Privacy Policy

Universal AI Enhancer — Prompt Engineer

Last updated: April 2026

Universal AI Enhancer is a Chrome extension built by PixelForgeHub (Yogesh Nichal). This policy explains how the extension handles your data.

Summary

This extension has no backend. No data is collected on any server operated by PixelForgeHub. All prompts, settings, and history stay on your device, except when you explicitly choose to enhance a prompt — in which case the text is sent either to Chrome's on-device AI (Gemini Nano, fully local) or, if you provided one, to Google's Gemini API using your own key.

What We Store Locally

The following is saved in Chrome's local extension storage on your device only. Nothing is transmitted to PixelForgeHub:

• Your Gemini API key (only if you choose to provide one)
• Your UI language preference (English, Vietnamese, Chinese, Korean, Spanish, or Japanese)
• A daily enhancement counter, reset every 24 hours
• Your last 10 enhancements (first 50 characters of input + first 80 characters of output) for quick re-use
• The current draft of what you're typing in the popup, so it's preserved if you close the popup

All stored data can be cleared by removing the extension from Chrome.

Where Your Prompts Go

• Chrome Gemini Nano (NPU) path: When your Chrome build supports on-device AI, enhancement runs entirely locally on your CPU/GPU. No data leaves your browser.
• Your Gemini API key path: If Chrome NPU is unavailable, the extension calls generativelanguage.googleapis.com directly from your browser, using your own API key. PixelForgeHub never receives this request. Google's Gemini API terms and privacy policy govern that interaction.

Permissions Explained

• storage: Saves your API key, UI language, quota counter, and history entries locally on your device.
• activeTab: Reads text you have explicitly selected on the current tab, only when you click “Enhance Prompt” in the right-click menu. No background access to any other tab.
• contextMenus: Adds a single “✨ Enhance Prompt” item to the right-click menu when you have text highlighted, so you can enhance selected text without opening the popup first.
• sidePanel: Lets you pin the enhancer in Chrome's side panel to keep it open while working in another tab (e.g., ChatGPT, Claude).

Host Permissions

None requested. The extension does not request access to any website. Enhancement requests to Google's Gemini API are made with standard fetch() calls, which do not require host permissions in Manifest V3.

What We Do Not Do

• We do not collect analytics or telemetry.
• We do not require an account, sign-up, or login.
• We do not sell or share any user data with third parties.
• We do not track your browsing history or read content from pages you visit (except text you explicitly select and right-click to enhance).
• We do not transfer data for advertising, credit scoring, or any purpose unrelated to the extension's single function of enhancing prompts.

Third-Party Services

When you choose to use your own Gemini API key, your enhancement requests go directly from your browser to Google's Gemini API (generativelanguage.googleapis.com). Your use of that API is governed by Google's Privacy Policy and Gemini API Terms. PixelForgeHub is not a party to that interaction and does not receive the prompt or the response.

Changes to This Policy

If we update this policy we'll change the “Last updated” date at the top. Material changes (e.g., any new data collection) will be communicated in the extension's release notes on the Chrome Web Store.
