Sections 1, 2, 3, 5, 8, 9 and 10 set out the information per category of data subjects. The numbering of the sub-sections is the same in each of these sections: sub-section .1 always concerns Patients, .2 Healthcare Professionals, .3 Verified Researchers, .4 Partner Contact Persons, .5 Supplier Contact Persons and .6 Website Visitors. For example, section 2.1 sets out which personal data we process about Patients and section 8.1 how long we keep it. The other sections apply to all categories of data subjects alike.

Definitions

In this Privacy Notice, the terms set out above and the following terms have the meaning given to them below:

Modifications

We may update this Privacy Notice from time to time to reflect changes in our data processing practices or legal obligations. The most current version of this Privacy Notice can always be found on Liberdat’s website and in the App and on the Platform. We encourage you to review this Privacy Notice regularly so that you are aware of these modifications. We will inform Patients, Healthcare Professionals and Verified Researchers of material changes via the App or the Platform.

1. Who is the controller?

Liberdat B.V., having its registered office at Soerapatistraat 59, 1018 PN Amsterdam, the Netherlands, is the controller for the processing of personal data described in this Privacy Notice, unless stated otherwise below. Other parties may also process personal data of the categories of data subjects described in this Privacy Notice. They are then responsible for their own processing.

1.1 Patients

Liberdat is the controller for the processing of Patient Data in the App and on the Platform. This includes collecting Patient Data via the App, storing it, pseudonymising and anonymising it, and making it available via the Platform to Your Healthcare Professional and to Verified Researchers (for RDRs and through Exploratory Access).

The Partner with which Your Healthcare Professional or a Verified Researcher is affiliated (for example a hospital or research institution) is a separate, independent controller for (i) Patient Data Transfers and (ii) any processing of Patient Data outside the Platform, including in the context of an RDR and in your medical file. Healthcare Professionals and Verified Researchers act under the authority of that Partner. For these activities the Partner’s own privacy notice applies and you can exercise your rights with that Partner. If you contact us about processing for which a Partner is responsible, we will tell you which Partner to contact and assist that Partner where we can.

1.2 Healthcare Professionals

Liberdat is the controller for the processing of your personal data in connection with your account and your use of the Platform. The Partner with which you are affiliated is a separate controller for its own processing of your personal data, for example as your employer, and for the Patient Data Transfers you carry out on its behalf.

1.3 Verified Researchers

Liberdat is the controller for the processing of your personal data in connection with your account, your use of the Platform and the RDRs in which you participate, including your use of Exploratory Access. The Partner with which you are affiliated is a separate controller for its own processing of your personal data, for example as your employer, and for the processing of Patient Data in the context of an RDR outside the Platform.

1.4 Partner Contact Persons

Liberdat is the controller for the processing of your personal data in connection with the collaboration between Liberdat and the Partner for which you work.

1.5 Supplier Contact Persons

Liberdat is the controller for the processing of your personal data in connection with the goods or services Liberdat obtains from the supplier for which you work.

1.6 Website Visitors

Liberdat is the controller for the processing of your personal data in connection with our website and our social media pages. For the page statistics of our social media pages, Liberdat and the operator of the social media platform concerned (e.g. LinkedIn) are joint controllers. The essence of the arrangement between us is that the operator is primarily responsible for informing you and for handling requests to exercise your rights. You can find the arrangement between Liberdat and LinkedIn here.

2. Which personal data do we process, for which purposes and on which legal basis?

For each category of data subjects, this section sets out the categories of personal data we process, the purposes for which we process it and the legal basis under the GDPR on which we rely.

Our legitimate interests

Our legitimate interests are to keep the App and the Platform secure and functioning, to prevent and investigate misuse and fraud, to analyse and improve the use of the App, and to establish, exercise or defend legal claims.

Information provided before asking for your consent

Before you consent to the use of your Patient Data for Research, we inform you in the App of the nature, purpose and duration of the research, the procedures, risks and benefits for you, how your data is kept confidential and with whom it is shared, whom you can contact with questions and how you can withdraw your consent.

Withdrawing your consent

You can withdraw your consent in the App via Settings -> Delete Account, via https://www.liberdat.io/legal/delete-account for Android users or by sending an email to privacy@liberdat.io.

You can withdraw your consent to the use of your Patient Data for an RDR in the App via Settings > Research > Research Data Requests. You can withdraw your consent to Exploratory Access in the App via Settings > Research > Exploratory Access.

If you withdraw your consent to the use of your Patient Data for Research, we will stop making your Patient Data available for new RDRs and will notify the Partners and Verified Researchers who received your Patient Data. They must then stop using it and delete it, unless the law or, to the extent permitted by applicable law, rules on scientific integrity require them to keep it, in which case it is kept in pseudonymised form for no longer than required. To the extent permitted by law, anonymised data, aggregated results, publications and trained models created before your withdrawal are not affected. If you withdraw your consent to Exploratory Access, your Patient Data will no longer be shown to Verified Researchers through Exploratory Access.

If you withdraw your consent to sharing your Patient Data with Your Healthcare Professional, they will no longer be able to view your Patient Data via the Platform. Patient Data that the Partner has already included in your medical file is governed by that Partner’s own rules.

Liberdat will inform you about this in the respective request.

Providing your account details (category a) is necessary to conclude and perform the EULA; without them we cannot create an account for you. Providing health data and consenting to its use is entirely voluntary. If you choose not to provide certain data, you may not be able to use some functionalities of the App. You are not under any statutory obligation to provide personal data to us.

3.2 Healthcare Professionals

Providing the data in categories a to d is necessary to conclude and perform the Terms of Use; without it we cannot give you access to the Platform. You are not under any statutory obligation to provide personal data to us.

When you download the App on your device, some data will automatically be transferred to the app store you selected, e.g. your username, account number, the time of the download and your device ID.

6. Do we transfer your personal data to countries outside the EEA?

Liberdat hosts the App and the Platform and stores Patient Data within the EEA. Some of our processors and recipients of personal data may, however, be established in a country outside the EEA in which applicable laws do not provide the same level of data protection as the GDPR. This may also be the case for Verified Researchers outside the EEA who access pseudonymised Patient Data via the Platform, including through Exploratory Access. In such cases, and unless permitted otherwise by applicable law, Liberdat only transfers personal data if appropriate safeguards for the protection of personal data are in place, in particular if the recipient (data importer):

If none of these transfer mechanisms are available, we may ask for your explicit consent to the transfer in accordance with Art. 49(1)(a) GDPR. Please be aware that in such countries there is a risk that your personal data will be accessed by public authorities for control and monitoring purposes, possibly without effective means of redress. Further information on the safeguards in place, including a copy of them, is available by contacting Liberdat via privacy@liberdat.io.

7. How do we secure your personal data?

This section applies to all categories of data subjects. Liberdat takes appropriate technical and organisational measures to protect personal data and to maintain at all times a level of security which, given the state of the art and the costs of implementation, is appropriate, among other things, to prevent unauthorised access, alteration, disclosure, loss or any other form of unlawful processing of personal data. These measures include:

The employees and contractors involved are bound by appropriate confidentiality obligations and must comply with our instructions aimed at the adequate protection of personal data.

8. For how long do we keep your personal data?

9. Do we use automated decision-making or profiling?

Liberdat does not make decisions based solely on automated processing, including profiling, that produce legal effects concerning any data subject or similarly significantly affect them (Article 22 GDPR).

9.1 Patients

To generate personal fitness insights and predictions, the App automatically analyses your step data together with your birth month, birth year, smoking history and gender, and predicts actual and expected trends. This is a form of profiling (Article 4(4) GDPR). The insights are for your information only, do not constitute medical advice and do not result in any decision about you. If you have consented to Exploratory Access, Verified Researchers may also configure and train Liberdat's algorithm on your pseudonymised Patient Data within the Platform. This is used only to formulate research questions and hypotheses and does not result in any decision about you.

9.2 Healthcare Professionals

The verification of your identity and eligibility involves human review. We do not use automated decision-making or profiling.

9.3 Verified Researchers

The verification of your identity and eligibility and the approval of RDRs involve human review. We do not use automated decision-making or profiling.
