This privacy policy informs you in accordance with Art. 13 and 14 GDPR about the processing of personal data on this website. The use of our pages is generally possible without providing personal data; no tracking tools, analytics services or advertising networks are used.
The controller within the meaning of the GDPR is:
Gruhn SoftwareA data protection officer is not required to be appointed (Art. 37 GDPR in conjunction with Section 38 BDSG, as there is no extensive processing of special categories of data and fewer than 20 persons are involved in data processing).
This website is hosted by:
IONOS SE (formerly 1&1 Internet SE)A data processing agreement pursuant to Art. 28 GDPR is in place with IONOS. Data processing takes place exclusively on servers in Germany.
Each time the website is accessed, the web server automatically collects and stores information in so-called server log files: browser type and version used, operating system of the accessing system, referrer URL, hostname of the accessing computer, date and time of access, IP address and HTTP status code.
This data is technically required for delivering the website and serves to ensure system security. No merging with other data sources takes place. The legal basis is Art. 6(1)(f) GDPR; our legitimate interest lies in the secure, stable and error-free provision of the website as well as the detection and prevention of attacks. The interests of data subjects do not prevail, as the data is not used for profiling purposes and pseudonymisation is achieved by truncating the IP address. Log files are automatically deleted by IONOS after no more than 8 weeks; a shorter retention period is not configurable in IONOS standard web hosting.
If you contact us by email or phone, we process the transmitted data (name, email address, phone number, message content) exclusively to handle your enquiry.
The legal basis is Art. 6(1)(b) GDPR if your enquiry is aimed at concluding a contract, otherwise Art. 6(1)(f) GDPR (legitimate interest in handling customer enquiries). The data will be deleted once the enquiry has been fully processed, unless statutory retention obligations apply.
This website does not use any cookies for advertising, analytics or tracking purposes. No tracking pixels, social media plugins or web analytics services are used. Personal data is not collected or shared for advertising or analytics purposes.
Insofar as the web server sets technically necessary session cookies (e.g. through the hosting infrastructure of IONOS), these serve exclusively for the technical operation of the website and do not contain any personal data. They are deleted when the browser is closed. The legal basis is Section 25(2) No. 2 TDDDG (technically strictly necessary). A cookie banner is not required.
The “About us” section contains a direct link to Google Maps. By clicking this link, you leave our website and access the service of Google LLC, 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA. This may result in the transfer of personal data to a third country (USA). Google LLC is certified under the EU-US Data Privacy Framework (adequacy decision of the EU Commission of 10 July 2023, Art. 45 GDPR). From the moment you click the link, Google’s privacy policy applies. No Google Maps service is embedded in our website; data is only transferred to Google if you actively click the link.
Insofar as we process personal data, this is based on the following legal bases of the GDPR:
Personal data is only stored for as long as necessary for the respective processing purpose or as required by statutory retention periods (e.g. tax and commercial law obligations under Section 147 AO, Section 257 HGB: up to 10 years). After the period expires or the purpose ceases to apply, the data is deleted or blocked.
You have the following rights regarding your personal data:
To exercise your rights, please contact us using the details provided in Section 1. The competent data protection supervisory authority is the State Commissioner for Data Protection and Freedom of Information of Rhineland-Palatinate, Postfach 30 40, 55020 Mainz, www.datenschutz.rlp.de.
No automated decision-making including profiling within the meaning of Art. 22 GDPR takes place.
For security reasons and to protect the transmission of confidential content, this website uses SSL/TLS encryption (Art. 32 GDPR). You can recognise an encrypted connection by the browser’s address bar changing from “http://” to “https://” and by the lock icon in the browser bar. When SSL/TLS encryption is activated, third parties cannot read the data you transmit to us.
Please note, however, that data transmission over the internet may have security vulnerabilities despite SSL/TLS (e.g. when communicating via unencrypted email). Complete protection of data against access by third parties is not possible. For particularly confidential communications, we recommend contacting us by phone.
The provision of personal data is neither legally nor contractually required to visit this website. However, without voluntarily provided contact data (e.g. email address for an enquiry), we may not be able to process incoming enquiries fully or at all (Art. 13(2)(e) GDPR).
This privacy policy is currently valid (as of: April 2026). Due to the further development of our website or changes in legal requirements, it may become necessary to amend this privacy policy. The current version is always available at www.gruhnsoft.de/en/privacy.html.
