I wanted to use Pingo for tracking my children but I am scared because I do not want their privacy to be compromised. People I need understanding.
Using Google Family Link for Transparent Child Monitoring
What Actually Happens With Pingo
Okay so I had the same worry when I first started looking into this stuff. Let me break it down for you in plain English.
Pingo does show activity data like location and app usage to the parent account. But here is the thing that a lot of posts do not tell you: whether the child sees a notification depends entirely on how the app works. On Android, a small icon usually appears in the notification bar. iPhones handle it differently.
A Better Option: Google Family Link
Since you are already worried about privacy, let me walk you through Google Family Link instead. It is transparent by design, which means your child knows they are being monitored.
Setup
-Download Google Family Link on your phone from the Play Store.
-Create a Google account for your child if they do not already have one.
-Open the app, tap “Get Started” and follow the prompts to link your account as the parent.
-On your child’s device, install the Family Link app and sign in with their account.
-Accept the supervision request on your parent device.
-Go to settings and configure screen time limits, app permissions, and location sharing.
Why Transparency Is Actually the Better Move
Here is something worth thinking about. Kids who know they are being watched and understand why tend to build better digital habits than kids who find out later they were being monitored secretly. The trust factor is real. 
You can still see their location in real time, get weekly activity reports, and approve app downloads. All of that, without the sneaky feeling.
@StackExplorer honestly the privacy concern you have is so valid and I respect that you are asking before just downloading something 
most parents just install whatever app shows up first in Google and do not stop to think about what it actually does. so good on you.
to answer your main question: Pingo does collect location data and some usage info. on Android devices running recent versions, there is usually some kind of system notification that appears. it is not completely invisible. on older phones or certain custom Android builds, the notification can be suppressed more easily, but that is becoming less common.
if your main goal is knowing where your kids are, plain old Google Maps location sharing is free, works great, and your kid can see exactly that you are sharing locations with each other. no mystery, no drama.
my kids actually prefer that setup because it goes both ways. they can see where I am too lol. made car pickups so much easier 
Setting Up Apple Screen Time for iPhone Kids
Why I Stopped Worrying and Just Used the Built-In Stuff
So I went through this exact rabbit hole about two years ago. Tried three different third party apps before realizing Apple already built what I needed right into the phone. If your kid has an iPhone, this is genuinely the easiest path.
Full Setup Guide
Before You Start
Make sure you have set up Family Sharing on your Apple ID. This is the foundation everything else builds on. Go to Settings, tap your name, then Family Sharing.
Add Your Child to Family Sharing
Open Settings on your phone. Tap your name at the top. Select Family Sharing and then Add Family Member. Choose Create Child Account and follow the steps.
Enable Screen Time on Child’s Device
On your child’s iPhone go to Settings. Scroll down and tap Screen Time. Tap Turn On Screen Time. Select This is My Child’s iPhone.
Set a Screen Time Passcode
This is important. Set a passcode that only you know so your child cannot change the settings themselves. You will be asked to set this during setup.
Configure Communication Limits
Under Screen Time tap Communication Limits. You can set who they can talk to during school hours and after bedtime separately. Really useful feature.
Enable Location Sharing
Go back to Family Sharing settings on your phone. Turn on Location Sharing. Your child will see a notification that location is being shared, which is the right way to do this.
Review the Reports
Every week Apple sends you a summary. You can also check anytime by opening Screen Time from your phone and selecting your child’s name.
One Thing Worth Knowing
Your child will see that Screen Time is active. That is by design. Apple made this tool to be a family conversation starter, not a surveillance system. And in my experience, that framing works a lot better long term. My 13 year old actually reminds herself when she is getting close to her limit now. 
No creeping around required.
quick technical note for anyone reading this thread 
the question of whether an app is “visible” to the child device is actually a system permission question more than an app design question.
on Android, any app that accesses location in the background must declare that permission explicitly, and since Android 10, the system shows an indicator when location is being accessed. you can verify what permissions Pingo or any app is using by going to Settings > Privacy > Permission Manager > Location and checking which apps appear there.
if you see Pingo listed under “Allowed all the time” on your child’s phone, it is there. it is not invisible. the phone knows.
on iOS 14 and later there is literally an orange dot that appears when the microphone is active and a green dot for camera. location access shows up in the status bar too. Apple made it pretty hard for apps to run fully silently.
so @StackExplorer: no, Pingo does not have a magic cloak. the device itself will show traces of it running if you know where to look.
I feel you on this one. When my daughter turned 11 and got her first phone I spent like three evenings reading forums exactly like this one 
the thing that helped me most was realizing my goal was safety, not surveillance. those are actually different goals and they lead to different tools.
for safety, you want to know if your child is somewhere unexpected, if they are talking to strangers, or if they are accessing content that is not appropriate for their age. you do not need to see every single thing they do. and more importantly, your kid does not need to feel like they are living under a microscope.
I ended up having a conversation with my daughter first. told her here is what I can see, here is why, and here is what I will not check unless I have a real reason to be worried. that conversation did more for our relationship than any app setting.
she still tests limits, obviously. she is 13 now. but she comes and talks to me when something weird happens online because she knows I am not just waiting to catch her doing something wrong 
whatever tool you pick, have that conversation first. seriously.
lol okay I love that this thread exists because I had THE most chaotic experience with a third party monitoring app last year and I will never go back. I installed something similar to Pingo on my son’s tablet. worked fine for about two weeks. then one day he comes to me and goes “dad why does this app have access to my photos” because Android sent him a permission summary notification
so now he knew it was there, he was upset I did not tell him, and I had to have a whole conversation I was not prepared for. ended up being fine actually but it could have gone so differently.
now I just use the router. that is my method. I logged into my home router settings and set up content filtering at the network level through our ISP’s family controls. nothing to install on his device at all. it filters what comes in and out of our whole network.
works on wifi obviously. does not work when he is on mobile data outside the house. so it is not a complete solution. but for home use it is clean and simple and there is no app on his phone for him to find 
DNS-Level Filtering With Parental Controls
Alright fellow tech nerds, let me give you the slightly more interesting answer here 
What Is DNS Filtering and Why It Works
Every time a device on your network visits a website or app, it first asks a DNS server to translate the domain name into an IP address. If you control the DNS server that your home network uses, you control which domains resolve and which ones get blocked. No app needed on the child’s device at all.
Setting It Up With Cloudflare for Families
Step 1: Log into your router admin panel. Usually accessed by typing 192.168.1.1 or 192.168.0.1 into a browser. Check the sticker on your router for the default login.
Step 2: Find the DNS settings. It is usually under WAN settings, Internet settings, or Advanced settings depending on your router brand.
Step 3: Change the Primary DNS to 1.1.1.3 and Secondary DNS to 1.0.0.3. These are Cloudflare for Families addresses that automatically block malware and adult content.
Step 4: Save and restart your router.
Step 5: On any device connected to your wifi, test it by trying to visit a known adult site. You should get a block page.
What This Does Not Do
This blocks content at the network level but does not give you location data or app usage reports. Also if your kid switches to mobile data instead of wifi, the filter does not apply.
For location tracking you would still need something device-based. But combined with a simple location sharing app, this setup covers most bases without any monitoring software showing up on their phone.
OpenDNS FamilyShield With Per-Device Rules
Going One Step Beyond Basic DNS Filtering
I saw kodevortex mention Cloudflare and that is a solid approach. Let me give you a version that lets you get a bit more specific about which devices on your network get filtered versus which ones do not 
Why This Matters
If you have a teenager and a 7 year old, you probably want different rules for each. OpenDNS lets you do per-device filtering once you set up a free account.
Setup Steps
Step 1: Go to opendns.com and create a free Home account.
Step 2: In your account dashboard, note your OpenDNS server addresses (208.67.222.123 and 208.67.220.123 for FamilyShield).
Step 3: Log into your router and update the DNS settings to those OpenDNS addresses.
Step 4: Back in your OpenDNS dashboard, go to Settings and add your home IP address. You can find your external IP by searching “what is my IP” in Google.
Step 5: Under Web Content Filtering, select the filtering level. Low, Moderate, or High. You can also block or allow specific categories like social media, gaming, or streaming.
Step 6: For per-device rules, use your router’s device management section to assign a static local IP to your child’s device. Then in OpenDNS, create a separate policy for that IP.
The Honest Limitation
If your child uses a VPN or switches to mobile data, this bypasses completely. For younger kids this is rarely an issue. For tech-savvy teenagers, you may need to pair it with something else. Still a great baseline layer though.
okay real talk for a second because I think this thread is getting a bit too technical and losing the actual parent who asked the question
StackExplorer the short answer to your original question: Pingo, like most monitoring apps, leaves traces on the device. it shows up in the app list, in battery usage, in permissions. a curious kid who goes looking will find it. it is not fully hidden.
if you are worried about privacy being compromised, that concern is actually a good instinct. the apps that claim to be completely invisible are usually the ones that are the most invasive in what they collect.
my recommendation: use the official tools made by the phone manufacturer. Samsung has its own parental controls called Samsung Kids for younger kids and Digital Wellbeing for older ones. these are built into the phone, they do not require a separate download, and they are pretty transparent about what they do.
the goal is to protect your kid, not to feel like a detective. and honestly when you parent from that mindset the whole thing feels less stressful
Setting Up Parental Controls Through Your Mobile Carrier
The Layer Most People Forget About
Everyone in this thread is talking about apps and router settings, which are both valid. But there is one more layer that sits underneath all of that: your mobile carrier 
If your child has their own SIM card or is on your family plan, the carrier itself can filter content and give you usage reports regardless of what apps are on the phone or which wifi network they are connected to.
How to Set It Up (Works for Most Major Carriers)
- Log into your carrier account online or through their official app.
-Navigate to the account management or family plan section. Look for labels like “Parental Controls,” “Smart Family,” or “Family Controls” depending on your carrier.
-elect your child’s line from the list of devices on your plan.
-Enable content filtering. Most carriers offer age-based presets. Choose the one that matches your child’s age range. - Set data usage alerts. You can get a notification when your child’s line hits a certain data limit, which is useful for monitoring heavy usage without seeing the actual content.
-Some carriers also offer location tracking per line. Enable this if you want to know where the phone is without any third party app at all.
Why This Works Even Outside Your Home Wifi
Because it operates at the network level from the carrier’s end, it applies to mobile data connections too. Combined with router filtering at home, this covers your child whether they are at home, at school, or anywhere in between.
The carrier method does not show the child a pop-up notification the way an app might. It is quiet and works in the background without requiring anything installed on their device. Most people do not even know this option exists 
you know what, I just want to say something that is not about the technical stuff for a second
being a parent right now is genuinely hard. the internet your kids are navigating looks nothing like what any of us grew up with. it is okay to want some visibility into what they are doing. that does not make you a controlling parent. it makes you a present one.
I went through a period of feeling really guilty for wanting to know what my son was doing online. like I was somehow not trusting him. then he showed me something disturbing a classmate had sent him in a group chat and I was so glad we had already established that I was someone he could come to.
the tools are secondary to the relationship. whatever you set up, make sure your kid knows you are on their side. that changes everything about how they respond when something goes wrong online.
you are already asking the right questions by thinking about their privacy. that tells me you are approaching this from the right place 
I tried Pingo for about a month, and to answer your question directly: it is NOT invisible.
My 14 year old found it within the first week She saw it in the battery usage section and came and asked me about it. Which actually turned into one of the better conversations we have had because I was honest about why I installed it.
The thing about these apps is they all leave some kind of footprint. Battery drain, storage usage, permission logs, something. Older kids especially know where to look because they grew up with these phones.
What changed things for us was switching to Xnspy. It is a lot more thorough in terms of what it can show you, call logs, messages, location, app usage, and the setup is smoother than most of the other ones I tried. But more than the features, what I found is that it gave me enough information that I was not constantly checking. I looked once a week instead of every day, and that actually reduced my anxiety more than going all-in on monitoring.
Still told my daughter it was on her phone eventually. That part matters. But if you want a more complete picture of what your kid is doing online and you do it responsibly, Xnspy is genuinely one of the better options out there 
@DignifyAlloy good to know it workied for you!!! I personally love the app
Having the Phone Agreement Conversation Before Picking Any App
The Setup No One Talks About
Okay I am a school counselor and I see the aftermath of both extremes: parents who monitor everything and parents who have no idea what is happening on their kid’s phone. The most important step happens before you download anything 
Create a Family Phone Agreement First
This sounds boring but it genuinely changes how the whole monitoring thing lands with your kid.
Pick a Good Time
Not when anyone is upset or rushed. Sit down together, maybe during a meal, and frame it as “we are setting some house rules about phones together.”
Let Them Talk First
Ask your child what they think fair phone rules would look like. You will be surprised. Most kids have a sense of what is reasonable and being asked makes them feel respected.
Share Your Concerns Honestly
Tell them specifically what you are worried about. Not vague stuff like “the internet is dangerous.” Specific things like: I want to know where you are, I want to make sure no one is bothering you, I want to make sure you are sleeping at a decent time.
Agree on What You Will Monitor
Write it down. Literally. Something like: I will check your location through Google Maps. I have set content filters on the router. I will not read your private messages unless I have a specific reason to be worried.
Set a Review Date
Agree to revisit the rules in 3 months. This shows your kid the arrangement is not permanent and gives them something to work toward.
Follow Through on Your End
If you said you will only check location and you find yourself reading every text, you have broken the agreement. Kids notice and it damages the trust that makes the whole thing work.
Why This Changes Everything
Every app and method mentioned in this thread works better when your child knows the general framework. They are less likely to try to work around it, and more likely to come to you when something genuinely worrying happens online.
The goal was never the app. The goal is a kid who knows you are in their corner
