This privacy policy explains what information we collect and what we use it for. It also explains how and for what purpose this happens. Please note that data transmitted via the internet (e.g. via email communication) may be subject to security breaches. Complete protection of your data from third-party access is not possible.

Data collection on our website

Cookies

Some of our web pages use cookies. Cookies do not harm your computer and do not contain any viruses. Cookies help make our website more user-friendly, efficient, and secure. Cookies are small text files that are stored on your computer and saved by your browser. Most of the cookies we use are so-called “session cookies.” They are automatically deleted after your visit. Other cookies remain in your device’s memory until you delete them. These cookies make it possible to recognize your browser when you next visit the site. You can set your browser so that you are informed about the setting of cookies and only allow cookies in individual cases, exclude the acceptance of cookies for certain cases or in general and activate the automatic deletion of cookies when closing the browser. If cookies are deactivated, the functionality of this website may be limited. Cookies that are required to carry out the electronic communication process or to provide certain functions that you have requested (e.g. shopping cart function) are stored on the basis of Art. 6 (1) (f) DSGVO. The website operator has a legitimate interest in storing cookies for the technically error-free and optimized provision of its services. Insofar as other cookies (e.g. cookies for analyzing your surfing behavior) are stored, these are treated separately in this privacy policy.

Server log files

The website provider automatically collects and stores information that your browser automatically transmits to us in “server log files”. These are: • Browser type and browser version • Operating system used • Referrer URL • Host name of the accessing computer • Time of the server request • IP address These data will not be combined with data from other sources. The storage period of the server log files is 60 days. The basis for data processing is Art. 6 (1) (f) DSGVO, which allows the processing of data to fulfill a contract or for measures preliminary to a contract.

Contact form

Should you send us questions via the contact form, we will collect the data entered on the form, including the contact details you provide, to answer your question and any follow-up questions. We do not share this information without your permission. We will, therefore, process any data you enter onto the contact form only with your consent per Art. 6 (1)(a) DSGVO. You may revoke your consent at any time. An informal email making this request is sufficient. The data processed before we receive your request may still be legally processed. We will retain the data you provide on the contact form until you request its deletion, revoke your consent for its storage, or the purpose for its storage no longer pertains (e.g. after fulfilling your request). Any mandatory statutory provisions, especially those regarding mandatory data retention periods, remain unaffected by this provision.

Inquiry by e-mail, telephone or fax

If you contact us by e-mail, telephone or fax, your inquiry including all resulting personal data (name, inquiry) will be stored and processed by us for the purpose of processing your request. We do not pass on this data without your consent. The processing of this data is based on Art. 6 (1) (b) DSGVO, if your request is related to the performance of a contract or is necessary for the implementation of pre-contractual measures. In all other cases, the processing is based on our legitimate interest in the effective processing of the requests sent to us (Art. 6 (1) (f) DSGVO) or on your consent (Art. 6 (1) (a) DSGVO) if this has been requested; the consent can be revoked at any time. The data you send to us via contact requests will remain with us until you request us to delete it, revoke your consent to store it or the purpose for storing the data no longer applies (e.g. after your request has been processed). Mandatory legal provisions - in particular legal retention periods - remain unaffected.

If you would like to receive the newsletter offered on the website, we require an e-mail address from you as well as the information in which language you would like to receive the newsletter. Further data is not collected by us or only on a voluntary basis. We use this data exclusively for sending the requested information and do not pass it on to third parties. Subsequently, you will receive an e-mail in which a confirmation link will be sent to you (double opt-in procedure). If you activate the confirmation link, your data will be processed and you will receive the newsletter. If you do not wish to receive the newsletter, you can ignore the mail and no data will be stored. The processing of the data entered in the newsletter registration form is based exclusively on your consent (Art. 6 (1) (a) DSGVO). You can revoke your consent to the storage of the data, the e-mail address and their use for sending the newsletter at any time via the “unsubscribe” link in the newsletter. The legality of the data processing operations already carried out remains unaffected by the revocation. When opening the newsletter mail, this action is registered and your IP number is stored in a list. Likewise, clicking on links contained in the mail is registered with the address of the link and your IP address. The saved data is stored in a list that is maintained by us. The Saas solution brevo is used to send the newsletter. As part of this registration, you agree that your entered data will be transmitted to Sendinblue GmbH (“Brevo”). Please note the privacy policy and general terms of use of Sendinblue GmbH (“Brevo”). Brevo’s data centers are located in the EU and account data is encrypted before being secured on three geographically separate servers. The data you provide to us for the purpose of receiving the newsletter will be stored by us until you unsubscribe from the newsletter and will be deleted after you unsubscribe from the newsletter. Data that has been stored by us for other purposes (e.g. e-mail addresses for the member area) remains unaffected by this.

opsi Map

The spatial representation of the current opsi installations on our website is based on maps from OpenStreetMap (OSM). We integrate the map material of OpenStreetMap on the server of the OpenStreetMap Foundation, St John’s Innovation Centre, Cowley Road, Cambridge, CB4 0WS, Great Britain. The United Kingdom is considered a secure third country under data protection law. This means that the United Kingdom has a level of data protection that is equivalent to the level of data protection in the European Union. When using the OpenStreetMap maps, a connection is established to the servers of the OpenStreetMap Foundation. In doing so, among other things, your IP address and other information about your behavior on this website may be forwarded to OSMF. OpenStreetMap may store cookies in your browser or use similar recognition technologies for this purpose. The use of OpenStreetMap is in the interest of an appealing presentation of the opsi installations. This represents a legitimate interest in the sense of Art. 6 (1) (f) DSGVO. The entry of your opsi installation is voluntary. If a corresponding consent was requested, the processing is exclusively based on Art. 6 (1) (f) DSGVO and § 25 para. 1 TTDSG, as far as the consent includes the storage of cookies or the access to information in the end device of the user (e.g. device fingerprinting) in the sense of the TTDSG. The consent can be revoked at any time. https://wiki.osmfoundation.org/wiki/Privacy_Policy
