Your partner can only see the answers, which you have in common, i.e. all your matches.

So if you like a fantasy and your partner does not, he/she will not find out about it.

We realize that sexual fantasies are a very sensitive topic. As a result, you do not need to register and you connect to your partner anonymously via randomly generated codes. So you always stay anonymous when using UnderCovers.

If you have more specific questions, feel free to check our privacy policy:

If there are any questions left, you can send an e-mail to:

After you finished the tutorial, you can see a big red button at the bottom of your screen. Just click on it and follow the instructions.

The basis idea is as follows:
We generate a code for you, e.g. 1234ABCD
When your partner enters this code, we know that your device and your partner's device belong together without us knowing your name, e-mail adress oder telephone number.

We still have an old version of UnderCovers online. However, it isn't compatible with the Android version. You can find it here:

We are currently developing an iOS version and hope to release it at the end of the year.

Unfortunately not (yet!). We want to give every couple the same great experience with our app. This also means that we would like to adjust the content to fit homosexual couples perfectly. However, we are currently lacking the resources to do this.

Both of you get individual content, depending on your gender and your “like”-indications. However, if your partner likes a certain item it becomes more possible for you to see this item in your screen as well.

In total, we have 9 different types of content. Each of them has a different colour in order to help you see clearly. They function as an orientation throughout UnderCovers.

Pink: Fantasies you might like
Grey-blue: Sex toys you can try together
Turquoise: (Unusual) places to have sex at
Yellow: positions that help you to break the routine

Orange: Scenarios that help you to realize your matches
Plain blue: Tutorials that show and explain the technical details of your matches
Dark blue: Articles related to sex, love and relationships. Here, you can also find our column
Purple: Tips that should make your love life more exciting, more entertaining and safer
Green: Fun facts that hopefully will make you laugh
