Information collected when downloading TB Companion from the app store

When downloading TB Companion from your selected app store, various data such as username, e-mail etc. are sent. The processing of this data is carried out exclusively by the respective app store and is not subject to our influence.

Collection, processing and use of personal information

When using TB Companion, you decide which personal information you provide to us, so the information is always provided on a voluntary basis. Personal information is processed when you enter it in our system. In addition to general personal information, specific personal information about your health/illness is also requested (hereinafter referred to as health-related information). When opening the app for the first time, you will be asked to confirm the privacy policy. Please read it thoroughly before accepting it. If you do not provide any information, only the anonymous storage of your access data will take place, i.e. the time of access, the operating system used and (if separately agreed) the location data via GPS. The IP address is known at the time of encrypted data transmission, but it’s not stored. The legal basis for the processing of the data is Art. 6 para. 1 DS-GVO. You can revoke your consent to the processing of your data at any time with us. In the event of a revocation or if you do not give consent, no data will be stored, but the app will not be functional.

If you provide personal information to us, they will be processed exclusively for the following purposes:

Data security

The SSL/TLS (Secure Sockets Layer/ Transport Layer Security) encryption system ensures that all data in this app is transferred in encrypted form and protected against unauthorized access. The client establishes a connection to the server, which authenticates itself to the client with a certificate. The client checks the trustworthiness of the X.509 certificate and whether the server name matches the certificate. The client then sends the server a secret code encrypted with the server's public key, from which a cryptographic key is derived. This key is subsequently used to encrypt all messages in the connection using a symmetric encryption scheme and secured by a Message Authentication Code to protect message integrity and authenticity. All transferred information is stored on servers in Germany at GE-MU Systems (Neumünstersche Straße 26, 20251 Hamburg, Germany). This company ensures that the processing of personal data is technically secured according to current standards.

Data management and storage and possibility of deletion

The app communicates with the server via the Internet exclusively in encrypted form. This means that all information exchanged between the app and the central database cannot be read by third parties. The connection is made via SSL/TLS (ISO/IEC 20648) standard (see 10.2. Data security). Personal information is only collected and stored anonymously after users have explicitly agreed to all data protection provisions. All personal data is encrypted in a so-called crypto container on the user's end device and can only be used by the app designated for this purpose. When the app is uninstalled (on both iOS and Android systems), this data is irrevocably deleted. If a user has already synchronized personal information with the central database after consent, he has the option to delete his data at any time and without restriction in accordance with Art. 17 DSGVO. When the app is deleted, all of the user's data (not just personal data) is physically and irrevocably deleted from both the local database on the mobile device and the central database without exception.

Liability/ Limitation of liability

The contents of our app were created with the greatest possible care and to the best of our knowledge. However, we do not assume any liability for the topicality, completeness and correctness of the pages. According to § 7 para. 1 TMG (Telemedia Act), we as a service provider are responsible for our own content on these pages under the general laws. According to § 8 to 10 TMG, however, we are not obligated as a service provider to monitor transmitted or stored third-party information. If we become aware of any such infringements, we will remove the relevant content immediately. However, liability in this regard is only possible from the time of knowledge of a concrete infringement.

Medical disclaimer

TB Companion Website

Data protection is of a particularly high priority for the management of the TB Companion. The use of the Internet pages of the TB Companion is possible without any indication of personal data; however, if a data subject wants to use special enterprise services via our website, processing of personal data could become necessary. If the processing of personal data is necessary and there is no statutory basis for such processing, we generally obtain consent from the data subject.

The processing of personal data, such as the name, address, e-mail address, or telephone number of a data subject shall always be in line with the General Data Protection Regulation (GDPR), and in accordance with the country-specific data protection regulations applicable to the TB Companion. By means of this data protection declaration, our enterprise would like to inform the general public of the nature, scope, and purpose of the personal data we collect, use and process. Furthermore, data subjects are informed, by means of this data protection declaration, of the rights to which they are entitled.

As the controller, the TB Companion has implemented numerous technical and organizational measures to ensure the most complete protection of personal data processed through this website. However, Internet-based data transmissions may in principle have security gaps, so absolute protection may not be guaranteed. For this reason, every data subject is free to transfer personal data to us via alternative means, e.g. by telephone. 

1. Definitions

The data protection declaration of the TB Companion is based on the terms used by the European legislator for the adoption of the General Data Protection Regulation (GDPR). Our data protection declaration should be legible and understandable for the general public, as well as our customers and business partners. To ensure this, we would like to first explain the terminology used.

In this data protection declaration, we use, inter alia, the following terms:

2. Name and Address of the controller

Controller for the purposes of the General Data Protection Regulation (GDPR), other data protection laws applicable in Member states of the European Union and other provisions related to data protection is:

TB Companion Team


DZK – German Central Committee against tuberculosis e.V.

Waltehöferstr. 11, House Q
14165 Berlin Germany

Phone: +493081490922

3. Cookies

The Internet pages of the TB Companion use cookies. Cookies are text files that are stored in a computer system via an Internet browser.

Many Internet sites and servers use cookies. Many cookies contain a so-called cookie ID. A cookie ID is a unique identifier of the cookie. It consists of a character string through which Internet pages and servers can be assigned to the specific Internet browser in which the cookie was stored. This allows visited Internet sites and servers to differentiate the individual browser of the dats subject from other Internet browsers that contain other cookies. A specific Internet browser can be recognized and identified using the unique cookie ID.

Through the use of cookies, the TB Companion can provide the users of this website with more user-friendly services that would not be possible without the cookie setting.

By means of a cookie, the information and offers on our website can be optimized with the user in mind. Cookies allow us, as previously mentioned, to recognize our website users. The purpose of this recognition is to make it easier for users to utilize our website. The website user that uses cookies, e.g. does not have to enter access data each time the website is accessed, because this is taken over by the website, and the cookie is thus stored on the user's computer system. Another example is the cookie of a shopping cart in an online shop. The online store remembers the articles that a customer has placed in the virtual shopping cart via a cookie.

The data subject may, at any time, prevent the setting of cookies through our website by means of a corresponding setting of the Internet browser used, and may thus permanently deny the setting of cookies. Furthermore, already set cookies may be deleted at any time via an Internet browser or other software programs. This is possible in all popular Internet browsers. If the data subject deactivates the setting of cookies in the Internet browser used, not all functions of our website may be entirely usable.

4. Collection of general data and information

The website of the TB Companion collects a series of general data and information when a data subject or automated system calls up the website. This general data and information are stored in the server log files. Collected may be (1) the browser types and versions used, (2) the operating system used by the accessing system, (3) the website from which an accessing system reaches our website (so-called referrers), (4) the sub-websites, (5) the date and time of access to the Internet site, (6) an Internet protocol address (IP address), (7) the Internet service provider of the accessing system, and (8) any other similar data and information that may be used in the event of attacks on our information technology systems.

When using these general data and information, the TB Companion does not draw any conclusions about the data subject. Rather, this information is needed to (1) deliver the content of our website correctly, (2) optimize the content of our website as well as its advertisement, (3) ensure the long-term viability of our information technology systems and website technology, and (4) provide law enforcement authorities with the information necessary for criminal prosecution in case of a cyber-attack. Therefore, the TB Companion analyzes anonymously collected data and information statistically, with the aim of increasing the data protection and data security of our enterprise, and to ensure an optimal level of protection for the personal data we process. The anonymous data of the server log files are stored separately from all personal data provided by a data subject.

5. Contact possibility via the website

The website of the TB Companion contains information that enables a quick electronic contact to our enterprise, as well as direct communication with us, which also includes a general address of the so-called electronic mail (e-mail address). If a data subject contacts the controller by e-mail or via a contact form, the personal data transmitted by the data subject are automatically stored. Such personal data transmitted on a voluntary basis by a data subject to the data controller are stored for the purpose of processing or contacting the data subject. There is no transfer of this personal data to third parties.

6. Routine erasure and blocking of personal data

The data controller shall process and store the personal data of the data subject only for the period necessary to achieve the purpose of storage, or as far as this is granted by the European legislator or other legislators in laws or regulations to which the controller is subject to.

If the storage purpose is not applicable, or if a storage period prescribed by the European legislator or another competent legislator expires, the personal data are routinely blocked or erased in accordance with legal requirements.

7. Rights of the data subject

8. Legal basis for the processing

Art. 6(1) lit. a GDPR serves as the legal basis for processing operations for which we obtain consent for a specific processing purpose. If the processing of personal data is necessary for the performance of a contract to which the data subject is party, as is the case, for example, when processing operations are necessary for the supply of goods or to provide any other service, the processing is based on Article 6(1) lit. b GDPR. The same applies to such processing operations which are necessary for carrying out pre-contractual measures, for example in the case of inquiries concerning our products or services. Is our company subject to a legal obligation by which processing of personal data is required, such as for the fulfillment of tax obligations, the processing is based on Art. 6(1) lit. c GDPR. In rare cases, the processing of personal data may be necessary to protect the vital interests of the data subject or of another natural person. This would be the case, for example, if a visitor were injured in our company and his name, age, health insurance data or other vital information would have to be passed on to a doctor, hospital or other third party. Then the processing would be based on Art. 6(1) lit. d GDPR. Finally, processing operations could be based on Article 6(1) lit. f GDPR. This legal basis is used for processing operations which are not covered by any of the abovementioned legal grounds, if processing is necessary for the purposes of the legitimate interests pursued by our company or by a third party, except where such interests are overridden by the interests or fundamental rights and freedoms of the data subject which require protection of personal data. Such processing operations are particularly permissible because they have been specifically mentioned by the European legislator. He considered that a legitimate interest could be assumed if the data subject is a client of the controller (Recital 47 Sentence 2 GDPR).

9. The legitimate interests pursued by the controller or by a third party

Where the processing of personal data is based on Article 6(1) lit. f GDPR our legitimate interest is to carry out our business in favor of the well-being of all our employees and the shareholders.

10. Period for which the personal data will be stored

The criteria used to determine the period of storage of personal data is the respective statutory retention period. After expiration of that period, the corresponding data is routinely deleted, as long as it is no longer necessary for the fulfillment of the contract or the initiation of a contract.

11. Provision of personal data as statutory or contractual requirement; Requirement necessary to enter into a contract; Obligation of the data subject to provide the personal data; possible consequences of failure to provide such data

We clarify that the provision of personal data is partly required by law (e.g. tax regulations) or can also result from contractual provisions (e.g. information on the contractual partner). Sometimes it may be necessary to conclude a contract that the data subject provides us with personal data, which must subsequently be processed by us. The data subject is, for example, obliged to provide us with personal data when our company signs a contract with him or her. The non-provision of the personal data would have the consequence that the contract with the data subject could not be concluded. Before personal data is provided by the data subject, the data subject must contact any employee. The employee clarifies to the data subject whether the provision of the personal data is required by law or contract or is necessary for the conclusion of the contract, whether there is an obligation to provide the personal data and the consequences of non-provision of the personal data.

12. Existence of automated decision-making

As a responsible company, we do not use automatic decision-making or profiling.
