Contact
One address, read by a person. There is no contact form here because a form would mean sending your message through a third-party service, which sits awkwardly with the rest of the site.

Something is broken
A tool giving the wrong result, a page that will not load, a style that renders as empty boxes. Tell us which browser and which page, and paste the input if it is not sensitive.
Write about thisA tool that should exist
If you keep searching for something and landing on a bad version of it, that is exactly the kind of suggestion worth sending.
Write about thisPrivacy and your data
Questions about what is collected, or a request to access or delete your analytics record. We answer within 30 days.
Write about thisOne thing to keep in mind
Do not send us tokens, passwords, API keys or personal data belonging to other people, even to reproduce a bug. Email is not a secure channel, and the whole design of this site is that we never see that kind of thing. Describe the shape of the input instead — how long it was, which format, which characters — and that is almost always enough to find the problem.
