What type of personal data are collected?

  • On behalf of its employees, the ECB is updating its Microsoft Teams instance with an initial set of data to ensure that you can connect, logon and effectively use the platform. This set of data includes information like username, first name, surname, e-mail address, organisational unit, phone extension, mobile number and office number.

How long will the ECB keep personal data?

The personal data are stored for a maximum of one year before being deleted.

Chat and channel messages are stored for a period of 1 year.

Any file stored or edited via Microsoft Teams has a defined retention period of 7 days counting from the creation date within the platform.

When a user is deleted from the Microsoft Teams services, the retention period for messages is a maximum of 90 days. However, if a user (or the ECB, on the user's behalf) deletes the personal data, all copies of the personal data are deleted within 30 days.

The diagnostic data collected through Microsoft Teams’s client software are stored for 30 days, while the service-generated data is kept for a maximum of 180 days.

Should the ECB terminate its contractual relationship with Microsoft, all corresponding personal data will be deleted between 90 and 180 days after the service termination.

What are your rights?

You have the right to access your personal data and correct any data that is inaccurate or incomplete. You also have (with some limitations) the right to delete your personal data, to object or to restrict the processing of your personal data in line with Regulation (EU) 2018/1725.

Addressing the European Data Protection Supervisor

If you consider that your rights under Regulation (EU) 2018/1725 have been infringed as a result of the processing of your personal data, you have the right to lodge a complaint with the European Data Protection Supervisor at any time.

  1. Microsoft Teams on ECB laptops, ECB mobile devices and non-ECB laptops connected via Citrix.
  2. The service-generated data includes all data ‘generated’ or ‘derived’ by Microsoft through the operation of an online service. Microsoft aggregates this data from its online services and uses it to make sure performance, security, scaling, and other services that impact the customer experience are operating at the levels their customers require.
  3. In case of technical issues on the Microsoft Teams platform, support is delivered by Microsoft based on a globally distributed organisation (using the ‘follow-the-sun’ workflow model).
  4. Service-generated data is transferred from the European Union datacentres where they are initially created to centralised Microsoft back-end systems located in the United States for longer term storage. Prior to transfer, end user identifying information is pseudonymised as a privacy protective measure, so that any personal data in service-generated data transferred out of the European Economic Area is limited to pseudonymous data.
    Pseudonymised data is data in which a personal identifier has been replaced with a value that does not directly identify a person (such as a numeric identifier that can no longer be attributed to a specific person without the use of additional information).
    Pseudonymised data is defined according to ISO standard ISO/IEC 19944:2017 (8.3.3). It does not identify users themselves, but it does enable distinguishing one user from another, such as for accurate counting. Unlike anonymised data, pseudonymised data could be used to identify a person indirectly (such as when combined with other data such as the person’s function, title, and organisation). Pseudonymised data is therefore deemed to be personal data under the EUDPR.
    ‘R6Y04H4VfUWcGC3’ is an example of pseudonymised data derived from someone’s Microsoft 365 e-mail address. Nothing within this cryptographically obscured alphanumeric string can be directly traced to the person's identity.
