Privacy Policy - Gaijin Purchase Summary
Last updated: October 15, 2026
Note: This is an unofficial browser extension and is not affiliated with Gaijin Entertainment or PixStorm.
Gaijin Purchase Summary is committed to protecting your privacy. This extension is designed with privacy as a core principle.
🌐 Supported Websites
This extension only works on the following official store pages:
- https://store.gaijin.net/user.php?view=purchases
- https://store.pixstorm.ru/user.php?view=purchases
- https://store.gaijin.net/balance_history.php
- https://trade.gaijin.net/
📊 Data Collection
The extension handles data only to show your own spending statistics. It does not sell data, use it for advertising, or send it to the developer.
It does handle:
- Financial information shown on the store purchase page and the GJN balance ledger you have open: item names, prices, dates, top-ups, purchases and sales
- Authentication information: the market session token that trade.gaijin.net already stored in this browser, used only to read your trade history and lot names
It does not:
- Track browsing history outside the supported pages listed above
- Read your store password or payment card
- Place market orders or change your balance
- Use analytics or tracking cookies
- Send data to any server other than Gaijin's own market server, market-proxy.gaijin.net
⚙️ Data Processing
Processing happens in your browser:
- Reads the purchase history page you opened and totals prices, quantities, categories and gifts
- Reads the GJN ledger on the balance history page you opened
- Reads the market session from trade.gaijin.net and requests your trade history and item types from market-proxy.gaijin.net. If that page is not open, the extension may open it in the background so lot names and categories can load
- Stores your language, whether the panel is visible, the panel position, the market session token and lot names locally in the browser
💾 Data Storage
All data is stored locally in your browser using Chrome's storage API:
- Language settings preference (Russian/English)
- Popup visibility state (show/hide)
- Store purchase statistics are calculated on the page and are not saved
- The market session token and lot names are kept locally so the balance page can label deals
🔐 Permissions Explanation
- activeTab - To check if the current active tab is a supported store page and manage overlay state
- storage - To save your language, display preferences, and the market session token already issued to your browser
- trade.gaijin.net - To read the market session and, if needed, open the market page in the background
- market-proxy.gaijin.net - To read your trade history, lot names and item types
🌍 Multi-language Support
The extension supports Russian and English languages. Your language preference is stored locally and never transmitted externally.
🚫 Third-Party Services
Store purchase totals are calculated locally. Lot names for the GJN ledger are requested from Gaijin's own market server, market-proxy.gaijin.net, using the session the market site already created. The extension does not send that data to anyone else.
📈 Statistical Calculations
The extension performs the following calculations locally:
- Total purchase amount sum
- Count of total, paid, and free items
- Category breakdown: Golden Eagles, Premium Account days, Packs & Vehicles
- Quantity calculations for bundled items and gifts
- Dynamic currency formatting based on store page data
