Booth Companion – Booth.pm Currency Converter, Price Tracker & Shopping Tools Booth Companion is a privacy-focused Chrome extension for Booth.pm that converts Japanese Yen (JPY/¥) prices into your preferred currency and adds practical shopping tools for international buyers, VRChat users, VTubers, avatar creators, and digital-asset collectors. See converted product and cart prices, search your Booth library and wish list, track price changes, import cart or wish-list items into the price tracker, compare products side by side, calculate bundle savings, highlight avatar compatibility, and mark items you already purchased or received as gifts. Booth Companion can also export your library, show detected product dependencies, calculate total spending and favorites value, highlight free items, and customize Booth with themes. Currency conversion uses exchange rates updated twice daily, with an optional manual rate override and flexible number formatting. Estimated converted-price history charts help you understand how exchange-rate movement affected prices over 7, 30, or 90 days. Your Booth account data is not collected, sold, or used for advertising. All Booth Companion settings are stored locally in your browser. ✨ Key Features 💱 Booth.pm Currency Converter

🔒 Privacy-Focused by Design Booth Companion does not collect personal account data, run behavioral analytics, build advertising profiles, or sell user information. All extension settings—including custom themes, shop preferences, avatar aliases, price-tracker data, and purchase or gift scan results—are stored locally in your browser. Library, order, gift, cart, and wish-list pages are processed within the extension while you are signed in to Booth. Online features make temporary requests for exchange-rate data or public Booth item metadata from booth-companion.com. These requests may include a public Booth item ID, but they do not include your extension settings, Booth login credentials, cookies, order history, or personal account details. A local-only fetching option is also available for product-price tracking. ⚡ Performance Booth Companion reduces unnecessary Booth.pm analytics and third-party requests to help pages load more efficiently. 📢 Stay Updated Twitter/X: @CompanionGround Bluesky: @CompanionGrounds.com ⚠ Disclaimer Booth Companion is an independent browser extension and is not affiliated with, endorsed by, or operated by Booth.pm or pixiv Inc. Converted prices may differ from checkout totals because of exchange-rate timing, card-provider rates, taxes, and payment-provider fees. Dependency detection and avatar matching are automated shopping aids; always verify product descriptions and requirements before purchasing.
