Capabilities

Zero Data Transfer: No uploads, no servers, completely private.
Client-side Parsing: Reads WhatsApp exports locally. Nothing is kept between visits unless you turn on Persistent Storage (Beta) in Settings, which saves a copy on this device only.
Memory-aware Media: Keeps ZIP attachments local and loads media only when it is needed.
Sliding Message Window: Adds nearby messages as you scroll and drops older rendered content from the opposite side.
ChatLume Wrapped: Extract emojis and hourly patterns to generate a personalized, shareable graphic.
Analytics: View total counts, media usage, and per-sender conversation shares.

Notes

ZIP exports provide the richest experience, and attachments are decoded lazily as they enter view.
Off-screen media object URLs are released automatically to keep memory usage low during long sessions.
Browser limits still apply. Very large media files can take a moment to decode, but the app avoids loading the entire export into the DOM.
