Therefore, PTB would like to inform you about the personal data processed during the use of this website and the rights granted to you in this context.
I. Data Processing

Once you log in to your account, PTB processes the following data by means of automatic logging:

  • Date and Time
  • IP address
  • Whether the login attempt has been successful

The processing is based on Article 6 (1) e) of the General Data Protection Regulation (GDPR) in conjunction with § 3 of the Federal Data Protection Act (BDSG) for the maintenance of the availability and integrity of its information technology systems and website to ensure PTB’s ability to render services according to its charter.
Such data are stored temporarily, for a maximum of seven (7) days, and are used for statistical purposes, to improve the website and to ensure data protection and information security at PTB.
PTB reserves the right to further scrutinize this data should there be evidence of criminal acts or cyber-attacks and forward the data to the responsible law enforcement authorities and/or the Federal Office for Information Security (Bundesamt für Sicherheit in der Informationstechnik - BSI).
There will be no further use or disclosure to third parties

When accessing this website, so-called temporary session cookies will be stored on your device to facilitate navigational features. These cookies do not contain personal data and expire after your session has ended.
Techniques such as Java applets or Active X controls, which enable tracking of user access behavior, are not utilized.

If you contact PTB via a contact form or by e-mail, PTB will process given personal data for the purpose of processing your request and contacting you.
The legal basis on which your data will be processed depends largely on the nature of your request. If PTB acts by exercising official authority or within the scope of its statutory tasks, processing will be based on Article 6(1) e), (3) GDPR in conjunction with § 3 Federal Data Protection Act (BDSG). Your data will be deleted once your request has been processed, notwithstanding statutory retention periods. The nature of your request will determine, which periods will be applicable. Retention periods of inquiries from the general public will be determined in accordance with the statutory periods of the Registry Directive (Registraturrichtlinie), which supplements the Joint Rules of Procedure of the Federal Ministries (Gemeinsame Geschäftsordnung GGO). Further information can be requested informally or by way of a request of information pursuant to Article 15 GDPR (see below). Any further use or disclosure to third parties, except in cases provided for by law and for the prosecution of criminal offenses or for the purpose of countering threats and dangers, will only be made if you have given your consent.

Access to TraCIM’s services will be granted to you after registering as a user providing personal data. Upon registering, a user account will be created processing the data entered into the registration form. The personal data entered during registration will be used by PTB for the purpose of assigning and individualizing the user account, checking user’s individual access authorization, billing purposes and where appropriate, for sending information on restoring access to a user account e.g. after a new password has been requested.
The processing of your data is based on performance of a contract according to Article 6(1) b) GDPR.
The personal data you entered during registration will be deleted by PTB:

  1. Five years after your last login to TraCIM’s services, in case you did not order a chargeable service. This period should be sufficient to utilize TraCIM’s sample data to develop your own products or for finishing scientific work such as PhD-theses. You may, however, request deletion of your account at any time, notwithstanding statutory retention periods.
  2. 10 years after the year you last logged in to TraCIM’s services has ended, in case you ordered a chargeable service resulting in a PTB test report. This period is based on German retention obligations for certificates, such as calibration certificates and fiscal retention periods according to § 147 (1), (3) and (4) of The Fiscal Code of Germany (AO).
Any further use or disclosure to third parties, except in cases provided for by law and for the prosecution of criminal offenses or for the purpose of countering threats and dangers, will only be made if you have given your consent.
