By default, Trojan Killer does not collect personal documents, browsing content, or anything you scan.
You can opt in (Settings) to send anonymous statistics that help improve detections, these include non-identifying technical signals like detection names and app version, not your files.
If you choose to send a manual report (Save to file…), it contains technical details we need to investigate: file paths, hashes, detection IDs, engine/version, and basic system info (OS build, language).
Reports are used only for troubleshooting and research quality.
