Privacy Policy

Last updated: April 2, 2026

1. Introduction

CoinTrendz Radar ("we," "our," or "us") operates the website located at cointrendz-radar.vercel.app (the "Service"). We are committed to protecting the privacy of every person who uses our Service. This Privacy Policy explains in plain language what information we collect, how we use it, who we share it with, and what choices you have regarding your data.

Please read this policy carefully. By using the Service, you acknowledge that you have read and understood this Privacy Policy. If you do not agree with its terms, please discontinue use of the Service.

2. Information We Collect

CoinTrendz Radar is designed with privacy in mind. We do not require you to create an account, provide your name, or share any personal information in order to use the Service. The information we collect falls into two categories:

2a. Anonymous Analytics Data

When you visit CoinTrendz Radar, our analytics system may automatically record the following anonymous data points:

  • Timestamp of the visit
  • Page URL visited
  • Browser user agent string (e.g., "Chrome 120 on Windows")
  • Browser language setting
  • Approximate timezone
  • Language and theme preferences selected during the session

This data is anonymous and cannot be linked to any individual person. It is collected solely to help us understand aggregate usage patterns, monitor service health, and improve user experience.

2b. Local Storage Data

To improve your experience, CoinTrendz Radar uses your browser's localStorage (not cookies) to store your preferred theme (light or dark mode) and your preferred language. This data is stored entirely on your device and is never transmitted to our servers.

We do not collect: names, email addresses, IP addresses in personally identifiable form, financial data, location data, or any other personally identifiable information (PII).

3. How We Use the Data We Collect

The limited anonymous data we collect is used exclusively for the following purposes:

  • Monitoring overall visitor traffic volumes to understand how the Service is being used
  • Identifying popular features, pages, and language preferences to guide future improvements
  • Detecting technical errors, API failures, or performance issues that affect the user experience
  • Understanding which geographic regions use the Service to inform our multi-language support priorities

We do not use this data for advertising targeting, profiling, or any commercial purpose beyond operating and improving the Service.

4. Cookies and Tracking Technologies

CoinTrendz Radar itself does not set first-party cookies. We use browser localStorage (which is not a cookie) for storing your preferences. However, third-party services integrated into the Service may use cookies and similar tracking technologies:

Google AdSense

We display advertisements served by Google AdSense (operated by Google LLC). Google may use cookies, web beacons, and similar technologies to serve personalized ads based on your browsing history and interests. Google's advertising practices are governed by the Google Privacy Policy. You can opt out of personalized advertising from Google at any time via Google Ad Settings or through the NAI opt-out tool.

Adsterra

We also work with Adsterra as an additional advertising partner. Adsterra may use cookies and tracking pixels to deliver and measure advertisements. Their data practices are governed by the Adsterra Privacy Policy. You can manage Adsterra cookie preferences through your browser's cookie controls.

You can control cookie acceptance through your browser's settings. Blocking all cookies may affect the functionality of third-party ad content but will not impair your use of CoinTrendz Radar's core features.

5. Third-Party Services and Data Sharing

CoinTrendz Radar integrates with the following third-party services to deliver its functionality:

  • CoinGecko API: Provides cryptocurrency price, market cap, volume, and trending data. No user data is transmitted to CoinGecko.
  • Alternative.me API: Provides the Fear & Greed Index. No user data is transmitted to Alternative.me.
  • Google AdSense: Serves advertisements on the Service. May receive anonymous technical data to serve ads.
  • Adsterra: Serves advertisements on the Service. May receive anonymous technical data to serve ads.
  • Google Sheets (via webhook): Anonymous visit counts may be logged to a private Google Sheet for traffic analytics. No personally identifiable information is included in these logs.

We do not sell, rent, or trade any user data to third parties. We do not share any user information with cryptocurrency exchanges, financial institutions, or data brokers.

6. Data Retention

Anonymous visit data logged to our analytics system is retained for up to 12 months for trend analysis purposes, after which it is deleted. LocalStorage data stored on your device persists until you clear your browser's site data. We do not maintain long-term databases of personally identifiable information because we do not collect it.

7. Your Privacy Rights — GDPR and CCPA

We respect the privacy rights of all users, including those protected under the European Union's General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA).

Because CoinTrendz Radar does not collect personally identifiable information, most formal data subject rights (such as the right to access, rectify, or erase personal data) do not have direct application to our first-party data practices. However, we recognize the following rights:

  • Right to Know: You have the right to know what data we collect, which is fully described in this policy.
  • Right to Opt Out of Advertising: You can opt out of personalized advertising from Google and Adsterra using the opt-out tools linked in Section 4.
  • Right to Clear Local Data: You can delete any localStorage data at any time through your browser's site settings.

For any privacy-related inquiries or requests, please contact us at taeshinkim11@gmail.com. We will respond to all inquiries within 30 days.

8. Children's Privacy

CoinTrendz Radar is not directed at children under the age of 13. We do not knowingly collect any information from children. Cryptocurrency markets involve financial risk, and the Service is intended for users who are adults or minors with parental guidance. If you believe a child under 13 has used this Service, please contact us so we can investigate.

9. Security

We implement reasonable technical and organizational measures to protect the integrity of our Service. The Service is delivered over HTTPS (TLS encryption) to protect data in transit. Because we collect minimal data and store no PII, our security risk profile is inherently low. However, no internet-based service can guarantee absolute security, and we encourage users to use current, up-to-date browsers.

10. Changes to This Privacy Policy

We may update this Privacy Policy from time to time as the Service evolves or as legal requirements change. When we make significant changes, we will update the "Last updated" date at the top of this page. We encourage you to review this policy periodically. Your continued use of the Service after changes are posted constitutes your acceptance of the revised policy.

11. Contact
