Privacy Policy

Last updated: June 21, 2026

This Privacy Policy explains how Mengyuan Gan ("we", "us") collects, uses, and protects your information when you use RankRadar (the "Service").

1. Information we collect

• Account information — your email address and authentication details when you register.
• Usage data — the Amazon ASINs, keywords, competitor entries, and category settings you enter into the Service, plus basic logs (e.g., access times, device/browser information).
• Payment information — we do not collect or store your card details. Payments are handled by Paddle, our payment processor and Merchant of Record. We receive only limited billing metadata (such as plan, country, and subscription status).

2. How we use your information

• To provide, operate, and improve the Service.
• To manage your account, subscription, and plan limits.
• To communicate with you about your account, security, and service updates.
• To comply with legal obligations and prevent abuse.

3. Third-party services

We rely on the following providers to run the Service. Each processes data only as needed:

• Supabase — authentication and database hosting for your account and app data.
• Paddle — payment processing and billing as Merchant of Record. See Paddle's Privacy Policy.
• Netlify — website and application hosting.

4. Cookies

We use essential cookies and similar technologies to keep you logged in and to operate the Service. Paddle may set cookies during checkout. We do not use cookies to sell your data.

5. Data retention

We keep your information for as long as your account is active or as needed to provide the Service. You may request deletion of your account and associated data at any time (see Section 7).

6. Security

We use industry-standard measures to protect your data, including encryption in transit and access controls. No method of transmission or storage is completely secure, but we work to safeguard your information.

7. Your rights

Depending on your location, you may have the right to access, correct, export, or delete your personal data, and to object to or restrict certain processing. To exercise these rights, contact us at dengbin5872@gmail.com.

8. Children

The Service is not intended for anyone under 18, and we do not knowingly collect data from children.
