Privacy Policy

Last updated: March 25, 2026

We built CalculatorPro.net to be a helpful, no-nonsense tool — and that includes being upfront about your privacy. No fine print. No surprises.

Here's exactly what happens to your data when you use our site.

🔒 The short version

✅ We don't store your calculations. Type in numbers, get a result, close the tab — it's gone.
✅ We don't sell your data. Ever. Not to advertisers, not to data brokers, not to anyone.
✅ We don't track your personal activity. No hidden pixels, no fingerprinting, no creepy cookies.
✅ We only collect what's necessary. Mostly anonymous, aggregated data to keep the site running smoothly.

If you're in a hurry, that's the heart of it. Keep reading for the full details.

📋 What information we collect (and why)

Information you give us directly

  • Contact form submissions: If you email us at contact@calculatorpro.net or use our contact form, we'll see your name, email, and message. We only use this to reply to you and improve our tools. We never add you to marketing lists without explicit permission.
  • Bug reports or feedback: Same as above — we use it to fix things and make calculators better. That's it.

Information collected automatically

Like most websites, our servers log basic, anonymous data to keep things secure and running well:

  • Your IP address (anonymized after 7 days)
  • Browser type and version
  • Operating system
  • Pages visited and time spent (aggregated only)
  • Referring website (if you clicked a link to find us)

This data helps us:

  • Spot and fix technical errors
  • Understand which calculators are most useful
  • Protect against spam and abuse
  • Improve site speed and mobile experience

We use lightweight, privacy-focused analytics (like Plausible or Fathom) that don't use cookies or track individuals. If we ever switch tools, we'll update this policy first.

Cookies and similar technologies

We use minimal cookies:

  • 🍪 Essential cookies: Keep the site secure and functional (e.g., preventing CSRF attacks). These can't be turned off.
  • 🍪 Preference cookies (optional): Remember if you prefer dark mode or metric/imperial units. You can clear these anytime in your browser settings.
  • 🍪 Analytics cookies (optional, if enabled): Only if you consent. We use privacy-first tools that anonymize data by default.

You can manage cookie preferences via our Cookie Policy or your browser settings. We never use cookies for advertising tracking or cross-site profiling.

🧮 What happens to your calculator inputs?

This is important — so let's be crystal clear:

Your inputs are processed in your browser and never sent to our servers.

When you use a calculator on CalculatorPro.net:

  1. You type numbers into fields (like loan amount, weight, or dates)
  2. JavaScript in your browser calculates the result instantly
  3. The result appears on your screen
  4. When you close the tab, that data is gone

We don't log your inputs. We don't store your results. We don't build profiles based on what you calculate.

Exception: If you explicitly use a "Save" or "Export" feature (clearly labeled), your data may be temporarily held in your browser's local storage — still only on your device, unless you choose to email or download it.

🌍 Your rights (GDPR, CCPA, and beyond)

We respect your privacy rights, no matter where you live.

If you're in the European Economic Area (GDPR):

  • ✅ Right to access: Ask what data we hold about you
  • ✅ Right to correct: Update or fix any info we have
  • ✅ Right to delete: Request we erase your personal data
  • ✅ Right to object: Opt out of certain processing
  • ✅ Right to portability: Get your data in a usable format

If you're in California (CCPA/CPRA):

  • ✅ Right to know what personal info we collect
  • ✅ Right to delete your personal info
  • ✅ Right to opt out of "sales" (we don't sell data, but you can still opt out of sharing)
  • ✅ Right to non-discrimination for exercising your rights

How to exercise your rights

Email us at contact@calculatorpro.net with:

  • Your name
  • The email address you used (if any)
  • A brief description of your request

We'll respond within 15 business days. For verification, we may ask for a simple confirmation (like replying from the same email) — never for sensitive documents.

🔗 Third-party links and services

Our site may include:

  • Links to external resources (like government sites or educational references). We're not responsible for their privacy practices — always check their policies.
  • Embedded content (like Google Maps on our Contact page). These may set their own cookies. We only embed services that respect privacy where possible.
  • Open-source libraries (like math.js or date-fns). These run in your browser and don't transmit data to us.

We never include advertising networks that track users across sites. If we ever add non-intrusive ads to support the site, they'll be contextual (based on page content, not your behavior) and clearly disclosed.

👶 Children's privacy

CalculatorPro.net is intended for general audiences. We don't knowingly collect personal information from children under 16. If you're a parent or guardian and believe your child shared personal info with us, please contact us at contact@calculatorpro.net and we'll take steps to delete it.

🔐 How we keep your data secure

We take reasonable technical and organizational measures to protect against unauthorized access, alteration, or destruction of data:

  • All pages served over HTTPS (encrypted connection)
  • Regular security reviews of our code and dependencies
  • Minimal data retention (we delete logs after 30 days unless needed for security)
  • Access controls: Only essential team members can access submission inboxes

No system is 100% impenetrable, but we treat your trust seriously and stay vigilant.

🔄 Changes to this policy

We may update this policy occasionally — for example, if we add a new feature or if privacy laws change. When we do:

  • We'll update the "Last updated" date at the top
  • We'll highlight material changes in a brief note at the top of the page
  • We'll never make changes that reduce your rights without notice

Your continued use of CalculatorPro.net after changes means you accept the updated policy.

📬 Questions or concerns?

If anything here is unclear, or if you have a privacy question we haven't answered — please reach out. We're humans, we read every message, and we care about getting this right.
