github offers free publicly accessible data storage. Many people use that to present their personal profile where they e.g. advertise for freelancing services. An example url could be http://username.github.io.
If I have such a personal page where I advertise services, do I need to make sure I have an Impressum and a data privacy statement to comply with the new General Data Protection Regulation DSGVO?
It would be hosted by github and linked to and accessible only via github, not e.g. a domain of mine. Though it would still be possible to e.g. include a contact form that sends visitor data to my email address.
