# UX HeatGrid Privacy Policy

Last updated: October 10, 2026

UX HeatGrid is a Chrome extension that inspects the page you are viewing. It analyses page structure (**Predict**) and, only when you start it, records your own interaction with the page (**Record**). All processing happens locally in your browser.

## Summary

- UX HeatGrid makes no network requests. It has no servers, analytics, advertising, telemetry or tracking code.
- Nothing UX HeatGrid processes is sent to the developer or to any third party.
- UX HeatGrid runs only on a tab after you click its toolbar icon, and only Predict or Record when you start them.
- Form values, passwords, typed text and the keys you press are never read.
- Recorded data is temporary and is removed when you clear it, start a new recording, close the tab or end the browser session.

## What UX HeatGrid processes

**Page information (Predict and Record).** When you start Predict or Record, UX HeatGrid reads the page's structure in your browser: interactive controls, their size, position, computed style and colour contrast, and nearby headings and landmarks. To name controls it uses accessible labels — `aria-label`, `aria-labelledby`, an associated `<label>`, `title`, `alt`, `placeholder` and visible text of the control itself. It never reads the content of form fields or editable regions, including when they sit inside a label.

**Interaction data (Record only).** While a recording is running, UX HeatGrid captures your:

- pointer positions (sampled) and the control under the pointer
- clicks, and activations of controls by keyboard or assistive technology (it registers *that* a control was activated, not which key was pressed)
- hover and focus on controls
- how long controls were visible in the viewport, and scroll depth

**Page identity (Record only).** For each recorded page it keeps the page's origin and path and a title shortened to 80 characters. Query strings and URL fragments are not kept.

**Side panel.** The side panel shows the current tab's title and domain, which Chrome provides after you click the toolbar icon.

## Where data is kept

| Data | Where | Removed when |
| --- | --- | --- |
| Prediction results | Memory of the page's UX HeatGrid runtime | You reset it, the page is reloaded or navigated away, or the tab closes |
| Completed recording report | Memory of the page's UX HeatGrid runtime | You clear it, start a new recording, navigate away, or the tab closes |
| Recording segments during multi-page sessions | `chrome.storage.session` | The recording is stopped (collected into the report), cleared or replaced, or the tab closes |
| Small per-tab status record (session state and totals, no page content) | `chrome.storage.session` | The tab closes |
| Side-panel theme choice (System, Light or Dark) | The side panel's local storage on this device | UX HeatGrid is uninstalled |

`chrome.storage.session` is held in memory by Chrome and is cleared when the browser session ends. UX HeatGrid does not use `storage.local`, `storage.sync` or cookies. The only thing kept between browser sessions is the side-panel theme choice, which contains no page or interaction data; recordings are never saved between browser sessions.

## Network and external services

UX HeatGrid does not use cookies, remote code, artificial intelligence services or any other external service. Chrome itself may handle installation and updates under Google's policies.

## Sharing

UX HeatGrid does not transmit, sell or share any data. The developer never receives it.

UX HeatGrid's use of information received through Chrome APIs adheres to the [Chrome Web Store User Data Policy](https://developer.chrome.com/docs/webstore/program-policies/user-data-faq), including the Limited Use requirements. Data is used only to provide the page-inspection and recording features described here.

## Permissions

| Permission | Purpose |
| --- | --- |
| `activeTab` | Temporary access to the current tab after you click the UX HeatGrid toolbar icon. |
| `scripting` | Inject the UX HeatGrid runtime into that tab on demand. |
| `sidePanel` | Display the Overview · Predict · Record side panel. |
| `storage` | Session-only storage used to continue a recording across page navigations. |

UX HeatGrid requests no host permissions and is not injected into pages automatically. Chrome blocks extensions on its own pages, the Chrome Web Store and other restricted pages.

## Your control

- Predict and Record start only when you choose **Start**.
- Stop a recording at any time; **Clear recording** and **Reset prediction** remove results immediately.
- Closing the tab removes all of UX HeatGrid's data for that tab.
- Uninstalling UX HeatGrid removes the extension and its storage.
