Privacy Policy

Last updated: January 2025

1. Information We Collect

When you use SentiChain services, we may collect:

• Account Information: Email address, name, and user ID when you register for API access
• Usage Data: API requests, endpoints accessed, and timestamps
• Technical Data: IP address, browser type, and device information

2. How We Use Your Information

We use collected information to:

• Provide and maintain our services
• Process API requests and manage your account
• Monitor usage and prevent abuse
• Improve our services and develop new features
• Communicate with you about service updates

3. Data on the Blockchain

The SentiChain blockchain stores sentiment analysis embeddings, not raw social media content. Embeddings are mathematical representations that do not directly reveal the original text. However, the Aparecium model can reconstruct approximate text from embeddings.

Data stored on the blockchain is public and immutable. Transaction metadata including timestamps and post links are visible to all users.

4. Data Sharing

We do not sell your personal information. We may share data:

• With service providers who assist in operating our services
• When required by law or legal process
• To protect the rights and safety of SentiChain and its users

5. Data Retention

Account information is retained as long as your account is active. You may request deletion of your account by contacting us. Note that blockchain data is immutable and cannot be deleted.

6. Security

We implement appropriate technical and organizational measures to protect your personal information. However, no method of transmission over the internet is completely secure.

7. Your Rights

Depending on your location, you may have rights to:

• Access your personal information
• Correct inaccurate information
• Request deletion of your information
• Object to processing of your information
• Data portability

8. Cookies

We use minimal cookies necessary for the operation of our services. We do not use tracking cookies or third-party analytics that track users across websites.

9. Changes to This Policy

We may update this privacy policy from time to time. We will notify you of any significant changes by posting the new policy on this page.
