Privacy policy

MetalCalc Pro is designed to run calculations in your browser. We do not sell personal data and we do not use third-party advertising trackers on the calculator pages.

Depending on how you use the site, we may process the following categories of data:

• Inputs and results you enter in the calculator, stored locally in your browser until you clear site data.
• If you create an account, authentication is handled by our identity provider (e.g. Apple or Google) and optional cloud sync may store calculation snapshots you choose to upload—governed by their and our infrastructure provider’s terms.
• Technical logs (IP address, user agent, timestamps) that hosting providers generate automatically for security and reliability.
• Email correspondence when you write to us via the address on the contact page.

You may request deletion of account-related data where applicable by emailing us from the address associated with your account.

This policy may be updated; the “last updated” moment is the publication date of the page version you are reading. Continued use after changes constitutes acceptance of the revised policy.
