PrivacyPolicy.
Last updated: March 15, 2026
1. Overview
StylixAI is a Chrome extension that helps users customize any website using AI-powered natural language commands. We are committed to protecting your privacy and being transparent about our data practices.
Key Point: StylixAI does NOT collect, store, or sell any personal data. All AI processing happens locally in your browser. The only external call is license key verification via Lemon Squeezy's official API for Pro subscription management.
2. Data Collection
StylixAI does not collect any of the following:
- Personal information (name, email, phone number)
- Browsing history or analytics
- Website credentials or account data
- Cookies or tracking identifiers
- Usage statistics or telemetry
3. Data Processing
The extension processes the following data locally in your browser only:
- Page DOM elements: The CSS and structure of elements you select are read from the page DOM to generate AI-powered modifications. This content is sent to your chosen AI provider (Gemini, ChatGPT, Claude, or Grok) via your own logged-in session.
- User settings: Your preferences (AI provider, style presets, saved rules, theme) are stored locally using Chrome's
chrome.storage.localandchrome.storage.syncAPIs. - License key: If you activate a Pro subscription, your license key is sent to Lemon Squeezy's official API for verification. No personal data is included in this request.
4. Third-Party AI Services
When you use StylixAI, element data is sent to your chosen AI provider through their web interface embedded in the extension's side panel. These services have their own privacy policies:
- OpenAI (ChatGPT) Privacy Policy
- Google (Gemini) Privacy Policy
- Anthropic (Claude) Privacy Policy
- X.AI (Grok) Privacy Policy
Important: StylixAI does NOT operate its own servers. AI requests go directly from your browser to your chosen AI provider's website. The only external API call we make is to Lemon Squeezy for license verification.
5. Subscription & License Verification
StylixAI offers a Pro subscription activated via a license key purchased from Lemon Squeezy. When you enter a license key, the following data is sent to Lemon Squeezy's official API (api.lemonsqueezy.com):
- Your license key
- The product ID (to identify StylixAI)
No personal information (name, email, payment details) is sent by the extension. Lemon Squeezy returns only the license validity status and purchase date. This verification happens once daily for active Pro users.
6. Data Storage
All data is stored locally on your device:
- User settings are stored via
chrome.storage.local - Subscription status syncs via
chrome.storage.syncfor subscription integrity - No data is stored on external servers
- No databases or cloud storage is used
- Uninstalling the extension removes all stored data
7. Chrome Permissions Justification
StylixAI requests the following browser permissions:
Used to render the StylixAI control center beside your current page, allowing you to manage AI settings, apply styles, and generate modifications without leaving the page.
Required to inject the StylixAI element selector onto any webpage and to extract element CSS/structure from the page DOM when you select elements.
Both chrome.storage.local and chrome.storage.sync are used to persist your style presets, saved rules, AI provider preferences, and subscription status across sessions.
Required for the background Service Worker to manage AI provider tabs (Gemini uses managed tabs) and to relay element data via secure chrome.runtime.sendMessage protocols.
Routing headers are modified exclusively to bypass restrictive X-Frame-Options and Content-Security-Policy blocks, enabling the secure loading of AI provider websites inside the extension's embedded iframes.
Host Permissions
The extension requires access to these specific domains:
<all_urls>— To inject the element selector and apply CSS modifications on any webpagechatgpt.com / chat.openai.com— To load ChatGPT in the embedded AI Chat panelgemini.google.com— To load Gemini in the embedded AI Chat panelgrok.com— To load Grok in the embedded AI Chat panelclaude.ai— To load Claude in the embedded AI Chat panelapi.lemonsqueezy.com— To verify Pro license keys
8. Data Sharing
StylixAI does NOT:
- Sell user data to any third party
- Share data with advertisers
- Use data for profiling or targeting
- Transfer data to data brokers or information resellers
- Use data for creditworthiness or lending purposes
- Use data for personalized advertising
9. Data Retention
- User settings (presets, rules, provider preferences) are stored locally until you uninstall the extension or manually reset them.
- Subscription status is stored in
chrome.storage.syncfor subscription integrity; it persists across reinstalls but contains no personal information. - Page element data is processed in memory only during active modification and is never written to disk or transmitted to our servers.
- Uninstalling the extension permanently removes all locally stored data.
10. User Rights & Data Control
You have full control over your data at all times:
- Review: All stored settings can be viewed directly in the extension's Settings tab.
- Delete: You can reset all settings to defaults or uninstall the extension to remove all data.
- Opt out: You can disable any feature individually via toggle switches in Settings.
- Portability: Since no data is stored on external servers, there is no remote data to export or transfer.
11. Security
- All communication with AI providers happens over HTTPS encrypted connections.
- License key verification with Lemon Squeezy uses HTTPS POST requests.
- No data is transmitted over unencrypted channels.
- The extension requests only the minimum permissions necessary for its core functionality.
- Content Security Policy (CSP) is enforced on extension pages to prevent code injection.
12. Children's Privacy
StylixAI is not intended for use by children under 13. We do not knowingly collect data from children.
13. Changes to This Policy
