Other reasons to write in
Most messages we get fall into a few buckets, and all of them are welcome. Some people write in because a calculation looked wrong and they want us to check it — that's genuinely useful, because a quiet math bug can sit unnoticed for months if nobody says anything. Others write in with a tool idea: a unit conversion we're missing, a format the QR generator doesn't support yet, or a feature on an existing calculator that would make it more useful. We can't promise to build everything that's suggested, but we do read every request, and more than a few of the tools currently on Allcals started life as an email just like the ones we're describing here.
We also hear from people about the ads on the site. We rely on advertising to keep every tool free and account-free, but we know ads can sometimes misbehave — loading slowly, looking oddly placed on a particular screen size, or in rare cases showing something that doesn't belong on a tools website. If you ever see something like that, please tell us exactly which page it was on and, if you can, what the ad looked like. We follow up on these reports with our ad network directly.
Press, partnership, or business inquiries are also fine to send through this form — just make that clear in your subject line so it gets routed appropriately on our end. We're a small operation, so we can't guarantee every business proposal gets a response, but relevant ones do get read.
A note on privacy
When you use the form above, your name, email address, and message are sent to our inbox through a third-party form-delivery service so that we don't need to run our own server-side code just to receive a message. We don't add you to a mailing list, sell your information, or use your email for anything beyond replying to what you wrote. For more detail on how data moves around this site generally, see our Policy page.
Not a substitute for professional advice
One last honest note: while we're happy to answer questions about how a tool works or why a result looked a certain way, nothing we send back through this form should be treated as medical, legal, or financial advice. For anything in that territory, please talk to a licensed professional — our Disclaimer page goes into more detail on this.
Frequently asked questions
How long does it take to get a reply?
Most messages get a reply within one to three business days. If you haven't heard back after a week, it's worth checking your spam folder first, then sending a short follow-up — occasionally messages do slip through.
Can I request a brand-new tool?
Yes, and we genuinely like getting these. Tell us what the tool should do and, if you can, an example of the kind of input and output you'd expect. That context makes it much easier for us to build something that actually solves your problem.
I found a mistake in a calculation — what should I do?
Send us the exact numbers you entered, the tool you were using, and the result you got. We'll test it on our end and fix it as quickly as we can if something's genuinely off.
Do you offer technical support for other websites or software?
No — Allcals is limited to the tools on this site. We're not able to provide general tech support beyond that.
Thanks for taking the time to reach out. Feedback — good, bad, or somewhere in between — is genuinely how this site gets better.
