Privacy Policy

1. Introduction & Scope of this Policy

Welcome to MathsLover.com ("we," "our," "us," or "the Platform"). We believe that digital privacy is a fundamental human right. This Privacy Policy details our policies and practices regarding the collection, handling, disclosure, and protection of personal data and technical information when you navigate our website, utilize our mathematical calculators, explore our financial simulation algorithms, calibrate our physical Online Ruler, practice arithmetic on our Multiplication Tables Studio, or read our educational guides.

By visiting or utilizing MathsLover.com and any of its specialized sub-tools, you consent to the data collection and usage practices described in this document. If you do not agree with our principles or terms, we advise you to discontinue using our platform.

2. Our Zero-Knowledge Client-Side Processing Architecture

Unlike conventional web applications that transmit sensitive financial, health, educational, and personal data to centralized remote servers, MathsLover.com operates on a privacy-first, client-side computational architecture across all tools:

3. Specific Privacy Provisions by Tool Suite

3.1 Online Ruler & Physical Screen Measurement Utility

Our Online Ruler (accessible via /online-ruler/) allows users to measure physical objects directly against their monitor or mobile screen in centimeters, millimeters, pixels, and fractional inches.

• Zero Sensor / Camera Access: The Online Ruler does NOT access, request, initialize, or monitor your device camera, optical sensors, or microphone.
• Local Calibration Storage: When you calibrate your screen using a credit card, coin, or display diagonal, your Pixels Per Inch (PPI) factor is stored exclusively in your browser's local storage (localStorage) so you do not need to recalibrate on return visits. This value never leaves your device.
• Zero Coordinate Tracking: Interactive measurement guides, caliper bounding boxes, and 360° protractor angle positions are computed in real time on the HTML5 Canvas / SVG DOM and are instantly discarded when closed.

3.2 Multiplication Tables Studio & Interactive Learning Suites

Our Multiplication Tables Studio (accessible via /multiplication-tables/) provides visual area models, 3D flashcards, speed sprint quizzes, and printable PDF worksheet generators for learners and educators.

• Student Data Privacy (COPPA & FERPA Compliance): We do not collect, retain, or share personal data from young learners or students. Quizzes, streaks, and practice answers are evaluated 100% locally in volatile browser memory.
• Web Audio API: Sound effects and interactive auditory feedback are synthesized and triggered locally via standard browser audio APIs. No audio streams are recorded or transmitted.
• Printable Worksheets: Custom arithmetic worksheets are dynamically constructed on-the-fly in your browser DOM. No worksheet configurations or student names entered for printing are transmitted to our servers.

3.3 Progressive Web Apps (PWA) & Offline Service Workers

Certain utilities on MathsLover.com feature offline PWA support powered by Service Workers (sw.js). These service workers cache static application assets (HTML, CSS, JavaScript, icons) locally on your device to enable instant loading and offline functionality without tracking your browsing habits.

4. Information We Collect & How It Is Handled

While we do not collect or store your calculator values or measurements, modern internet infrastructure automatically processes certain technical metadata to facilitate secure web delivery and performance optimization.

4.1 Automated Technical & Server Logs

When you visit MathsLover.com, our hosting providers, Content Delivery Networks (CDNs), and firewall security systems may log non-personally identifiable diagnostic data, which may include:

• Network Identifiers: Internet Protocol (IP) address (which is anonymized and truncated wherever technically possible).
• Device & Browser Metadata: Browser type, rendering engine version, operating system architecture, screen resolution, and language settings.
• Session Timestamps: Exact date, time, duration of visit, and referring domain URL.

4.2 Aggregated Analytics & Traffic Monitoring

We analyze general aggregated trends to determine which computational tools are most popular, detect technical errors, and optimize server response times. These metrics are processed in aggregate form and cannot be reverse-engineered to identify individual users.

4.3 Voluntary Correspondence Data

If you voluntarily communicate with our technical team via email regarding bug reports, feature requests, or editorial suggestions, we retain your email address and message contents solely to respond to your inquiry and improve platform reliability.

5. Cookies, Local Storage & Tracking Technologies

MathsLover.com uses lightweight cookies and browser LocalStorage tokens to optimize your browsing workflow and preserve custom UI configurations.

6. Third-Party Advertising & Partner Disclosures

To sustain MathsLover.com as an entirely free computational resource for students, engineers, homeowners, and researchers worldwide, we partner with reputable third-party advertising networks:

• Third-party ad networks, including Google AdSense, use cookies and web beacons to serve advertisements based on your prior visits to our platform and other websites on the internet.
• Google’s use of advertising cookies enables it and its partners to serve ads based on your visit to MathsLover.com and other sites across the web.
• Users may opt out of personalized interest-based advertising at any time by configuring their preferences at Google Ads Settings or by visiting the Network Advertising Initiative Consumer Choice Page.

7. Global Compliance: GDPR, CCPA/CPRA & Statutory Rights

We are dedicated to respecting international privacy frameworks across the European Economic Area (EEA), United Kingdom, United States (including California CCPA/CPRA), Canada, and globally.

7.1 Rights Under GDPR (European Union & UK)

If you reside within the European Economic Area or UK, you are endowed with statutory data protection rights under the General Data Protection Regulation (Articles 15 through 22):

• Right of Access & Portability: You have the right to request copies of any personal metadata associated with your interactions.
• Right to Rectification & Erasure ("Right to be Forgotten"): You may request the modification or immediate erasure of any identifiable log data.
• Right to Restrict or Object to Processing: You may object to automated data processing or file a formal complaint with your regional Data Protection Authority (DPA).

7.2 California Privacy Rights (CCPA / CPRA)

Under the California Consumer Privacy Act and California Privacy Rights Act:

• Zero Data Sale Notice: We do not sell, rent, or monetize your personal information to data brokers or advertising third parties.
• Right to Non-Discrimination: Exercising your consumer privacy choices will never result in denied access, rate changes, or degraded tool functionality on MathsLover.com.

8. Data Security & Storage Standards

We maintain enterprise-grade security protocols, including 256-bit TLS/SSL encryption, automated DDoS mitigation, Content Security Policies (CSP), and secure server configurations. Although all tool computations remain local to your browser, all web assets and scripts are served over verified encrypted channels.
