Contact us
We read every message. Bug reports, feature suggestions, content corrections, and partnership enquiries are all welcome.
The fastest way to reach us is by email:
We typically respond within two to three business days. If you don’t hear back within a week, please feel free to send a follow-up — messages occasionally end up in spam.
What to include
To help us respond quickly, please include the relevant items:
- Bug reports — the tool name and URL, what you did, what you expected to happen, what actually happened, and your browser/OS if known. A screenshot is gold.
- Calculation corrections — the tool, the input you used, the output we produced, and the output you believe is correct (with a source or formula if possible). We take accuracy seriously and will fix verified errors quickly.
- Feature requests — a sentence or two about what you’d like to do and why. Concrete use cases help us prioritise.
- New tool suggestions — describe the tool you’d like to see. We add new tools regularly based on reader requests.
- Privacy or data questions — see the Privacy Policy first, then email us if anything is unclear.
What we can’t help with
- Personal financial, medical, or legal advice. Our calculators (BMI, loan, compound interest, etc.) are general-purpose tools, not advice. For decisions that affect your health or money, please consult a qualified professional.
- Help with content you’ve entered into a tool. Because nothing you type into ToolBox is sent to us, we have no way to see your inputs or outputs. Please reproduce the issue with example inputs we can run ourselves.
- SEO / link insertion / sponsored content requests. We don’t accept guest posts, sponsored links, or paid backlinks. Please don’t ask.
Legal & press
For legal notices, copyright questions, or press enquiries, please use the same email address and include “Legal” or “Press” in the subject line so we can route the message appropriately.
