# Nugget — Privacy Policy

**Last updated: March 2, 2026**

## Overview
Nugget is a Chrome extension that automatically captures and saves AI conversations locally on your device. Your privacy is important to us.

## Data Collection
Nugget does **NOT** collect, transmit, or store any personal data on external servers.

### What Nugget stores locally:
- Questions and answers from AI conversations (Claude, ChatGPT, Gemini, Perplexity)
- User-created tags, notes, and collections
- Extension settings and preferences
- Pro purchase status (via ExtensionPay)
- Trial activation timestamp (stored in Chrome sync storage, tied to your Google account)

### What Nugget does NOT collect:
- Personal identification information (name, email, address)
- Browsing history outside of supported AI platforms
- Analytics or tracking data
- Cookies or fingerprinting data

## Data Storage
All conversation data is stored locally using Chrome's `chrome.storage.local` API. Trial status is stored in `chrome.storage.sync` (synced across your Chrome browsers via your Google account).

No data is sent to any external server except:
- **Telegram** (only if you configure Telegram integration in Settings)
- **Webhook** (only if you configure a custom webhook URL in Settings)
- **ExtensionPay** (for Pro purchase verification only)

## Third-Party Services
- **ExtensionPay** (extensionpay.com): Used solely for processing Pro purchases. ExtensionPay handles payment through the Chrome Web Store. See [ExtensionPay's privacy policy](https://extensionpay.com/privacy).

## Data Deletion
You can delete all stored data at any time from the extension's Settings page ("Delete all data" option). Uninstalling the extension also removes all locally stored data.
