# Privacy Policy for UI Tweaker

**Last updated:** July 19, 2026

UI Tweaker (“the Extension”) is a Chrome extension that restyles websites in your browser. This policy explains what data is handled and how.

## Single purpose

UI Tweaker changes how websites look on your device (themes, hide/clutter tools, layout presets, custom CSS, and optional AI redesign). It does not provide unrelated services such as advertising networks or credit scoring.

## Data we handle

### Stored on your device only
The Extension may save in Chrome local storage (`chrome.storage.local`):

- Per-site UI settings (themes, presets, hidden element selectors, custom CSS, tuning options, AI redesign CSS/prompt)
- Optional AI API settings you enter (API key, base URL, model)

This data stays on your computer unless you export it yourself. The developer does **not** receive a copy of this storage by default.

### Website content (on your device)
To fulfill its purpose, the Extension may read and modify page content in your browser (DOM structure, text, styles) so it can apply themes, hide elements, and restyle the page.

### Optional AI redesign
If you use AI redesign with your own API key:

- The Extension may send limited page context (such as page URL/host, title, headings, and a short structure outline) plus your written prompt to the AI provider **you** configure (for example OpenAI or another OpenAI-compatible API).
- That request is made from your browser using your key. The Extension developer does not operate that API or receive your key.

If you use **Free demo** mode, no API call is made; redesign CSS is generated locally.

## Data we do not collect

We do not intentionally collect or sell:

- Name, email, or other contact details
- Health or financial information
- Passwords for your websites
- Full browsing history
- Location / GPS
- Personal communications

## Sharing and selling

- We do **not** sell user data.
- We do **not** transfer user data to third parties for advertising or unrelated analytics.
- The only third-party transfer that may occur is optional, user-initiated AI API requests to the provider you choose, solely to generate redesign CSS.

## Permissions (why they exist)

- **storage** — save your tweaks and optional API settings locally  
- **activeTab** — work with the tab you open the Extension on  
- **scripting** — inject styles/scripts needed to restyle the page  
- **Host access** — apply tweaks on websites you choose to modify  

## Your choices

- Clear site tweaks with **Reset this site** in the Extension  
- Clear Extension data in Chrome settings, or uninstall the Extension  
- Do not enter an API key if you do not want optional AI requests  

## Children’s privacy

The Extension is not directed at children under 13. Do not use it with personal data of children if that would violate applicable law.

## Changes

We may update this policy when the Extension changes. The “Last updated” date will be revised accordingly.
