From the founder

I'm a new dad. I built the app I wished someone had handed me.

Becoming a father showed me how many things I wasn't prepared for. One of them never left the back of my mind: how do I protect my kids in an internet age I understand better than most, and still can't fully control?

The question that started it

“How do I protect my kids online, practically, without becoming a security expert?”

Being the tech guy in the family, that one was mine to answer. SafetyKit is the answer I could stand behind: the checks a security professional runs, explained in plain English, with the next step attached.

My story

Nobody prepares you for this part.

  1. Part 1

    I became a dad and found out how much I wasn't ready for.

    Nobody hands you a manual. The sleep, of course. But also the quieter part: every decision now has a small person on the other end of it. Most of that you learn by doing, and you are allowed to get it wrong.

  2. Part 2

    One worry never left the back of my mind.

    How do I protect them online? Not in theory. Which apps, which settings, which link, which stranger in which game. I'm the tech guy in my family; when something online feels off, I'm the one who gets the text. I did not want to be the one who dropped the ball on my own kids.

  3. Part 3

    So I used the training I already had.

    I hold a master's degree in cybersecurity. I spent years learning how people get compromised and how to find out whether they have been. Almost everything a parent needs to know is already public; security professionals check the same sources every day. Parents never get to, because every tool assumes you already speak the language. I decided this app needed to exist, and that a dad with the training should be the one to build it.

Sound familiar?

If you've ever thought one of these, this is for you.

These are the questions I kept asking myself. Each one is a check in the app, answered from public sources, with the sources shown so you can verify it yourself.

See which checks are free
  • “Is this link my kid just got actually safe?”

    Link check. Paste a link your child received and find out if it looks like a scam, a fake login page, or a site known for spreading viruses.

  • “Which apps is my child really on?”

    Username check. See which apps and sites your child's username shows up on, so you know where they have accounts you may not have heard about.

  • “Has their email or password leaked somewhere?”

    Email leak check. Find out if your child's email address has been leaked in a hack, which usually means the password on that account should be changed.

  • “Who is the number that keeps texting?”

    Phone number check. See where an unknown number that's been texting or calling your child actually comes from, and whether it's the kind of internet number scammers use.

  • “Can strangers see our baby monitor?”

    Home network check. See your home's internet connection the way a stranger sees it: are any cameras, baby monitors, smart devices or your router's login page reachable from outside?

  • “Is this app okay for a nine-year-old?”

    App check. Type the name of an app your child wants and get Apple's age rating, what kind of content it contains, and whether strangers can message them inside it.

What I want it to do for you

Four promises, written down.

Straight answers

Where this is right now.

A new launch, said plainly

SafetyKit launched in September 2026. There are no glossy customer quotes here because there are no customers yet, and I would rather tell you that than invent some. I am looking for the first 100 parents to use it, tell me where it falls short, and shape what gets built next.

Founding parents get a direct line to me and a say in the roadmap.

How it makes money

The free plan is real and stays free: 10 questions and 5 check credits a month for one child, 15 of the 18 checks, and every walkthrough to read. Plus and Family are paid so the business never has to sell data or show ads.

There is a 7-day free trial on both, and you cancel through Apple or Google, not through me.

Tell me what worries you most.

Get the app, or email me the ages of your kids and the thing you keep thinking about. I read every message, and the first 100 parents decide what gets built next.
