    Whatsapp Spy App - how does it work?

    How mspy worksThere are many spy apps. The principle behind all WhatsApp spy apps is relatively similar. The spy app is installed and activated on the target device to gain access to WhatsApp messages, photos and videos. It runs hidden and invisible in the background. The best WhatsApp spy apps don't even have to be installed on the phone anymore. With iPhones, access to the target's iCloud account is sometimes sufficient.

    The best WhatsApp spy apps are so well camouflaged that the owners have no way of recognizing that a spy app is installed on the cell phone.

    Does a WhatsApp spy app work on all phones?

    A spy app works on all common Android and iOS phones and tablets. However, there are some significant differences between the two operating systems.

    iPhone cell phoneWhatsApp Spy Apps for iOS

    You don't even need access to the target device for the basic functions of a spy app on iOS. All you need is the spy app and iCloud credentials of your target. To monitor calls and multimedia files, however, you have to perform a so-called jailbreak before installing a spy app.

    WhatsApp Spy Apps for Android

    For basic spy functions, such as reading WhatsApp messages on Android phones, you only have to install the WhatsApp spy app. In the case of more complex monitoring, such as tracking calls or viewing media files, however, a root of the target device is necessary.

    Why should I use a WhatsApp spy app?

    There are many reasons to use a WhatsApp spy app. Do you think your kids are using WhatsApp to hide conversations with questionable or even dangerous people? As an employer, do you suspect that your employees are not productive in their working hours or that they may even intend to disclose company secrets? Maybe you are just afraid that your partner is unfaithful to you and uses WhatsApp for it.

    So a WhatsApp spy app can be a helpful tool to protect children, company or relationship from danger.

    Are WhatsApp Spy Apps Legal?

    legally illegalUsing smartphone spy apps to supervise children is legal without their knowledge. In adults, however, the whole thing looks different. It is illegal in Germany to install a spy app without the knowledge of the cell phone owner. If you want to use a spy app to monitor your life partner or employee, you have to inform them beforehand. If you don't do this, you are making yourself liable to prosecution. In Germany, illegal surveillance of cell phones can result in prison sentences of up to 2 years.

    Spy apps can save lives

    The most common use of spy apps is to monitor children. Since this is legally allowed as long as the children are not yet legally competent, you do not have to worry about any legal problems. In fact, in our research on spy apps, we came across a terrifying statistic: Only every 10th victim of cyber bullying confides in their parents. Bullying victims are generally considered to be at greater risk of suicide. So, if you are concerned about your child being bullied at school but not confiding in you, a WhatsApp spy app can be very useful.

    A WhatsApp spy app can also help if you suspect that your child is talking to untrustworthy people via WhatsApp and is possibly putting themselves in danger.

    Responsible use of WhatsApp spy apps

    bullying victimWe understand that it is perfectly normal to worry about your children. However, too much control usually leads to more problems and mistrust. Responsible use of spy apps can therefore mean, for example, that you do not read all of your children’s WhatsApp messages, but only those that you think pose a serious threat.

    It may also be worth considering telling your child that an “emergency assistant” is installed on the cell phone. For some children, it can even provide a sense of security that you, as a parent, are able to help in an emergency.

    Trusted WhatsApp spy app provider

    A spy app gives you access to the most private glimpses into a person's life. Therefore, you should be extra sure to only use trustworthy providers and not entrust these private insights to shady people.
