Privacy Policy
At Zernar, your privacy is not merely a legal afterthought or a compliance checkbox—it is the foundational engineering principle of our entire digital platform. This comprehensive Privacy Policy outlines our transparent, uncompromising approach to data handling. It details exactly what information remains strictly local to your device, what minimal telemetry is collected for edge-network infrastructure purposes, and your sovereign rights as a user navigating our utility tools in the modern era of data collection.
1. Zero-Data Processing & Client-Side Architecture
The cornerstone of the Zernar ecosystem is our 100% client-side, zero-server execution model. When you utilize any of our professional-grade calculators (spanning our Health, Automotive, or PC hardware hubs), the sensitive variables you enter are processed entirely by your web browser's local memory (RAM) utilizing advanced JavaScript and WebAssembly (Wasm) engines. We physically do not transmit your input payloads across the open internet. We do not store your financial amortizations or health metrics in backend SQL or NoSQL databases. We literally cannot see, share, or monetize the numbers you type into our fields because that data never touches our servers. You can even disconnect your device from the internet (airplane mode) after loading a tool, and it will continue to compute flawlessly. This 'trustless' architecture guarantees absolute, cryptographic-grade privacy for your personal estimations.
2. Essential Server Logs and Infrastructure Data
While our utility tools collect zero user data, the global Edge CDN (Content Delivery Network) infrastructure that securely hosts our website must process standard internet requests to function. Like all modern, secure web applications, our hosting provider automatically generates transient, anonymized access logs during the standard TCP/IP handshake. These logs may include your masked IP address, browser User-Agent strings, operating system, and TLS connection timestamps. This telemetry is strictly operational: it is fundamentally necessary to prevent Distributed Denial of Service (DDoS) attacks, mitigate malicious botnets, enforce API rate limiting, and ensure server stability. These technical logs are heavily restricted, automatically rotated, and are never used to identify you personally, nor can they ever be linked to your local activity within the calculators.
3. Third-Party Integrations, Advertising, and Analytics
To democratize access to our tools and maintain our global infrastructure completely free of charge, Zernar utilizes carefully selected third-party services. We implement Google Analytics via anonymized tags to understand aggregated, macroscopic traffic trends—such as regional tool popularity and Core Web Vitals—without ever fingerprinting individual users. Furthermore, we support the platform using Google AdSense. Google and its authorized ad-tech vendors utilize persistent cookies to serve contextual or personalized advertisements based on your browsing history. It is crucial to understand that these third-party scripts operate inside strict browser sandboxes; they absolutely cannot read, access, or intercept the private variables you input into our calculators. You retain total sovereignty over your ad experience and can instantly opt out of personalized behavioral tracking via Google's My Ad Center or your device's native anti-tracking settings.
4. Your Rights and Contact Information
Under stringent global privacy frameworks—including the European Union's GDPR, the UK Data Protection Act, and California's CCPA/CPRA—you are granted explicit, enforceable rights concerning your digital footprint. Because Zernar inherently operates on a zero-data architecture, there is no centralized account to delete or personal data archive to export from our backend. If you have any inquiries regarding our zero-server architecture, our security protocols, or wish to discuss this policy with our Data Protection team, we are ready to assist you. Please reach out to us directly at privacy@zernar.com, and we will respond with the utmost priority.
