Privacy Policy

1. Information We Collect

Pluto Time Calculator is designed with privacy in mind. We collect minimal data necessary to provide our service. The types of information we may process include:

• Location Data: When you use the calculator, you may provide a city name or geographic coordinates. If you use the "Use My Location" feature, your browser will request permission to access your device's GPS coordinates. This data is processed client-side in your browser and is not stored on our servers.
• Contact Information: If you use our contact form, we collect your name, email address, and message content to respond to your inquiry.
• Usage Analytics: We may collect anonymized usage statistics such as page views, referring URLs, browser type, device type, and general geographic region to improve our service.

2. How We Use Your Information

We use the information we collect for the following purposes:

• To calculate and display your personalized Pluto Time results.
• To respond to your inquiries and provide customer support.
• To analyze usage trends and improve the service's functionality and user experience.
• To maintain the security and integrity of our platform.
• To comply with legal obligations when required.

3. Client-Side Processing

Pluto Time Calculator performs all astronomical calculations directly in your web browser. Your geographic coordinates are processed locally using JavaScript and are not transmitted to our servers. The solar position algorithms run entirely on the client side, meaning your location data remains on your device. This architecture was chosen specifically to protect your privacy.

4. Cookies and Local Storage

We may use cookies and browser local storage for the following purposes:

• Essential Cookies: Required for basic site functionality, such as remembering your preferred language or time format settings.
• Analytics Cookies: Used by third-party analytics services to understand how visitors interact with our website. These cookies collect information anonymously.
• Preference Storage: Your calculator preferences (time format, last-used location) may be saved in your browser's local storage for convenience. You can clear this data at any time through your browser settings.

You can control cookie preferences through your browser settings. Disabling cookies may affect some functionality of the service.

5. Third-Party Services

We may integrate with the following types of third-party services, each with their own privacy policies:

• Hosting Provider: Our website is hosted on Vercel, which may process server logs containing IP addresses and request metadata.
• Geocoding Services: When you enter a city name, we may use external geocoding APIs to convert it to coordinates. Only the city name you typed is sent to these services.
• Analytics: We may use privacy-focused analytics tools to understand traffic patterns. These services process anonymized or pseudonymized data.
• Font Services: We load fonts from Google Fonts, which may log font requests. See Google's privacy policy for details.

6. Data Retention

We do not store your location data or calculation results on our servers. Contact form submissions are retained only as long as necessary to respond to your inquiry, typically no longer than 12 months. Anonymized analytics data may be retained for up to 26 months to identify long-term trends. You may request deletion of any personal data we hold by contacting us.

7. Your Rights

Depending on your jurisdiction, you may have the following rights regarding your personal data:

• Right of Access: Request a copy of any personal data we hold about you.
• Right to Rectification: Request correction of inaccurate personal data.
• Right to Erasure: Request deletion of your personal data ("right to be forgotten").
• Right to Restrict Processing: Request that we limit how we use your data.
• Right to Data Portability: Request your data in a structured, machine-readable format.
• Right to Object: Object to processing of your personal data for certain purposes.

To exercise any of these rights, please contact us.

8. Children's Privacy

Pluto Time Calculator is an educational tool suitable for all ages. We do not knowingly collect personal information from children under 13 (or the applicable age of consent in your jurisdiction). If you believe a child has provided us with personal information through our contact form, please contact us and we will promptly delete such information.

9. Security Measures

We implement appropriate technical and organizational measures to protect your information. Our website is served over HTTPS, ensuring all data transmitted between your browser and our servers is encrypted. Since most data processing occurs client-side, the attack surface for personal data exposure is inherently minimized. However, no method of electronic transmission or storage is 100% secure, and we cannot guarantee absolute security.

10. Changes to This Policy

We may update this Privacy Policy from time to time to reflect changes in our practices, technology, or legal requirements. Any changes will be posted on this page with an updated "Last Updated" date. We encourage you to review this policy periodically. Your continued use of the service after any modifications constitutes your acceptance of the updated policy.
