Purus significantly reduces exposure to explicit content but cannot guarantee complete filtering of all online content.
Sound familiar?
The problems Purus is built for.
Much of the internet is designed to hold your attention, and many filters can be turned off in a moment of weakness. Purus is built the other way around.
One wrong tap
Filters that are easy to get around
Mentor, not monitor
Focus that slips away
Weak moments
Protection without a report card

One of the Most Comprehensive Content Filters Available*
Purus stacks eight independent layers of protection — from DNS to keyword to platform-specific filtering — so very little slips through.

FAQ
Questions, answered honestly.
No. Purus has no accounts and sends no reports or screenshots to anyone. Filtering decisions happen on your device, and your history, bookmarks, and tabs stay on your phone. A few things leave your device only in limited ways: Purus fetches updated block lists, DNS protection (if you turn it on) sends domain lookups through AdGuard's family filter, tapping ‘Report it’ submits that one URL to us, and Search Suggestions (if you enable them) send partial search text to your chosen search engine. The Privacy Policy covers each in full.
The app appears on your home screen as “Purus”. Subscriptions are processed by Apple, like any App Store purchase.
About Purus
Built to do one thing well.
My name is Nick Soter and I’m the founder and chief engineer of Purus. More importantly, I’m a husband, an oldest brother, a son, a friend, and someone who deeply cares about the community around me. As I’ve studied Information Systems, Psychology, and Business I became fascinated by human behavior and how technology can either compromise or protect our mental well-being.
Growing up, serving in my church, and interacting with people in all walks of life I quickly saw that pornography was a universal problem among men and women of all ages. While studying the issue, I saw that existing solutions are great but often too expensive, complicated, or intrusive. While working with people I realized that their frustrations were the same as mine: there really isn’t a seamless way to block explicit and distracting content automatically without a catch.
We are at a point in technology where things are rapidly changing. With recent breakthroughs in AI, we can actually catch explicit content automatically. I realized that by implementing current technology and using it to fix a problem that affects so many people, we could help change lives in a very meaningful way. This is where Purus was born; a simple solution to a complicated problem.
This app came after a year of brainstorming with very bright minds, conversations with real people, and months of development to create what you’re downloading on your phone today.
It took hundreds of tweaks, dozens of iterations, and a firm belief that we could create something that would bring lasting impact. Finally it’s here, and as the chief engineer and founder of the company, I’m thrilled you’re here and are willing to give us a try. I hope that this app becomes to you what it means to me; a symbol of virtue, cleanliness, security and certainly a safer, cleaner, online experience.
The web, without the parts you don't want.
