What do dating apps know about us?
Online dating apps are very popular. It is easy to install them on any device and to access them at any time from any place. They are fun and sexy and give lots of hope to those who are searching for their perfect match. But what really happens when someone installs an online dating app on their smartphone?
We did a study of user permissions to online dating apps allowing access to their personal data such as identity, photos, contacts or network access on their smartphones.
The results show that when installing one of the examined dating apps, users give access permission for a lot of personal data on their smartphones, like precise location, other accounts on their device, network connections, modification or deletion of the contents on their USB storage and much more.
The goal of Datingroo’s research is to raise awareness and provide a better understanding of what data and information online dating apps can access on a user’s device.
Let’s take a closer look.
Summary of research
Our study is based on the data collected from the 10 most popular online dating apps for Android systems. We investigated what concrete informations and smartphone data those apps have access to once they are installed.
The analysis focuses on apps available in the Google Play app store in July 2019 and examined 45 personal data access points in 13 categories.
The main conclusion of the Datingroo research
Although the primary goal of an online dating app is to connect users and not to protect them from cybercrime, the actual fact is that hackers are able to access informations easily by looking into the device directly through the app. When installing an online dating app, users are instantly giving permission for access to a lot of personal data, and many app users are not even aware of those permissions or how they could be misused.

We examined the 10 most popular online dating apps:

DEVICE & APP HISTORY
- Retrieve running apps
Among all tested online dating apps, Badoo and Plenty of Fish have access to most of the data in users devices (92%). Having in mind that those two are the most popular online dating platforms with more than 522 Million users worldwide together, this data access provides them an enormous amount of personal informations.
Coffee meets Bagel has the least data access, as well as the fewest users among all tested dating platforms (7 Million users).
OkCupid, with 50 Million users worldwide, is at the bottom of the list for data access on users mobile devices. Other very popular dating websites such as Tinder, Loovo, eHarmony, and Zoosk have similar levels of access to data on a user’s device.
What can go wrong?
Since our study showed that almost all tested online dating apps have access to users storage, photos, media, files, location, contacts, and full network access, our research goes deeper into the topic in order to understand the negative effects that can happen in case of data leaks from the device that the application has access to.
Through vulnerability of the online dating apps, an attacker could steal the user’s saved billing information on their device and could use them to make unauthorised purchases.
Since all researched online dating apps have access to the photos, media and files, an attacker could use some confidential business proposals and contracts or some compromising photos and videos of the user and use them for criminal purposes.
One extremely personal privacy violation when an app has access to the camera would be if an attacker takes control of the camera on the user’s device and takes unauthorised photos and videos of the user when they are not aware of it.
If an attacker has access to the contacts from a device, they could send out messages with malicious code pretending to be the user. This could potentially infect the devices of the user’s contacts .
By having access to the user’s location, an attacker could know how the user moves, where they sleep, where they work, and their daily routine. Using GPS data, an attacker could track the user and physically approach them.
An attacker could modify data and information stored on the applications. An attacker could also deny user access to the application.
What users can do to protect themselves
When a user installs an online dating app and gives all the permissions for accessing the data from their device, they expose their data and should be always aware of it. In spite of this, there are still a few ways users can protect their data and have control over it.
- Create a strong password for each online account. The best way to create a password is to choose three random words that are not related to any of your personal information, hobbies, sports teams, place of birth or family members. Always have in mind that email and online banking accounts are highly important and should have extra strong passwords.
- Don’t divulge personal information such as your birthday, work, salary, social media profiles, home address, bank account, children, calendar, etc.
- Keep important information, documents, passwords, photos, business contracts and explicit videos and photos out of your mobile device. Store them on a device not connected to the internet.
- Check your mobile apps and the access they are granted regularly. It can happen that an app gains additional permissions on your device each time it updates. If you notice something alarming, unclick it or reinstall the app.
