Privacy Policy

Last updated: June 10, 2026

This policy describes how YouTube Subtitle Classifier (“we”, “the extension”, “the service”) collects, uses, and protects information when you use our Chrome extension, website, and backend API.

What we collect

• Google account info — When you sign in, we receive your name, email, and profile picture via Google / Firebase Authentication.
• YouTube transcript data — Caption text from videos you choose to process is sent to our API to generate AI outputs.
• Usage data — Generation counts, premium status, and cached task metadata are stored in Firebase Realtime Database under your user ID.
• Payment info — Payments are handled by Stripe. We do not store full card numbers. We may store Stripe customer and subscription IDs linked to your account.

How we use data

• Authenticate you across the extension and website
• Generate and cache AI content from transcripts you submit
• Enforce free-tier limits and activate Premium subscriptions
• Provide support when you contact us

Third-party services

• Google / Firebase — Authentication and user profile storage
• AWS Lambda — API processing and webhook handling
• OpenAI — AI text generation from submitted transcripts
• Stripe — Subscription billing and payment processing

Data retention

Generated tasks and transcript payloads are stored under your Firebase user path while you use the service. You may request deletion by emailing info@34apps.com.

Security

Premium status and generation limits are set only by our backend (Firebase Admin SDK). Client apps cannot modify billing or quota fields directly.

Children

The service is not directed at children under 13. We do not knowingly collect their data.

Changes

We may update this policy. The “Last updated” date above will change when we do. Continued use of the service means you accept the revised policy.
