Is QuantCrawler Chart Analyzer safe?

Clean risk

QuantCrawler Chart Analyzer uploads user-triggered TradingView chart screenshots to QuantCrawler for analysis.

When the popup or keyboard command runs on an active TradingView tab, the extension captures chart screenshots as PNG data URLs and stores them locally. It then sends the ticker, market, mode, selected timeframes, and captured images to QuantCrawler for analysis.
