1 Overview
3D Audio Visualizer Pro ("the Extension") is a Chrome browser extension that renders real-time 3D audio visualizations on web pages, including YouTube. This Privacy Policy explains what information is (and is not) collected when you use the Extension.
2 Data We Do Not Collect
The Extension does not collect, store, transmit, or share any of the following:
- Personal identification information (name, email address, etc.)
- Browsing history or URLs visited
- Audio content or media data from pages you visit
- Device information or hardware identifiers
- Location data
- Usage analytics or crash reports
- Cookies or local storage data beyond what the browser itself manages
3 Why Certain Permissions Are Requested
The Extension may request the following browser permissions, used solely for the stated purposes:
- activeTab / scripting — Injects the visualizer canvas into the current browser tab so the visualization can be displayed on screen.
- storage — Saves your visual preferences (e.g., theme, color settings) locally in Chrome's built-in storage. This data never leaves your device.
4 Payments & Billing (ExtensionPay / Stripe)
3D Audio Visualizer Pro offers an optional paid upgrade ("Pro" tier) processed through ExtensionPay, a third-party payment service for Chrome extensions. ExtensionPay uses Stripe as its underlying payment processor.
When you subscribe to the Pro tier:
- You are redirected to a secure Stripe-hosted payment page managed by ExtensionPay.
- Your payment details are transmitted directly to Stripe — never to our servers.
- ExtensionPay returns only a boolean "paid / not paid" status to the Extension in order to unlock Pro features. No financial data is shared with us.
- Stripe may collect and process data as described in their own Privacy Policy.
