of the Patient whose records you are requesting.
- We may collect information and use it to manage how we communicate with you. For example, we may use your email address to alert you that you have a message waiting in the Portal.
2. Information We Collect Automatically
We use certain technologies on the Portal to automatically collect information during your use of The Portal (“Other Information”). If we associate Other Information with Personal Data, we will treat the combined information as Personal Data in accordance with this Privacy Policy.
The technologies we use to collect Personal Data and other information include the following:
- Web Log File Data. Like most other websites or mobile applications, we collect some basic information automatically about you and store it in log files. This information may include IP address, browser type, internet service provider, pages you visit from and pages you go to after leaving the Portal, pages you visit on the Portal, date and time stamp, and clickstream data. We use this information for Portal management and administration, to improve the content, overall performance and user experience on the Portal, for fraud protection and for protecting our rights.
- Data from Cookies and Other Data Collection Technologies. We and our service providers use cookies, web beacons and similar technologies to manage the Portal and to collect information about you when you use the Portal. These technologies help us to recognize you, analyze your use of the Portal and identify solutions for how to make the Portal more useful. These technologies also allow us to enhance the usability of the Portal by aggregating demographic and statistical data and providing this information to our service providers.
- Information for Analytics. We use analytics providers to help us track certain information about your activity in the Portal, and to evaluate and measure the use and performance of the Portal. We may combine this information with other information we have about you to help us improve the Portal and our service to you.
Please see more information on analytics and data collection technologies and the choices you can make in the “Your Online Choices” section of this Privacy Policy.
3. Additional Uses of Personal Data
In addition to the uses described above, we may, consistent with our other legal obligations, use your Personal Data for the following purposes:
- Maintaining, delivering and improving the Portal and our services;
- Contacting you to respond to your requests or inquiries and provide support;
- Send you technical notices, updates, security alerts and support and administrative messages;
- Developing new resources and services;
- Conducting, managing and growing our business operations;
- Preventing, investigating and providing notice of fraud, unlawful or criminal activity or unauthorized access to or use of Personal Data, the Portal or our data systems, or to meet legal obligations;
- Investigating and resolving disputes and security issues and enforcing our Requestor Portal Terms of Use and End User License Agreement; and
- Carrying out any other purpose for which the information was collected.
We also may use aggregated or de-identified information, which cannot reasonably be used to identify you. Once de-identified and aggregated so that data does not personally identify you (for example, we may aggregate data in order to improve our automation and improve care), it is no longer Personal Data. Such de-identified or aggregated information which does not identify individuals is not subject to this Privacy Policy.
How We Disclose Personal Data
We may disclose Personal Data collected through the Portal as described in the sections above, for the reason(s) provided to you at the time we collect it, with your authorization or consent, and in the following ways:
- Third-Party Service Providers. We may disclose Personal Data to vendors who perform services on our behalf, including, but not limited to helping us manage the Portal and our Patients’ medical records, manage our communication channels and conduct analytics, and providers involved in hosting and monitoring the Portal. Vendors with whom we share Personal Data that is PHI are called business associates. We will have a written contract with these business associates that makes sure they also protect the privacy of PHI.
- Affiliates. We may disclose Personal Data between and among MSK and our current and future parents, affiliates, subsidiaries and other companies under common control and ownership. For example, MSK and MMC participate in an Organized Health Care Arrangement (OHCA), which allows MSK and MMC to share PHI and Personal Data collected in the Portal with each other to carry out treatment, payment, and joint health care operations activities that relate to the OHCA.
- Legal Process, Safety and Terms Enforcement. We may disclose your Personal Data to legal or government regulatory authorities in response to a search warrant, subpoena, court order or other request for such information or to assist in investigations. We may also disclose your Personal Data to third parties in connection with claims, disputes or litigation, when otherwise required by law, if we determine such disclosure is necessary to protect the health and safety of us or our users or to enforce our legal rights or contractual commitments that users have made.
- Business Transfers. We may disclose Personal Data as a part of a corporate business transaction, such as a merger, acquisition, reorganization, divestiture, dissolution, joint venture or financing, bankruptcy or sale of all or a portion of our assets.
Security
We seek to use reasonable physical, technical, and administrative measures designed to protect Personal Data within our organization. Unfortunately, no data transmission or storage system can be guaranteed to be 100% secure. If you have reason to believe that your interaction with us is no longer secure (for example, if you feel that the security of your account has been compromised), please immediately notify us as described in the “Contact Us” section below.
Links to Other Websites or Mobile Applications
The Portal may contain links to websites or mobile applications owned and operated by third parties. Other websites may also reference or link to the Portal. These other web sites are not controlled by MSK. A link to a third party’s website or mobile application does not imply an endorsement of that website’s or mobile application’s content or services. This Privacy Policy does not apply to, and we are not responsible for, the privacy practices of third-party websites or mobile applications that are not owned by us. We encourage you to read privacy statements of any third-party websites or mobile applications to learn about their information practices. Visiting these other websites and mobile applications is at your own risk.
How we Respond to “Do Not Track” Signals
Some web browsers have “Do Not Track” or similar features that allow you to tell each website you visit that you do not want your activities on that website tracked. At present, The Portal does not respond to “Do Not Track” signals and consequently, the Portal will continue to collect information about you even if your browser’s “Do Not Track” feature is activated.
Notices to Individuals Located Outside of the United States
- Notice to Individuals Located in the United Kingdom, European Economic Area, and Switzerland
This Privacy Policy describes ways in which you may provide information to MSK using the MSK Release of Information Requester Portal (“MSK ROI Requestor Portal”). Personal Data about individuals located in the European Economic Area, United Kingdom, or Switzerland (generally referred to here as the “EU”) are subject to special protections under EU law when the processing of those data are within the scope of the European Union’s General Data Protection Regulation (EU Regulation 2016/679), its incorporation into the laws of England and Wales, Scotland, and Northern Ireland by virtue of the UK European Union (Withdrawal) Act 2018 and/or the Swiss Federal Act on Data Protection, as applicable (together, the “GDPR”). This Notice to Individuals Located in the United Kingdom, European Economic Area, and Switzerland (the “GDPR MSK ROI Requester Portal Notice”) applies to MSK’s processing of Personal Data that is within the scope of the GDPR, which we call collectively the “GDPR Processing Activities.” This GDPR MSK ROI Requester Portal Notice applies only to GDPR Processing Activities involving Personal Data collected through the MSK ROI Requester Portal. When you use the MSK ROI Requester Portal to transfer your Personal Data to MSK in the United States for GDPR Processing Activities, MSK is a controller of this Personal Data.
We rely on separate and overlapping bases to process your Personal Data lawfully. MSK will use the Personal Data provided through or collected on the MSK ROI Requester Portal only for the purposes described in this Privacy Policy. MSK’s legal bases for processing your Personal Data include providing you with the information or services that you have requested, protecting your vital interests, furthering our legitimate interests, and your consent, if applicable. When we process special categories of Personal Data, including data concerning your health, our legal bases for processing such data include protecting your vital interests, furnishing a medical diagnosis, performing preventive or occupational medicine or assessment of the working capacity of our workforce, carrying out our obligations under employment or social protection laws, and your consent, if applicable. Legitimate interests that we rely on in processing your Personal Data include (i) improving and customizing the MSK ROI Requester Portal for you, (ii) understanding how the MSK ROI Requester Portal is being used, (iii) exploring ways to develop and grow our operations, (iv) ensuring the safety and security of the MSK ROI Requester Portal, and (v) enhancing protection against fraud, spam, harassment, intellectual property infringement, crime and security risks. Without the ability to collect and process your Personal Data, MSK would not be able to achieve those interests. We may also use your Personal Data for purposes, including scientific research if applicable, that are compatible with the purposes for which such data were initially collected.
If our processing is based solely on consent, you have the right to withdraw your consent. You may withdraw your consent by contacting us as set forth in the “Contact Us” section below. Please note that, in certain cases, we may continue to process your Personal Data after you have withdrawn consent, if we have a legal basis to do so. For example, we may retain certain information if we need to do so to comply with an independent legal obligation, or if it is necessary to do so to pursue our legitimate interest in keeping the MSK ROI Requester Portal safe and secure, or if deleting the information would undermine the integrity of a research study in which you are enrolled.
MSK is located in the United States. When you enter your Personal Data through the MSK ROI Requester Portal, the data is being transferred to, stored, and processed in the United States, and could be transferred to, stored and processed in another country outside of the EU. Please be aware that the appropriate EU government authorities have not found the United States, and possibly other countries to which your Personal Data may be transferred, to provide adequate safeguards for the protection of Personal Data. However, MSK will take steps to maintain the privacy of your Personal Data as described in this Privacy Policy. If MSK transfers your Personal Data outside the EU, we will do so in reliance on mechanisms recognized under the GDPR. This includes (i) transferring your Personal Data to countries that appropriate EU government authorities have determined to provide adequate data protection, (ii) obtaining your consent to transfer your Personal Data outside the EU after first informing you about the possible risks of such a transfer, (iii) transferring your information outside the EU if the transfer is necessary to the performance of a contract between you and MSK, including to provide treatment to you, or if the transfer is necessary to the performance of a contract between your physician or other health care provider located in the EU, and the contract was entered into in your interest, (iv) transferring your information outside the EU if necessary to establish, exercise or defend legal claims, or (v) transferring your Personal Data outside the EU to protect your vital interests.
We will retain your Personal Data for as long as is necessary for the purposes set out in this Privacy Policy (for example, if you have an account, for as long as your account is active), subject to your right, under certain circumstances, to have certain of your Personal Data erased, as discussed in the next paragraph, unless a longer period is required under applicable law or is needed to resolve disputes or protect our legal rights.
If your Personal Data is processed for GDPR Processing Activities, you have the right to (1) see Personal Data that MSK holds about you and receive any details required to be provided to you under applicable law, (2) correct or update your Personal Data, if inaccurate, (3) limit collection and use of your Personal Data under certain circumstances (for example, if you think it is inaccurate), (4) receive your Personal Data in an electronic format as required by law, except Personal Data that has been used for public interest purposes or for MSK’s required legal obligations, (5) request deletion of your Personal Data, subject to MSK’s need to keep such data to comply with legal requirements, for purposes of public health or to preserve the integrity of a research study, or to allow MSK to defend itself from legal claims, and (6) file a complaint with a data protection authority (see this link). If you have questions about the processing of your Personal Data or rights associated with your Personal Data, see the section “Contact Us” below.
- Notice to Individuals Located in the People’s Republic of China
This Privacy Policy describes ways in which you may provide information to MSK using the MSK Release of Information Requester Portal (“MSK ROI Requestor Portal”). Individuals located in the People’s Republic of China are afforded certain protections where the handling of their Personal Data is within the scope of the Personal Information Protection Law of the People’s Republic of China (the “PIPL”).
This notice applies to MSK’s processing of Personal Data that is within the scope of the PIPL, and describes how the information that you transmit to MSK via the MSK ROI Requester Portal will be used by MSK. If you travel to the United States to receive services from MSK, this notice will not apply to the Personal Data or health care information collected or generated about you at MSK. Instead, you will receive a separate notice that describes how such information will be treated by MSK under U.S. federal and state law.
In this notice, Personal Data shall have the same meaning as “Personal Information” under the PIPL. Personal Data includes information that relates to you, including but not limited to your name, address, and demographic information. Personal Data also includes “Sensitive Personal Data”, which is Personal Data that is specially protected under the PIPL. Sensitive Personal Data includes but is not limited to information about your past and present medical health, biometric characteristics, religious beliefs, specially-designated status, and your financial accounts, as well as the Personal Data of minors under the age of 14.
MSK is a Handler of your Personal Data for the purposes of the PIPL.
Description of Personal Data Handling
MSK will handle your Personal Data for the following purposes:
-
To communicate with you.
- To respond to your requests made through the MSK ROI Requestor Portal.
- To seek payment from you or a third-party (such as an insurance company or national health benefits program) making payment on your behalf.
- To comply with MSK’s statutory duties, responsibilities, and obligations, including responding to requests of regulatory agencies.
- To establish and defend against legal claims.
- To support MSK’s business and institutional interests (for example, conducting quality assurance and improvement activities and managing MSK’s business operations).
- To respond to your questions and/or your requests to exercise your rights over your Personal Data as provided by the PIPL.
In order to achieve the purpose for which MSK will handle your Personal Data, MSK will handle the following categories of Personal Data and Sensitive Personal Data:
- Basic personal information, such as your name, date of birth, gender, family relation, address, personal phone number, or email.
- Personal identity information, such as your ID number, passport, or resident certificate.
- Personal property information, such as financial information or insurance information.
- Other information, such as emergency contacts.
MSK will retain your Personal Data for the period necessary to fulfill the purposes outlined in this notice, unless a different retention period is required or permitted by law.
In order to achieve the above purposes, MSK will use various handling methods, including by collecting your Personal Data from you and others involved in your request through email, secure web forms, physical mail, and/or digital portals designed to facilitate the services. Once MSK receives your Personal Data, MSK will store your Personal Data in a data center owned by MSK, as well as in platforms owned by MSK or provided by entrusted persons designed to store and/or handle health data, such as an electronic medical record system and radiology imaging platform.
The following types of persons and entities at, or affiliated with, MSK, will handle your Personal Data in order to achieve the purposes outlined in this notice:
- Employees or contractors of MSK, such as physicians, pharmacists, nurses, administrative staff and other members of the MSK workforce, who are involved in your treatment or rendering a medical opinion to you, or who act in furtherance of MSK’s business and institutional interests.
- Contractors, vendors, collaborating entities and other entrusted persons that provide services to MSK in support of MSK’s services to you or in furtherance of MSK’s business and institutional interests.
Sensitive Personal Data
In order to fulfil the purposes of the Personal Data handling described in this notice, it will be necessary for MSK to handle the categories of your Sensitive Personal Data described in the section above. Without handling your Sensitive Personal Data, MSK would not be able to provide you with services or operate its business, as your Sensitive Personal Data is required for MSK to perform necessary actions such as providing medical records to you, seeking payment for services, or allowing you to exercise your rights provided by the PIPL.
The handling of your Sensitive Personal Data by MSK may influence your rights and interests in various ways, some of which may not be knowable by you or MSK at the time your Personal Data is handled by MSK. However, your rights and interests may be influenced as follows:
- You may receive services intended to benefit your health and well-being, including medical records retrieval, provided to you or your healthcare provider in your country.
- As Sensitive Personal Data is Personal Data that, according to the PIPL, is considered information that may cause harm to your dignity or grave harm to your personal or property security if leaked or illegally used, there is inherently a heightened risk to individuals whenever their Sensitive Personal Data is handled. However, MSK has various measures in place intended to mitigate or eliminate risks to your Sensitive Personal Data, including but not limited to: information security and access management programs and a staff data privacy training program.
Your Rights Provided in the Law
You have certain rights with respect to your Personal Data as provided in the PIPL, including as follows:
- You have the right to consult or copy Personal Data that MSK holds about you.
- You have the right request that your Personal Data be transferred to another Personal Data Handler. If you make this request, MSK will transfer your Personal Data or provide a channel through which you may transfer your Personal Data.
- You have the right to correct or update your Personal Data if it is inaccurate.
- You have the right to limit or refuse the collection and use of your Personal Data unless laws or administrative regulations stipulate otherwise.
- If information handling is based on your consent, you have the right to rescind consent.
- You have the right to request the deletion of your Personal Data. However, there are limits on your ability to request deletion of your Personal Data. For example, MSK may keep and use some or all of your Personal Data if necessary to comply with legal requirements (for example, legal and regulatory obligations related to the maintenance of medical records at MSK), or where the deletion of your Personal Data is technically hard to realize, in which case MSK shall cease handling your Personal Data except for storage and shall take necessary security protective measures.
If you have questions about the processing of your Personal Data or rights associated with your Personal Data, see the section “Contact Us” below.
Changes to this Privacy Policy
We reserve the right to amend this Privacy Policy at any time. If we make changes, we will notify you by revising the “Last Updated” date at the top of this Privacy Policy and, in some cases, we may provide you with additional notice (such as adding a statement to our homepage or sending you a notification). Therefore, please check this Privacy Policy periodically for updates and to stay informed about our information practices.
