When you scan a meeting invite or poster:

Scanned Images: Photos you capture are sent to our OCR backend for AI-powered text extraction
Context Information: Your timezone, locale, and current date (to accurately parse dates and times)

Important: Images are processed in real-time and deleted immediately after processing. We do not store your scanned images on our servers.
