Privacy Policy

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.

1. Information We Collect

1.1 No Personal Data Collection

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.

1.2 Calculator Inputs

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.

1.3 Automatically Collected Information

Like most websites, our web hosting infrastructure may automatically collect certain non-personally-identifiable technical information, including:

• Browser type and version
• Operating system
• Referring website URL
• Pages visited and time spent on pages
• General geographic location (country/region level, not precise location)
• Device type (desktop, mobile, tablet)

This information is collected in aggregate form and cannot be used to identify individual users.

2. How We Use Information

The limited, non-personal information we may collect through standard web server logs and analytics is used solely to:

• Monitor website performance and uptime
• Understand aggregate usage patterns to improve our calculators
• Identify and fix technical issues
• Determine which calculators are most popular to prioritize development

We never sell, rent, trade, or share any information with third parties for marketing purposes.

3. Cookies & Tracking Technologies

3.1 Essential Cookies

ProCalc may use strictly necessary cookies for basic website functionality. These cookies do not track you across websites and do not contain personal information.

3.2 Analytics

We may use privacy-focused analytics tools to understand aggregate website traffic. If analytics are implemented, they will be configured to anonymize IP addresses and respect Do Not Track (DNT) browser signals.

3.3 Advertising

ProCalc may display advertisements to support the free operation of our tools. Third-party advertising partners may use cookies to serve relevant ads. You can manage cookie preferences through your browser settings. We recommend using browser extensions like uBlock Origin if you prefer an ad-free experience.

4. Third-Party Services

Our website may use the following third-party services:

• Google Fonts — for typography (Inter font family). Google may collect anonymized usage data through font requests.
• Advertising networks — if ads are displayed, ad providers may use cookies for ad personalization. See their respective privacy policies for details.
• Hosting provider — our hosting infrastructure processes web requests, which includes standard server logs.

We carefully select third-party services and do not integrate any services that require access to your calculator inputs or personal data.

5. Data Security

Since we don't collect personal data, there is minimal data to secure. However, we still take security seriously:

• Our website is served over HTTPS encryption
• All calculations are performed client-side — no data is transmitted to servers
• We do not maintain user databases or authentication systems
• We regularly update our dependencies and infrastructure for security patches
• The X-Powered-By header is removed for security

6. Children's Privacy

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.

7. Your Rights

Since we do not collect personal data, traditional data rights (access, deletion, portability) are not applicable. However, you always have the right to:

• Use our calculators without providing any personal information
• Block cookies through your browser settings
• Enable Do Not Track in your browser
• Contact us with any privacy concerns

8. Changes to This Policy

We may update this Privacy Policy from time to time to reflect changes in our practices or for legal, operational, or regulatory reasons. Any changes will be posted on this page with an updated “Last updated” date. We encourage you to review this page periodically.
