About this extension

Stashy is a 100% offline, privacy-first browser extension designed for PC gamers who maintain libraries across multiple platforms. By securely matching your local catalog, Stashy displays elegant visual indicators directly on Steam and Epic Games store pages, warning you if you already own a game, if you own a more complete edition, or if you own the base game while viewing a DLC package.

🌟 Key Features

Elegant Dark-Matte HUD: Sophisticated Apple/Notion-inspired minimalist cards that blend seamlessly into native page layouts without glowing AI distractions.
Bilingual Support (EN / TR): Instantly toggle between English and Turkish languages directly from the extension pop-up menu.
Base Game & DLC Guard: Automatically compares titles and triggers clean alerts if you own a base game but are viewing an expanded bundle.
Zero-Click Passive Sync: Simply browse your Steam Games list or Epic Transactions page, and Stashy securely indexes your library in the background.
100% Private & Local: Zero external server connections, zero data collection, and zero credentials required. All data remains strictly inside your browser sandbox.
