Microsoft Teams (as part of Microsoft Office 365 Cloud Services) is an Internet-based collaboration and communication solution for individual users and groups that can be used across companies.
When you use Microsoft Teams, personal data about you is processed. Please note that this Privacy Notice only informs you about the processing of your personal data by MEWA if you use Microsoft Teams together with us.
Further information on the processing of your personal data by MEWA outside of the use of Microsoft Teams can be found at:
1. Purposes of Processing and Legal Bases
We process your personal data for the following purposes:
• Carrying out communication and collaboration activities for the purpose of processing and fulfilling contracts concluded with our corporate customers and partners;
• implementing measures for the improvement of our products/services and for strengthening our customer relationship;
• carrying out surveys, for example, for market research or customer satisfaction (customer feedback);
2. Information About the Processing and Categories of Personal Data in Connection with the Use of Microsoft Teams
Certain information is automatically processed when you use Microsoft Teams:
2.1 Your IP address that is used to access the Microsoft Teams applications within Microsoft Office 365.
2.2 Your username (access data for Microsoft Office 365),
Data that you yourself have stored in your Microsoft account (e.g. optionally a mobile phone number for the two-factor authentication).
2.3 Identification features:
Information about you that may identify you as a user, sender, or recipient of data within Microsoft Teams. This includes the following master data:
Surname, first name, business contact details such as telephone number and email address.
Data (such as an optionally stored profile picture) can also be viewed in your profile. This information is visible to you at all times in your profile and can be customised by you.
2.4 Data required for authentication and operation
Microsoft Teams processes all user activities, such as the time of access, date, type of access, information about the data/files/documents you have accessed within Microsoft Teams, and all activities, such as creating, modifying, deleting a document, setting up a team (and channels in Teams), starting a chat and the course of discussions in the chat.
2.5 Data you provide in the course of communication with Microsoft Teams
Personal data that you contribute to documents or chat discussions in Microsoft Teams (e.g. documents such as presentations, tables, etc.)
3. Disclosure of Data
Apart from the cases explicitly mentioned in this Privacy Notice, your personal data will only be passed on if it is legally permissible or necessary (e.g. for license checks).
3.1 If it is necessary for the clarification of an illegal or abusive use or for an investigation, personal data shall be forwarded to the law enforcement authorities or other authorities and, if applicable, to injured third parties or legal advisers. MEWA is legally obliged to provide information to certain public bodies upon request. These are law enforcement agencies, authorities that pursue administrative offences that have been subject to fines and the tax authorities.
3.2 Microsoft is a processor of personal data and is subject to the instructions of MEWA as the data controller within the meaning of the GDPR when processing personal data. Any transfer of personal data in the course of Microsoft’s provision of the service is justified because we have carefully selected and verified the external service provider as a processor in accordance with Art. 28 (1) of the GDPR. All personal data is processed according to our instructions. Microsoft processes personal data only on servers located within the EU.
4. Transfer to Third Countries or International Organisations
Recipients of personal data may also include recipients located outside your country, in particular, outside the European Economic Area (EEA). This may also be a country for which the European Commission has not yet made an adequacy decision on whether this country ensures an adequate level of data protection (third countries), for example, the USA. In this case, it is determined by appropriate means that all recipients based outside the EEA shall ensure an adequate level of data protection (Art. 45 of the GDPR) for such personal data and that technical and organisational security measures are taken to prevent personal data from being accidentally deleted or to protect it against unlawful destruction, accidental loss or modification, unauthorised disclosure or access and against all other unlawful forms of processing. The appropriate means can be accessed via the contact details that have been specified. Pursuant to the applicable legal provisions, onward transfers of personal data are subject to the necessary appropriate requirements regarding onward transfers.
5. Storage and Retention Periods
We process personal data only for as long as is necessary to fulfil the respective processing purposes. As soon as personal data is no longer required, we shall erase personal data from our systems and records and/or take measures to anonymise personal data so that it can no longer be used to identify you. In order to comply with legal requirements, however, we must keep or save certain personal data for a specific time. Such data includes, for example, documentation, certification and the retention obligations of national trade and taxation law. For example, the storage and retention periods relevant for us are generally three to ten years or, in exceptional cases, up to 30 years in accordance with the law applicable in Germany.
6. Your Rights as a Data Subject
Your legal rights: Under the terms established by applicable data protection law (including the GDPR and German Federal Data Protection Act, or BDSG for short and UK data protection legislation), you have the following rights:
6.1 Right of access: You have the right to obtain information about whether or not your personal data is being processed. Where this is the case, you have the right to be provided with information about personal data, for example, the purposes of the processing, the categories of personal data concerned and the recipients or categories of recipient to whom the personal data has been or will be disclosed. You have the right to receive a copy of the personal data undergoing processing. For any further copies which you request, we may charge a reasonable fee based on administrative costs.
6.2 Right to rectification: You have the right to request that we rectify inaccurate data concerning your person. Taking into account the purposes of the processing, you shall have the right to have incomplete personal data made complete, including by means of providing a supplementary statement.
6.3 Right to erasure (Right to be forgotten): You have the right to request that we delete your personal data.
6.4 Right to restriction of processing: You also have the right to request the restriction of processing of your personal data. In this case, the corresponding data will be marked and may only be processed by us for certain purposes.
6.5 Right to data portability: You have the right to receive your personal data, which you have provided to us, in a structured, commonly used and machine-readable format. You have the right to transmit such personal data to another controller without us interfering.
6.6 Right to object: You have the right to object, on grounds relating to your particular situation, at any time to the processing of your personal data. Where appropriate, we must stop processing your personal data. If you exercise your right to object, we will no longer process your personal data for such purposes. There are no costs for exercising this right. Such a right of objection may not exist, in particular, if the processing of your personal data is necessary in order to take measures before concluding a contract or to fulfil an already concluded contract.
In the event of any complaints, you also have the right to lodge a complaint with the relevant supervisory authority.
