Found a bug, a wrong fact, or a list your export has that the viewer does not show? Open an issue on GitHub in the feedback repository we use for our tools — every one is read. Please include the tool page, your browser, and what you expected; for a file problem, the names of the sections in your export (not the file itself).
Issues are public: anyone can read what you write there, together with your GitHub username. Do not post personal data, and never attach an export file — it contains your data and other people’s. How the site handles data is explained on the privacy page.
