Secret Folder App Review: Things Parents May Not Know

Secret Folder App Review

What is a Secret Folder App?

A secret folder app allows you to hide files – like pictures – that you may not want other people to see. They do this by either locking files away behind a password-protected folder or hiding them in an innocuously named folder. As an adult, these could be useful if you want to keep some things hidden from people you might lend your phone to.

There are several apps that allow you to do this, but many of them are taken down quickly – so it makes them even harder to spot.

You can see many examples on the App store – for both Android and iPhone.

Why Do Teens Use Secret Folder Apps?

You might consider yourself to be a fairly strict parent when it comes to social media. If you’re the kind of parent that monitors their teenagers’ phone use, then congratulations: you are doing the right thing by keeping an eye on them. However, teens can use secret folder apps to hide files from their parents that they don’t want them to see.

These apps can look completely innocuous, so you may not even notice them when you’re having a look through your child’s phone. Some of them are disguised as calculators, so if you’re looking in a hurry, you might not even notice them.

As a teenager trying to get around parental restrictions, a secret folder app can be really useful, which is why they’re so popular.

How Can Parents Find Secret Folder Apps?

As you can see, some of these apps are very sophisticated, and they’re great at keeping things hidden. So how can parents find these apps?

Search for Hidden Apps on Appstore

Using your child’s phone, visit the Appstore. Search for any of the following: ‘secret’ ‘secret calculator’ ‘hidden folder’ ‘secret photo’ ‘secret file’. If your child has installed an app with any of these keywords, you’ll be able to tell, as it will say ‘open’ instead of ‘get’. Or, it may say ‘installed’ instead of ‘install’. Here’s an example of an app we have:

And an app we don’t have:

This is one way of finding out if your child has any of these secret apps installed on their phone.

Search for Hidden Folders

Go to whatever photo app your child uses, click ‘albums’, and then make sure you check each folder. If a folder is hidden within another folder, you may be able to find it here. Make sure you check every folder, even ones that are named something innocent (like ‘gaming pics’).

Notice Patterns of Behaviour

You may be able to figure out that your child is hiding something on their phone by their behaviour. Although a lot of teenagers are glued to their phones, you may find that your teen is particularly attached to theirs, and that they don’t tend to leave it lying around for anyone to see. They might jump or cover their screen when you approach them.

You can also tell by their browsing history. If there are big gaps in their internet browsing history, it could be a hint that they’re trying to hide something.

App Block

The App Blocker feature blocks distractive apps at bedtime or study time, or in certain places (like at family events, or at school). Not only will it block your child from using that app, it will also send you a notification when your child tries to use it.

App Usage Report

You can also check your child’s app usage report. This will tell parents how many times an app has been opened and closed each day on a child’s device, and which app is the most frequently used. This can help you to find out if your child is using a hidden folder app.

Screen Time and Smart Schedule

This allows you to block access to all third-party apps (including games and social media apps) with one click. It also allows you to set screen time limits on an hourly basis – helping your child to stick to a reasonable amount of screen time. It will also give you a report on how long your child has been using their device.

The Smart Schedule feature allows you to set screen time limit rules on a timer, as well as a location schedule – this is great for blocking distracting apps, for example, while they’re at school. The child’s live location is updated every time you open the FamiSafe app on your device.

Browser History and Web Filter

The FamiSafe web filtering feature allows you to set pre-filtering rules to block harmful websites based on certain categories (like shopping, gambling, or pornographic websites).

You can also create an additional filtering list, so you can manually block websites yourself.

Finally, you can check your child’s browsing history daily, even if they’re using incognito browsers – this will allow you to truly see what they’ve been looking at online.

If your child has been using a device without these protections in place, then don’t worry – it’s never too late to start. Encourage open dialogue with your child, even if you have to have some difficult conversations, so that they feel they can come to you if they encounter something on the internet that makes them feel uncomfortable.

FamiSafe could help to protect your teen from the dangers of hidden folder apps – so why not give it a try?
