Welcome to ProCalc (https://procalc.online). Your privacy is important to us. This Privacy Policy explains how we collect, use, and protect your information when you use our website and calculator tools.
The short version:We don't collect personal data. All calculations run entirely in your browser. We don't track individual users, sell data, or require sign-ups.
ProCalc does not collect, store, or process any personal information. We do not require you to create an account, provide your name, email address, phone number, or any other personally identifiable information to use our calculators.
All values you enter into our calculators (such as investment amounts, salary figures, subscriber counts, etc.) are processed entirely within your web browser using client-side JavaScript. No calculator inputs are ever sent to our servers. Your financial and personal data never leaves your device.
Like most websites, our web hosting infrastructure may automatically collect certain non-personally-identifiable technical information, including:
This information is collected in aggregate form and cannot be used to identify individual users.
The limited, non-personal information we may collect through standard web server logs and analytics is used solely to:
We never sell, rent, trade, or share any information with third parties for marketing purposes.
ProCalc may use strictly necessary cookies for basic website functionality, such as remembering your cookie consent preferences. These cookies do not track you across websites and do not contain personal information.
We use Google Analytics 4 (Measurement ID: G-1D555J426L) to understand aggregate website traffic and usage patterns. Google Analytics uses cookies to collect anonymized data about page views, session duration, and user interactions. IP addresses are anonymized, and we have configured Google Analytics to respect Do Not Track (DNT) browser signals where possible.
You can opt out of Google Analytics tracking by installing the Google Analytics Opt-out Browser Add-on.
ProCalc displays advertisements through Google AdSense (Publisher ID: ca-pub-2833735971305636) to support the free operation of our tools. Google AdSense uses cookies, including the DoubleClick DART cookie, to serve ads based on your prior visits to our website and other websites on the Internet.

We use Google Fonts (Inter font family) for typography. When you visit our website, Google may collect anonymized usage data through font requests. Google Fonts are served with preconnect hints to improve performance.
We use Vercel Speed Insights to monitor website performance metrics such as page load times and Core Web Vitals. This service collects anonymized performance data to help us optimize user experience.
Our website is hosted on Vercel's infrastructure. Vercel processes web requests and maintains standard server logs for security and performance monitoring. Vercel does not have access to your calculator inputs, as all calculations run client-side.
We carefully select third-party services and do not integrate any services that require access to your calculator inputs or personal data.
Since we don't collect personal data, there is minimal data to secure. However, we still take security seriously:
ProCalc is a general-purpose calculator website suitable for all ages. We do not knowingly collect any personal information from children or any other users. Since our tools require no registration and collect no personal data, children can safely use our calculators under parental guidance where appropriate.
If you are located in the European Economic Area (EEA), you have certain data protection rights under the General Data Protection Regulation (GDPR). Since we do not collect personal data, traditional GDPR rights (access, rectification, erasure, portability) are not applicable. However, you have the right to:
If you are a California resident, the California Consumer Privacy Act (CCPA) provides you with rights regarding your personal information. Since we do not sell personal information or collect personal data beyond standard web analytics, CCPA's "Do Not Sell My Personal Information" provisions are not applicable. However, you can:
Regardless of your location, you always have the right to:
Our website is hosted on servers that may be located in various countries. The third-party services we use (Google AdSense, Google Analytics, Vercel) may process data in the United States and other countries. These services comply with applicable data protection frameworks such as the EU-U.S. Data Privacy Framework.
Since we do not collect personal data through our calculators, international data transfer concerns are limited to standard web analytics and advertising cookies managed by third parties.
We may update this Privacy Policy from time to time to reflect changes in our practices, third-party services, or for legal, operational, or regulatory reasons. Any changes will be posted on this page with an updated “Last updated” date at the top. We encourage you to review this page periodically.
Material changes to this policy will be prominently announced on our homepage or through our cookie consent banner.
