One inbox, read by a human. Corrections are especially welcome: every figure here comes from a named public source, so if something looks wrong, tell us which tool and figure, and link the source if you can.
We aim to reply within a few business days. Privacy and data-rights requests are answered within 30 days, as required by law.
Corrections
Say which tool, which place, store or member, and which figure is wrong. A link to the official source showing the right value is the fastest way to a fix.
Suggest a dataset
Know a public dataset that should be a tool? Send the link and the question you would want it to answer.
Privacy requests
Access, deletion, objection or withdrawal of consent: say which right you are exercising. See the Privacy Policy.
Businesses and officials
If a record about your business or office is wrong or out of date, tell us. We will check it against the original source, and correct or annotate it.
Rights and takedowns
If something here infringes your rights, identify the material and your interest in it and we will review it promptly.
