Privacy Policy

Last updated: March 28, 2026

At SageTube ("we", "us", "our"), we respect your privacy and are committed to protecting your personal data. This Privacy Policy explains how we collect, use, and safeguard your information when you use our website at sagetube.ai, our Chrome browser extension, and related services (collectively, the "Service"). This policy is in accordance with the General Data Protection Regulation (GDPR) and other applicable data protection laws.

1. Information We Collect

We collect and process the following categories of personal data:

  • Account Information: Name and email address when you register for an account.
  • Usage Data: IP address, browser type, device information, pages visited, and interaction patterns with the Service.
  • Payment Information: Billing details and transaction history, processed securely through our payment provider Stripe. We do not store your full credit card details on our servers.
  • User Content: YouTube video URLs, PDF documents, and other content you submit to the Service for processing and analysis.
  • AI Interaction Data: Chat queries, conversations with AI Experts, and search queries you make within the Service.
  • Chrome Extension Data: When you use the SageTube Chrome extension, it collects YouTube video metadata (titles, descriptions, URLs) from pages you interact with. The extension only activates on YouTube pages and only transmits data when you explicitly use its features.
  • Mobile Application Data: When you use the SageTube mobile app, we collect device information (device model, OS version), authentication tokens, and Firebase Cloud Messaging (FCM) device tokens for push notification delivery. FCM tokens are hashed and stored securely. Stale tokens are automatically pruned when they become invalid.
  • Guest Trial Data: If you use the Service without creating an account (Guest Trial), we may collect limited technical data such as your IP address, browser information, and session-level interaction data. This data is ephemeral and is not linked to a persistent identity.
  • Pulse Subscriber Data: If you subscribe to receive Live Knowledge Pulse email notifications for a public Expert, we collect your email address and a unique subscriber token. This data is used solely for delivering digest notifications and is retained until you unsubscribe or the subscription is pruned after a period of inactivity.
  • Creator Monetization Data: If you enable Creator Monetization, Stripe collects and processes your identity verification, bank account, and payout information as part of the Stripe Connect onboarding. SageTube stores your Stripe Connect account ID and transaction records but does not store your banking details.

2. How We Use Your Information

Your personal data is used for the following purposes:

  • Service Provision: To operate the Service, including processing your content through AI models, generating transcriptions, creating vector embeddings for search, and enabling conversations with AI Experts.
  • Account Management: To manage your account, subscriptions, wallet balance, and usage tracking.
  • Communication: To respond to support requests, send service notifications, and provide important updates about your account or the Service.
  • Analytics and Improvement: To understand how users interact with the Service and to improve its functionality and performance.
  • Legal Compliance: To comply with legal obligations, enforce our terms of service, or protect our legal rights.
  • Marketing: With your consent, to send promotional content that may interest you. You can opt out at any time.

3. AI Processing and Automated Decision-Making

SageTube uses artificial intelligence to provide its core features. This involves:

  • Content Processing: Your submitted content (YouTube videos, PDFs) is processed by AI models to generate transcriptions, summaries, and vector embeddings that enable semantic search and AI-powered conversations.
  • AI Chat Responses: When you interact with AI Experts, your queries are processed by third-party AI models to generate responses. These responses are generated automatically but do not constitute legally or similarly significant decisions about you.
  • Embeddings and Vector Storage: Your content is converted into numerical vector representations and stored in a vector database to enable intelligent search and retrieval.

You have the right to request human review of any AI-generated output and to understand the logic involved in automated processing of your data.

4. Legal Basis for Processing

We process personal data based on the following legal grounds:

  • Performance of Contract (Article 6(1)(b) GDPR): Processing necessary to provide the Service you have subscribed to, including AI content analysis, transcription, and chat functionality.
  • Consent (Article 6(1)(a) GDPR): For marketing communications and analytics cookies. You may withdraw consent at any time.
  • Legal Obligation (Article 6(1)(c) GDPR): To comply with applicable laws, such as tax and accounting requirements.
  • Legitimate Interests (Article 6(1)(f) GDPR): For service improvement, fraud prevention, and security. We balance these interests against your rights and freedoms.
