cosinuss° takes the protection of your personal data very seriously. We only collect and store data that is necessary for the purpose of the products and services described here. We treat collected data confidentially and in accordance with the statutory data protection regulations.
This privacy policy applies to the iPhone and Android corpuls auryx Apps (hereinafter called “app” or “corpuls auryx App”), which can be used in combination with the c-med° alpha and the corpuls auryx in-ear vital signs sensors (hereinafter called “sensor”).
The c-med° alpha is an ear-worn class IIa medical device that continuously monitors vital signs inside the outer ear canal. It collects human biosignals, calculates vital signs and transmits the values in real time to the corpuls auryx App.
The corpuls auryx is an ear-worn class IIb medical device that continuously monitors vital signs inside the outer ear canal and can be used on critical patients in emergency settings. It collects human biosignals, calculates vital signs and transmits the values in real time to the corpuls auryx App.
This declaration explains the type, purpose and scope of data collection in the context of app use.
What data is collected when using c-med° alpha/corpuls auryx
with the corpuls auryx App?
The c-med° alpha/corpuls auryx in-ear sensors generate and send data to the corpuls auryx App via Bluetooth Low Energy, but do not store any data themselves. If there is no Bluetooth connection for a short time, the vital parameter data recorded and calculated by the sensor will be lost at that time. The app displays and saves the received data and allows you to export and share it.
A measurement can be stopped at any time by exiting the corpuls auryx app or turning off the sensor.
The following data is generated when using c-med° alpha/corpuls auryx with the corpuls auryx App:

Data Protection Impact Assessment (DPIA)
A Data Protection Impact Assessment (DPIA) is required under the GDPR any time you begin a new project that is likely to involve “a high risk” to other people’s personal information. With Remote Vital sign monitoring this may be the case if the type of processing in particular is:
- Using new technologies
- Tracking people‘s behaviour
- Processing data concerning health
- Processing used for automatic decisions
- Processing children‘s data
cosinuss° recommends preparing for a DPIA before beginning any data processing activity. Ideally, the DPIA should be conducted before and during the planning stages of a new project. If you have a Data Protection Officer you must consult with that person, and any other key stakeholders involved in the project, throughout the course of the DPIA. It should contain the following elements:
- A systematic description of the envisaged processing operations and the purposes of the processing, including, where applicable, the legitimate interest pursued by the controller.
- An assessment of the necessity and proportionality of the processing operations in relation to the purposes.
- An assessment of the risks to the rights and freedoms of data subjects.
Data collected on the basis of granted access rights
Location data & Bluetooth
In order for you to connect your c-med° alpha to your receiving device via Bluetooth Low Energy, your operating system (usually the case with Android) will require access to your location data. The °Health App and Cosinuss GmbH have no influence on this access and do not obtain access to your location data.
Cosinuss GmbH also points out that data transmission via Bluetooth involves security risks. Complete protection of data against access by third parties is not possible.
Error analysis
Upon your optional consent, in case of a technical error, you may authorize a technical event log (log file) to be sent to Firebase Crashlytics for a specific error event. The log file is also provided to cosinuss° and helps the development team to know about errors and to find and fix the cause of them. In the log file, device information of the c-med° alpha and your mobile device, °Health App version information and settings of your operating system at the time of the error are sent along. Recorded vital signs will be explicitly not sent along. Firebase Crashlytics is operated by Google. The respective privacy policies can be found at https://privacy.google.com/ and https://firebase.google.com/support/privacy/. Submitted data may be retained in Firebase’s processing systems for an extended period of time.
When logging errors, cosinuss° explicitly only uses the Crashlytics and no other Firebase services.
Location of the cosinuss° servers
The cosinuss° servers are provided and hosted by Hetzner Online GmbH, located at Industriestrasse 25, 91710 Gunzenhausen. A corresponding data processing agreement exists between the parties. The servers are located in Nuremberg and Falkenstein (Vogtl.) in Germany. Hetzner Online GmbH is DIN ISO/IEC 27001 certified and thus offers the legally required protection for personal data.
