Privacy Policy & Data Transparency
At EVCarCalculator.com, we believe privacy is a fundamental human right. Our architecture is deliberately engineered to process calculations in client-side memory so that your financial information remains exclusively yours.
1. Core Architectural Privacy Principle
When you adjust sliders, select vehicles, or toggle federal tax credits on EVCarCalculator.com, all mathematical operations execute within your device's browser memory (Client-Side Execution). Unlike traditional web tools that send every form input over the network to a database, our calculation engine operates entirely on your device. We do not inspect, collect, or store your personalized calculations.
2. Information We Do Not Collect
We do not collect or maintain records of:
- Your personal driving distances or daily commute parameters.
- Your utility provider account details or specific monthly power bills.
- Your household tax filing status, adjusted gross income (AGI), or IRA tax credit eligibility.
- Your vehicle VIN numbers, purchase receipts, or financial loan terms.
- Any banking, payment card, or financial account credentials.
3. Information Collected Automatically (Server Telemetry)
Like virtually all standard web infrastructure, our hosting servers automatically record routine, non-identifying technical metadata when a web page is requested. This technical metadata may include:
- Browser & Device Type: User-agent string, operating system, and viewport size to ensure correct rendering.
- Network Diagnostics: IP address (anonymized for security logs), requested resource URI, timestamp, and HTTP response status code.
- Security & DDoS Mitigation: Automated rate-limiting logs used exclusively to protect server uptime and prevent malicious denial-of-service attempts.
This technical log data is retained temporarily for security auditing purposes and is automatically purged on a rolling cycle. It is never linked to individual identity profiles.
4. Local Storage & Cookies
We use minimal, strictly functional client-side storage (such as browser localStorage) strictly to preserve your user interface preferences (for instance, remembering whether you last calibrated in miles or kilometers, or saving your custom slider state during your session).
You can clear your local browser cache and storage at any time via your browser settings without affecting the core functionality of the website.
5. Contact Form & Voluntary Communications
If you voluntarily reach out to our engineering team through our Contact Us page or email us at contact@evcarcalculator.com, we collect only the contact details you supply (such as your name, email address, and message content).
We utilize this information solely to respond to your specific inquiry, model addition suggestion, or technical feedback. We never sell, rent, or distribute your email address to commercial marketing lists or advertisers.
6. Global Compliance (GDPR, UK GDPR, CCPA / CPRA)
Regardless of where you reside—in the European Economic Area (EEA), United Kingdom, California, Canada, or elsewhere—we uphold global data privacy standards:
- Right to Know & Access: You may request information regarding any personal data we hold (e.g. past support emails).
- Right to Erasure / Deletion: You may request the immediate deletion of any direct correspondence records.
- Right to Non-Discrimination: We provide full, unrestricted access to all calculator tools and documentation without requiring account creation or personal data surrender.
- "Do Not Sell My Personal Information": We do not sell or monetize personal data in any form.
7. External Third-Party Links
Our website provides direct references to official regulatory and energy benchmarks (including the U.S. EPA FuelEconomy.gov, EIA.gov, IRS.gov, and AAA). When you navigate to an external third-party site, their respective privacy policies govern your interaction. We encourage you to review their policies.
8. Changes & Inquiries
We may periodically update this Privacy Policy to reflect advancements in technology or statutory requirements. Any revisions will be published on this page with an updated revision date.
For any questions or privacy concerns, please submit an inquiry via our Contact Portal or email our team at privacy@evcarcalculator.com.
