3.Storage of your access data

Each time a user accesses the website and each time a document is downloaded from this website, access data about this action will be saved in a log file on the server.

Each data set consists of:

·The IP address of the device that has opened the website

·The date and time of the request (“time stamp”)

·The name of the file

·The access status (file transferred, file not found, etc.)

·The amount of data which has been transferred

·The page which has requested the file (referrer-URL)

·A description of the type of web browser which has been used (e.g. Mozilla Firefox, Google Chrome or Microsoft Internet Explorer, Apple Safari, Opera, etc.)

The collected data will be analyzed for statistical purposes; it will not be forwarded to third parties for either commercial or non-commercial purposes.

4.Transfer of personal data

Your data will only be transferred from the browser to the web server following encryption. We use a SSL-certificate for this.

5.Contact form

The data will be transferred to the web server in an encrypted way. However, the data will not be stored on the web server, but will be sent automatically from the web server via e-mail to the editorial staff of the website. The data will only be stored until this no longer becomes necessary.

6.Right of access

Users have the right to receive– free of charge – information about their personal data that has been saved. Furthermore, they have the right under statutory regulations to request that their personal data be rectified, blocking and erased.


8.What are cookies and how do we use them?

Cookies are small text modules which are transferred from the Internet to your computer together with the required data. This data will be saved on your computer and will be kept for later visits.We use cookies in some areas. The biophotonics plus website also contains links to external websites that may use cookies. These external websites and their use of cookies are beyond our responsibility, and we cannot inform you of this before following these links.

So-called “session-cookies” are necessary, particularly for the registration process, because we use a so-called single-sign-on concept for reasons of user-friendliness during the authentication and access control to the different areas of our portal.

This comprises the establishment of a “session” between the client and the server which allows you to move through the entire portal without having to re-register for each area. This session is represented by a cookie, in which a randomly generated number is saved.

In addition, your login information (user name, user rights and validity of the session) is saved in a further cookie to control your access. Think of this as substitute login information. Instead of asking you to re-enter your login information, the cookie is sent to the server and accepted as proof of your identity.

8.2Validity of cookies

The validity of both cookies is limited to the time of your visit to our portal. They will be deleted automatically when you close the browser. They are not linked to personal data and no conclusions can be drawn about the user’s activities.

On explicit request, you can optionally allow permanent storage of your user name in a third cookie when registering. This facilitates the login if you frequently visit the portal as you will then only be asked to enter your password. We expressly point out the risks of this procedure as there is the danger of misuse of your login data by third parties.

Most browsers are configured to automatically accept cookies. However, you can deactivate the storage of cookies at any time or you can adjust the browser to inform you as soon as cookies are used.

9.Web analytics

To further optimize the biophotoniks plus website as regards the needs of the users, we analyze the user behavior of visitors to our website (e.g. which content is of most interest? Which content is of least interest?) We use the web analytics provider Matomo (former Piwik) on our website for this purpose.

Matomo uses cookies to analyze the user behavior of visitors to the website. The user information (including the anonymized IP-address) which is generated by the cookie will be transferred to our server for analysis where it is saved for later evaluation and optimization of our website contents. Even before your IP-address is transferred to our server, it will be anonymized by deleting the last two blocks of numbers, thus ensuring that you remain completely anonymous as a user. The information about how visitors to our website use our website will not be forwarded to third parties, unless we are obliged to do so by law, e.g. in the case of a judicial order.

10. Objection to analytical cookies

If you do not approve the storage and analysis of this data resulting from your visit to our website, there are two ways in which you can stop the analysis of your user behavior:

First, you can permanently prevent the use of cookies by changing the corresponding settings in your browser software. However, in this case you may not be able to use all of the functions of our website because your browser then blocks all cookies, not only those cookies which we save on your computer for analytical purposes. Cookies are also necessary to log into the exclusive member area.

Secondly, you can object to the storage and use below via mouse klick at any time. In this case, a so-called opt-out cookie will be saved in your browser which consequently leads to Matomo no longer collecting any session data.

Attention: If you delete cookies on your computer (e.g. by activating the private/incognito mode in your browser), the opt-out cookie will also be deleted and may have to be reactivated so that we do not save an analysis cookie on your computer.


11.Legal basis and time of storage

The legal basis for data processing pursuant to the preceding paragraphs is point f) in Article 6 (1) of the European General Data Protection Regulation. Our interest in data processing is, in particular, to ensure the operation and security of the website, the analysis of the way visitors use the website as well as the simplification of the use of the website.

Unless otherwise specified, we only save personal data as long as is necessary for the fulfillment of the respective purposes.
