What to include

Bug reports — the tool name, what you expected, what happened, and your browser and device.
Tool requests — a short description of the task you want to solve and an example input and output.
Content or policy questions — the page address and a description of your concern.

Please note

Please do not send passwords, private keys, personal data or confidential files by email. Our tools run in your browser, so we never need your data to diagnose a problem; a small, non-sensitive sample is enough.
