Tell me about some free parental control apps that cannot be deleted. I need suggestions for free parental controls. I do not mind spending time, but first I need to understand how they work and if they can be useful in protecting my children from excessive screen time and adult content.
Okay so this is actually a great question and I wish someone had told me this stuff earlier lol. So basically the apps you are looking for are called “device admin” apps. On Android, when you give an app Device Administrator rights, it literally cannot be uninstalled unless you revoke those rights first. Kids cannot do that without the parent password. Google Family Link is probably the best free one out there. You set it up on your phone, link your kid account, and boom you can see what apps they use, set daily screen time limits, and approve or block app downloads. The cool part is if your kid tries to uninstall it, they just cant. It says something like contact your parent. It works best on Android devices that your kid uses with a Google account. For iPhones, Screen Time built right into iOS settings is the go to. Go to Settings then Screen Time then Use Screen Time Passcode. Lock it with a code your kid does not know and they are stuck. They cannot turn it off, they cannot change settings. Works great honestly. So yes, free options do exist and they do work. You just gotta set them up right 
How to Set Up Google Family Link So Kids Cannot Remove It
Alright let me walk you through this step by step because I did this for my own kids and it was way easier than I expected.
Step 1: Download the Apps
Get Google Family Link for Parents on your phone. Then get Google Family Link for Children on your kid device.
Step 2: Create a Supervised Google Account
During setup it will ask you to create a new Google account for your child. Do not skip this step. This is what makes the whole supervision system work.
Step 3: Link the Devices
Follow the prompts on both phones. You will get a linking code. Enter it on the child device.
Step 4: Lock It Down
Once linked go to the parent app. You can now set:
App approvals so nothing installs without your okay
Daily screen time limits per day
Bedtime locks where the phone goes dark at a set time
Location tracking
Step 5: The Key Part
On the child device go to Settings then Apps then Family Link and you will see the Uninstall button is greyed out. That is it. Done. They literally cannot remove it without going into a whole admin settings that requires your Google password.
This whole setup takes maybe 20 minutes and it is completely free. No subscription, no credit card, nothing 
Reading this thread gives me so much hope honestly 
I have been struggling with my 10 year old being on YouTube until like midnight and I had no idea free solutions like this even existed. I just tried Google Family Link based on what SoloVibe said and oh my god it actually worked. The bedtime feature is the one that got me emotional a little lol. I set it so the phone locks at 9pm and my son literally came to me and was like Dad the phone stopped working. I said yeah buddy thats called bedtime. He was not happy but he went to sleep at a normal time for the first time in weeks. I also want to add something I found while setting it up. There is a setting called App Review where you approve every single app before it downloads. My kid was trying to sneak in some random games and I got a notification asking me to approve it. I clicked No. Simple as that. I know paid apps have more features but if you are tight on budget or just starting out, Family Link is genuinely a solid place to begin. Do not sleep on the free stuff. It can change your family dynamic a lot more than you think 
Few technical things people are missing in this thread. There is a difference between apps that are hard to delete and apps that are truly undeletable. Google Family Link and Apple Screen Time fall into the second category because they are system level or tied to account management. Random third party apps that just say they cannot be deleted are often lying. A determined kid with a YouTube tutorial can remove most of them in 5 minutes.
Here is what makes an app actually stick:
Device Administrator privileges on Android make uninstall require extra steps and a password
MDM profiles (Mobile Device Management) used by schools and businesses are the strongest method
Account based restrictions like Family Link that tie to the account itself not just the device
The weakest ones are just apps with a PIN screen. That is not real protection.
Also one thing nobody mentioned: factory reset. On Android a kid can factory reset the device and wipe everything including the parental app. To prevent this you need to enable Factory Reset Protection by tying the device to your Google account before giving it to your child. That way even after a reset they need your Google credentials to set it up again. That is the real technical layer most parents do not know about 
Xnspy Parental Monitoring App Review
So while everyone is talking about free apps, I want to bring up Xnspy because it covers things the free tools just do not touch.
Yes it is paid. But hear me out.
What Xnspy Does That Free Apps Cannot
Browsing History Monitoring: You get a full log of every website your kid visited, including ones they deleted from their browser. Google Family Link shows you categories but not actual URLs.
Screen Time Reports: Not just limits but actual detailed usage logs showing which app was used and for how long. You get weekly and monthly breakdowns.
Screen Recording: This is the big one. Xnspy can take periodic screenshots of the device so you see exactly what your child is looking at in real time. No other free app does this.
Call and Message Logs: See who your kid is talking to.
Location History: Not just current location but a map trail of where they have been.
Remote Lock: You can lock the device from anywhere.
Bottom Line
If your situation is more serious, like you are worried about online predators or your child talking to strangers, Xnspy gives you a level of detail that free apps simply cannot match. For basic screen time management, free is fine. For deeper monitoring, Xnspy is worth looking into 
Technical Overview: Preventing Parental App Removal on Android
Architecture of Deletion Prevention
Android provides several system level mechanisms that applications can use to resist uninstallation by standard users.
Device Policy Controller (DPC)
Applications that register as a Device Policy Controller through the DevicePolicyManager API gain elevated system privileges. When active, the Android package manager blocks standard uninstallation requests for the registered application. User must first deactivate device admin before removal is possible. This requires navigating to:
Settings > Security > Device Admin Apps > [App Name] > Deactivate
Profile Owner and Device Owner Modes
For MDM grade protection, an app set as Profile Owner or Device Owner cannot be uninstalled through any user facing method. This is the same mechanism used in enterprise environments. Setup typically requires ADB commands or a provisioning QR code during device first boot.
Factory Reset Protection (FRP)
When a Google account is bound to the device before child setup, any factory reset attempt will require that Google account credentials on next boot. This closes the nuclear option of a full device wipe.
Recommended Stack for Maximum Retention
- Bind device to parent Google account
- Enable Family Link with device admin
- Disable Developer Options in settings
- Set a strong screen lock the child does not know
This four layer configuration makes removal practically impossible for a child without physical access to parent credentials. No special hardware required. All features available in stock Android 
Okay I just want to say I came here totally lost and now I feel like I have a whole PhD in parental controls lol 
Like I did not even know Google Family Link existed before this thread. I set it up this morning and my daughter already tried to download TikTok three times and got the waiting for parent approval screen every single time. I felt like a genius honestly.
One thing I will add that nobody else mentioned: talk to your kids too. Like the app is great but my daughter now knows I can see what she is doing and that alone changed her behavior. She asked me why she could not download something and we had a real conversation about it. That would not have happened without the app showing me she tried.
Also for anyone with younger kids, there is also a feature in Family Link called Location Sharing. It shows you exactly where your kid is on a map in real time. I know some people think that is too much but when you have a 9-year-old walking home from school alone, that peace of mind is everything. Totally free, totally works. Try it before spending any money 
Look I am going to push back on something here. Everyone in this thread is talking about apps like they are the solution to parenting and I think that is a problem.
These tools, whether free or paid, work fine technically. Yes Family Link does what it says. Yes Screen Time on iPhone is solid. But here is my issue: what happens when the kid gets a different device? A school tablet? A friend phone? A gaming console with a browser?
You cannot install Family Link on every screen your child will ever touch. So if the only reason your kid is not watching inappropriate content is because of an app on their phone, the moment they get any other device that protection disappears.
Also let me bring up something nobody wants to say: a really motivated teenager will find a way. They will borrow a friends phone, use a VPN, or find whatever workaround is trending on YouTube this week.
I am not saying do not use these apps. I am saying use them as one part of a bigger approach that includes actual conversations with your kids about why certain content is harmful.
The app is a fence. Fences can be climbed. You need to also teach your kid why they should not climb it 
Building on what FixTech said about Factory Reset Protection, there is actually another angle people are missing: Guest Mode and Multiple Users on Android.
If your kid figures out that switching to Guest Mode bypasses Family Link restrictions, they can get around everything. The fix is to go into Settings, then System, then Multiple Users, and disable the option to add users or guests entirely. On some phones this is under Digital Wellbeing or Parental Controls in the main settings.
Also worth knowing: Kids can sometimes bypass screen time limits by changing the device clock manually. Google Family Link protects against this because it syncs with Google servers, not the local device time. So even if your kid sets the clock to noon when it is actually 11pm, Family Link still knows the real time and will enforce bedtime locks correctly.
One more trick: some kids figure out that turning on Airplane Mode can sometimes delay app lock notifications. With Family Link, if the device goes offline, previously set limits still apply locally. The app does not need a live connection to enforce time limits. That was one I had to test myself because I was not sure and it does work offline too 
Case Study: Managing Screen Time for Two Kids With Different Needs
Background: I have two kids. One is 8 and uses an Android tablet mostly for YouTube and games. The other is 14 and has a smartphone for school and socializing.
The Problem
Both were spending way too much time on screens. The 8 year old was staying up watching videos. The 14 year old was on social media instead of doing homework.
Solution for the 8 Year Old
Set up Google Family Link with a hard 2 hour daily limit on entertainment apps. YouTube is categorized under entertainment so it counts toward that limit. After 2 hours, the app simply stops working. Enabled bedtime mode from 8pm to 7am. Zero cost.
Solution for the 14 Year Old
Teenager situations are trickier. Used Apple Screen Time since they have an iPhone. Set downtime from 10pm to 7am. Created an App Limit specifically for social media apps. Added a communication limit so only my contacts can call or message during school hours.
Results After One Month
The 8 year old adjusted within a week. Some tantrums at first but now they actually play outside more.
The 14 year old took longer. There was some pushback. But grades went up after homework time became protected by downtime settings.
Key Takeaway
Different ages need different setups. Free tools handled both cases well without spending anything 
What Research Actually Says About Parental Control Apps and Screen Time
A lot of this thread is based on personal experience which is great. But let me add some context from what researchers have found on this topic.
Do Screen Time Limits Actually Help
Studies consistently show that excessive screen time in children under 12 is linked to sleep disruption, reduced attention span, and lower physical activity levels. Setting limits using tools like parental apps does reduce screen time in most cases when consistently applied.
The Compliance Factor
Research also shows that kids are more likely to follow digital rules they understand. Apps work better when combined with explanation rather than just imposed silently. Kids who know why limits are there tend to self regulate better as they grow older.
App Effectiveness
Platform native tools like Apple Screen Time and Google Family Link have higher retention rates than third party apps because they are harder to remove. This is consistent with what people in this thread have experienced.
Age Considerations
For children under 10, platform controls like Family Link are generally sufficient. For ages 11 to 15 where social dynamics come into play, supplemental tools that include communication monitoring may be more appropriate. For 16 and up, researchers suggest shifting toward trust based approaches rather than hard blocking.
Summary
Free built in tools are backed by evidence for younger children. The tech is one part of a bigger picture that includes communication and trust building 
Jumping in here because I tried a bunch of apps before landing on what works and I can save people some testing time.
Tried: Kids Place (Android) - it creates a launcher that locks kids into approved apps only. Works okay for young kids. But a factory reset removes it completely. If your kid is old enough to google how to reset a phone, this one is not your answer.
Tried: OurPact Free Version - gives you one app blocking schedule per day on the free tier. Very limited but it does work and cannot be easily uninstalled because of how it handles device admin. Paid version unlocks way more scheduling options.
Tried: Bark Free - does not block content, it monitors and alerts you to concerning messages or searches. Different purpose but worth knowing about if you want a light touch approach for older kids.
Tried: Google Family Link - currently using this and it is the one I stuck with. The approval system for apps is really what makes it stand out. Nothing installs without me seeing it first.
Bottom line: there is no single perfect free app. What works depends on your kid age, their device, and how much you want to manage it actively. Family Link is the best all around free option for Android right now in my experience

Bro I literally spent three weeks trying to figure this out and the answer was in my phone the whole time Like Apple Screen Time has been sitting right there in my iPhone settings and I had no idea what it did.
Here is the thing nobody tells you clearly: Screen Time on iPhone is actually really powerful when you use the Family Sharing feature through iCloud. You go to Settings, tap your name at the top, go to Family Sharing, add your child account, and then you can manage their Screen Time remotely from YOUR phone. You do not even need to touch their device after setup.
From your phone you can:
Set their downtime schedule
Set limits on specific apps or categories
Approve or deny screen time extension requests they send you
See a full weekly report of what they used
And the passcode you set to protect Screen Time? It is separate from their device unlock code. So even if they know their own PIN to unlock the phone, they still cannot change Screen Time settings without your passcode.
Oh and one more thing: if your kid tries to just delete the app they are trying to get around, Screen Time can also block app deletion entirely. Go to Content and Privacy Restrictions and turn off Deleting Apps. They literally cannot delete anything without your code. Pretty wild for a built in free tool right 
Are Parental Control Apps Actually Solving the Right Problem
This thread has a lot of useful how to information and I want to zoom out for a second because I think we are missing a bigger conversation.
What These Apps Actually Do
Parental control apps solve an access problem. They limit what a child can reach on a specific device. That is a real and valid thing. Google Family Link and Apple Screen Time do this well and they are free. That part of this discussion is accurate.
What They Do Not Solve
But access is not the only problem. The reason kids stay on screens for hours is not just because they can. It is often because of boredom, social pressure, FOMO, or because screens are genuinely more stimulating than alternatives available to them. An app that locks a phone at 9pm does not address why the kid wanted to be on the phone at 9pm.
The Risk of Over Reliance
When parents rely heavily on technical restrictions, there is a risk of not developing the child internal ability to self regulate. A 16 year old who has had all content filtered their whole life and then gets access to an unrestricted device at college is in a more vulnerable position than someone who was gradually taught to make their own choices.
Final Take
Use the apps. They are useful especially for younger kids. But treat them as training wheels, not as the destination. The goal is eventually a kid who does not need the app because they have built the judgment to decide for themselves 
Okay real talk, can we appreciate how far free tools have come Like five years ago your options were either pay a lot for some sketchy app or just hope your kid was not doing anything weird online.
Now we have got Google Family Link that is genuinely solid, Apple Screen Time built right in, and they actually work without needing a computer science degree to set up.
I want to add something about Chromebooks since I have not seen anyone mention it. If your kid uses a school issued or home Chromebook, Google has something called Family Link for Chromebooks too. Same app, same dashboard. You can set what websites they can visit, block certain categories, and even push Chrome extensions to their device remotely. This is huge because a lot of kids do most of their screen time on a laptop not a phone.
The way it works: supervised Google account on the Chromebook, linked to your Family Link parent account. Same controls as phone. Bedtime mode works on Chromebooks too which I was honestly shocked by. At 9pm the whole laptop just stops working until morning. My kid thought the Chromebook was broken for like two days before figuring out it was me
Point is: the free ecosystem is actually really connected now across devices. One Google account can manage phone and laptop together. That is pretty great for zero dollars.
If you’re searching for a free parental control app that cannot be deleted, it’s important to understand one thing first: no app is truly undeletable. However, you can make a parental control setup extremely hard to remove with the right configuration.
Best free parental control apps (hardest to delete)
• Google Family Link (Android)
Lets you lock app installs, set screen time, and requires the parent’s permission to remove supervision.
• Apple Screen Time (iPhone/iPad)
Built into iOS, it blocks app deletion and changes using a passcode.
How to prevent a child from uninstalling parental control apps
Step 1: Set a strong parent-only passcode (don’t share it)
Step 2: Enable device admin (Android) or Screen Time restrictions (iOS)
Step 3: Disable guest mode and unknown app installs
Step 4: Turn on Factory Reset Protection (FRP) on Android
Step 5: Link the child’s device to your main account (Google/Apple)
Can kids still bypass parental controls?
Yes, in some cases:
- Factory reset (if FRP is not enabled)
- Using another device
- Guessing weak passwords
- Accessing web versions of apps
Free vs Paid parental control apps
Free tools like Family Link and Screen Time are great for basic control, but they don’t offer deep monitoring (like social media tracking or message insights). Paid tools usually add that extra visibility.
If your goal is a parental control app that can’t be deleted easily, your best option is to use built-in tools like Family Link or Screen Time and set them up properly. The strength comes from the configuration, not just the app itself.
TBH, I tried several free parental control apps that cannot be deleted, but most of them didn’t work. I had to do a lot of research and found that most setups fail not because of the app but because of missing configurations. So if you have already gotten an app, here is what you need to care about.
Common reasons kids can uninstall parental control apps
- The app wasn’t given device admin access
- No restrictions were set on app removal
- Guest mode or multiple users were still enabled
- No backup lock (like FRP or Apple ID protection)
- Weak or shared parental passcodes
Even strong tools like Google Family Link or Apple Screen Time can be bypassed if these gaps exist.
How to fix an uninstallable parental control setup
Instead of switching apps, improve your setup:
Lock app deletion permissions inside system settings
Remove secondary users/guest profiles
Enable Factory Reset Protection (Android)
Keep your parent account credentials private
Regularly review device settings (kids test limits over time)
So even the “best free parental control app” won’t work if you’re only relying on the app itself.
What you should look for instead
Rather than asking “which app cannot be deleted?”, ask:
Does it control device-level settings?
Can it restrict account changes?
Does it stay active after restarts or updates?
That’s what actually determines how hard it is to remove. All the best!!!
