The client and the problem
Hidden Reflex builds and publishes Epic Privacy Browser, its own Chromium-based privacy browser. Hidden Reflex brought us in for defined pieces of Chromium development on Epic.
What we built
Hidden Reflex hired us through Upwork for Chromium development work on Epic Privacy Browser, then hired us again for a second engagement. In both, we delivered code changes and fixes to the scope Hidden Reflex set. We did not create Epic: its brand, privacy features and product design belong to Hidden Reflex.
- Chromium development work on Epic Privacy Browser, to a scope set by Hidden Reflex
- Fixes within that scope, delivered as agreed
Why it was hard
Working inside another company’s browser means fitting its code base, its build and its release process. Changes have to follow the existing conventions and stay easy for the product’s own team to carry forward to the next Chromium version after we hand them over.
In the client’s words
“Project delivered successfully. The developer was willing to go the extra mile for fixes within scope.”
About the product
The product as its owner describes it. These are the client’s features, not a list of our work; our part is under “What we built”.
Epic Privacy Browser is a free, Chromium-based browser made by Hidden Reflex. Its website says Epic always runs in private browsing mode and clears cookies, cache and history when it closes.
Epic blocks ads, trackers and cryptomining scripts, and blocks many fingerprinting methods, including canvas, font and audio-context fingerprinting. It is offered for Windows, macOS, Android and iOS.
