Privacy Policy & Reader Data Protection
Effective Date: January 1, 2026
1. Commitment to Privacy & Technical Telemetry
At ChargeTier ("we," "us," or "our"), available at www.chargetier.com, protecting the privacy and security of our readers is a foundational priority. We collect minimal data necessary to deliver fast, responsive, and secure content across desktop and mobile viewports.
When you navigate our Website, our hosting servers automatically collect standard non-personally identifiable technical log files, including:
- Network Log Information: Internet Protocol (IP) address, operating system, browser user-agent string, preferred language settings, referring/exit web pages, and timestamp of request.
- Performance Metrics: Page response times, Core Web Vitals diagnostic metrics, and client-side rendering errors.
2. Local Browser-Side Processing of Interactive Calculators
ChargeTier hosts interactive calculation tools, including the EV Charging & Infrastructure Sizer, TCO Calculator, and Voltage Drop Engine.
All numerical inputs provided to our interactive calculators (e.g., commute mileage, utility electric rates, vehicle model selections) are processed locally within your web browser using client-side JavaScript.
3. Cookies, Tracking Pixels & Affiliate Network Attribution
ChargeTier participates in reader-supported affiliate marketing programs, including the Amazon Services LLC Associates Program and direct manufacturer referral networks. When you click an outbound referral link to a merchant:
- Merchant Attribution Cookies: Third-party merchant platforms (such as Amazon.com, Home Depot, Autel, or Emporia) place a temporary tracking cookie on your browser. This cookie records that your visit originated from ChargeTier so the seller can attribute sales commissions.
- Zero Access to Financial Information: These attribution cookies do NOT grant ChargeTier access to your credit card details, financial data, billing address, or personal purchasing history.
- Cookie Management & Browser Disabling: You can block or clear tracking cookies at any time through your web browser preferences without restricting your access to our technical guides or calculation tools.
4. Reader Rights Under GDPR & CCPA / CPRA
If you reside in the European Economic Area (EEA), United Kingdom, or California, you hold specific data protection rights under the General Data Protection Regulation (GDPR) and California Consumer Privacy Act (CCPA/CPRA):
- Right to Know & Access: You hold the right to request disclosure of the categories and specific pieces of personal information collected (if any).
- Right to Request Deletion: You hold the right to request deletion of personal information submitted to us via contact or quote forms.
- We Do Not Sell Personal Data: ChargeTier does NOT sell, trade, or rent personal reader information to third-party data brokers.
5. Infrastructure Security & Data Encryption
All connections to www.chargetier.com are encrypted using HTTPS (SSL/TLS) encryption.
6. Third-Party Websites & Outbound Links
Our guides link to external resources and merchant stores. We have no operational control over the content, privacy practices, or cookie policies of third-party domains. We encourage you to review the privacy notices of external websites you visit.
