Contact
Questions, bug reports, ideas for a new tool: write to us. We read every message and reply when we can.
What to include
- Which tool, what you did, what you expected and what happened instead.
- Your browser and device, for anything that looks or behaves wrong.
- For a calculation, the inputs you used. A share link works too, but it contains your whole design, so only send it if you are comfortable doing so.
Why there is no contact form
A form would send what you type to a server, and no page on this site does that. Email goes through your own mail app, so you keep a copy and decide exactly what to share.
What happens to your message
We use your address and message only to reply and to deal with what you asked about. The Privacy Policy has the details.
