About this app

Many coronavirus restrictions have been lifted. As a result, the CoronaMelder-app has lost much of its usefulness. The app is therefore no longer active, although it can still be downloaded. This means that the app does not track encounters with other people. You will also not receive a notification after you have been near someone with corona. Should a new variant of the coronavirus emerge in the future and make an alert system necessary, CoronaMelder may be reactivated.

CoronaMelder is the official Dutch coronavirus notification app, developed under supervision by the Ministry of Health, Welfare and Sport. The app digitally helps the Municipal Public Health Service’s (GGD) with their source and contact research.

The app warns you after you’ve been near someone who has coronavirus. That way, you can protect yourself and the people around you. And we can keep the number of infections in The Netherlands as low as possible. Using this app is voluntary. No one is allowed to check whether you’ve got the app on your phone. But the more people use the app, the better it works.

During the development of this app, we took accessibility into account. See our accessibility statement for more information.

How does the app work?

#You only give access to your Bluetooth data

CoronaMelder uses Bluetooth to see when you’re near other people who have the app. The app doesn’t use any personal or location data. So the app doesn’t know who you are, where you’ve been or who you’ve encountered.

#You get a notification after you’ve experienced a higher risk of infection

The app sends you a notification when you've been near someone for at least 15 minutes who later turns out to have corona. That person must be using the app as well.

#You can warn others if you turn out to be infected yourself

Were you tested by the GGD and found to have coronavirus? Then, together with the GGD, you can use the app to send a notification to people who were near you during the period you were contagious. This notification only tells them when they were near an infected person. Not that you were this infected person, or when they were near you.

How does the app handle your data?

• You don’t have to enter personal data like your name or email address.
• When you encounter another person, your phones use Bluetooth to exchange random codes. This is how the app calculates the duration of the encounter, and your distance from the other person. The codes don’t include any information about who you are and where you’ve been.
• The codes you exchange through Bluetooth are only saved on your phone and automatically deleted after 14 days.
• App users cannot be traced by the app's developers, the government or other app users.

Generally works well. It works so quietly I sometimes wonder if it's working well. Only once had a notification, luckily I should say. The toggle to force Dutch on an English phone doesn't work, it remains in English.

Works fine for me. However, I was wondering if there could be a "pauze" button in it. For example, when I go to the gym I leave my phone in a locker. It would be great if I could pauze the app for, let's say, two hours. And after two hours is turns itself on again (starts recoding again) so that I do not forget. This, I suspect, will increase the accuracy of the app and I guess it is very simple to implement.

Installed awaiting the dwelling delay on roll-out, but noticed that the notification information (on non-exposures, touch points, check moments, etc.) only appears in the notification and cannot be looked-up in the app anymore. Not sure whether to retain as I have a bad habit of accidentally swiping away notifications ;-)... Room for improvement I guess for the devs (this also shows a bit on what the app is actually doing, hence potentially taking away some concerns when available in the app).
