Together we get the coronavirus in Netherlands under control!
Do you want to help us?
The COVID Radar app was developed by the Leiden University Medical Center (LUMC). The goal of the COVID Radar is to support scientific research. All data is treated confidentially. The data is stored securely in the Netherlands. Read more about this in the disclaimer. This app is not intended to provide you with medical advice. If you would like personal medical advice based on your complaints, please consult www.thuisarts.nl, the RIVM website, or contact your doctor.
In the Netherlands, there is so far limited testing whether people have the coronavirus or not. A person is only tested if he / she has symptoms, is hospitalized, belongs to a vulnerable target group, or works in the healthcare sector himself. As a result, we do not yet know exactly how many people in the Netherlands are infected with the virus.
By collecting data on complaints from as many people in the Netherlands as possible, we can investigate how many people have (had) the corona virus and where they reside in the Netherlands.
With this data we try to predict who is at great risk and who will be less and what the expected care demand will be: how many corona patients do we expect where and when?
Your contribution to this research is very important to arrive at population-oriented advice and to predict the need for care.
No. This is a non-profit initiative. The app is and remains free. And any data you provide will not be used for commercial purposes.
No, this app is intended to support scientific research. Be sure to follow the guidelines of the appropriate authorities (www.rivm.nl or www.thuisarts.nl) if you have medical questions or need help and if in doubt, contact your doctor in time.
Self-checkers are also available, for example: saltrodirectlab.nl/corona/corona-testwijzer
Three different types of apps can be distinguished:
App for scientific research: the LUMC COVID Radar app falls under this category. The app collects data to carry out scientific research into the development of the corona virus. It is desirable for this research that the user provides his or her answers every day. The research is on a population level and not on an individual.
App for medical advice: the OLVG app falls under this category. This app is intended to provide medical advice, if necessary to link the user to a doctor or general practitioner, and to continue to support communication between the user and the doctor when COVID-19 is involved.
App for tracing: these types of apps are not yet in use in the Netherlands. These apps track where the user has been and who they have been around. In many countries, a GPS-based trace solution is in use. In the Netherlands, this clashes with privacy legislation. Alternatives that offer better protection in the context of privacy are being investigated.
RIVM only shows the complaints. The LUMC Radar also shows how we behave, the social distancing.
The people affiliated with the RIVM Radar send their answers once a week. The LUMC app asks the user (preferably) to send their answers daily
RIVM does not hire new participants on this moment. The LUMC would like to reach everyone in the Netherlands with this app, to collect as much data as possible. The more data, the more reliable the results of the study.
RIVM has a website where the radar can be viewed. The LUMC Radar is in the app on the mobile phone. This means that the LUMC Radar is always at hand.
The government is investigating various apps with different functionalities. Whether the functionality that the COVID Radar offers can play a role in this is ultimately up to the government. Here, the government will make an informed decision in the short term.
THe initiative is now very large. Since the launch, there are more than 200.000 participants. Together they sent in over 1.2 million measurements. What is really going to be of value is that users fill it in the COVID Radar for a longer period of time. In this way, we will be able to measure whether and how government policy will influence the symptoms that users report in the near future.
No, there is not at the moment. The goal of the COVID Radar is to collect as much data as possible every day. This is important to properly investigate the course of symptoms and behavior. To make this as easy as possible, an app was chosen on the mobile phone.
The data collected is used for scientific research in the context of the fight against coronavirus (COVID-19). Only government medical authorities and academic research centers may use the data. For extra information, you can read the privacy statement on the website.
All data is treated confidentially. The processing of the data takes place in accordance with the privacy and security standards that apply to this app. The data is stored securely in the Netherlands and stored for a maximum of 5 years. Please note that data may also temporarily remain in the history (web cache) of your phone or tablet. Your device's operating system will automatically remove this.
You send an email to firstname.lastname@example.org with the following information:
- The numbers of your zipcode (for example: 1234)
- The timestamp of your most recent measurement (for example: 30-04-2020 08:23:56). You can find this information by clicking on the small house, and scrolling down on the homepage.
With this information, we can find you as a user in the database.
We are aware of this, but unfortunately this is something we cannot do anything about. This has to do with the search functions of Apple and Google. They are reluctant to display corona-related apps. To make downloading the app as easy as possible, we put the download link on the homepage of the website.
Only the following data is stored each time you send the questionnaire:
- Age category (no specific age or date of birth)
- Numbers of your postcode (Note: to guarantee your privacy, postcode areas with less than 200 households are excluded from the analysis)
- Your gender
- Do you work in healthcare? (Yes or no)
- The answers to the 15 questions in the questionnaire
No other information is collected. So also not your name.
The data is stored for 5 years because then it can be used for a longer period of time.
Yes it has been approved. Not by the medical ethics committee, but by a Science committee. This is the committee that decides on this type of research. For more information about this, please visit this page on our website: https://www.lumc.nl/org/metc/wetgeving/WMO-criteria/
No, the COVID Radar is now only available for Android 6.0 and iOS 11.0 and higher. This is the vast majority of Dutch users at the moment.
We quickly released our app with default app permissions settings. Some of the things we ask permission for are definitely needed. Some don't, but we don't use these either. We will remove these permissions with subsequent app updates.
No, because we wanted to roll out the app quickly, this is not there. We will include the suggestion as a possible addition in a future version of the app.
Please take measurements regularly, preferably daily. In this way, data is properly collected for the study.
We receive many suggestions for additional questions, improvements and expansion of the functionality for which we thank you. We include all feedback and suggestions, for example for a possible addition in a future version of the app.
Based on the language choice of your mobile device, Dutch or English is automatically selected. As a user you cannot change this yourself at this time.
No, you cannot edit your profile. However, you can delete your profile and create a new person with the correct information.
Yes, this is possible in the home screen. Click on the house to go to the home screen.
No that is not possible. The app works on the basis of Dutch postcodes. Information from abroad cannot be processed via this app.
You can enter the data for yourself and all your housemates in the app. You create a separate profile for each person in your house. Click on the homepage to add a person. It is not necessary to add roommates who themselves share their data via another mobile device.
No, this is not (yet) possible. We wanted to make the app available as soon as possible with the first questions. We will include this as a possible addition in a future version of the app.
Yes that's right. The data of all persons is then sent. The data that was sent last is saved per day. So it doesn't matter if you send the data several times a day.
Yes, you can still complete the app. This is valuable for the research. We also continuously check whether it is necessary to complete the questionnaire in order to achieve better results.
This is not possible at the moment. We ask you to participate and share your data via the app. In order for the research to be successful, it is important to collect data about the symptoms and behavior of a large groups of participants. It is also the sharing of your data that shows the complete picture, for which we thank you.
Thank you very much for your input. You can send your suggestion or feedback by email to email@example.com. We include every suggestion as a possible addition in a future version of the app. In addition, we continuously examine whether it is necessary to adjust the questionnaire to achieve better results.
Yes, you can still complete the questionnaire. Please fill in the highest number possible. This is valuable for the research. For example, if more than 20 people came within 1.5 meters, enter 20. In addition, we continuously examine whether it is necessary to supplement or adjust the questionnaire to achieve better results.
Before we launched the app, we have made the best estimate possible. LUMC researchers have done this in collaboration with data scientists. Now that the app is live and data is being collected, it is periodically monitored whether the algorithms behind the Radar need to be adjusted to give the correct image. If an adjustment is made, it will be clearly communicated to the users.
With the COVID Radar app the LUMC collections data about your health and behaviour. With this data we want to get a better overview of the spread of the coronavirus (COVID-19).

Your contribution to this research is very important to arrive at population-oriented advice and to predict the need for care. Do you have any questions about the app?
