Life is better when our devices are working for us and not against us. Our greatest tools ended up turning us into the product instead. They can show us a lot of interesting content, but do so with annoying ads. They can be very entertaining and useful, while at the same time tracking our every move.

As a computer scientist with multiple internet-connected devices in my home, I realized what I was exposing myself to. Whether it’s watching TV, listening to music, scrolling on my phone, or working on my laptop, my devices are constantly tracking me.

When I went looking for something affordable and easy to set up, I quickly realized it didn’t exist. Existing solutions were too complicated, cost too much, or required you to route your data through them. I needed a device my friends and family could just plug in to protect every device in their home.

Faced with this problem, I decided to build my own solution. Now anyone can block ads, stop trackers, and defend against dangerous intruders. Because it’s a physical device, the protection happens locally — your data stays in your hands.

I use PuriFi™ to block ads when I’m reading the news, browse the internet without being tracked, watch TV without being watched, and listen to music without being listened to. I hope you’ll like PuriFi™ as much as I do.
