Privacy Policy

1. Introduction

Welcome to Prasun Tools (accessible at https://tools.prasunbarua.com), owned and operated by Prasun Barua ("we", "our", or "us"). We are deeply committed to protecting your privacy and ensuring transparency regarding how information is handled when you visit our website, utilize our technical calculators, and interact with our platform.

This Privacy Policy outlines our data collection practices, security protocols, and your privacy rights under internationally recognized privacy principles and applicable data protection requirements.

2. Effective Date and Version

This Privacy Policy is effective as of August 6, 2026. We regularly review our compliance procedures and operational policies to adapt to evolving technical standards and regulatory requirements.

3. Information We Collect

Prasun Tools is structured to function with minimal data collection. We collect information through the following methods:

Information Provided Voluntarily

We do not require user accounts, registration, or login credentials to access our calculators. Personal information is collected only when you choose to provide it directly, such as:

• Inquiries, bug reports, or feedback sent through our contact channels.
• Direct correspondence addressed to our support or administrative emails.

Automatically Logged Technical Data

When you browse our platform, our hosting infrastructure and security providers automatically record standard technical log data. This server log information may include:

• Your device's Internet Protocol (IP) address.
• Browser type, version, and language settings.
• Operating system and device metadata.
• Referring web pages, exit pages, and clickstream data.
• Timestamps and duration of visit.

4. Information We Do Not Collect

To uphold privacy standards, Prasun Tools typically does not collect or store:

• User account passwords, personal profiles, or login credentials unless account registration features are explicitly utilized.
• Sensitive personal identification numbers or financial account details (unless explicitly processed by designated third-party payment gateways for paid subscriptions or services).
• Proprietary calculation inputs, formulas, or raw data entered into standard client-side engineering tools, unless a specific feature explicitly requires server-side processing.

5. How We Use Information

The limited data we collect is utilized strictly for operational, security, and analytical purposes:

• To maintain, operate, and optimize the performance of our web platform and calculators.
• To protect against security threats, denial-of-service attacks, and fraudulent activity via security infrastructure.
• To analyze aggregate traffic trends and user behavior to determine popular tools and improve user experience.
• To respond directly to user inquiries, technical feedback, or support requests.

6. Browser-Based Tool Processing

A core architectural feature of Prasun Tools is its reliance on browser-based calculations and client-side processing. The parameters, measurements, and numerical inputs you enter into our engineering calculators are executed locally within your web browser using client-side scripting (JavaScript).

For client-side calculators, calculation data remains within your browser environment and is not transmitted to our servers unless required by a specific feature or service.

7. Cookies and Local Storage

We utilize browser local storage solely for functional interface preferences, such as remembering whether you selected a light or dark display theme. We do not use persistent local tracking for intrusive profiling.

Third-party service providers integrated into our platform (such as analytics and advertising networks) may place cookies on your browser to collect standardized traffic and interaction data in accordance with their respective policies.

8. Google Analytics

We utilize Google Analytics to evaluate aggregate visitor traffic, page views, and platform usage patterns. This service collects usage statistics, device information, and interaction data through cookies and similar technologies to help us analyze traffic patterns and improve our utility offerings, in accordance with Google's privacy practices.

You can opt out of Google Analytics tracking across all websites by installing the Google Analytics Opt-out Browser Add-on.

9. Google AdSense and Advertising

To support the free availability and ongoing maintenance of Prasun Tools, we display advertisements served by Google AdSense. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other internet properties.

Google's use of advertising cookies enables it and its partners to serve ads based on your visit to our site and/or other sites on the Internet. You may manage or opt out of personalized advertising by visiting Google Ad Settings or reviewing the Google Advertising Privacy Policy.

10. Third-Party Services

Our platform integrates specialized third-party services to deliver seamless performance, security, and infrastructure support:

• Cloudflare: Provides domain name resolution, edge caching, DDoS mitigation, and web security protection.
• GitHub Pages: Hosts static web assets and file delivery network infrastructure.
• Google Analytics: Measures audience engagement and aggregated web traffic.
• Google AdSense: Delivers contextual and personalized advertisements.

11. Hosting and Security Infrastructure

Prasun Tools is hosted securely on modern static infrastructure and protected via Cloudflare edge networks. Connection traffic is encrypted using industry-standard Transport Layer Security (HTTPS) to safeguard data in transit between your browser and our servers.

12. External Links

Our website may contain links to external third-party websites or reference resources not operated by us. We exercise no control over, and assume no responsibility for, the content, privacy policies, or practices of any third-party sites or services.

13. Data Security

We implement robust technical safeguards, secure protocols, and routine administrative checks to protect information against unauthorized access, alteration, disclosure, or destruction. However, no method of electronic transmission over the internet or digital storage is 100% secure, and we cannot guarantee absolute data security.

14. User Rights and Controls

Visitors maintain full autonomy over their privacy preferences through standard browser capabilities and configuration options:

• Cookie Management: You can configure your browser to block, restrict, or delete cookies at any time.
• Local Storage Control: You can clear local storage cache via your browser developer settings or privacy menus.
• Opt-Out Extensions: You may use privacy-focused extensions, script blockers, or ad-blocking utilities to manage tracking preferences.

If you believe a minor has provided personal information to us, please contact us immediately for prompt deletion.
