Parents: what this tool is, and what it is not
You have probably arrived here looking for a way to protect a child. This is not that tool, and it is more useful to say so than to sell you something that will disappoint you.
Kellet is single-user and self-imposed. It has no parent account, no remote dashboard, and no covert mode, so it cannot be used to supervise a child. For that, use a purpose-built parental-control product. Kellet fits one case: an older teenager who wants the block themselves.
Why we do not build parental controls
The thing that makes a self-imposed blocker work is that there is no supervisor to appeal to. Add a parent account with an override and you have rebuilt the escape hatch the whole design exists to remove.
There is also a line we will not cross: no covert install, no hidden mode, nothing that conceals itself from the person using the computer. Those are the exact features a monitoring product needs, and they are the difference between a commitment device and spyware.
The case where Kellet does fit
An older teenager who has decided they want this for themselves is a genuinely different situation. A tool they set up and control, with a cool-down doing the work a parent holding a password would otherwise do, avoids the relationship cost of being policed.
That only holds if it is actually their choice. Installed against their wishes it is surveillance with extra steps, and it will be treated as such.
How to judge a parental-control product
Since this page is sending you elsewhere, here is what actually separates them. The feature lists are close to identical and the differences that matter are not on them.
- Does it cover the devices your child actually uses?The console, the tablet, the school laptop and the friend's phone. Coverage on one device moves the activity to another rather than stopping it.
- Does it filter content or only domains?A blocklist is a losing race against sites registered this morning. On-device image detection is the meaningful difference in this category.
- What does the child see?Products vary from an open, explained filter to something close to covert surveillance. That choice shapes the relationship more than the software does.
- What happens as they get older?A tool with no path from supervision to self-management becomes something to escape at sixteen rather than something to take over.
The part the software does not do
Filtering buys time and reduces accidental exposure, which is genuinely worth having, particularly for younger children. What it does not do is prepare a teenager for the internet they will have unsupervised access to in a few years.
The uncomfortable version is that a filter is most effective at exactly the age when the conversation matters least, and least effective at the age when it matters most. By the time a determined sixteen-year-old wants around it, they will get around it, and what remains is whatever you have talked about.
That is not an argument against using one. It is an argument against treating the install as the end of the task.
If you are here for yourself
A lot of parents arrive at this category for their own devices and find the whole space assumes they are shopping for a child.
If that is you, everything on the rest of this site applies. It is built for the device in your own hands, and it is worth saying that wanting this for yourself is not a lesser version of wanting it for a child.
