Screenshots sees everything on your screen, can record your microphone and system audio, and keeps a history of captures on disk. A bug in any of these can expose someone's data, so please report it privately.
How: open a private security advisory on this repository. Please don't open a public issue for it.
What helps: the macOS version, the steps, and what was captured, kept or exposed.
You will get an answer within a week. Once a fix ships, the advisory is published with credit to you, unless you'd rather stay anonymous.
Supported: the latest release only.
