Your data will be stored in our database (TYPO3 v8 with updates, sysext:FORM with custom save to database finisher) on a server in Germany, booked at a German GmbH. The data will additionally be sent to Christophorus Reisen by e-mail (sent by standard mail finisher). Your data will solely be used to fullfill all contractual services you book with the registration to T3BOARD20EU. This includes also forwarding of parts of the data to the hotel (e.g. special needs, name, day of birth), as well as forwarding parts of the data to the skiregion for the skipass (e.g. name, date of birth).
Directly after T3BOARD20EU we will delete your registrations completely from our TYPO3 database (as we did all the years before ...). A copy of the data could remain for a couple of weeks on internal systems, not reachable from the internet, just in case you need some special billing or the like.
At Christophorus Reisen and at the hotel, the data must be stored longer, due to other applicable laws (tax and the like).
