We may also collect personal information through other online services you use to interact with us, such as online webinars and social media platforms, where we may be unable to directly provide a link to this Privacy Notice because the online service is owned by another party.
Some of our other products and services will contain a link to their own privacy notice, which applies in lieu of this Privacy Notice.
If you are in the United States of America, please note this Privacy Notice does not cover our use, collection, or disclosure of your Protected Health Information (“PHI”) under the Health Insurance Portability and Accountability Act (“HIPAA”). For more information about these practices, see our HIPAA Notice of Privacy Practices. If you are a California resident, please see the “Additional Information for California Consumers” section below, which sets forth additional information and rights you may have under California law relating to your information that is not HIPAA-covered PHI.
If you are in the European Union, Iceland, Liechtenstein and Norway (i.e., the "European Economic Area" or "EEA"), the United Kingdom ("UK"), Switzerland, Canada, or any other country that is not the United States, please see the “Additional Information for Users Outside the United States” section for additional information which is specific to you.
This Privacy Notice does not cover personal information that may be collected about you as an applicant for a job at Tandem or as a member of Tandem's workforce.
If you have any questions or concerns about our use of your personal information, please contact us using the contact details provided at the bottom of this Privacy Notice.
Personal information generally means information that identifies, relates to, describes, is reasonably capable of being associated with, or could reasonably be linked, directly or indirectly with you. Personal information does not include information that is de-identified or aggregated. We may combine your personal information with data we obtain from our Services, other users, or other parties. We reserve the right to convert, or permit others to convert, your personal information into deidentified, anonymized, aggregated, or pseudonymized data, as permitted by law.
What personal information we collect may differ depending on how you interact with us. For example, we collect personal information when you use our Services, such as when you use our Apps which track your insulin. This personal information may differ from personal information we collect from health care providers, clinic administrators appointed by a health care provider (collectively referred to as “HCPs”), visitors to our Websites or physical offices or individuals who contact us or voluntarily share personal information with us.
Personal information we collect about you may include:
We may collect your personal information directly from you, from other parties, or from you indirectly through cookies and other technologies, including through the following sources.
Directly from You, When You:
Additional Sources:
We may also obtain your personal information from a variety of sources, including external parties such as advertising networks, internet service providers (ISPs), contractors, data analytics providers, government entities, and social networks, as defined by applicable law.
We may collect some information automatically from your computer, mobile phone, tablet, or other device when you visit our Websites, use our Apps, use our Services or participate in Offline Activities as well as security surveillance footage when you are physically present on our premises.
In addition, we work with distributors across the world in order to provide our Services to you. Personal information will therefore be provided by you to the relevant in-country distributor when using a Tandem Service. The distributor may pass on some of this information to us if necessary, for example, to return a faulty device for investigation. Please check your relevant in-country distributor's privacy notice to find out more about the information which it will process.
We may also receive personal information from partner services when you allow external parties to provide it to us. For example, when you connect our connected devices or our Services to them, or where you choose to use a Services feature provided by an external party. We may also receive personal information about you from partners when you integrate a partner’s product with our connected devices or Services or otherwise authorize a partner service to provide personal information about you to us. Examples of such third parties include, without limitation, Dexcom, data received through Apple Health and/or Google Fit, and data received from Nightscout, Intercom, Siri Shortcuts, and iCloud.
We may also collect personal information about you from third parties who host social media webpages that we manage.
Any use of an external online service may be subject to that service’s terms and privacy policies.
Indirectly Through Cookies and Other Tracking Technologies:
We may obtain your personal information through the use of cookies and other tracking technologies. For more details, see the Cookies and Other Tracking Technologies section of this Privacy Notice.
We collect, use, disclose, or otherwise process your personal information for various purposes, including the following:
We may disclose your personal information, as described above, to:
This Privacy Notice does not apply to the practices of companies we do not own or control. Our Services may provide a link or otherwise provide access to external services. We provide these links merely for your convenience. We have no control over, do not review, and are not responsible for external services. External services and other businesses may have their own privacy policies applicable to their personal information processing.
We may use cookies, pixels, software development kits (SDKs), web beacons, mobile analytics and advertising IDs, and similar online tracking technologies (collectively “cookies” or “tracking technologies”) managed by vendors or external parties, for various reasons, such as recognizing your devices and your preferences when you log in to your Tandem account, protecting your Tandem account data, helping us improve our Services by tracking statistical information related to navigation, keeping our Services secure, troubleshooting, and generally providing a better experience on our Services.
We may use technology vendors in connection with your activity on certain pages of our Websites. The tools these vendors provide help us control how user personal information is collected by online tracking technologies. These tools also allow us to limit how certain types of Website user data, such as details about your activity on our Websites, may be transmitted to other parties.
In certain circumstances, we may combine tracking technology information with other personal information about you. We or external parties, on our behalf and pursuant to contract, may collect personal information about your online activities over time and across different online services when you use our Services.
We may use Google Analytics or other providers (such as Google Tag Manager and New Relic) for analytics services. We may also implement Google Analytics Advertising Features such as remarketing with analytics and interest-based ads. We may use first-party cookies or other first-party identifiers as well as third-party cookies or other third-party identifiers to deliver advertisements, measure your interests, and/or personalize content.
For more information on how these providers use data collected through our Services or to opt-out, visit:
You may also opt out of certain tracking technologies by visiting the opt-out services by the Digital Advertising Alliance in the U.S., the Canadian Digital Advertising Alliance in Canada, and the European Digital Advertising Alliance in the EU. You can visit Ad Choices (US), Your Ad Choices (Canada), or Your Online Choices (EU). Opting out through these services does not mean you will no longer receive advertising from us, or when you use the internet.
Depending on your device settings, you may also opt out of certain interest-based advertising through the device’s "Limit Ad Tracking" or equivalent feature. Refer to your device for more information on what this opt out affects. For instance, you can generally adjust or reset the advertising identifiers on your mobile device in the device settings. In addition, iOS and Android operating systems provide options to limit tracking and/or reset advertising IDs.
You can set your browser to refuse cookies from websites, but if you do so, you may not be able to access or use portions of our Services, and certain offerings on our Services may not function as intended or as well.
To control web beacons, most email providers have settings which allow you prevent the automatic downloading of images, which will disable web beacons in the email messages you read.
We are not responsible for opt-out processes provided by external parties.
We may engage vendors to provide certain interactive features on our Services. Your use of these interactive features is voluntary, and we may retain the information that you submit through these features. For example, we may offer an interactive chat or voice assistance features on our Services to answer questions and for other customer service purposes. When you participate in the interactive features, either with a virtual or live agent, the contents of the communication may be captured and kept as a transcript. By using these features, you understand that our vendors may process the information obtained through the feature to provide the service on our behalf.
We use appropriate administrative, technical, physical, and organizational measures to protect the personal information we collect and process about you. The measures we use are designed to provide a level of security appropriate to the risk of processing your personal information. While we implement security measures designed to be appropriate to the relevant risks, please note no data transmission over the internet or any wireless network can be guaranteed as 100% secure.
We will store your personal information for no longer than is necessary for the performance of our obligations or to achieve the purposes for which the information was collected, or as may be required or permitted under applicable law. To determine the appropriate retention period, we will consider the amount, nature, and sensitivity of the data; the potential risk of harm from unauthorized use or disclosure of the data; the purposes for which we process the data and whether we can achieve those purposes through other means; and the applicable legal requirements.
Some of our Services may have settings available to you to allow you to set preferences. Information collected through our various Services, such as between our online portals and Apps, may not be synchronized (especially when you are not logged into one Service, and you are logged into another). Where information is not synchronized and you would like to have consistent settings, you may make sure your settings across Services are consistent by accessing each Service independently, and you may contact customer service if you have any issues.
Some of our Websites provide you with the opportunity to manage your cookie and tracking technology settings. To opt out of the use of certain tracking technologies, please click on the “Do Not Sell or Share my Personal Information” link in the footer of the Website you are visiting.
If you receive marketing emails from us, you may opt out through the email’s instructions, as provided. Please note that regardless of your email preferences, we may send you notifications pertaining to the performance of our Services, such as revision of our Terms of Use or this Privacy Notice or other formal communications relating to Services you have purchased or used. If you receive texts from us, you may opt out by texting “STOP” to the number contacting you.
Parts of our Services may be available and/or directed to children. Where required by law, we seek to obtain the verifiable parental consent from the child’s parent or guardian. Where the law requires us to obtain verifiable parental consent and we learn that a child, as defined under that legal requirement, has provided us personal information independently without the permission of their parent or guardian, we delete that information.
This Section is provided pursuant to the California Consumer Privacy Act, as amended (the “CCPA”) and describes how Tandem may collect, use, and disclose personal information of consumers that reside in California. Please note certain information we collect, use, and disclose is considered PHI, as described above, and is therefore covered by our HIPAA Notice of Privacy Practices.

If you are located in certain countries, subject to certain conditions, you may ask us to take the following actions in relation to your personal information:
You may designate someone to act on your behalf, for example, if you have given someone power of attorney or if someone is your legal guardian.

Legal Bases of Processing
For users located in jurisdictions that require certain bases for processing personal information, including the EEA and the UK, our processing of your personal information is carried out under the following legal bases:
Given the nature of our business, we may process special categories of your personal information in the form of health information. This information includes diabetes therapy data, such as your glucose levels, biometrics, related exercise and eating habits, and lab charts. We will only process this information in accordance with applicable law such as obtaining your explicit consent or where processing is necessary for reasons of public interest in the area of public health.
Transfers of Personal Information for Data Subjects located in the EEA, UK, and Switzerland
Where we transfer your personal information to countries and territories outside of the EEA, the UK and Switzerland, which have been formally recognized as providing an adequate level of protection for personal information, we rely on the relevant “adequacy decisions” from the European Commission, “adequacy regulations” from the Secretary of State in the UK, and the adequacy assessment from the Swiss Federal Council, as applicable (together referred to as "EEA/UK/Swiss adequacy decisions").
Some EEA /UK/Swiss adequacy decisions require Tandem to take steps in order for relevant transfers to be covered, in particular for transfers to the U.S. under the EU-U.S. Data Privacy Framework ("EU-U.S. DPF"), the UK Extension to the EU-U.S. DPF ("UK Extension"), and the Swiss-U.S. Data Privacy Framework ("Swiss-U.S. DPF") as set forth by the U.S. Department of Commerce.
Tandem Diabetes Care, Inc. has certified to the U.S. Department of Commerce that they adhere to:
To learn more about the Data Privacy Framework ("DPF") and to view our certification, see here. It is important however for us to provide you with the following information about our certification:
Where the transfer is not subject to an adequacy decision or regulations, we take appropriate safeguards to require your personal information will remain protected. The safeguards we use under GDPR, include the European Commission’s Standard Contractual Clauses ("SCCs") as issued on 4 June 2021, in the form of modules 1 (controller to controller), module 2 (controller to processor), module 3 (processor to processor) and/or module 4 (processor to controller), as appropriate depending on our relationship with the recipient(s). We incorporate the UK's International Data Transfer Addendum to the EU Commission SCCs as permitted under Article 46 of the UK GDPR, when transferring personal information protected under UK GDPR and the Swiss Addendum to the SCCs as provided by the FDPIC in its statement of 27 August 2021.
Our SCCs can be provided on request. Please note some sensitive commercial information may be redacted. For details of what personal information may be transferred to group entities or third parties, please see the Disclosing Your Information section of this Privacy Notice above.
In exceptional circumstances, personal information may also be transferred to countries that are not subject to an adequacy decision or regulations on the basis of a derogation. A derogation may apply, for example, in case of legal proceedings abroad, if transfer is necessary for the performance of a contract, if you have consented to the transfer, or if the data has been made generally available by you and you have not objected to the processing.
We may update this Privacy Notice from time to time. You can see when this Privacy Notice was last updated by checking the “Last Updated” date displayed at the top of this Privacy Notice. Any changes to this Privacy Notice take effect immediately after being posted or otherwise provided by Tandem.
