Privacy Policy

June 14, 2018

Threema GmbH (hereafter “Threema”) was founded on the premise of bulletproof data protection. It is our primary goal to store only the absolute  minimum of information for the shortest possible time (“Privacy by Design”). In addition to using state-of-the-art encryption methods, we take all necessary technical and organizational measures to prevent unauthorized data access and misuse. The processing and protection of data is carried out in accordance with applicable legal regulations and EU Regulation 2016/679 (GDPR).

By using the “Threema Broadcast” website, you consent to the collection, processing and use of data as described below.

1. General Information

This Privacy Policy refers to the processing of personal data in connection with the use of Threema Broadcast (hereinafter “Service”) on behalf of the customer (hereinafter “Customer”). The Service enables the customer to communicate with users of the Threema and Threema Work apps, to provide them with interactive communication tools, and to control and manage the use and users of the Service. In order to use the Service, the Customer must create one or more accounts on the Service's website.

2. Purpose of Data Processing

Threema processes personal data to enable the Customer to access the web administration interface of the service and to process orders. The data processed within the scope of order fulfillment will be processed exclusively by Threema on its own server infrastructure in Switzerland and will not be passed on to third parties.

Threema does not process special categories of personal data as defined by Art. 9 (1) or Art. 10 GDPR. Based on Art. 5 (1) GDPR, personal data is processed solely as a result of self-declaration and only to the extent required for the Use of the Service.

Except for the legally required data storage for business transactions, inventory data is only stored until it is deleted by the Customer or the Customer deletes all accounts.

  1. Threema IDs of recipients added by the Customer and all subscribers of Customer's feeds
    1. Optional, if entered by the Customer: Recipient's first name, last name and language

Should this option be used, the Customer is obliged to comply with the relevant legal provisions and to inform it users of this fact.

Personal data arising from the use of the Service will only be stored until deleted by the Customer or until the Customer deletes all of his accounts. Deleted data will not be archived and cannot be restored.

Its use is subject to the data protection declaration of the reCaptcha provider Google Inc. The IP address transmitted by the Customer’s browser while using reCaptcha is not merged with other Google data. For more information about Google’s Privacy Policy, please visit
