Privacy Policy

SlabCalc respects your privacy. This policy explains how we collect, use, and protect your information.

1. Information We Collect

Information You Provide

SlabCalc does not require account creation or personal information to use our calculators. We do not collect names, email addresses, phone numbers, or other personally identifiable information unless you voluntarily provide it (e.g., through contact forms or feedback).

Automatically Collected Information

When you visit SlabCalc, we may automatically collect:

• Usage Data: Pages visited, time spent, clicks, and interactions
• Device Information: Browser type, operating system, device type
• Technical Data: IP address, referral source, access times
• Calculator Inputs: Dimensions and values entered (stored locally in your browser only)

2. How We Use Your Information

We use collected information to:

• Provide and improve our calculators and content
• Analyze usage patterns and optimize user experience
• Monitor site performance and fix technical issues
• Understand which features are most useful
• Detect and prevent abuse or security issues

3. Cookies and Tracking

First-Party Cookies

We use cookies to remember your preferences (e.g., measurement units, recent calculations) and improve your experience. These are stored locally in your browser and can be cleared at any time.

Analytics

We may use analytics services (such as Google Analytics or similar tools) to understand how visitors use our site. These services may use cookies and collect data such as page views, session duration, and referral sources. Analytics data is aggregated and anonymized.

Managing Cookies

You can control cookies through your browser settings. Disabling cookies may affect some functionality but will not prevent you from using our calculators.

4. Data Storage and Calculations

Your calculations are performed in your browser. Nothing you type is sent to our servers in order to produce your result.

Separately, we keep an anonymous record of completed calculations so we can understand how the site is used and publish aggregate research about typical concrete projects. Each record contains only the project type, shape, unit system, dimensions, thickness and resulting volume, together with a coarse location — country and state or region only, derived from network routing information.

These records contain no information that identifies you. We do not store your IP address, your city, your name, your email address, a device identifier, or any session or cookie identifier alongside them, and there is no key that would let us link a record back to you or to your visit. They cannot be traced to an individual, and we do not attempt to do so.

5. Third-Party Services

SlabCalc may use third-party services that have access to certain data:

• Hosting Provider: Hosts our website and may log access data
• Analytics Services: Collect usage statistics (anonymized)
• Content Delivery Networks (CDNs): Deliver assets faster

These services have their own privacy policies. We do not sell, rent, or share your personal information with third parties for marketing purposes.

6. Data Security

We implement reasonable security measures to protect against unauthorized access, alteration, or destruction of data. However, no internet transmission is 100% secure. We cannot guarantee absolute security of information transmitted to or stored on our systems.

7. Children's Privacy

SlabCalc is not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us.

8. Your Rights

You have the right to:

• Access information we have about you
• Request deletion of your information
• Opt out of analytics tracking (via browser settings)
• Clear your browser cookies and local storage at any time

9. Data Retention

We do not collect or retain personal information. The anonymous calculation records described in Section 4 are kept for approximately 400 days and then expire automatically. Analytics data is retained according to our analytics provider's retention policies (typically 14-26 months).

10. International Users

SlabCalc is operated from the United States. If you access our site from outside the US, your information may be transferred to, stored, and processed in the US. By using SlabCalc, you consent to this transfer.

11. Changes to This Policy

We may update this Privacy Policy periodically. Changes will be posted on this page with an updated "Last Updated" date. Continued use of SlabCalc after changes constitutes acceptance of the updated policy.
