We also may share some of your information with our payment processor if necessary for the proper processing of your ticket purchase.

In all other cases, your information will not be shared with any third parties.

6. How do we store your data?

We store your data in various formats on the server, namely log files (for the information in point 3 of section 2), or in a database (for information under points 1 and 2 of section 2). Passwords you provide us will be stored in hashed form.

7. How long do we store your data?

For the data under row 3 of the table in section 2 (log files), we store your data for a maximum of 7 days. This provides us with the necessary time frame to respond to security incidents.

For the data under rows 1 and 2 of the table in section 2 (e-mail address and personal information), we store your data until the event has come to a conclusion. This allows us to inform you about the event. Also the information may be necessary to combat fraud. If you previously made an account, if you choose to delete your account this information will be deleted as well.

For the data under row 4 of the table in section 2 (username & password), this data will be stored until you choose to delete your account with us.

The data under row 5 of the table in section 2 (payment information) is not stored or processed by us in any form, shape or format. This data is used by our payment processor only to process the payment.

8. Security

We take all appropriate and reasonable technical and organisational measures to protect your personal data from unauthorised access or disclosure, misuse or destruction. Because passwords are stored in hashed form, we cannot re-send you your passwords. In case you lost your password, we provide a password reset form which will send you a link to a password reset form in order for you to be able to regain access to your account.

9. Questions, comments or concerns
