Please note that some of the above-mentioned third parties can be located outside your country. Therefore, your personal data may be transferred to countries that do not provide the same level of protection of personal data as your own country. In such cases, we undertake to:

  • implement adequate procedures to comply with applicable law;
  • adopt appropriate organizational, technical and legal safeguards in order to ensure an adequate level of protection of the personal data transferred;
  • implement, if necessary, and according to applicable law, standard contractual clauses as adopted by the European Commission and/or the relevant supervisory authority;
  • depending on the country of the importing third party, take additional measures such as conducting a transfer impact assessment.

Sonova AG will retain your personal data for a minimal period proportional to the time required to fulfil the purposes outlined in Section 2. This is the case for personal data processed based on the performance of the contract. In the event applicable law or other regulations require a longer retention period, we will apply the longer retention period in order to fulfill our legal obligations.

For personal data processed based on your consent:

  • Insights: if you decide to deactivate the processing all personal data will be deleted.
  • Google Firebase - Analytics: it is not possible to identify you with data collected for this processing, for any further questions please refer to their retention policy.


All other data submitted by you  (ratings, questionnaire, usage, etc.) are deleted after 7 years if they are no longer required for the purposes.

Your personal data processed by HCPs, such as for Asynchronous distance support processing, will be retained according to HCPs policy and applicable laws. For more information on their specific retention periods, please contact your HCP.

Within the framework of the collection and processing of your personal data, and as per applicable law, you may have the right to request access, rectification, erasure of your personal data, or restriction of processing. In addition, you may object to the processing, request data portability and withdraw your consent at any time. According to your country, you may have other rights such as providing instructions for how your personal data should be processed posthumously. Under HIPAA you may also have the right to request an accounting of disclosures of your personal data, and the right to receive a paper copy of the notice of privacy practices upon written request.

You may exercise your rights by using the contact details in the “How to contact us” Section below, or you should contact your HCP if your rights concern personal data processed for the purpose of Remote Support Service.

If you consider that the processing of your personal data infringes applicable law then you may also lodge a complaint with the local supervisory authority or the competent regulator. 

The Mobile App may contain links to other websites or content belonging to or originating from third parties or links to websites and features in banners or other advertising. Such external links are not investigated, monitored, or checked for accuracy, adequacy, validity, reliability, availability or completeness by Sonova. Therefore, please note that the Mobile App does not disclose any personal data to those third parties and their websites and that we are not responsible in any way of personal data processed by them.

For example, this is the case with the Works with Unitron screen which gives you access to a list of 3rd party lifestyle and wellness-oriented applications that are therefore not under Sonova’s responsibility.
