YouTube Perfect Subtitles Privacy Policy

Introduction

We value your privacy and are committed to protecting any data that might be handled by our YouTube Better Subtitles extension. This policy explains our practices regarding data collection, usage, and protection in a clear and transparent manner.

Information We Process (Not Collect Locally)

When using the extension, we process:

• YouTube video transcripts from videos you choose to translate.
• Your selected target language preference.
• Subtitle positioning, font size, transparency, and delay preferences.
• Video-specific subtitle delay settings for synchronization.

Important Note: Display preferences (font size, position, transparency, delay) are stored locally in your browser using Chrome’s storage API. We do not have access to these settings. Transcripts are sent to our secure server for AI translation processing and are not permanently stored—they are only retained temporarily during processing and immediately deleted afterward.

Information We Collect on Our Servers

To provide the translation service, we collect and store:

• Account Information: Email address, name, and profile picture from Google OAuth (used for authentication only).
• Subscription Data: Your selected plan (Free, Basic, Pro), payment status, and token usage tracked through Stripe.
• Usage Metrics: Number of tokens consumed, video IDs processed, processing timestamps, and AI model costs (for billing accuracy and service improvement).
• Session Data: Secure session tokens to maintain your login state (automatically expire after 30 days).

What We Don’t Collect:

• We do not track which specific videos you watch.
• We do not store video transcripts or translated subtitles permanently.
• We do not collect browsing history or viewing habits.
• We do not access your YouTube account data beyond publicly available transcripts.
•  

How We Use the Information

The collected information is used solely for:

• Authentication: Verifying your identity through Google OAuth.
• Translation Processing: Sending transcripts to AI services (OpenRouter/Anthropic) for translation.
• Billing Management: Tracking token usage to enforce plan limits and calculate costs.
• Service Improvement: Analyzing processing times and costs to optimize performance.
• Customer Support: Troubleshooting issues and responding to user inquiries.

We never use your data for advertising, marketing to third parties, or any purpose unrelated to providing the subtitle translation service.

Permissions We Request and Their Usage

The extension requests the following permissions to function correctly:

• storage: To save your display preferences (font size, position, transparency, delay) locally on your device.
• activeTab: To access the YouTube page content and video player for subtitle injection.
• tabs: To communicate between the extension popup and YouTube pages for real-time settings updates.
• host_permissions:
  • https://www.youtube.com/*: To read video transcripts, detect video playback, and inject subtitle overlays.
  • https://codingdir.com/*: To communicate with our authentication and translation API servers.

Data Protection

We implement several measures to protect your privacy and security:

• Secure Authentication: Google OAuth 2.0 with industry-standard token-based sessions.
• Encrypted Communication: All data transmitted between the extension and our servers uses HTTPS encryption.
• Payment Security: All payment processing handled by Stripe (PCI DSS compliant)—we never see or store your credit card information.
• Server-Side Validation: All plan verification and token limits enforced on our servers to prevent client-side manipulation.
• Session Expiration: Login sessions automatically expire after 30 days of inactivity.
• Minimal Data Retention: Transcripts are deleted immediately after translation; only usage statistics are retained.
• No Third-Party Tracking: We do not use analytics tools, tracking pixels, or advertising networks.

Information Sharing

We do not:

• Sell or rent your personal information to anyone.
• Share your data with third parties for marketing purposes.
• Use your data for advertising or profiling.
• Share video viewing habits or translation history with anyone.

Third-Party Services We Use:

1. Google OAuth: For secure authentication. Google’s use of your login data is governed by their privacy policy. We only receive your email, name, and profile picture.
2. Stripe: For payment processing and subscription management. Stripe collects payment information, billing address, and email. We do not have access to your full credit card details. Their use of your data is governed by Stripe’s privacy policy.

Data Processed by AI Services:

• Video transcripts (text only, no video content)
• Source and target language preferences
• No personally identifiable information is sent to AI services

Server Usage

Our extension uses a secure backend server (codingdir.com) for:

• User authentication and session management
• Subscription plan verification and token tracking
• AI translation API requests and response handling
• Payment webhook processing from Stripe

All server operations use encrypted HTTPS connections. User data is stored in a secure MySQL database with access restricted to authorized administrators only.
