We welcome feedback, corrections, and suggestions for new calculators.

Email: contact@techshieldnews.com

If you've spotted a result that looks wrong, please include the calculator name and the exact numbers you entered so we can reproduce and fix it quickly. Accuracy matters to us, and we review every report.

For suggestions, tell us which calculator or tool you'd find useful — reader requests directly shape what we build next.

We aim to reply within a few business days.
