Privacy Policy

How we collect, use, and protect your information

Last Updated: July 12, 2026

Introduction

Welcome to YouTool.io ("we," "our," or "us"). YouTool.io is a creator-supported set of YouTube tools maintained by an independent developer. The public website tools and Chrome extension tools are offered without a required subscription at the time this Privacy Policy was last updated. The service does not currently run display advertising, sell ad inventory, or add watermarks to downloads or exports. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you visit our website, use our YouTube analytics tools, sign in to your account, connect a YouTube channel, or use the YouTool.io Chrome extension.

Information We Collect

Information You Provide Directly

  • YouTube URLs and IDs: When you use our tools, you provide YouTube video URLs, channel URLs, or IDs for analysis
  • Search Queries: Keywords and search terms you enter into our tools
  • Tool Usage Data: Information about which tools you use and how you interact with them
  • Contact Information: Name, email address, topic, and message content you submit through our contact form

Information Collected Automatically

  • Device Information: Browser type, operating system, screen resolution, and device identifiers
  • Usage Analytics: Pages visited, time spent on site, click patterns, and feature usage
  • Technical Data: IP address, user agent, referral URLs, and session information
  • Cookies and Local Storage: Preferences, session data, and analytics information

Account, Extension, and Connected Channel Information

  • Account Profile: If you sign in with Google, we receive basic profile information such as your name, email address, avatar, and Google account identifier through Supabase authentication
  • Extension Session Data: When you link the Chrome extension to your YouTool.io account, we create extension session records, token hashes, expiration dates, revocation status, user agent, and last-used timestamps
  • Connected YouTube Channel: If you choose to connect your YouTube channel, we store your channel ID, channel title, thumbnail URL, authorized scopes, token expiration time, and OAuth tokens needed to refresh your connection
  • Connected Channel Analytics History: While your YouTube channel remains connected, we may store read-only YouTube Data API and YouTube Analytics API results such as channel snapshots, video metadata, daily performance metrics, traffic source breakdowns, audience/device/geography breakdowns, playlist add/remove metrics, comment counts, and generated insight reports so your account can compare performance over time. We may also review connected-channel patterns internally to improve tools and develop aggregate benchmark or experiment features. We do not publish individual channel analytics, public case studies, or creator-specific examples without permission
  • Extension Settings: The extension stores enabled features, theme choices, selected stats range, and daily stats cache locally in Chrome storage on your device

Google OAuth Scopes

YouTool.io requests Google access only for the feature you choose to use.

  • openid, email, profile: Used for Google sign-in so Supabase can create and maintain your YouTool.io account session
  • https://www.googleapis.com/auth/youtube.readonly: Used only when you connect a YouTube channel, so YouTool.io can read channel and video metadata needed for connected-channel tools
  • https://www.googleapis.com/auth/yt-analytics.readonly: Used only when you connect a YouTube channel, so YouTool.io can read YouTube Analytics reports for your own connected channel

Third-Party Data

  • YouTube API Data: Public information retrieved from YouTube's API including video metadata, channel statistics, playlist data, thumbnails, tags, descriptions, comment counts, and publicly visible comments when a tool specifically requests comments
  • YouTube Analytics Data: If you connect your own channel, we use your authorization to retrieve and store read-only channel analytics such as views, impressions, thumbnail click-through rate, watch time, average view duration, average percentage viewed, subscriber gains/losses, engagement metrics, traffic sources, audience/device/geography breakdowns, and content type breakdowns
  • YouTube Page Content: The extension may read the current YouTube page URL, video ID, channel ID, title, transcript, description, tags, thumbnail, or visible page signals when you enable or use related features
  • Analytics Services: Data from Google Analytics, Vercel Analytics, and other measurement tools

Data Sharing and Disclosure

We do not sell, trade, or rent your personal information to third parties. We also do not sell Google API data, use it for advertising, or use it for personalized advertising. We may share information in the following limited circumstances:

Service Providers

  • Supabase: We use Supabase for authentication, account profiles, extension session records, and connected YouTube channel connection records
  • Google OAuth and YouTube APIs: We use Google sign-in, YouTube Data API, and YouTube Analytics API to authenticate users and provide requested creator tools
  • Analytics Providers: Google Analytics, Vercel Analytics for usage statistics
  • Hosting Services: Vercel for website hosting and performance
  • Return YouTube Dislike: If you enable dislike estimates, the extension requests dislike data for the current YouTube video from Return YouTube Dislike

Legal Requirements

We may disclose information if required by law, court order, or government request, or to protect our rights, property, or safety.

Data Retention

  • Search History: Stored locally in your browser and can be cleared at any time
  • Account Profile: Stored while your YouTool.io account remains active or until deletion is requested
  • Extension Sessions: Stored while the extension is linked to your account and may be revoked when you sign out or disconnect the extension
  • YouTube Connection Records: Stored while your channel remains connected. Disconnecting your channel marks the connection as disconnected, clears stored OAuth tokens where supported by the connection record, and stops use of the connection for new requests
  • Connected Channel Analytics History: Stored while your channel remains connected so we can power historical comparisons, outlier detection, topic/metadata pattern analysis, and full channel analysis. Connected-channel history is focused on metrics and metadata; YouTool.io does not store comment text as part of connected-channel private analytics history. Disconnecting your channel disables analytics history and deletes stored private connected-channel analytics history tied to your account
  • Extension Stats Cache: Stored locally in Chrome storage once per day for the selected 1D, 7D, or 30D range so the popup can load quickly
  • Analytics Data: Aggregated usage data retained for service improvement
  • Tool Results: Public website tool results are generally retrieved and returned in real time. Connected-channel account analytics may be stored as analytics history while your YouTube channel remains connected
  • Session Data: Cleared when you close your browser or end your session

Your Rights and Choices

Access and Control

  • Clear your local search history through browser settings
  • Disable cookies through your browser preferences

  • Sign out of or uninstall the Chrome extension to stop extension-side collection

Security Measures

We implement appropriate technical and organizational security measures to protect your information, including:

  • HTTPS encryption for all data transmission
  • Secure hosting infrastructure with Vercel
  • Regular security updates and monitoring
  • Limited data collection and retention practices
  • No collection of YouTube passwords
  • Restricted access to authentication and YouTube connection records used to provide account and extension features
