Updates To The Website Privacy Policy
Any changes to the WPP will be posted on this Website promptly. Your continued use of the Website constitutes your agreement to this WPP.

Patient Notice
iRhythm Technologies Ltd. and iRhythm Technologies, Inc. ("iRhythm™"), care about your confidentiality and privacy rights and comply with data protection laws to keep your information safe. Please read this patient notice carefully.

Confidentiality and consent

Your doctor has prescribed the Zio service for you. iRhythm provides the Zio service, which includes long-term heart monitoring and evaluation. Your doctor will, with your consent, start the Zio service by attaching an adhesive monitoring device to your chest. This device will collect your heart rhythm data. Your doctor will collect identification information such as your name, address and date of birth, and send it to iRhythm. Your heart rhythm data will be sent to iRhythm when you return the Zio patch by post.

iRhythm receives and processes your personal data in confidence to help create a report of the findings. Only iRhythm, your doctor and hospital will have access to this report for the purpose of supporting your direct care. iRhythm may also replace your direct identifying information with a reference number and study your heart rhythm data for two reasons: (i) reporting to your doctor and (ii) improvement of iRhythm services.

You have the right to object to the disclosure of your personal data. If you wish to do so, please contact the iRhythm Privacy Official through our UK office at 0-808-189-3411 or via email at Please also consult your doctor regarding his or her privacy practices.

Data Protection

Here we explain how iRhythm collects and uses your personal data and heart rhythm data during and after your use of the Zio service.

How will iRhythm use information it receives about you?

iRhythm will use your personal data for the purpose of providing preventive medicine services, supporting medical diagnosis and the provision of direct health care or treatment by your doctor and/or hospital.

iRhythm may also use your personal data in the following situations:

  • To conduct analysis in iRhythm's legitimate interests for statistical reporting purposes;
  • To improve iRhythm services, after ensuring your interests and rights do not override;
  • In the event iRhythm needs to comply with a legal obligation; or
  • Where it is needed to protect your vital interests (or the interests of another person).

Your personal data will be used only for the purposes set out in this patient notice. If iRhythm needs to use your personal data for an unrelated purpose, we will notify you and where relevant obtain your consent.

Data sharing

We may share your information in the following circumstances:
  • Within the iRhythm Group when needed to support our processing of your personal data.
  • iRhythm may provide personal data to third parties including our vendors, partners and service providers (e.g. cloud service providers) who perform services on our behalf. These providers have limited access to your personal data only to the extent necessary to perform these support tasks on our behalf and subject to the same confidentiality and security safeguards as those applied by iRhythm.

We are responsible and remain liable for the processing of personal data we receive, under the Privacy Shield Framework, including if we subsequently transfer to a third party acting as an agent on our behalf. We comply with the Privacy Shield Principles for all onward transfers of personal data from the EU, including the onward transfer liability provisions. In certain situations, we may be required to disclose personal data in response to lawful requests by public authorities, including to meet national security or law enforcement requirements. By returning the Zio patch to us, you acknowledge that you have read and understood this patient notice (as contained in the Zio booklet). It is important to note that the Zio booklet contains a similar separate notice which is provided physically to you. It includes an invitation for you to sign a declaration confirming your agreement to use the Zio patch and that is then sent back by you to iRhythm for the purposes set out in this patient notice.

International Data Transfers

In accordance with European Union data protection law, iRhythm will transfer your personal data to its clinical center(s) and systems in the United States. iRhythm participates in and complies with the EU-US Privacy Shield, as set forth by the U.S. Department of Commerce regarding the collection, use, and retention of personal data transferred from the European Union to the United States.

Please see for more information about our certification. Our privacy shield notice is available at

Although the Court of Justice of the European Union (CJEU) ruled in July 2020 that the EU-US Privacy Shield is no longer a valid mechanism for transfers of personal data from the European Union (EU) to the U.S., the same ruling, however, confirmed that SCCs remain a valid legal mechanism to transfer personal data outside the EU. iRhythm’s use of SCCs as described above is intended to comply with this ruling.

How long will your information be used for?

We retain personal data for the length of your use of the Zio service and as necessary to meet our contractual obligations, to identify issues or to resolve legal proceedings. We may also retain aggregate information beyond this time for research purposes and to help us develop and improve our services. You cannot be identified from aggregate information retained or used for these purposes.

Your rights in connection with personal data, including access:

You have the right under certain circumstances:
  • To be provided with a copy of your personal data held by us;
  • To request the rectification or erasure of your personal data held by us;
  • To request that we restrict the processing of your personal data (while we verify or investigate your concerns with this information, for example);
  • To object to the further processing of your personal data; and
  • To request that your provided personal data be moved to a third party.

Where the processing of your personal data by us is based on consent, you have the right to withdraw that consent by contacting us, your doctor or hospital. The possible consequences of this will be explained to you and could include delays in diagnosis, care or treatment that the Zio service supports.

Within the scope of our authorization to do so, and in accordance with our commitments under the Privacy Shield, we will use commercially reasonable efforts to work with our business partners, such as our Business Associates, to provide individuals access to personal data about them that they may hold on our behalf. We will also take commercially reasonable steps to enable individuals, either directly or in connection with our business partners, to correct, amend, or delete personal data that is demonstrated to be inaccurate.

You may have the right to access personal data that we hold about you and request that we correct, amend, delete it if it is inaccurate or processed in violation of Privacy Shield.
