Collection and processing of personal data

Data Protection at ista

The protection of your personal data is very important to ista.

ista complies with the legal data protection regulations and does everything to keep your and your customer’s/tenant‘s data confidential. All personal data is collected, processed and used in accordance with the provisions of the General Data Protection Regulation (GDPR) and only for the purposes of contract processing, fulfilment of legal obligations or for safeguarding our own legitimate business interests with regard to the advice and support of the customers as well as the demand-oriented product design.

All service providers of ista dealing with the processing of personal data also comply with the provisions of the GDPR in accordance with Art. 28 GDPR. Compliance is monitored by our data protection officer.

Collection and processing of personal data

Each time a user accesses the ista website and each time a file is accessed, data about that activity is stored in a log file. This data is not related to a person; so ista cannot trace back which user has retrieved what data.

In detail, the following data record is saved for each call:

• Name of the file

• Date and time of access

• Amount of data transferred

• Message whether the call was successful

• Anonymous IP-Address

• If necessary, operating system and browser software on your computer

• As well as the website from which you visited the ista website

Personal user profiles cannot be created.

The above-mentioned data is evaluated for statistical purposes only.

Personal data will only be collected if you give it to ista on your own - for example, when registering for a survey or conducting a contract. A transmission of your data to third parties does not take place, unless ista is legally obliged to do so. Insofar as external service providers come into contact with your personal data, ista has ensured that they comply with the provisions of data protection laws through legal, technical and organizational measures as well as regular checks.
