Privacy Policy for vPrompter

Last updated: August 16, 2025

Introduction

vPrompter ("we", "our", "us") respects your privacy. This policy explains what data we collect, how we use it, and your choices regarding our Chrome extension for AI video prompt management.

Information We Collect

• Google account basic profile and email – Collected when you sign in using Google OAuth for account authentication.
• Prompt data – Video prompts you create, modify, or save within the extension are stored locally in your browser.
• Usage statistics – Local counts used to manage free tier limits (3 AI modifications per day). Aggregated usage data may be sent to our backend to verify subscription status.
• Subscription information – Payment status and subscription details managed through ExtPay for premium features.

What We Don't Collect

• API Keys – We do not require or store your OpenAI API keys. All AI processing is handled through our secure backend service.
• Video Content – We only process text prompts, never your actual video files or content.
• Browsing Data – We do not access your browsing history or other websites you visit.

How We Use Your Information

• To authenticate you and enable account-based features.
• To provide AI-powered prompt modification services through our secure backend.
• To enforce subscription limits and manage premium features access.
• To improve the functionality and user experience of the extension.
• To provide customer support when requested.

What We Don't Do

• We do not sell, rent, or trade your personal information to third parties.
• We do not use your data for advertising or marketing purposes.
• We do not access your browsing history or other Chrome browser data.
• We do not store or analyze your video content - only the text prompts you create.

Data Storage and Security

Most data is stored locally on your device using Chrome's secure storage APIs. Minimal data (email, subscription status) is stored securely on our backend servers with industry-standard encryption and security measures. We manage all AI API credentials on our backend, so you don't need to provide or manage any API keys.

Third-Party Services

• Google OAuth – Used for secure sign-in authentication.
• ExtPay – Used for optional premium subscription management.
• OpenAI GPT-4 – AI prompt modification requests are processed through our secure backend proxy to protect your API credentials.

Your Rights and Choices

• You may revoke Google sign-in access at any time from your Google account settings.
• You may delete local extension data by removing the extension from your browser.
• You may request deletion of your account data by contacting us.
• You may use the extension without signing in (with limited features).

Data Retention

Local data is retained until you remove the extension or clear your browser data. Backend account data is retained while your account is active and for a reasonable period after account deletion for security and legal compliance.

Updates to This Policy

We may update this Privacy Policy from time to time. We will notify users of significant changes through the extension or by posting the updated policy on our website.
