Privacy Policy.

1. Introduction

Calculover ("we," "us," or "our") operates the website calculover.com (the "Site"). This Privacy Policy explains how we collect, use, and protect information when you visit and use our free calculator tools.

We are committed to transparency and simplicity. Calculover is designed to work without accounts, without personal data collection, and without tracking you across the web.

2. Information We Collect

2a. Information We Do NOT Collect

• No personal accounts — We never ask you to sign up, log in, or create a profile.
• No names, emails, or phone numbers — We do not collect or store any personally identifiable information (PII).
• No payment information — All tools are free. No credit cards, billing addresses, or financial data is ever requested.
• No calculator inputs — The numbers you enter into our calculators are processed entirely in your browser. They are never sent to our servers.

2b. Information Collected Automatically

We use Google Analytics (GA4) to understand how visitors use our Site. Google Analytics collects anonymous, aggregated data including:

• Pages visited and time spent on each page
• Referring website (how you found us)
• General geographic region (country/city level, not precise location)
• Device type, browser, and operating system
• Screen resolution

This data is anonymized and aggregated. It cannot be used to identify you personally. We use it solely to understand which calculators are most popular and how to improve the user experience.

2c. Local Storage

Some calculators use your browser's localStorage to save preferences or recent calculations for your convenience. This data:

• Is stored only on your device
• Is never transmitted to our servers
• Can be cleared at any time through your browser settings
• Contains no personal information

3. Cookies

Calculover itself does not set any first-party cookies. Google Analytics may set cookies (such as _ga and _gid) to distinguish unique visitors and track session activity. These are third-party cookies governed by Google's Privacy Policy.

You can opt out of Google Analytics by installing the Google Analytics Opt-out Browser Add-on or by configuring your browser to block third-party cookies.

4. How We Use Information

The anonymous analytics data we collect is used exclusively to:

• Identify which calculators are most used so we can prioritize improvements
• Understand traffic sources to reach more users who need free tools
• Detect and fix technical issues (broken pages, compatibility problems)
• Guide decisions about new calculators to build

5. Data Sharing

We do not sell, rent, trade, or share any data with third parties for marketing or advertising purposes. The only third-party service that receives any data is Google Analytics, as described above.

6. Third-Party Links

Our educational content may contain links to external resources. We are not responsible for the privacy practices of other websites. We encourage you to review the privacy policies of any site you visit through our links.

7. Children's Privacy

Calculover is a general-purpose educational tool. We do not knowingly collect any personal information from anyone, including children under 13. Since we do not collect personal data at all, there is no special risk to minors using our calculators.

8. Data Security

Since we do not collect or store personal data, the risk of a data breach affecting you is minimal. Our site is served over HTTPS to ensure secure communication between your browser and our servers. All calculator computations run locally in your browser.

9. Your Rights

Because we do not collect personal data, there is generally no personal information for us to access, correct, or delete on your behalf. If you have questions or concerns about your privacy, you are welcome to contact us.

10. Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be posted on this page with a revised effective date. We encourage you to review this policy periodically.
