Welcome to TubeVocab ("we," "our," or "us"). We are committed to protecting your privacy and personal information. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our website and services at tubevocab.com (the "Service").

User Preferences: Your language preferences, learning settings, and customization options.
Learning Data: Vocabulary cards you create, words you save, learning progress, and review history.

Device Information: Browser type, operating system, device type, and screen resolution.
Log Data: IP address, access times, pages viewed, and referring URLs.

Cookies and Similar Technologies: We use cookies to maintain sessions, remember preferences, and analyze usage patterns.

2.3 Authentication

We use Google OAuth solely for user authentication. When you sign in with Google, we only receive your basic profile information (name and email address) to create your account. We do not access your Google Drive, Gmail, Google Calendar, or any other private Google services. We do not request any sensitive OAuth scopes beyond basic profile information.

2.4 Third-Party Services

YouTube: When you use TubeVocab to learn from YouTube videos, we interact with YouTube's API to fetch video information and subtitles. Your use of YouTube content is also subject to YouTube's Terms of Service and Google's Privacy Policy.
Google Analytics: We use Google Analytics to understand how users interact with our Service.
Microsoft Clarity: We use Microsoft Clarity for session recordings and heatmaps to improve user experience.
VibeLoft: We use VibeLoft product telemetry to measure aggregate daily visits and display trusted usage statistics in the VibeLoft community. VibeLoft receives the page path without query parameters or fragments, event time, request IP address, a random local device identifier, and a hash of coarse device characteristics. We do not send your TubeVocab account, vocabulary, subtitle, or learning data to VibeLoft.

These analytics and product telemetry tools are used only to understand aggregate usage patterns. We do not use them to track individual users across websites or services, and we do not combine analytics data with your personal account information.
