CONTACT
Tell us about the task, not the confidential file.
Good feedback explains the workflow, the rule that feels unclear, and the outcome you would expect.
Current feedback channels
A public support address has not been published. The site has no feedback form or file-upload channel. If you already have a verified contact with the project owner, send a description of the issue rather than a workbook.
What useful feedback includes
Describe the task in plain language, your browser and whether you used the English or Chinese page. If an example is needed, invent small, synthetic values rather than sharing a real workbook or screenshot.
What to leave out
Do not include company records, supplier details, internal item numbers, quotes, drawings, passwords or API keys. The project does not need real business data to discuss a general workflow.
