General information on the collection of personal data when visiting our online offer

When you visit our website, data is inevitably collected that has to be stored or processed in order to be able to show you this website.

As a matter of principle, all data that is no longer necessary for the fulfilment of our tasks is deleted at regular intervals.

The basis for data processing is Art. 6 Para. 1 lit. f DSGVO. According to this, we may process your personal data if we do so on the basis of a legitimate interest. This legitimate interest is specifically to be able to display our website to you.

In the following, we explain which data we collect, process and possibly also store for a longer period of time.

Indirect data collection (server logs)

When you visit our website, our servers collect so-called server log files. These files are only stored for the duration of your session. However, accesses that are not legitimate, i.e. do not represent normal use of our service, may be stored for longer. This is done to avert danger and to ensure the IT security of our systems.

Concretely, such data could be

  • Operating system used
  • Browser used
  • date and time of the server request
  • IPv4 address and subnet, IPv6 address and prefix

The collection of the above-mentioned data for the provision of the website and its storage in log files (temporarily per session) is absolutely necessary for the operation of the offer, so that you have no direct possibility of objection. Of course, this does not affect your right of inspection or deletion (see "Your rights"). By calling up our website, you give us your consent to process this technical data (Art. 6 para. 1 p. 1 lit. a DSGVO). Furthermore, Art. 6 para. 1 p. 1 lit. f DSGVO is a legal basis for the collection of the data and its storage in log files, which we cite. We only store this log data (for longer periods) in order to ensure the smooth and secure operation of our website.

Special features of the subpage

The subpage is provided by l3montree to offer you and other users of the StampLab application offered by l3montree a possibility to find out if, when and why there are/were possible malfunctions or failures of the StampLab application. To ensure that this source of information remains accessible even in the event of major (e.g. infrastructural) problems and that there is access to information, this page is not delivered via our productively used servers, but server instances that are operated in the Open Telekom Cloud. Therefore, the information mentioned above (indirect data collection (server logs), e.g. IP address of your request) is processed by Telekom to a limited extent for us (infrastructure provision, server + network) in the event that the subpage is accessed. Further information can be found here. The collection of this data for the provision of the website and its storage in log files is absolutely necessary for the operation of the offer, so that you have no direct possibility to object. Of course, this does not affect your right to inspect and delete your data (see "Your rights"). By calling up our website, you give us your consent to process this technical data (Art. 6 para. 1 p. 1 lit. a DSGVO). Furthermore, Art. 6 para. 1 p. 1 lit. f DSGVO is a legal basis for the collection of the data and its storage in log files, which we cite. We only store this log data (possibly for longer periods) in order to ensure the smooth and secure operation of our website.

Collection of further data when visiting our online offer

In addition to the technical data mentioned above, we collect further data when you visit our website. We use the Umami service, an open source analytics application, to collect anonymous data about the behaviour of our website visitors. We run our own instance of this service on our own servers - so no data gets to third parties. We may collect the following data:

  • the browser used (e.g. Google Chrome)
  • the type of device (e.g. laptop or mobile)
  • the screen resolution
  • the language used
  • the operating system (e.g. Android)
  • an anonymous session ID (to avoid duplicating your website visit)
  • which URLs you visit (which subpages)
  • from which URL you came to our website (referrer)
  • how long you were on our site

We collect this data in order to be able to improve our website and to offer you a good experience when visiting it, as well as to be able to guarantee smooth operation. We cite Art. 6 Para. 1 lit. f DSGVO as the legal basis for this.

Contact by e-mail

When you contact us, e.g. by e-mail, we record your contact data until the reason for the contact loses its relevance and, for example, a reply from our side is no longer necessary. Of course, this does not affect your right of access or deletion (see "Your rights"). If you contact us by e-mail, please note that the confidentiality of e-mails or other electronic forms of communication on the Internet cannot be guaranteed.

Use of Google Analytics and cookies on

We use Google Analytics to analyze website usage. The data obtained from this is used to optimize our website as well as advertising measures.

Google Analytics is provided to us by Google Ireland Limited (Gordon House, Barrow Street, Dublin 4, Ireland). Google processes website usage data on our behalf and is contractually committed to measures to ensure the security and confidentiality of the processed data.

During your website visit, the following data is recorded, among others:

  • Pages viewed
  • The achievement of "website goals" (for example, contact requests and newsletter sign-ups)
  • Your behavior on the pages (for example, dwell time, clicks, scrolling behavior)
  • Your approximate location (country and city)
  • Your IP address (in shortened form, so that no clear assignment is possible)
  • Technical information such as browser, Internet provider, terminal device and screen resolution
  • Source of origin of your visit (i.e. via which website or advertising material you came to us)

No personal data such as name, address or contact details are ever transferred to Google Analytics.

This data may be transferred to Google servers in the USA. We would like to point out that the same level of data protection cannot be guaranteed in the USA as within the EU.

Google Analytics stores cookies in your web browser for a period of two years since your last visit. These cookies contain a randomly generated user ID with which you can be recognized during future website visits.

The recorded data is stored together with the randomly-generated user ID, which enables the evaluation of pseudonymous user profiles. This user-related data is automatically deleted after 14 months. Other data remains stored in aggregated form indefinitely.

If you do not consent to the collection, you can prevent it by installing the browser add-on once to disable Google Analytics or by rejecting cookies via our cookie settings dialog.

Only after your active consent ("Agree" button) cookies are set by Google and only then begins an analysis. As long as you have not agreed or if you click on "Decline", no cookies (except a technically necessary one to save your decision) will be set and no data will be collected or transmitted.

We cite Art. 6 Para. 1 lit. a DSGVO as the legal basis.

Passing on personal data to third parties

In principle, we do not pass on any data to third parties. However, we do link to third-party content. These are, for example, links to social networks such as Instagram and Twitter, which are important for the distribution of our content. We protect privacy by not directly integrating third-party content. Users who leave our site and visit third-party sites via provided links should bear in mind that on these third-party sites, the respective data protection regulations of the third party apply, over which we have no influence. We are not responsible for the protection of your data when visiting external websites, services or offers.

How we protect your data

This website uses TLS encryption for security reasons and to protect the transmission of confidential content, such as requests you send to our server. This procedure is implemented for all communication between the website and our servers.

If TLS encryption is activated, the data you transmit to us cannot be read by third parties.

Furthermore, our employees are also obliged to maintain the confidentiality of your data.

Even though we use all available security mechanisms, we would like to point out that data transmission on the Internet can have security gaps. Complete protection of data against access by third parties is not possible.

Your rights

Revocation of your consent to data processing

By using our offer, you agree to the processing of the data collected for the provision of the offer. You have no direct right of objection here. However, you can of course request the deletion of all data.

Many data processing procedures are only possible with your express consent. You can revoke your consent at any time. All you need to do is send us an informal e-mail. The legality of the data processing carried out until the revocation remains unaffected by the revocation.

Right of complaint to the competent supervisory authority

In the event of violations of data protection law, the person concerned has the right to lodge a complaint with the competent supervisory authority. The competent supervisory authority in matters of data protection law is the State Data Protection Commissioner of the federal state in which our company is based. A list of the data protection officers and their contact details can be found at the following link:

Right to data portability

You have the right to have data that we process on the basis of your consent or in performance of a contract handed over to you or to a third party in a common, machine-readable format. If you request the direct transfer of the data to another controller, this will only be done insofar as it is technically feasible.

Information, blocking, deletion and correction

Within the framework of the applicable legal provisions, you have the right at any time to free information about your stored personal data, its origin and recipient and the purpose of the data processing and, if applicable, a right to correction, blocking or deletion of this data. For this purpose, as well as for further questions on the subject of personal data, you can contact us at any time at the address given in the imprint.

Further information

Criteria for determining storage periods
