## Privacy Policy for Ratnot

Effective Date: February 24, 2026

Ratnot ("we," "us," or "our") is committed to protecting your privacy. This Privacy Policy explains
how our Chrome Extension handles information when you use it.

### Information Collection and Use

**Core Functionality:** Ratnot does not collect, store, or transmit any personal data from your
Whatnot account or browsing history for any commercial ways. The extension processes live auction
data locally on your device to calculate Expected Value (EV) and display real-time statistics. We
also use Supabase.

**Analytics:** To improve the extension and understand which features are most useful, we collect
data to **Posthog**. This is purely for feature tracking and does not include any personal
information.

- **What we track:** Username, Feature interactions (e.g., "AI Pricing used"), onboarding progress,
  and basic environment data (Browser name/version).
- **Data Residency:** All analytics data is stored in Posthog's EU data centers

### Local Processing

All data processing happens locally on your device. We do not have a backend server that receives
your data.

### Data Storage and Local Preferences

Ratnot does not store personal or sensitive information (such as browsing history, Whatnot account
details, or bidding history).

Ratnot uses your browser's Local Storage to save:

- UI preferences (overlay positions, dimensions).
- Application state (onboarding tour completion).
- Distinct id for Posthog

This data is stored locally on your device to ensure a consistent experience across sessions and is
never transmitted to our servers. Clipboard Data: We only access the clipboard when the AI Pricing
tool is active to import user-copied values. This data is processed locally and never stored.

### Third-Party Sharing

We do not sell, trade, or share your data with third parties for marketing or advertising. Our only
third-party service provider is Posthog for analytics and Supabase for extending core feature.

### Changes to This Policy

We may update this policy from time to time. Any changes will be reflected by the "Effective Date"
at the top of this page
