Contact

Have a question, found a mistake, or want to suggest a calculator? We would like to hear from you. Every message is read, and your feedback directly shapes which tools we build and fix next.

Get in touch

For questions, corrections, bug reports, accessibility issues, or ideas for calculators we do not have yet, email support@calcuto.com. When reporting a problem, telling us which calculator, what you entered, and what you expected helps us resolve it quickly.

We read every message and usually reply within a few business days. We cannot promise a guaranteed response time, but nothing gets ignored.

Partnerships & collaboration

Calcuto is open to partnerships and collaboration — integrations, data or API arrangements, content syndication, and licensing. If any of these fit what you are working on, get in touch at support@calcuto.com and tell us what you have in mind.

We are happy to keep early conversations informal, with no obligation on either side.
