Exports

Choose the file that keeps the useful detail

For Tellune, the best starting point is a one-to-one WhatsApp text export without media. It gives the parser ordered message lines and, when WhatsApp includes readable timestamps, the timing data needed by reply-pace, session, long-wait, and late-night indicators.

Screenshots are a best-effort alternative when an export is not available. They require a separate extraction step and can lose timing or ordering detail, so the app may hide indicators that do not have enough reliable data.
