Notes on data collection and processing and on firmware updates

The following information is required to establish a connection to a device: 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 your 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.

Using the “Sennheiser Smart Control” app, you can update the product’s firmware free of charge via an Internet connection.

It is possible to register for push notifications (optional opt-in) in the event of newly provided firmware of a Sennheiser product connected to the app. If this function is used, then a PNS handle (Platform Notification Service) corresponding to the operating system (Android or iOS) is installed on the device. This PNS handle does not contain any personal data. This setting can be revoked at any time.

Updating the firmware requires your consent. If the device on which the app is installed is connected to the Internet, the following data is transferred to our servers and processed there in order to provide and transfer appropriate firmware updates: hardware identifier, hardware revision number, firmware version of the product, operating system type (Android, iOS) and version, version of the app. The data is only used for the purpose of providing and transferring firmware updates (legal basis Art. 6 para. 1 lit. b GDPR) and is not stored permanently.

If you do not want this data to be transferred and processed, do not establish an Internet connection.

Installation and use:

Sonova Consumer Hearing GmbH as the publisher of the app itself does not collect or process any personal usage data. Therefore, there is also no transfer of personal data by Sonova Consumer Hearing GmbH to 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
  • Settings made on the device such as equalizer, Active Noise Cancellation (ANC) mode or other device-specific settings.
  • Type of device used with the app
  • Operating system and version number
  • Number of firmware updates performed
  • Error reports in case of app crash

supplementary only when used with products of the Sennheiser wireless Bluetooth headset series:

  • Operating time, number of usage cycles
  • Duration of use of the various ANC programs and number of switchovers
  • Accumulated charging time and number of charging cycle
  • Total duration in phone mode and number of times it was switched to phone mode
  • Accumulated connection time of two devices and number of connections of an additional device
  • Duration of audio playback and number of times playback was started
  • Crashes

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 “Privacy” 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.

Personalized data in case of User Registration (Sennheiser account)

If you log in to the Smart Control 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):

• user-created profiles and settings such as: EQ presets, sound zones & sound personalization profile

This data is stored to ensure the functionality of the features on multiple devices and after reinstallation. You can prevent the storage of this data in the app settings at any time, but then you will no longer be able to access the data from other devices and benefit from personalized settings. In this case, your personalized profiles and settings remain stored only locally on your device and are not accessible to us. The data stored locally on the device will be deleted when you delete or uninstall the app.

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.

  • product feedback (self-reported by the user)

Using MOMENTUM Sport devices

If you use MOMENTUM Sport devices with the app, please note that those are equipped with sensors that allow your heart rate measurement and core body temperature to be displayed in the app. The app can only show those data: those are not stored in the app, and cannot be assigned to you, even if you are logged in to your account.
