Found a bug, have an idea for a tool, spotted a fact that is wrong, or want to talk business? Write to us — every message is read by a human.
We aim to reply within a few working days. There is no contact form on purpose — email works, and it doesn't need your data to be stored anywhere first.
Most of what gets built here started as somebody's suggestion. Tell us what you would actually use.
If a fact is wrong or a translation reads badly, tell us and it gets fixed.
What you did, what happened, and which browser you were using is enough to get it fixed.
Advertising, partnerships and press enquiries reach the same address.
