Privacy BroDraw sends NOTHING to the internet. No telemetry, no crash reports, no analytics. All features - including OCR and AI - run fully locally in your browser. The only network connection happens when downloading the OCR language data (Tesseract tessdata from projectnaptha.com) on first OCR usage. The add-on itself contacts no servers of its own.
