Privacy Policy
Effective Date: January 1, 2026 • Last Revised: 2026
1. Absolute Client-Side Financial Privacy
At EtsyCalculator.com, we respect the proprietary nature of your e-commerce operations. All product prices, supplier costs, shipping fees, advertising expenditures, and profit calculations entered into any of our calculators are processed 100% locally within your device's web browser using client-side JavaScript.
We do not transmit, capture, log, or sell your product pricing or financial margins to any server or third party. If you utilize our local calculation history feature, that history is stored exclusively in your browser's private localStorage and never touches our backend.
2. Web Analytics & Usage Telemetry
We may collect non-personally identifiable diagnostic and performance data using standard web server access logs and privacy-centric analytics (e.g. Google Analytics). This data includes browser type, operating system, referring URL, time of visit, and pages viewed. This telemetry helps us diagnose software bugs, optimize page loading speed, and refine user experience.
3. Cookies & Advertising Partners
We use essential cookies to maintain user preferences (such as dark mode versus light mode toggles). Third-party advertising networks (such as Google AdSense) may utilize cookies, scripts, and web beacons to serve contextually relevant advertisements based on prior visits to our site or other websites across the Internet. You can manage or disable advertising cookies at any time via your browser settings or by visiting the Digital Advertising Alliance Consumer Choice page.
4. GDPR & CCPA Compliance
Under the EU General Data Protection Regulation (GDPR) and California Consumer Privacy Act (CCPA), visitors have rights regarding data access, rectification, and erasure. Because we do not mandate account registration, collect credit card details, or store personal profiles on our servers, we hold no personal identifying records of visitors. If you contact our support desk via email or our contact form, your email address is used exclusively to respond to your inquiry and is never shared.
