Privacy Policy

2. Information We May Collect

When you navigate our site, we may automatically collect limited technical data required for website stability, DDoS mitigation, and performance optimization:

• Log and Server Data: IP address, browser type, operating system, referring URLs, and timestamp of request.
• Display & Functional Preferences: Local storage settings to remember your preferred interface options (such as Dark/Light theme mode, unit selection like Metric vs Imperial, and selected language).
• Voluntary Communications: If you contact us via email, we receive your email address and any details you provide in your message.

3. Cookies and Local Storage

We use minimal cookies and browser local storage strictly to ensure site functionality. We do not use intrusive tracking cookies to build personal surveillance profiles. You can configure your browser to reject all cookies, though some preferences (like your dark mode choice) may need to be reset each visit.

4. European General Data Protection Regulation (GDPR)

For users residing in the European Economic Area (EEA), the United Kingdom, or Switzerland, you enjoy statutory rights under the GDPR, including:

• The right to access data we hold about you.
• The right to rectification or erasure (“right to be forgotten”).
• The right to restrict or object to processing.
• The right to lodge a complaint with your local data protection supervisory authority.

Because we do not maintain accounts or record individual calculation histories, we hold virtually zero identifying data on visitors.

5. California Consumer Privacy Rights (CCPA / CPRA)

California consumers have specific rights regarding personal information. Under the CCPA and CPRA:

• We Do Not Sell Personal Information: We have never sold, rented, or bartered user personal information to data brokers or advertisers, and we will never do so.
• Right to Know & Delete: You have the right to request what personal information is collected and to request deletion.
• Non-Discrimination: We will never penalize or deny services to any user who exercises their privacy rights.

6. Children’s Privacy (COPPA)

Our calculators and educational resources are intended for general audiences. We do not knowingly collect personal identifiable information from children under the age of 13. If you believe a child has provided us with personal information, please contact us and we will promptly remove it.

7. Data Security

We implement modern encryption standards, including 256-bit TLS/HTTPS encryption across every page, subresource, and asset on calculatorscale.com to protect all network interactions from interception or tampering.
