Privacy Policy

Last updated: January 2026

        Summary: Aletheia is privacy-first. We only access text you explicitly select, we don't track you, and we don't sell your data.
      

1. What We Collect

When you select text and choose "Explain with AI", the following is sent to our servers:

The text you select
The surrounding text
The page URL where you selected it

We do not collect:

Your browsing history across sites
Personal information
Any data without your explicit action

2. How We Process Your Data

Your text is analyzed using AWS Bedrock (Amazon Nova AI). AWS Bedrock:

Does not train on your prompts
Does not store your data beyond processing
Processes data in secure, isolated environments

3. Data Retention

Submitted text is stored for 30 days to enable features like conversation history, then automatically deleted. We never sell your data or use it to train AI models.

4. Browser Permissions

Aletheia requests only the permissions strictly necessary:

ActiveTab: Access only the current tab when you invoke the extension
ContextMenus: Add "Explain with AI" to your right-click menu
Storage: Save your preferences locally

We cannot access your browsing history, other tabs, or any data you don't explicitly select.

5. Your Rights (GDPR/CCPA)

You have the right to:

Request deletion of your data at any time
Access information about what data we hold
Data portability

Data is also automatically purged after 30 days.

6. Third-Party Services

We use the following third-party services:

AWS Bedrock: AI processing (Amazon Web Services)

We do not use analytics, advertising networks, or tracking services.
