The Robert Koch Institute (RKI) – in its capacity as the central federal institution for public health and as the German national public health institute – publishes the Corona-Warn-App on behalf of the German government The app serves as a digital complement to distancing, hygiene and wearing masks. Additionally, it provides a functionality to add your digital vaccination certificates to prove your vaccination status. It uses Bluetooth technology and the Apple Exposure Notification APIs. The app is designed to help break infection chains by informing you if you were recently close to someone who subsequently tested positive for corona. However, at no time does it collect any personal information. Who you are and where you are remain secret – and your privacy is well-protected.


Exposure logging is the core of the app and should always be active. When enabled, smartphones exchange encrypted random IDs with other devices using Bluetooth.

The random IDs only provide information about the duration and distance of an encounter. No one is able to identify the person behind these IDs. The Corona-Warn-App does not collect any information about the location of the encounter or that of its users.

Based on maximum corona incubation times, the random IDs your smartphone collects are stored in an exposure log for 14 days and then deleted. If a person is diagnosed with corona and chooses to share his/her own smartphone’s random IDs, all persons previously encountered will then be notified anonymously.

No one will know when, where or with whom the exposure event took place. The infected person remains anonymous.

In addition to the exposure notifications, affected users will receive clear recommendations for action. Important: Information about the notified persons is not accessible at any time.


The Corona-Warn-App is designed to be your daily companion, without knowing your identity. This is why the app cannot tell anyone who you are. Data protection is fully guaranteed throughout the app’s entire service life.

• No registration required: No email address and no name need to be submitted.
• No personal information is transmitted: When you encounter another person using the app, your smartphones only exchange random IDs. They measure the time and distance of an encounter, but do not allow to identify persons or find out locations.
• Decentralized storage: Data is stored only on the smartphone itself and deleted after 14 days.
• No third-party access: Neither the person reporting a proven corona infection, nor those who have been notified can be traced – not by the German government, the Robert Koch Institute, any other user, nor by Apple.

This app is not intended for any use outside of Germany. Corona-Warn-App is the main corona app for Germany, where it is interconnected with the national health care system. Despite of the above, Corona-Warn-App is also available in this country. It is provided for anyone living, working, vacationing, or visiting Germany regularly or for an extended period of time.

The terms of use for the Corona-Warn-App apply: By installing and using this app, you accept these terms of use.


Versión 2.23.2

This update includes bug fixes and provides the following new functions:

The validity of vaccination certificates is technically limited to 365 days. However, you can request a new certificate in the app. The renewal can take place 28 days before the end of the validity end and up to 90 days after the end of the validity. In the app you can find a note informing you about the expiry of your certificate.

Very Useful 😊

The App likes to me. I check the incident of the community every day to know how is the situation in the area where lives my family.

The figures are a little bit “nude” without a reference. And the reference is “the number of test” made in the area of reference.

I would like to know how many tests are made at all to get this number of infected.

Tanks. 🙂

Thank you for your suggestion for improvement. We have on GitHub (in English) the so-called Wishlist repository, where similar suggestions for enhancing the app have already been created. See

I have this app in german but I don’t find the option to change from german to english. I’m living in Germany and my friend has the app too but in english. There is an option to change?

Vielen Dank für Ihr Feedback. Die Sprache der App orientiert sich an der Sprache, die in den Systemeinstellungen Ihres Smartphones eingestellt ist. Um die App in deutscher Sprache anzuzeigen, müssen Sie also nur die Spracheinstellung auf Deutsch ändern. Wenn Sie mehr als eine Sprache in den Systemeinstellungen eingestellt haben, dann können Sie die Sprache auch für die App direkt einstellen. Gehen Sie dazu in die Einstellungen und wählen Sie Corona-Warn - Bevorzugte Sprache.

Thank you for your feedback. You will find the print function in the 'Certificates' section of the app as soon as you open the desired certificate and tap on the 3 dots at the top right in the Android app or on 'More' on iOS devices. You can find step-by-step instructions in our FAQ:
