Frequently Asked Questions
Below you will find a list of frequently asked questions.
Since information about your identity is always separated from information about your purchase and any illnesses, it is not possible to provide individual advice aimed at each individual participant in My Purchases. If, in connection with registration, you have agreed to receive news from the project, you will, however, receive general information and recommendations.
Does participation involve any risks?
The security of your data is important to us. As a consequence, data is stored on secure servers with comprehensive protection against theft and destruction, and which comply with guidelines for the processing or storage of personal information, including logging of access.
Which receipts are collected?
We receive all your receipts from the time you signed up for Storebox, and receive receipts on an ongoing basis until you wish to unsubscribe from My Purchases, or My Purchases has come to an end. Receipts that you upload yourself or have uploaded to Storebox are not included. You must therefore sign up for electronic receipts from Storebox in order to participate.
See the personal data policy from Storebox here.
Why can't you just use anonymous data?
The information is pseudonymised when researchers start their analyses. The pseudonymization ensures that data can still be connected with other data. At the same time, the researchers cannot, based on the pseudonymised information alone, identify the persons who have provided the information or from whom it originates.
Why don't you just ask me what I eat?
Purchase data can be collected automatically over time, without bothering you, and it contains information that is in many ways more accurate than questionnaires. Questionnaires typically take a long time to complete and it is easy to forget small but perhaps significant details. In addition, it can be difficult to remember exactly which products you buy over a long period of time.
What kind of information is obtained from the Danish registries?
Where is my data stored?
When you sign up with MitID, your social security number is stored in a secure database at the Sundhedsdatastyrelsen (Danish Health Data Agency). When the researchers start analysing, data can be uploaded to Statistics Denmark, Forskermaskinen or Computerome (one of Denmark's supercomputers). Here, data will be linked with other data and provided with a serial number, which means that the researchers cannot see your social security number or your contact information.

Why do I have to sign with MitID?
Can the researchers see who I am and what I buy?
Does Storebox have access to my social security number?
Do you give data about me to companies?
Can other researchers access data about me?
Yes, data can be passed on to other researchers if their project has been approved by all relevant bodies and if the project's purpose falls within the overall purpose of the My Purchases project.
