Privacy Policy

1. Introduction

BatteryRate ("we", "our", "us") operates the website at this domain. This Privacy Policy explains how we collect, use, and protect information in connection with your use of our website and tools. We are committed to handling any data with transparency and in compliance with applicable privacy law, including the General Data Protection Regulation (GDPR) where applicable.

2. Information We Collect

BatteryRate is designed to minimize data collection. Specifically:

• Tool calculations: All EV range and charging cost calculations are performed entirely in your browser. No input data is transmitted to our servers.
• Cookies: We use a single functional cookie (key: "ck") stored in your browser's localStorage to remember your cookie consent preference. This cookie contains no personal data.
• Analytics: If analytics are enabled on this site, they may collect anonymized usage data such as page views, browser type, and approximate geographic region. No personally identifiable information is collected through analytics.
• Server logs: Our web server may automatically log standard access data including IP addresses, request paths, and timestamps. These logs are retained for up to 30 days for security and operational purposes.

3. How We Use Information

The limited information we collect is used solely for:

• Operating and maintaining the website
• Diagnosing technical issues and monitoring site security
• Understanding aggregate usage patterns to improve our tools
• Complying with legal obligations

We do not sell, rent, or share your data with third parties for marketing purposes.

4. Cookies and Local Storage

Our cookie banner uses browser localStorage — not HTTP cookies — to store your consent preference. This preference is stored only on your device and is not transmitted anywhere. You may clear this preference at any time by clearing your browser's site data for this domain.

We may use third-party services (such as Google Fonts) that may set their own cookies or log requests. Use of Google Fonts involves your browser connecting to Google's servers to download font files; this is subject to Google's own privacy policy.

5. Your Rights

If you are located in the European Economic Area or United Kingdom, you have rights under the GDPR or UK GDPR, including:

• The right to access personal data we hold about you
• The right to correct inaccurate data
• The right to request deletion of your data
• The right to object to processing
• The right to data portability
• The right to withdraw consent at any time

To exercise any of these rights, use the contact form on this page or send a written request to our registered address.

6. Data Retention

Server access logs are retained for up to 30 days and then permanently deleted. We do not retain any user-submitted calculation data, as no such data is transmitted to our servers.

7. Third-Party Services

Our website may load resources from third-party services including Google Fonts (typography) and Unsplash (photography). These services may log your IP address when your browser fetches their resources. We recommend reviewing their respective privacy policies if this is a concern.

8. Children's Privacy

Our website is not directed to children under the age of 16. We do not knowingly collect personal data from children. If you believe a child has provided us with personal data, please contact us and we will delete it promptly.

9. Changes to This Policy

We may update this Privacy Policy from time to time. The "last updated" date at the top of this page will reflect any changes. Continued use of the website after any update constitutes acceptance of the revised policy.
