Contact us
We read every message. Whether you've found a bug, want to suggest a tool, spotted an inaccuracy, or have a question about how something works, we'd like to hear from you.
The fastest way to reach us is by email: hello@toolhose.org. We aim to respond within a few business days.
What to include
- Reporting a bug or wrong result? Tell us which tool, what you entered, what you expected, and what you got. If you can, mention your browser and device.
- Suggesting a tool? Describe what it should do and who it's for. We prioritize tools that are genuinely useful and that we can build to run privately in the browser.
- Reporting an inaccuracy? Point us to the page and, where possible, an authoritative source. We take accuracy seriously, especially for anything involving numbers.
