Have a question about one of our calculators, spot a spec that looks wrong, or just want to send feedback on the site? Use the form below to get in touch. We especially appreciate corrections — if a calculator’s assumption, a hardware page’s spec, or a guide’s explanation doesn’t match what you know to be true, telling us helps us fix it for everyone who reads that page after you.
This is also the right place to reach out about anything covered in our Privacy Policy or Disclaimer, including requests related to information you’ve previously submitted through this form. We read every message that comes in, though as a small, independently run site we can’t guarantee a specific turnaround time on every reply.
Frequently Asked Questions
How quickly will I get a response?
We read every message that comes in, but we can’t guarantee a specific response time. Straightforward corrections or questions are often handled faster than more involved requests.
I found an incorrect spec or a calculator result that seems off — what should I include?
It helps to mention the exact page (and calculator, if applicable), the inputs you used, and what you expected versus what you saw, or the correct spec if you’re reporting a factual error.
Can I request that my previously submitted information be deleted?
Yes — mention that in your message and we’ll act on reasonable requests. See the Privacy Policy for more detail on what information we retain.
