This extension collects the following data from the Tapbit Agent dashboard (agent.tapbit.com):

• Futures position data (coin name, direction, entry price, quantity, margin, leverage)
• Account balance data (equity, available balance, unrealized PnL)
• Masked user ID and remark name for display purposes

3. How We Store Data

All collected data is stored locally in your browser using Chrome's built-in storage API (chrome.storage.local). No data is transmitted to any external server, cloud service, or third party.

5. Data Sharing

This extension does not share, sell, or transmit your data to any third party. Data is only passed between browser tabs (from agent.tapbit.com to pro.coinstep.co.kr) within your own browser.

6. Data Retention

Data persists in chrome.storage.local until you:

• Uninstall the extension
