Privacy Policy

Last updated: March 2026

Information Collection and Use

At ProCalc, we take your privacy very seriously. We do not collect, store, or transmit any of the data you input into our calculators. All calculations are performed instantly using client-side JavaScript, meaning the data never leaves your device or is sent to our servers.

Local Storage

We may use standard browser technologies such as local storage exclusively to save your theme preferences (Light or Dark mode). This ensures a consistent user experience upon returning to the site.

Third-Party Services

We use standard web analytics to monitor traffic and improve our features. These services may collect standardized, anonymous information regarding device types, broad geographic demographics, and site usage statistics. They do not have access to any calculation data.

Changes to This Policy

We reserve the right to modify this Privacy Policy at any time. Any changes will be updated on this page with a revised "Last updated" date.
