About & contact

Whether you found a bug, a typo or a better way to do something, we are glad to hear about it. Email [email protected], or use the form below to start a message. Email works best for us, as it lets us test what you describe before we reply.

How we can help

Messages about any of the following are especially helpful, and a page address makes them quicker to act on:

• Corrections. If a result, a formula or a sentence in a guide looks wrong, tell us which page it is on and what you expected to see.
• Suggestions. If there is something the tool should do but doesn't, describe it and how you would use it.
• Bug reports. If something doesn't work, mention your browser and device and the values you entered, so that we can reproduce the problem.
• Copyright. If you believe material here infringes your rights, see our DMCA page for what to include.
• Privacy requests. Questions about data and requests to exercise your rights are welcome; see our Privacy Policy for details.

Write to us

The form only prepares an email. Your mail app opens with everything filled in, and the message goes out from your own account when you press send. No mail app on this device? Just email [email protected].

Before you write

• We use your address only to answer you; we do not send newsletters.
• There is no need to send sensitive personal data; a description of the issue is enough.
• If we use an idea you suggest, we may do so freely and without obligation.
• We cannot give personal engineering, medical, legal or financial advice about your specific situation.
• All messages are read; where a response is needed, we send one.

Before you email

The guides on name-compatibility.com explain the method behind the name compatibility calculator and may already answer your question. Our Privacy Policy, Terms of Use and DMCA page cover data, the rules of use and copyright respectively. If you still have a question after that, the form above is the easiest way to ask it.
