The following paragraphs give details on the different data processing operations.
When using our website, your IP address is used by our web server to provide the requested contents. This is technologically necessary and inherent to every website. We generally do not store personally identifiable information in logs, except for data about your browser and operating system (HTTP User Agent). In case of errors (HTTP status codes 4XX and 5XX), more information, including your IP address, gets stored in logs together with the requested page and time of the request. This supports our error analysis, which is our legitimate interest within the meaning of Art. 6 Par. 1 Point (f) EU-GDPR.
Cookies are small pieces of text data that can get saved to your web browser by websites you visit. They may allow to uniquely identify your web browser over multiple visits to a site. We use a cookie ("sessionid") to maintain your login status when you log into our website, which gets deleted upon logout. That cookie links your web browser to your registered account. Another cookie ("csrftoken") is used to protect you from a certain kind of security attacks (CSRF attacks). Both cookies are necessary to provide the website securely, which is our legitimate interest within the meaning of Art. 6 Par. 1 Point (f) EU-GDPR.
In order to participate in the competition, you register an account on our website. The data you enter in the registration form gets stored on our servers. Each account is associated with a team, which may consist of an arbitrary number of individuals. Some of the account information, such as username and affiliation, will be displayed publicly on the competition scoreboard, the list of registered teams, and similar pages. This is our legitimate interest within the meaning of Art. 6 Par. 1 Point (f) EU-GDPR. Your email address is used to provide you with relevant information about the competition, alert you about problems, coordinate price pay-outs, and comparable purposes. That is necessary to run the competition, therefore Art. 6 Par. 1 Point (b) EU-GDPR applies.
On some pages of our website, we embed videos hosted by the third-party platform YouTube. When opening such a page, YouTube will learn that you visit it and/or that you watch the embedded video. YouTube will also receive information about your IP address, browser and operating system and (at least) process your IP address to deliver the video. Improving the contents of our website by embedding videos is our legitimate interest within the meaning of Art. 6 Par. 1 Point (f) EU-GDPR.
For residents of the European Economic Area, YouTube is run by:
Google Ireland Ltd.
Gordon House, Barrow Street
Google Ireland Ltd. may share data with its parent company Google LLC in the United States. Google LLC is a participant in the Privacy Shield framework, which promises compliance with EU-GDPR for data processing under United States legislation.
Should you contact us as specified on our "Contact" page or using any other means, your message will be handled by members of the Organizing Team in order to fulfill your request. Besides the message text, this may e.g. involve your name, email address, and message metadata. The legal basis for this are Art. 6 Par. 1 Points (b) and (f) EU-GDPR in combination with our interest to be approachable by participants and the general public.
When contacting us via third-party platforms such as Discord, Twitter, and IRC, what is stated under "Social Media" will apply additionally.
We maintain presences on social media platforms to provide updates on the competition, as well as to stay in contact with participants and the general public. That is our legitimate interest within the meaning of Art. 6 Par. 1 Point (f) EU-GDPR.
Social media platforms are run by third parties. This means we do neither have control over what data they process, nor how they process it. Data may be processed outside of the European Economic Area and the scope of EU-GDPR. That may involve processing for advertising, market research, and profiling.
For details, including opt-out options, refer to the privacy notice of the respective platform. The best way to exercise your legal rights is in direct correspondence with the platform.
We maintain a Discord server. Please note that by design, all messages sent to channels on the aforementioned Discord server are public.
Discord is run by:
444 De Haro Street, Suite 200
San Francisco, CA 94107
We run the Twitter profile @faustctf.
Twitter is run by:
1355 Market Street, Suite 900
San Francisco, CA 94103
We maintain the chat channel
#faustctf on the Freenode IRC network. Please note that by design, all messages sent to this channel are public.
Freenode is run by:

Participants connect to the competition network through a Virtual Private Network (VPN). This section only concerns the VPN connection itself; for data transmitted within the VPN, see "Competition Network".
When joining the network, your IP address is used by our VPN server to establish and maintain the connection. This is necessary to run the competition, therefore Art. 6 Par. 1 Point (b) EU-GDPR applies.
Your IP address and other metadata such as the software client version are stored in logs for error analysis and to enforce the competition's rules. For the same purposes, we also collect statistics on the amount of traffic transferred over the VPN. The legal basis for these operations is our legitimate interest within the meaning of Art. 6 Par. 1 Point (f) EU-GDPR.
Since collection and storage of VPN connection data are necessary to keep the competition fair, you may not object to this processing or demand erasure of the data.
Within the competition network, all communication is based on internal IP addresses from a private range. Each of these addresses is associated with either the Organizing Team's infrastructure or a single team (consisting of an arbitrary number of individuals). Other teams may be able to trace such an address back to your team.
Since FAUST CTF is an IT security competition, services on the competition network deliberately have security vulnerabilities, which may undermine the confidentiality of personal data. The Organizing Team does not control the data processing by services on the competition network, which are run by individual teams, including ones outside of the European Economic Area. If services request personal information, we recommend entering fake data in general.
Our checker scripts regularly connect to services run by individual teams. For establishing and maintaining the connections, they process internal IP addresses. If (real or fake) personal data is contained in the responses from a service, that data may unintentionally get retrieved or stored temporarily. Because this is necessary to run the competition, Art. 6 Par. 1 Point (b) EU-GDPR applies.
We record all network traffic from the competition network for analysis and research purposes. The analysis is necessary to enforce the competition's rules, which is our legitimate interest within the meaning of Art. 6 Par. 1 Point (f) EU-GDPR. As this is necessary to keep the competition fair for everybody, you may not object to this processing or demand erasure of the data.
In the long term, we store the collected traffic for scientific research and may disclose it to third party scientists for this purpose. Research may be performed by ourselves, researchers at the Friedrich-Alexander University Erlangen-Nürnberg, or other scientific researchers. That is based on Art. 6 Par. 1 Point (e) and Art. 89 EU-GDPR. Your right of access, right to rectification, and right to object are limited by Art. 89 Par. 2 EU-GDPR in conjunction with § 27 Par. 2 BDSG. Your right to erasure is limited by Art. 17 Par. 3 Point (d) EU-GDPR.
On the competition network, we also run the service you connect to in order to hand in flag tokens and score points. That service processes your internal IP address to establish and maintain the connection, as well as identifying your team for scoring. This is necessary to run the competition, therefore Art. 6 Par. 1 Point (b) EU-GDPR applies.
Retention Period and Deletion
In general, data are stored as long as necessary for the specified purposes. After that, they get deleted.
In some cases, we are legally required to preserve some data. In those cases, the relevant data will only be deleted after that preservation period has expired. However, data processing will be restricted to the legal requirements.
