Declaration of Consent for Data Protection Regarding the Preventicus Heartbeats App

By declaring my consent with the processing of my health data, I agree to the data processing connected with the use of the PREVENTICUS Heartbeats app in accordance with the applicable privacy policy and the terms and conditions of use.

If I use the medical engineering service of the Telecare Centre, I also declare my consent with the necessary processing of my health data this entails in accordance with the applicable privacy policy and T&Cs of the Telecare Centre.


I may revoke my consent for the future at any time. However, the revocation of my consent does mean that contractual use of the PREVENTICUS Heartbeats app or Telecare Centre is no longer possible. Processing on a statutory basis cannot be ruled out either if consent is revoked.




This privacy policy is intended to inform you on what basis and for what purposes we process the personal data we collect from you or you provide us with when you use the PREVENTICUS Heartbeats app. We would also like to tell you more about your data protection rights.

Additional data protection regulations may apply for certain categories of data processing, e.g. if you are using the PREVENTICUS Heartbeats app to take part in a study or a telemedical care programme of your health insurance.


The PREVENTICUS Heartbeats app is a medical product classified for the European Economic Area, which complies with the basic requirements of Guideline 93/42/EEC and its national implementations.


For more information, please refer to the Terms and Conditions of Use.

PREVENTICUS will process your personal data confidentially and strictly for specific purposes. Your health data will exclusively be processed on servers in Germany.


  1. Who is responsible for data processing and who should I contact?
    Responsible in terms of the General Data Protection Regulation (GDPR) is:

Preventicus GmbH
Ernst-Abbe-Str. 15
07743 Jena

You can contact our Data Protection Officer by means of the above contact details or by email at

  1. What are personal data?
    Personal data is information that can identify someone or that can be used to contact someone, such as an e-mail address.


We do not need your name or any other contact details from you for you to use the PREVENTICUS Heartbeats app, but we save your data without a name reference (pseudonymised) on our systems from the start.


The PREVENTICUS Heartbeats app is therefore not used to process any personal data that can be directly attributed to you. PREVENTICUS cannot identify or individually contact any unregistered users based on the data generally saved in PREVENTICUS Heartbeats.



III. What kind of data do we collect?

III.a Health data
You can use the PREVENTICUS Heartbeats app to take measurements of your own pulse using your smartphone and document them with the app. The PREVENTICUS Heartbeats app then uses the information provided to help automatically detect and classify arrhythmias (extrasystoles, atrial fibrillation), provided sufficiently accurate and valid measurements are available (“health data”). Your heart rhythm and pulse waves will be stored on our servers.

III.b Sensor data
In addition to the classification of the measurements, not only your smartphone’s camera but also other sensor data are used for and added to the measurements. This is done to ensure that any movements that could impair the measurement result are taken into account.


As a result of your registration, your licence can be transferred regardless of the operating system you are using and your measurement data can be reproduced if you change or lose your smartphone. It also enables you to take part in a care programme or medical study.


III.c Other data you communicate to us

We generally require neither your name nor any other personal contact data from you, but save your data initially without a name reference (anonymously) on our systems. Processing takes place solely on servers in Germany.

You do, however, have the possibility to add your name and, in a free-text field, store the reason for the measurement or symptoms (heart palpitations, dizziness, irregular heartbeat, chest pains, etc.) for personal purposes in stored PDF reports, for instance to be used for assistance when forwarding the information to your physician. In your user profile you can also state your sex and year of birth, thus enabling us to better assess your measurement results.

III.d Registration

If you would like to register with us, please communicate your e-mail address and a password set by you. Optionally, you can assign a user name, state your name and enter a promotional code in the field ‘ID health partner’.

Your data will then be saved in a pseudonymised manner. This means that your personal data is stored in encrypted form in a separate database from your health data and can be assigned if necessary. Processing takes place solely on servers in Germany.

Registration enables the transfer of your licence irrespective of the operating system and the recovery of your measurement data, should you change or lose your smartphone.


III.e Interoperability option
PREVENTICUS Heartbeats may be opened and used for heart rhythm measurements by dedicated medical applications. In this case, PREVENTICUS Heartbeats performs its measurements with subsequent pseudonymized data analysis on servers hosted in Germany. The pseudonymized results are securely transferred back to the dedicated medical applications. In this scenario, PREVENTICUS Heartbeats does not receive any personal data from the dedicated medical applications except being necessary for data analysis (age and gender). Only the dedicated medical applications connected to PREVENTICUS Heartbeats may be able to merge pseudonymized measurement results from PREVENTICUS Heartbeats with potentially personal user data derived in the dedicated medical applications. PREVENTICUS Heartbeats is an independent medical application. When using the interoperability option, please refer to the privacy notices of the third-party compatible medical app you are using.

PREVENTICUS has no influence on any further processing of your measurement results in these third-party medical applications.

List of dedicated medical applications being interoperable with PREVENTICUS Heartbeats:

  • mAFA. Mobile Health Technology for Atrial Fibrillation Management Integrating Decision Support, Education, and Patient Involvement: mAF App Trial
  • MAFA and its connected application is scientific project in China mainland led by Prof. GUO YUTAO (301 hospital Beijing, PRC).
  • UKSH App: Health Hub (IBM Project Electronic Health Record)


III.f. General data we collect regarding the use of our app

III.f.1. Firebase
Heartbeats uses Google Analytics for Firebase and Firebase Crashlytics services based on your consent. We use these services to collect statistically aggregated data on app usage, especially in relation to system crashes and errors (Firebase Crashlytics) for error detection and correction, as well as certain user-triggered events (Google Analytics for Firebase) for the optimisation of our app. Please note that Google may also transfer data to the USA. With your consent, you also agree to such transfers in accordance with Art. 49 (1) sentence 1 lit. a DSGVO. In particular, there is a risk that your usage data may be processed by US authorities for control and monitoring purposes, possibly without any legal remedy. We have entered into a data protection agreement with Google LLC, including so-called standard contractual clauses. These are intended to guarantee an adequate level of data protection for data subjects affected by processing in insecure third countries, in particular legally binding and enforceable rights. For more information, including to request a copy of the documents used to protect your data, please contact us.


For Crashlytics, information is collected about the device (including the UUID and anonymised IP address), the app version installed, and other information, mainly related to the user’s software and hardware. For Analytics, when the user performs a certain action, an identifier corresponding to the event, the instance ID of your terminal device, is sent to Google. The usage and device data is aggregated and analysed exclusively in pseudonymised form by Google LLC as our order processor. Your data will not be passed on to third parties.


You can deactivate the analysis service Firebase Crashlytics and Firebase Analytics of Google LLC at any time and thus revoke your consent to the collection of this data with effect for the future. To do so, open the settings (cogwheel in the top right-hand corner) and click on “Deactivate”.


Insofar as you participate in a care programme used via Heartbeats that your health insurance company jointly organises with us, among others, the data collection Firebase Crashlytics and Google Analytics for Firebase will be deactivated by us at the start of the contract of the respective care programme and reactivated after termination.

Furthermore, the Firebase Cloud Messaging service by Google Inc. will be used for the Android app, as well as the Apple Push Notifications service for the iOS app to send push notifications or so called in app messages (messages that are exclusively being shown inside the app) to your device. During this process Firebase and Apple are generating a calculated key, that consists of the app identifier and your device identifier. This key will be stored on our Push platform with configured settings to provide you with the information of your choosing. The Firebase or Apple server cannot draw any conclusions regarding the users app behavior or collect any other data that is associated with your person. Firebase and Apple are only utilized as a message transmitter.

Push notifications can be disabled in your devices operating system settings at any time. We are not processing any personal data in relation to push notifications.

III.f.3. Scientific research purposes

For scientific research purposes, we process the IP address for the anonymous classification of your residential district, as well as further statistical data, such as age and gender.

  1. Data processing for payment processing when using the full version
    If you would like to use the full version, your app store operator will exclusively process your payment details for handling your purchase. Your contact and payment data is not communicated to us. Please observe the data protection provisions and user regulations of your respective app store operator, Apple App Store and Google Play Store.
  2. Where do we store your personal data?
    By using this app, in accordance with your consent to the use of Google Analytics for Firebase and Firebase Crashlytics, data will be transferred to countries outside the European Economic Area (“EEA”). For those countries exists no adequacy agreement with the European Union, because in those countries are no comparable data protection regulations (so called third countries). All other data is processed exclusively in data centres in Germany.
