In addition to the definitions specified above, the following definitions are used throughout these General Terms and Conditions for Visitors:

The applicability of these General Terms and Conditions for Visitors shall be without prejudice to the potential applicability of other contractual terms and conditions and/or regulations applied by JetBrains, such as the Terms of Use, and other terms published on the Website from time to time.

Entrance admission

Visitors are given access to KoltinConf upon the presentation of a valid Ticket or valid ID at the entrance and upon the condition that they take into account our Code of Conduct. Furthermore, if a Student Discount was used during the purchase of the Ticket the Visitor will need to provide a valid academic ID together with the valid Ticket or valid ID. You can print your Ticket or present it on a mobile device at the entrance.

For the avoidance of doubt, please be aware that on May 22, 2024 the workshops shall be held while the conference shall be held on May 23 - 24, 2024. If you have purchased a Workshop Ticket this gives you access to attend your pre-selected workshop on May 22, 2024 and provides regular admission to the conference, if you have purchased the Conference Ticket this means you can’t attend the workshops but shall only receive regular admission to the conference.

JetBrains reserves the right to refuse admission to Visitors if it determines, in its sole discretion, that the Visitor poses a threat to the health and/or safety of other Visitors or the staff of KotlinConf and/or the safety of the premises, our partners and the event in general.
