One of the most important things parents and caregivers need to understand about today’s digital environment is that some youth and teens are not only highly capable users of technology, they are also highly adaptive. When something is restricted, monitored, or questioned, many youth and teens will look for ways around it. This is not always about deception, often, it is about curiosity, privacy, or simply wanting space that feels like their own. However, it does mean that what a parent or caregiver sees on the surface of a device is not always a complete picture of how that device is being used.
We recently highlighted this reality in an article about platforms like Pinterest or Canva (1). Many parents think of these two platforms as a simple image sharing or inspiration apps, yet they also includes a direct messaging feature. That means a youth or teen can move from browsing content to having private conversations with anyone they connect with, without that shift being obvious to a caregiver. This blending of features is now common across many apps, and it is part of a broader shift where platforms are no longer just one thing, they are ecosystems that include content, communication, and connection all in one place.
Vault APPS
Another layer to this is the use of what are often referred to as “vault apps.” These are applications specifically designed to hide content such as photos, videos, messages, and even other apps. Some of the more popular versions are intentionally disguised to look like something harmless, such as a calculator that can be downloaded in the app stores (2).
On the surface, the app appears to be a basic utility tool. Underneath, it can function as a locked storage space that requires a passcode to access hidden material. For a parent or caregiver casually looking at a device, there may be no obvious indication that anything is being concealed.
Detecting a vault app is not always straightforward, and that’s important to acknowledge right up front. Many of these apps are intentionally designed to blend in or avoid attention. So, this is less about “catching” something and more about understanding what to look for, and how to stay engaged with your child’s onlife world.
One of the first places to start is with the app list itself. On both Apple and Android devices, parents can review all installed apps through the settings, not just what appears on the home screen. This matters because apps can be hidden from view but are still listed in the device’s full application library. If you come across apps that don’t make sense for your child’s age or interests, or that have vague names, that’s worth a closer look.
Another common indicator is duplication, given that some vault apps disguise themselves as tools like calculators, file managers, or photo storage apps. If you notice two calculator apps on the same phone, or multiple apps that appear to do the same thing, that can be a signal to pause and ask questions. The goal here is curiosity, not confrontation. A simple, calm “Hey, I noticed this, can you show me what it does?” often opens more doors than an accusation ever will.
Storage usage can also provide clues. If a device is showing a large amount of storage being used by an app that doesn’t seem like it should require it, such as a “calculator” or “notes” app, that may indicate hidden media files. Photos and videos take up space, even when they are concealed behind a passcode.
Parents and caregivers can also look at app permissions. Vault apps often request access to photos, camera, storage, or files. If an app’s function doesn’t match the permissions it’s asking for, that mismatch is worth exploring. For example, a basic utility app typically doesn’t need full access to a photo library.
SNAPCHAT “FOR MY EYES ONLY”
What makes this even more important to understand is that this type of functionality is not limited to third party apps. Some mainstream platforms have built in features that allow for private storage. For example, Snapchat includes a feature called “For My Eyes Only”(3). This allows users to move photos and videos into a password protected section within the app itself. Once content is placed there, it’s no longer visible in the main camera roll or chat history. Without the passcode, even someone with full access to the phone would not be able to see what has been stored.
Checking for the “For My Eyes Only” feature on Snapchat is a little different than looking for a separate app, because it’s built directly into the platform and designed to be private by default. That means there is no external alert or notification that tells a parent or caregiver it’s being used. However, there are a few practical ways to understand whether it may be active on your child’s account.
The first step is simply knowing where it lives. Within Snapchat, “For My Eyes Only” sits inside the “Memories” section of the application. If your child opens the app, swipes up to access Memories, and you see a tab labeled “For My Eyes Only,” that tells you the feature is enabled. Tapping on it will prompt for a passcode, and if a passcode has been set, that is a clear indication it has been used or at least activated.
It’s also important to understand that this feature does not appear unless it has been set up. So if you see that tab, it didn’t just show up automatically, at some point, a passcode was created and the feature was turned on.
Beyond that, there are some indirect indicators to be aware of. If photos or videos seem to be missing from the main Memories section, or your youth or teen mentions “saving something for later” but you can’t find it in their visible content, it’s possible it has been moved into that locked space. Once content is placed in “For My Eyes Only,” it no longer appears in the regular camera roll within the app.
That said, there are limits to what a parent or caregiver can technically access. Without the passcode, the content inside “For My Eyes Only” cannot be viewed. There is no parental override built into the feature. That’s by design, and it reflects how many platforms are prioritizing user controlled privacy, even for youth and teens.
We suggest that the most effective approach is not trying to bypass the feature, but addressing it directly through conversation. If you notice the feature is enabled, that becomes an opportunity to ask open, non-accusatory questions such as, “I noticed there’s a private section in Snapchat. Can you help me understand how you’re using it?” That kind of approach tends to lead to more honest dialogue than trying to “catch” something.
It can also be helpful to frame the conversation around why features like this exist. Some youth and teens use it for relatively harmless reasons, like saving personal photos they don’t want others scrolling through, while others may use it to hide content they know would raise concern. That difference matters, and you won’t know which it is without a conversation.
APPLE HIDDEN APP FUNCTION
The device itself can also play a role in hiding things from parents and caregivers. Apple’s iOS includes features that allow users to remove apps from the home screen or hide them from immediate view (4). While these tools are often designed with organization and privacy in mind, they can also be used in ways that make it more difficult for a parent or caregiver to fully understand what is installed and being used on a device.
Apple has built a number of features into iOS that allow users to remove apps from the home screen or make them less visible. These tools are not inherently problematic, and were designed for organization and privacy. However, like many features, they can also create blind spots for parents and caregivers who are trying to understand what’s actually on a device.
The first thing to know is that removing an app from the home screen does not delete it. A youth or teen can choose “Remove from Home Screen,” and the app will still be installed, it just won’t be visible when you scroll through the main pages. Because of that, one of the simplest checks a parent can do is swipe to the left to the App Library (the screen at the far right of the device). This view shows all installed apps, even those hidden from the home screen. If something doesn’t appear on the main screen but shows up in the App Library, that tells you it has been intentionally removed from view.
Another useful step is to use the search function. Pull down from the middle of the screen and type the name of an app. Even if it’s hidden from the home screen, it will still appear in search results if it’s installed. This can help surface apps that aren’t immediately visible.
Parents and caregivers can also check the device’s settings. Going into Settings and scrolling through the list of installed apps will show everything currently on the phone. This is often a more complete view than what you see on the home screen. It also allows you to tap into each app and review permissions, notifications, and data usage, which can sometimes provide additional context about how the app is being used.
Screen Time settings can add another layer of visibility. Within Screen Time, parents can see app usage patterns, including apps that may not be visible on the home screen. If an app is showing usage time but you can’t find it on the main screen, that’s a strong indicator it has been hidden from view.
There are also newer privacy features to be aware of. In more recent versions of Apple iOS, users can place apps into a hidden or locked state, sometimes requiring Face ID or a passcode to open them. These apps may not appear in normal browsing and may only be accessible through specific folders or authentication steps. While Apple does not make these completely invisible in system-level views like settings or Screen Time, they can be easy to miss during a quick check of the device.
It’s also worth paying attention to folders. Apps can be grouped together and buried several layers deep inside folders with generic names. This isn’t technically “hiding” in the system sense, but it can have the same effect if a parent is only glancing at the screen.
The takeaway here is not that every youth or teen is intentionally hiding something harmful. It is that the technology they are using has layers, and those layers can create blind spots for even the most attentive parent. This is why relying solely on checking a phone or scanning a home screen is rarely enough.
PREVENTION:
Preventing vault apps or other problematic applications from being installed is not about locking everything down, it’s about putting the right guardrails in place while also building the kind of awareness and relationship that makes those guardrails effective. Technology can help, but it works best when it’s paired with ongoing conversation and clear expectations.
On an iPhone or iPad running iOS, parents can use Screen Time to control app downloads (5). Within Screen Time, you can require approval for any new app installation, which means nothing gets added without a parent being notified. You can also block app deletions. That might seem like a small step, but it prevents a young person from downloading something, using it briefly, and then removing it before a parent ever sees it.
Content restrictions can also be helpful. Apple allows parents to set age based limits on apps, which can filter out some vault style apps or those with hidden messaging features. It’s not perfect, many vault apps are designed to slip past these filters, but it does reduce exposure. Disabling in-app purchases is another useful step, as some apps unlock hidden features after download.
On Android devices, Google Family Link provides similar controls (6). Parents can require approval before apps are downloaded from the Google Play Store, set age restrictions, and even block specific apps altogether. Like Apple’s system, it won’t catch everything, but it creates an important checkpoint before something is installed.
Another often overlooked strategy is controlling how apps are installed in the first place. On Android, parents can disable the ability to install apps from unknown sources, which prevents downloads from outside the official app store. This is important because some vault apps are distributed outside mainstream stores to avoid detection or removal.
That said, here’s the reality we share with parents and caregivers in our presentations. If a youth or teen is highly motivated, there are often ways around most technical controls. They may use a friend’s device, a secondary account, or even web based versions of apps. This is why prevention cannot rely on technology alone.
What tends to be more effective over time is setting clear family expectations around app use. That can include simple agreements like, “No downloading apps without asking first,” or “We review apps together before installing them” via utilizing a “Family Collective Agreement” (7). When those expectations are explained, not just enforced, young people are more likely to understand the “why” behind them.
What tends to make the biggest difference is not control, but connection. When parents understand how these tools work, and pair that knowledge with ongoing, open conversations about privacy, trust, and online behaviour, they are in a far better position to guide their child. Awareness of the technology is the starting point. Relationship and communication are what turn that awareness into meaningful protection.
