Frequently Asked Questions

General Information

What is Yunar?

Yunar is the app that gives you constant access to your loyalty cards. Easily collect points, don't miss out on anything and get the most out of it.

What sets Yunar apart from other loyalty card apps?

We developed Yunar to meet your bonus needs: we support all loyalty programs that you participate in and display your loyalty balance for your preferred loyalty programs. Yunar makes collecting points easy – even if you are at the cash register with five bags in your hands. As a young app, Yunar is just beginning its exciting journey through the world of loyalty programs. First let's focus on the main thing – collecting points. In addition, we offer new useful features for your bonus needs. By the way, if you have a suggestion, feel free to contact us at – we look forward to your feedback!

Is Yunar free to use?

Yunar is completely free for you to use.

In which countries is Yunar available?

Yunar is currently available in Germany, Austria, Spain and France – in the next step, we would also like to offer the app in other countries.

Which operating systems does Yunar support?

Yunar runs on iPhones and Android smartphones. With iOS, we support all versions from 11.0 and later and for Android from version 5.1 and later.

Do I need an Internet connection to use Yunar?

You do not need an Internet connection when shopping to use the loyalty cards that you have saved in Yunar – you can also collect points (or bits, beans, miles, etc.) when you are offline. You do need an Internet connection for other features, such as adding another loyalty card.

Loyalty cards

How do I add a loyalty card without a barcode?

Go to the menu bar at the bottom left and click on the "Loyalty cards" symbol. If you have not yet stored any cards, you will receive the notification that you can add the first card. If you have already stored loyalty cards in the app, click on the "+" symbol. Once you select a loyalty program, the screen for scanning appears – or you can click on "Enter manually" to add a card without a barcode. In the next step, you can enter the card information. Then your newly added card appears in your card overview. You will need the "Enter manually" feature to enter loyalty cards that don't have a barcode or QR code, because these are the only types of cards you can scan.

How do I scan the barcode of my loyalty card?

Select the loyalty card that you would like to add from the offered programs – the barcode scanner will then open. To scan the plastic card, the app requires access to your smartphone camera. If you are storing the first loyalty card or previously denied access to your camera for a different card, the app will ask you for access to the camera. Then please allow the app to access the camera. Hold your plastic card with the barcode or QR code in front of your smartphone's camera. The app will scan the code and create a digital copy of the loyalty card. We can currently only scan barcodes and QR codes – the app cannot yet record digits of the customer number. We're working on that.

How can I add a loyalty card if the barcode scan does not work?

It's easy: you can also enter the card information manually. At the bottom left, click on "Loyalty cards" and then on the "+" symbol to add a card – and then select "Enter manually" and enter the card number.

The scan did not work at the cash register. What can I do?

As soon as you open a card, the screen automatically gets brighter – this happens so that the scanner can read the barcode better. However, some businesses use older models of the scanners. In this case, ask the employee whether he or she can enter the card information manually.

How can I delete a loyalty card?

Go to the menu bar at the bottom left and click on the "Loyalty cards" symbol. This will take you to an overview of all of your loyalty cards. Select the card you would like to delete by clicking on it – at the very bottom you will then see the button to delete the card.

I changed my password for a loyalty program – how can I reconnect it to Yunar?

If you have changed your login data or your password for a loyalty card, Yunar will automatically ask you to enter the login data again.

For which loyalty cards can I view my loyalty balance?

You can currently view your loyalty balance for DeutschlandCard, BahnBonus, Douglas, Esprit, Karstadt and Tchibo. We explain how this works under the question "How can I view the loyalty balance of my loyalty cards?".

Can I synchronize my loyalty cards in the app on several devices?

Yes, you can use Yunar simultaneously on any number of devices and you will always see the same views. You need a user account for this purpose. To do this, go to the bottom right in the menu bar to "Profile" and select "User account." You can create an account under "Register."

Why is my card not detected when scanned at checkout?

Some older card readers are not technically capable of detecting and scanning barcodes and QR codes on smartphone screens. In these cases, the employee at checkout can manually enter the respective code.

How do I add a loyalty card?

Go to the symbol "Loyalty cards" on the bottom left. If you have not stored any loyalty card in the app yet, you will see a note that you can now add the first card. If you have already saved loyalty cards, go to the top right to the "+" symbol and select a loyalty program. At the top, you can choose from the most popular programs or you can search through all loyalty programs alphabetically below. If you change your selection in the country filter, you can also search for cards from other countries and add these. If the program you are looking for is not there, you can still add the loyalty card. Once you have selected a loyalty program, simply scan the barcode of your loyalty card or enter the code manually. Then the newly added card will appear in your overview.

How can I add a card from a different loyalty program?

Go to the bottom left to the "Loyalty cards" symbol and then click on the "+" symbol on the top right. There you will select the view "Search all loyalty programs" and at the top will see a "+" symbol / "Other program" – enter the card here.

Can I add several cards from one provider?

Yes, you can add several cards from a single provider – but you cannot add the same card twice.

User account

Why should I register with Yunar?

By registering, you create a user account at Yunar where your data is securely stored. This is convenient because you can then simply continue to use Yunar without having to re-enter your loyalty cards when you get a new smartphone, for example.

How does the registration with Yunar work?

When you connect one of your loyalty programs to Yunar for the first time, we ask you to register with Yunar. To do this, you just need an email address and a secure password. Once you have entered this information, we will send you a confirmation email that you can use to activate your user account. Then you simply return to the app. In the app, you will automatically receive a welcome message and are directly logged in with your username. If the welcome message does not appear right away in the app, you can log in under "Profile" under "User account" with your email address and password. By the way: Yunar has initially and fully integrated the European General Data Protection Regulation (GDPR) into its services. We save all data within the EU and also protect it with IT security procedures that meet the highest technical requirements and standards.

The main purpose for Yunar is to help you collect points and save. In this context, we save the following data about you, among other types of data: · Data that we receive from your app store (e.g. general information about your end device) · Data that gives you access to our app (e.g. nickname, password, email address) · The loyalty cards you recorded (e.g. card number, loyalty card provider) · Statistical information about the use of the app (e.g. number of cards stored, location, clicks on advertisements)

Is my data secure with Yunar?

Executive summary:

Yes, your data is secure with us. We know your concerns about data security and we take that very seriously. We comply with the requirements of the General Data Protection Regulation, which have been adopted by the legislator in order to protect data in a specific manner. We use the latest encryption methods for this purpose. In addition, we only use the data that we really need to be able to provide you with our services.

Long version:

Data protection and information security were already a top priority when designing our IT architecture. We have implemented both technical and organisational measures to meet the requirements of the DSGVO and at the same time to mitigate the risk of compromising your and our data appropriately.

Technical measures include, for example, the encryption of data streams and data storage, the sealing off of our services to prevent unauthorized access or the automated monitoring of our IT infrastructure to detect and respond to abnormalities.

The organizational measures include, for example, the introduction of a comprehensive information security management system that provides technical and organizational specifications based on the ISO 2700x standards. The TLS procedures 1.2 and 1.3 have been activated and our systems have been optimised according to the latest standards.

All your stored data is encrypted multiple times, especially extra sensitive data like the details of your cards. In addition, we have appointed an information security officer and a data protection officer, who each carry out regular checks and ensure that the guidelines are observed.
