Extension Identity

Hello Prompting is a Chrome Web Store extension designed to provide real-time prompt quality analysis and optimization for AI chatbot platforms.

Platforms & Permissions

Supported Platforms

The extension operates on the following AI chatbot environments:

Permissions Used

Permission Purpose
storage Used by chrome.storage.local to save user preferences, usage statistics, authentication tokens, and enhancement history.

3
Data Collection

We collect the following categories of data to fulfill the extension's single purpose of prompt optimization:

Personally Identifiable Information (PII)

We collect your email address during account signup via traditional email/password registration (via Supabase Auth) or Google OAuth. We also generate a unique User ID and a Supabase User ID to manage your account and subscription tier.

User Input & Website Content

The extension reads text typed in AI chatbot input fields. To provide context-aware optimization, it may read up to 6 recent messages in the current chat (max 600 characters each). Important: Our PrivacyPreserver class automatically scrubs PII (emails, phone numbers, credit card numbers, SSNs, IPv4 addresses) locally before any data is transmitted.

User Activity

We monitor events like input focus/blur (for UI positioning), text changes, and UI interactions (Enhance, Refine clicks). These events are processed strictly locally and are NOT transmitted to our servers.

Authentication Data

Supabase access tokens, refresh tokens, and expiry timestamps are stored locally in chrome.storage.local to maintain your session and verify subscription status.

Technical Metadata

We store usage metrics locally, including daily usage counts, session costs, your last 100 enhancement entries, feature settings, and install timestamps.

4
Data Processing

Local Processing (On-Device)

Server-Side Processing

When you request an enhancement that requires cloud processing, the scrubbed prompt is sent to our Supabase Edge Function (llm-proxy), which routes it to Google Gemini or xAI Grok APIs.

Zero-Persistence Policy: Our servers process these prompts in volatile memory and do NOT permanently store your prompt text. Account data is stored in Supabase with AES-256 encryption.
