Scope

This policy covers the Prompt Enhancer Chrome extension and what it does with information when you use it on supported websites.

The portfolio website and the extension are separate. This page is about the extension only.

Data we process and store

Your prompts stay on your device. The extension never sends them to external servers.

Processed on device

When you trigger enhancement, the extension reads your prompt from the input field and processes it locally using Chrome's built-in Gemini Nano model. Nothing leaves your device.

Stored locally on device

The extension stores up to 20 enhanced prompts in your Recent Enhancements history (saved when you copy or insert), plus your theme preference. All of it stays in your browser's local storage and is never transmitted. You can clear it any time from the popup.

Extension state tracking

The extension saves a version number to know when to show update notices. That's it, and it stays local.

Not collected

The extension doesn't collect your name, email, address, payment details, health data, location, or browsing history. No personal information leaves your device.

How the extension works

There are two ways to enhance a prompt. Both run entirely on your device.

Instant Enhancement

  1. An Enhance button appears near the text box on supported sites: ChatGPT, Gemini, Claude, and Perplexity.
  2. Click "Instant Enhance" or press Ctrl+Shift+E. The extension reads your prompt from the input field.
  3. Chrome's Gemini Nano processes it locally and streams the result in real time.
  4. Insert it into the text box, copy it, or regenerate for a different take.

Add Context Mode

  1. Click "Add Context" or press Ctrl+Shift+D to open a draggable context box with your original prompt.
  2. The AI asks a clarifying question. You answer in the context box.
  3. It then generates a tailored prompt. Regenerate keeps your answers, so you don't start from scratch.

History saves when you click "Copy" or "Insert", up to 20 prompts stored locally.

Privacy guarantee

Enhancement happens on your device. The extension doesn't send your prompts to any external API or server. Everything runs through Chrome's local AI.

Permissions explained

The extension requests the following Chrome permissions:

alarms

Used to keep the background service worker responsive for processing prompt enhancement requests. Not used for tracking, analytics, or data collection.

storage

Used to store local extension state: recent enhanced prompts, theme preference, and version tracking for update notices. This data stays in your browser and is never transmitted.

host_permissions

Allows the extension to run only on supported sites so it can inject the Enhance button and read the prompt from the input field when you trigger enhancement.

Supported sites only:

  • chatgpt.com
  • gemini.google.com
  • claude.ai
  • www.perplexity.ai

The extension cannot access any websites outside of these domains.

Data sharing

We don't sell or share your prompts or personal data.

Because everything runs locally, there's no prompt data to share even if we wanted to.

No data leaves your device during enhancement.

Data retention

Enhanced prompts in your history are retained locally until you:

  • Clear the history using the "Clear All" button in the extension popup
  • Uninstall the extension (which removes all extension data)
  • Clear your browser's extension data manually

The extension keeps your 20 most recent enhanced prompts. Anything older gets cleared automatically.

Your choices and controls

You have full control over your data:

  • Clear history:Use the "Clear All" button in the extension popup to delete all saved enhanced prompts instantly.
  • Uninstall: Remove the extension at any time from chrome://extensions to delete all extension data from your browser.
  • Control AI model:Manage Chrome's on-device AI model availability through chrome://flags and chrome://components.

Third-party services

No analytics, no tracking pixels, no external APIs.

Chrome may download or update the Gemini Nano model as part of its built-in AI feature. That's Chrome's behavior, not the extension sending your prompts somewhere.

Chrome Web Store compliance: The use of information received from Google APIs adheres to the Chrome Web Store User Data Policy, including the Limited Use requirements.

Children's privacy

The extension doesn't collect personal information from anyone, including children under 13. Since everything stays on your device, there's no data collection to speak of for any age group.

Changes to this policy

If the extension changes in ways that affect this policy, we'll update this page and bump the date at the top.

Using the extension after an update means you're OK with the revised policy.
