Defenras is a Canadian company making parental control and content-filtering software. The product blocks harmful content across every browser and app on a device — and is built so that we never hold a record of what your child looked at.
One filtering layer that works across iPhone, Android, Windows, macOS, and ChromeOS, plus browser extensions for Chrome, Edge, and Firefox. It blocks adult content, gambling, vaping and nicotine retail, scam and phishing sites, malware, and anonymous chat apps — with parent-controlled rules for social media and specific apps.
Filtering happens at the DNS layer on the device. That single design decision drives most of what makes the product different: it applies to every browser rather than one, it survives private browsing, it works on cellular rather than just your home Wi-Fi, and it requires no visibility into the contents of your child's traffic.
Most parental control products are monitoring products. They record browsing, searches, and sometimes message content, then show it to a parent in a dashboard. That's a legitimate product, and it isn't the one we build.
Defenras does not collect your child's browsing history. Filtering is a blocklist check performed at DNS resolution — the question asked is "is this domain blocked?", and the answer is not recorded. There is no browsing log on the device and none on our servers.
What we do hold is the minimum needed to run the service: your account email, subscription status, which devices are enrolled, and your blocklist configuration.
This has a real cost, and we'd rather state it than have you discover it. We cannot show you activity reports. No list of sites visited, no search history, no per-app usage breakdown — because we don't have the data to build them from. If that visibility is what you're looking for, a monitoring product will serve you better, and we'd rather say so than sell you the wrong thing.
Our reasoning is set out at length in what data parental control apps collect, including a method for auditing any product in this category — ours included.
Blocking is only as good as the lists behind it, so this is worth being specific about.
Categories rebrand constantly — anonymous chat apps in particular. That's why the product blocks by category rather than by a fixed list of names, and why a maintained feed matters more than any list a parent could keep by hand.
Most of the questions we get aren't about our software. They're "how do I turn off private browsing", "my child's Family Link supervision ends at 13, now what", "what do I do if this has already happened".
So we write those answers down, including the ones where the honest answer is that a free built-in tool does the job and you don't need us. Where a competitor genuinely does something better, we say which and why.
How that content is researched, sourced, and corrected is set out in our editorial standards.
We build software. We are not clinicians, lawyers, or law enforcement. Our guides cover serious subjects — sextortion, grooming, self-harm, disordered eating — and where they do, they point to the organisations that hold the actual expertise and link directly to them. A content filter is a useful layer. It is not treatment, legal advice, or a substitute for professional help.
