Skald is being evaluated as part of a master's thesis at the Technical University of Denmark (DTU). We process study data to understand how authors use the tool, whether features support narrative design work, and how the evaluation study itself is completed.
Who is responsible for your data
DTU is the data controller for the study. Dual Dagger ApS is the data processor and operates Skald on behalf of the study. Victor Rasmussen is the data protection officer for the study and can be contacted at s204475@dtu.dk.
What we use the data for
- Running the service: account sign-in, saving your projects, and serving the editor
- Thesis analysis: summarising feature usage, editor interactions, evaluation task progress, and survey responses
- Improving Skald during the study: identifying errors and understanding which workflows participants use
- Potential academic reporting: aggregated or anonymised findings in the thesis and related publications
Application data (Hetzner, EU)
Your account details and the narrative content you create in Skald (projects, conversations, characters, variables, lore, and graph data) are stored in our application database on servers operated by Hetzner Online GmbH in the European Union. Dual Dagger ApS has a data processing agreement (DPA) with Hetzner for this hosting.
Evaluation data (PostHog, EU)
After you sign in, Skald records evaluation and usage events through PostHog (for example page views, graph editor actions, evaluation milestones, and in-app survey responses). Skald also records your sessions so that we can see how you use the application, including how you work with narrative content in the editor. Session recordings may include the content shown in the editor, your clicks, navigation, and other interactions with the application.
This data is sent to PostHog's EU cloud (eu.i.posthog.com). Dual Dagger ApS has a DPA with PostHog for this processing.
Analytics and logging are only collected for authenticated users. We do not track anonymous or logged-out sessions.
Legal basis and access
The legal basis for processing your study data is your consent under Article 6(1)(a) of the General Data Protection Regulation (GDPR). Identifiable study data can be accessed by the researcher and by persons who need access to supervise, assess, operate, or protect the study and its systems. Hetzner and PostHog are subprocessors used by Dual Dagger ApS for hosting and evaluation analytics.
Retention and withdrawal
Study data is kept until 31 December 2026. After this date, personal data will be deleted or irreversibly anonymised.
You can withdraw from the study at any time by opening the user menu in the upper-right corner and selecting “Withdraw from study.” Withdrawing will stop further collection, but data collected before you withdrew may still be used for the study. Withdrawing does not affect the lawfulness of processing carried out before your withdrawal.
You can request full deletion of personal data that can still be linked to you by contacting Victor Rasmussen at s204475@dtu.dk. Data that has already been irreversibly anonymised can no longer be linked to you and cannot be deleted in response to a request.
Your data protection rights
Under the GDPR, you may have the right to access your personal data, have inaccurate data corrected, have data deleted, restrict its processing, receive a copy of data you provided, and withdraw your consent. You can exercise these rights by contacting Victor Rasmussen at s204475@dtu.dk.
You also have the right to lodge a complaint with a data protection supervisory authority. You can contact the Danish Data Protection Agency at datatilsynet.dk. If you live in the EU or EEA, you may also be able to contact the supervisory authority in the country where you live or work.
