WhatsApp amongst other social media platforms is one of the most renowned one. But what you may not know is that it’s also a treasure trove of personal data. From your messages and contacts to your location and online activity, WhatsApp collects a wealth of information about you. And with data breaches and privacy concerns on the rise, it’s important to take a closer look at WhatsApp’s data privacy practices. So let’s dive in, shall we?

What data does WhatsApp collect?

Let’s look at some stats. According to a 2021 study by Statista, WhatsApp has over 2 billion, monthly active users. That’s a whole lot of messages being sent every day to every corner of the world. And every time you send a message on WhatsApp, it’s stored on WhatsApp’s servers. In fact, WhatsApp stores all of your messages until they are delivered to the recipient. And even after they are delivered, the messages are still stored on WhatsApp’s servers for a short period of time.

But it’s not just your messages that WhatsApp is collecting. WhatsApp also collects information about your device, such as your IP address, device type, and operating system. And if you use WhatsApp’s location-sharing feature, it can also collect your precise location data.

How is this data used?

So, why does WhatsApp collect all of this data? According to WhatsApp, it’s to improve the app’s functionality and provide a better user experience. For example, WhatsApp uses your device information to optimize the app’s performance on your specific device. And it uses your location data to provide location-based services, such as finding nearby businesses.

But with all of this data being collected, there are naturally concerned about privacy. In fact, in 2021, WhatsApp was the second-most complained about app in the EU with regards to data protection, according to a report by the European Data Protection Supervisor. And WhatsApp has faced several privacy-related controversies in recent years.
