All data collected as part of this study are stored at the University of Luxembourg only and not shared with third parties.
When you join the study, you will be asked to fill in a short socio-demographic survey. This helps us understand the study population.
During the study you are anonymous. We cannot trace back any browsing or purchasing activities back to you. The app data collection tool collects browsing and scanning data anonymously. Under the tab “Profile” in the App, you will find a link to an anonymous user survey asking you a few short feedback questions about the App. The survey will only take 5 to 10 minutes of your time and your answers will allow the research team to assess the usefulness of the App.
The first time you use the App you will be asked to respond to a few short questions about your food shopping preferences. This helps us set up the App to your needs. These questions will only be asked once and not be shown again in subsequent visits.
No personal information is collected by the App, you are anonymous during the entire study. We cannot trace back any browsing or purchasing activities back to you. The app data collection tool collects browsing and scanning data anonymously. The sociodemographic survey we have designed is also anonymous. The user survey (you find the link under the tab “Profile” in the App) asking you a few short feedback questions about the App, is also completely anonymous.
Goodness Groceries will contains a selection of products from Pall Center. These products are marked by a flyer with a QR code in-store. You will be able to scan this QR code using the app to see product information.
Each product supplier has agreed to take part in the study and has provided detailed product information on how the product meets sustainability indicators for each category. For more about information see the definitions.
For each product there will also be a longer version of the product information which will sit on this website. This allows anyone who is interested to see the full product information.
We may add new products to the App throughout the course of the study. If new products are added you will see an update available in the App Store or Google Play.
You can browse or scan a product’s QR code in the shop to see product specific information.
You can use the compare function to compare any of the same products that exists in different categories (e.g. local conventional flour, local organic flour, imported organic flour).
You can browse all product information anywhere and anytime and at your own pace.
Under the tab “Profile” in the App, you will find a link to a short anonymous user survey asking you a few feedback questions about the App. The survey will only take 5 to 10 minutes of your time and your answers will allow the research team to assess the usefulness of the App.
We are undertaking this study because we are keen to understand which areas of sustainability consumers in Luxembourg are interested in when it comes to food shopping, why they purchase certain products, and if providing sustainable product information to consumers via an app is helpful in making more informed choice when shopping.
Your information is valuable to us. Participation in academic studies can provide valuable research data in understanding which sustainability indicators are of importance to people and how technology can help people when making decisions about food. It can help to detect barriers that prevent consumers to make more sustainable food choices.
After the study, the collected data will be analysed and the results will be used academically, published as well as made accessible to decision-makers and the public. It will also stimulate further research.
You can leave the study at any point by contacting us or by uninstalling the App from your phone.
You do not need to provide a reason why you are leaving the study.
All the data you provided will be deleted once you leave the study.
