What Is a Spy App?

Spy application, or spyware, is one of the most common types of software designed to collect unauthorized data from a user’s device. Most of these programs are legal and are available in the official app stores. Their goal is to track the location, browser history, calls, etc. As a rule, spyware can cause leakage of confidential data and violation of privacy.

What Are The Types of Spyware?


Tracking programs, or trackers, collect data from the device and forward it to third parties. It shares your location, browsing history, documents, contact lists, and frequently visited websites. Often, trackers are used by managing directors to monitor employees and parents to control their children. Of course, they are also popular with fraudsters and cybercriminals. Trackers can be integrated into browsers’ toolbars produced by search engines and large Internet portals.


Keyloggers are special programs that record keystrokes on the target device’s keyboard. With its help, third parties can get user’s credentials, bank card data, or any other information.

Both trackers and keyloggers can be installed on a smartphone, laptop, and other gadgets. Their purpose is the unauthorized collection of information from the device. Quite often, spyware is used to collect marketing information and profile users for targeted ad serving. Did you spend a couple of hours on the Nike website? Then you will definitely get an ad suggesting you a pair of Air Max on Instagram!

What Features Do The Spy Apps Have?⚡

There is a basic set of functions that all spyware programs have. It includes:

– Audio recording of phone conversations. Hence, all calls from the target device begin to be tracked in your account.

– Tracking incoming and outgoing messages. Text messages are saved on the server in the same way as conversations are saved.

– Determining the location of the end-user. The app receives the location and sends it to the Internet server with a set frequency.

The extended list of functions includes:

– A voice recorder. This function allows you to record the sound of the phone’s environment.

– Application control. So, you can track all the data from messengers, mailbox, and Internet browsers.

– Access to multimedia. You can manage photo and video files from a controlled device.

– Remote control. This feature allows you to block various programs, manage settings, and so on.

– A keylogger. Thanks to this function, you can receive the user’s username and password, the texts of sent messages, etc.

Of course, this is not a complete list. It is worth noting that often not all the features available on Android devices also work on iOS.

How to Prevent Spy App Installation?⚙

Spying apps are dangerous for privacy. Numerous utilities can be found in the public domain and the official app stores. The OS, browsers, and hardware have built-in and enabled spyware by default, which is secret for ordinary users. To protect yourself from spyware, you need to perform 7 simple actions:

?Install a firewall and monitor the network activity of installed programs.

?Check the privacy settings of your device and browsers. Do not forget to disable unnecessary functions. 

?Block the installation of third-party applications. Often, spyware leaks into the smartphone with the owner’s permission, along with other applications. With the help of your phone settings, you can protect yourself from these unwelcome programs. 

?Periodically view the list of installed programs and delete unidentified or rarely used ones. Most often, spyware gets into the smartphone when installed through the browser. If you use the official Play Market and AppStore apps, the risk is reduced significantly. 

?Set a strong password. No matter how many gadgets and software developers warn, most users are extremely careless. Typical passwords such as `1234`, the year of birth, or the nickname of your cat don’t work out. Use them once, and grant the money earned the hard way to hackers. Password security is achieved by using not only a combination of letters but also numbers and characters. Of course, you can try a complex password, like DkG#n1*7M<pY. However, it is impossible to remember it. Storying it on the smartphone would also be a huge mistake. A good password generator can come in handy. As a last resort, we recommend that you write down usernames and passwords on a piece of paper and store it in a highly secured place. 

?Do not disable the phone lock! Lock your devices, especially if you are in a public place, for example, in the office. Also, the phone lock might be helpful if you tend to forget your stuff in a taxi, at a party, or behind the bar. The disabled lock allows everyone to instantly copy all the information stored in the gadget’s memory. Messages, passwords, search requests, photos, and videos-everything will leak into the wrong hands.

?Download the antivirus to protect your smartphone. As soon as new viruses and spy apps appear, programmers puzzle over the antidote. There are numerous harmful programs, but installing a good antivirus can sort out a problem quickly. However, some people are not satisfied with such programs as they slow down the operation of the device.

So many people live their lives on their phones, storing their personal information and recording almost everything they do, that cell phones have now become a prime target for spying software.”
