Overview

Epic is a proprietary privacy-focused web browser developed by the Indian software company Hidden Reflex. The product is designed around the principle that ordinary browsing should leave as little identifying and behavioral data as possible on the user's device or with third-party services. It uses Chromium as its browser engine and is configured to operate in a private-browsing mode by default. When the browser is closed, it removes local browsing information such as cookies, history, and cached data. Epic also disables or removes a number of browser functions that can transmit information to external providers, including services associated with address-bar suggestions and installation tracking. The browser's privacy controls include default blocking of advertising and activity trackers, a persistent Do Not Track signal, preference for encrypted HTTPS connections, and defenses against several forms of browser fingerprinting. Epic restricts access to data that can be used to create a distinctive device fingerprint, including canvas, font-canvas, and audio-context information. It also blocks WebRTC behavior that can expose a user's IP address and prevents cryptocurrency-mining scripts from running on the user's computer. A proxy function was available as an optional privacy feature and was automatically used for searches in some configurations, although the proxy service was later deprecated in a newer version. Epic was initially based on the Firefox platform but moved to Chromium on August 29, 2013. The transition allowed the product to use the Chromium rendering engine while retaining its privacy-oriented configuration. The browser has also incorporated features aimed at users in India and has offered integrated widgets or facilities connected with social networking, chat, and email. Its design represents a trade-off between privacy and compatibility: reducing connections to large online service providers can limit features such as automatic search suggestions, translation, extension availability, and compatibility with certain websites. Epic is not open-source software, although Hidden Reflex has stated that it intended to make relevant files available for auditing. Independent coverage has described its blocking of advertising, trackers, referrer information, and fingerprinting mechanisms, while also noting that some websites and browser extensions do not function normally. The browser has advised users to avoid signing in to services such as Gmail while searching if they want to prevent those services from associating searches with their identity. Hidden Reflex has explored possible ways to support the product commercially, including premium privacy services and sponsored content, but the available reference material does not establish the browser's current commercial model, ownership structure, market share, or development status.

History

Epic was created by Hidden Reflex as a proprietary web browser centered on privacy rather than integration with the dominant advertising and search ecosystems. Its configuration is intended to reduce both persistent local records and the number of requests made to external services. The browser runs in a private mode by default, deletes session-related information when closed, and blocks many advertising and activity-tracking technologies without requiring users to install separate extensions. In its earlier development, Epic used Mozilla's Firefox technology. On August 29, 2013, Hidden Reflex changed the browser engine to Chromium. The shift gave Epic a different technical foundation while preserving its privacy-focused product philosophy. The Chromium-based version also included features intended to serve Indian users and integrated facilities such as social-networking, chat, and email widgets. Epic's privacy model extends beyond conventional private browsing. The browser removes or disables supplementary Chromium services that communicate with external servers, including features related to address-bar suggestions and installation tracking. It prefers HTTPS connections, sends a Do Not Track header, and blocks trackers and cryptocurrency-mining scripts. Its fingerprinting defenses limit access to browser and device characteristics that can be combined to identify a user, including canvas, font, and audio-context data. WebRTC IP-address leakage is also blocked by default. A built-in proxy service could be enabled by users and was automatically used for certain searches, but that service was deprecated in a later version. The product's privacy choices create practical compatibility costs. Features dependent on Google infrastructure, including some suggestion and translation functions, may be unavailable or handled locally. Epic has supported fewer Chrome extensions than a standard Chromium browser because extensions can introduce privacy risks. Some websites have also failed to work correctly, with an IE Tab add-on mentioned as a workaround for particular cases. The browser's own guidance has warned that signing in to services such as Gmail can allow Google to connect a user's searches with the account. Public commentary in 2020 examined both Epic's technical claims and its sustainability as a business. Hidden Reflex indicated that it was considering models involving premium privacy services and sponsorships, while also stating that it intended to release files for audit despite Epic not being open source. The available references do not provide reliable information about Epic's current version, active user base, headquarters, revenue, or present operating status.

Products and positioning

A privacy-first alternative to mainstream Chromium-based browsers, emphasizing tracker blocking, minimal data retention, and reduced reliance on external web services.

Web browser
Epic Privacy Browser
Epic's primary browser product is built on Chromium and configured to prioritize privacy by default. It removes local browsing data on exit, blocks advertising and activity trackers, prefers encrypted connections, sends a Do Not Track signal, and restricts several fingerprinting and IP-leakage techniques. It also removes or disables selected browser services that communicate with external servers. These protections can reduce compatibility with some websites, Google-dependent functions, and Chrome extensions.
