Notes on data collection and processing

Your personal data will be processed according to the instructions we provide to our employees who have received the necessary training in data protection and are subject to an obligation of confidentiality.

Your personal data may also be disclosed to:

  • Other companies in our group of companies, such as our subsidiaries, all of which are required to protect personal data in accordance with applicable privacy and data protection laws;
  • Our business partners, contractors and third-party service providers. These third parties only process personal data that are strictly necessary for the services they provide to us, according to our instructions and in compliance with our privacy and security requirements.

Before we disclose any personal data to other third parties than those listed above, we will explicitly ask you for your consent. However, if we are obliged to disclose personal data without your consent, we will only disclose personal data that are strictly necessary for that purpose to fulfil our legal obligations.

The following information is required to establish a connection to a Sennheiser product: Bluetooth address (for Android), access rights to location information of the device (for Android), BLE UUID (for iOS). This data is required for the operation of the product on your device and is not transferred to us or companies commissioned by us and is not processed.

The use of the app on Android devices mandatorily requires the activation of location services to enable the functioning of the app and the operation of a Sennheiser product. The connection to your Sennheiser product is established using Bluetooth Low Energy Scan (BLE Scan) technology, which requires access to the location services of your device. If you do not enable location services, the app cannot connect to your Sennheiser product. Sennheiser does not process location information for any other purpose.

Microphone access is required to detect if the test conditions are ideal. The access is mandatory and can be manually revoked if needed, once accepted. This data is only used for the purpose of determining the level of background noise before and during the hearing test and is not transferred to us or companies commissioned by us and is not processed. The hearing test can be completed without microphone access.

Installation and use:

Sonova Consumer Hearing GmbH does not transfer any personal data to any third parties.

Certain usage data and crash reports are processed using Google Firebase (a service of Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland), subject to your consent. Such processing is necessary to provide a continuously improved app and is only done in anonymous form to determine statistical characteristics regarding app usage, app distribution and identification of error causes, as well as for the purpose of providing and maintaining the app and improving the features of the app. At no time can a reference be made to a specific person. In particular, the following information is processed:

  • Frequency, type, and duration of app use
  • Type of device used with the app
  • Operating system and version number
  • Error reports in case of app crash

The Google Firebase Analytics and Crashlytics services used by the app automatically collect anonymized data. A complete overview of all possible collectable events can be viewed via the following link: The events relevant to our app are limited only to the first chapter ‘Automatically collected events’, whereby in particular all mentioned events in connection with advertising (ads), in-app purchases (in-app buy), subscriptions (subscriptions) are not relevant as these functions are not supported by the app.

If Google Firebase transfers your data to third countries outside the European Economic Area (“EEA”), the standard data protection clauses issued by the European Commission apply in conjunction with appropriate technical and organizational safeguards.

By selecting the appropriate setting in the “Permissions” section of the app menu, you can consent to the processing of your anonymized data by Google Firebase or prevent it at any time by revoking your consent with future effect.

If you log in to the Hearing Test app using your SCH user account or create a user account in the app, the following data is processed automatically to provide you with personalized settings and features (Art. 6 para. 1 lit. b GDPR):

This data is stored to ensure the functionality of the features on multiple devices and after reinstallation. You can remove the data in the app at any time, but then you will no longer be able to access the data from this and other devices and benefit from viewing your test history.

Deleting your user account will also delete all associated profiles and settings from our systems.

We use Microsoft Azure (provider: Microsoft Corporation, One Microsoft Way, Redmond, WA 98052-6399, USA) to store data associated with the user account. In order to maintain the level of data protection granted by the European General Data Protection Regulation (GDPR), Sennheiser has concluded the standard data protection clauses or “standard contractual clauses” issued by the European Commission in conjunction with appropriate technical and organizational safeguards with the provider. If your country of origin entered during registration belongs to the European Economic Area (“EEA”), your data will be stored in data centers within the EEA. For users from other regions, data center locations will be determined in accordance with relevant data localization requirements.
