Contact

Use this page when you need to report an issue, request a correction, ask a privacy question, or contact the team about the platform.

ExpertToolkit is still expanding its full trust and support layer, so this page is designed to give users a clear route for the most important requests first: correctness issues, privacy or policy questions, and legitimate platform inquiries.

ExpertToolkit is founder-led by Anoop Kumar, a B.Tech Computer Science and Engineering graduate from VIT-AP University, based in Noida, India. Contact messages currently go through the founder-operated public inbox so issues about accuracy, trust, privacy, and platform quality can be reviewed directly.

Why to contact us

  • to report a calculator or converter issue;
  • to raise a privacy or policy question;
  • to request a correction;
  • to discuss business or platform-related inquiries.

1. Corrections and accuracy reports

If you believe a calculator, converter, table, formula page, or interpretation is wrong, unclear, misleading, or incomplete, contact us with the page URL, the issue you observed, and, if possible, the expected correction or authoritative source.

Accuracy and corrections reports should be treated as high-priority requests because they affect user trust directly.

2. Privacy and policy questions

If your question relates to privacy, cookies, data handling, or other trust-policy matters, use this contact path and clearly label the request as a privacy or policy inquiry. That helps separate legal or compliance-oriented questions from product feedback.

3. Technical issues and broken pages

If a tool does not load, produces an obvious rendering error, or appears to have a broken interactive surface, include the URL, device type, browser, and a short description of what happened. Screenshots or exact reproduction steps are helpful.

4. Business and platform inquiries

We also use this page as the intake path for legitimate business, partnership, product, and platform inquiries. Requests should be specific and clearly explain the context so they can be routed appropriately.

5. Founder-led accountability

ExpertToolkit is not operated as an anonymous calculator directory. The platform has a named founder, a public location, and a direct contact route for users who need to report problems, ask policy questions, or request corrections. That accountability is part of how the product is being built.

6. Current contact route

The current public contact email for ExpertToolkit is support@experttoolkit.net. For now, this single email can be used for corrections, privacy or policy questions, technical issue reports, and business inquiries.

7. Response expectations

Requests involving calculator correctness, privacy, or broken public pages should be prioritized over general feature suggestions.

Clear reports with page URLs, affected values, screenshots, and expected behavior are easier to review and resolve than general messages.
