Privacy Policy

Effective Date: March 9, 2026

Calculist ("we", "our", "us") operates as a professional-grade public calculator and conversion platform. We are a privacy-first organization. This Privacy Policy explains how we handle information when you use our digital tools.

1. Information We Do Not Collect (Client-Side Privacy)

Calculist is engineered for deterministic, browser-side precision. The following inputs are processed locally on your device and are never transmitted to or stored on our servers:

• Mathematical & Loan Values: Principal amounts, interest rates, and income figures.
• Financial Data: Personal budgeting or tax inputs.
• File Data: Any values parsed for unit conversions.

All calculations are processed client-side unless a specific server-side integration is explicitly stated.

2. Information We Collect

a) Basic Usage Data: We collect anonymous usage data to maintain platform health and accuracy, including:

• Page views and navigation paths.
• Device type, browser version, and operating system.
• General geographic location (Country-level, derived from IP).
• Referrer data (how you found Calculist).

We utilize server-side verification and the Measurement Protocol to maintain analytics integrity and prevent automated bot traffic from distorting our research data.

b) Server Log Data: Our hosting infrastructure automatically logs technical metadata for security and performance optimization, including:

• IP address (for DDoS protection and rate limiting).
• Timestamp and requested URL.
• User-agent strings.

3. Cookies and Local Storage

Calculist may use cookies or local browser storage for:

• Core Functionality: Maintaining your session and tool preferences.
• Analytics: Distinguishing unique users from automated scripts.
• Preference Storage: Saving your default currency or unit selections.

We do not use cookies to track your financial inputs or personal identification. You may disable cookies in your browser settings at any time.

4. Third-Party Services

Calculist utilizes a limited number of trusted third-party providers for infrastructure:

• Hosting & CDN: To ensure global low-latency access to our tools.
• Analytics: To monitor platform stability and tool usage.
• Advertising Networks: If enabled, these networks may use cookies to deliver relevant content. We do not control third-party data practices and encourage you to review their respective policies.

5. Data Security and Integrity

As a UK-based digital utility, we employ industry-standard security protocols at the infrastructure level. Because Calculist does not maintain user accounts or store personal financial profiles, the risk of data exposure is significantly minimized.

6. International Users & GDPR Compliance

Calculist is accessible globally. For users in the UK and European Economic Area (EEA), we comply with UK GDPR and EU GDPR standards. You have the right to:

• Access any personal data we hold (typically limited to server logs).
• Request the deletion of your data.
• Object to or restrict data processing.

Since we do not store identifiable calculator input data, these rights are generally limited to our technical analytics and security logs.

7. Children's Privacy

Calculist is a technical tool not directed toward children under 13. We do not knowingly collect personal information from children.

8. Changes to This Policy

We may update this Privacy Policy to reflect changes in technical standards or legal requirements. Updates will be signaled by a revised "Effective Date" at the top of this page.
