Privacy Policy

1. Overview

This privacy policy explains how Ad Analyzer (“we”, “the tool”) handles your data. Ad Analyzer is a free, browser-based analytics tool for Amazon Advertising performance data. We are committed to protecting your privacy and being transparent about our data practices.

3. Data We Process

Ad Analyzer is designed with privacy in mind. We do not:

  • Collect personal data or require user accounts
  • Use cookies for tracking or analytics
  • Store your uploaded files on any server
  • Track your usage behavior or create user profiles

4. Browser-Based Processing

All file processing happens entirely within your web browser. When you upload an Amazon Advertising bulk file, the data is parsed and analyzed locally on your device using JavaScript. Your advertising data never leaves your browser and is not transmitted to our servers. When you close the browser tab, the data is discarded.

5. Hosting & Server Logs

This website is hosted on Vercel. When you visit the site, Vercel's servers automatically collect standard server log information, including:

  • Your IP address
  • Date and time of access
  • Browser type and version (user agent)
  • Referring URL

This data is collected by Vercel for operational purposes and is subject to Vercel's Privacy Policy. We do not have direct access to individual log entries.

6. AI Analysis Feature (Optional)

Ad Analyzer offers an optional AI-powered deep analysis feature. When you explicitly activate this feature, the following data is sent to a server-side API endpoint:

  • Aggregated campaign performance metrics (spend, sales, impressions, clicks, ACoS, etc.)
  • Campaign-level data for up to 50 campaigns
  • Your target ACoS setting

This data is forwarded to the Anthropic API (Claude) for analysis. The data is processed in real time to generate optimization suggestions and is not stored permanently by us or by Anthropic beyond the duration of the request. No personal data or account identifiers are included in the API request.

If you do not use the AI analysis feature, no campaign data is ever sent to any external service.

7. Third-Party Services

We use the following third-party services:

  • Vercel — Website hosting and deployment
  • Anthropic (Claude API) — AI-powered campaign analysis (only when explicitly activated by the user)

8. Your Rights Under GDPR

Under the General Data Protection Regulation (GDPR), you have the following rights:

  • Right of access — request information about data we hold about you
  • Right to rectification — request correction of inaccurate data
  • Right to erasure — request deletion of your data
  • Right to restrict processing — request limitation of data processing
  • Right to data portability — receive your data in a machine-readable format
  • Right to object — object to the processing of your data

Since we do not collect or store personal data beyond standard server logs (managed by Vercel), most of these rights are inherently fulfilled. For any requests, please contact us using the details below.
