Inform the participants about experiment context

[2e2a]

• show information about the organisation / individual doing the study
• contact information
• privacy concerns

[gvarab]

Suggestions for the implementation:

• Add a section "Contact and privacy", between "Questionnaires" and "Results".
• Links in this section: "Contact information" and "Privacy statement".
• Contact information: user enters name, contact address (e-mail), affiliation (e.g., university or research institute; optional), optional text field for further details. (Potentially, there could be the option to set one of more contact infos generally in the user profile, and then choose one of them for the study, or provide a different one.)
• Privacy statement: Similar to instructions - mark-down text field. Helptext should contain recommendations for what should be specified here (who has access to the data, how long will it be stored, for what purpose, etc.).
• Contact info + privacy statement will be displayed to participants at the beginning before the experiment. We could automatically add a sentence about L-Rex privacy + contact here as well (specifically for participants).
• Participants can view the contact and privacy info again at any time during the experiment (related to the idea that they can re-view the instructions at any time, see Show rating instructions during the whole trial #15) and return to the experiment.
• No link to the L-Rex main page should be there during participation (perhaps logo without link); see Use different layout for participant views #24.
