1. Principles of data processing
Lukas Günther Teissl processes personal data exclusively in accordance with the applicable statutory provisions. Processing only takes place where this is necessary for the initiation, execution or settlement of contracts as well as for the fulfilment of legal and regulatory obligations.
Without separate consent, personal data is only used if this is strictly required for the provision of services, invoicing or the secure technical operation of the systems offered.
2. Disclosure of data & rights of data subjects
2.1 Disclosure of personal data
Personal data is disclosed exclusively to carefully selected service providers or partner companies, where this is required for the fulfilment of contracts or for the execution of specific business processes. This includes in particular the transfer of name, address, telephone number and e-mail address to domain registries (e.g. ICANN) in the context of domain registrations. These bodies may store data in publicly accessible WHOIS directories.
In addition, data may be transferred to technical operators, IT security service providers and to companies within the international corporate group (EU / UK / USA), insofar as this is necessary for internal administrative and settlement purposes. Any transfers to third countries are made exclusively in accordance with the GDPR (in particular Art. 44 et seq.) and with appropriate safeguards in place (e.g. standard contractual clauses, technical and organisational measures).
2.2 Rights of data subjects
Data subjects have in particular the following rights:
- Right of access to the data stored about them,
- Rectification of inaccurate or incomplete data,
- Erasure of data (“right to be forgotten”), where no retention obligations apply,
- Restriction of processing,
- Data portability in a structured, commonly used format,
- Objection to the processing of personal data,
- Withdrawal of consent granted, with effect for the future.
Requests for access and other data subject rights can be asserted using the communication channels specified in the Contact options section.
3. Data security & IT security
Modern technical and organisational security measures are used to protect personal data against unauthorised access, loss or misuse. These include in particular:
- encrypted data transmission (e.g. TLS/SSL),
- secure server locations within the EU, the United Kingdom and the USA,
- role-based access concepts and strong authentication procedures,
- continuous updating and monitoring of IT systems,
- internal policies on data protection, confidentiality and information security.
The measures implemented are reviewed on a regular basis and adapted to the current state of the art.
