OKU Link Extension

Privacy Policy

Last updated: January 2026

Overview

The OKU Link browser extension ("the Extension") is designed to automatically track your anime watching progress across supported streaming sites. This privacy policy explains what data we collect, how we use it, and your rights regarding that data.

Data We Collect

The Extension collects the following information:

  • Anime viewing data: The title of the anime you're watching, episode numbers, and watch progress on supported streaming sites
  • Authentication token: Your Otakiroku login token, stored locally to sync your progress with your account
  • Site preferences: Your configured streaming sites and their selectors
  • Watch history: Recent anime you've tracked, stored locally for the extension popup

How We Use Your Data

  • Progress tracking: We send your watch progress to Otakiroku servers to update your anime list
  • Authentication: Your token is used to authenticate API requests to your Otakiroku account
  • Local storage: Recent activity and preferences are stored locally in your browser for quick access

Data Storage

  • Local storage: Preferences, recent history, and authentication tokens are stored in Chrome's local and sync storage
  • Server storage: Only your anime progress (title, episode, score, status) is sent to Otakiroku servers
  • No third parties: We do not share your data with any third-party services

Permissions Explained

The Extension requires the following browser permissions:

  • activeTab: To inject the visual selector tool when you click "Add This Site"
  • storage: To save your preferences and authentication locally
  • tabs: To detect which streaming site you're on and read the page title
  • scripting: To extract anime title and episode information from streaming sites
  • cookies: To read authentication cookies from otakiroku.com for seamless login
  • host_permissions (all URLs): To work on any streaming site you configure, not just preset ones

Your Control

  • Clear data: You can clear your local watch history from the extension
  • Remove sites: You can remove any custom streaming sites you've added
  • Uninstall: Removing the extension deletes all locally stored data
  • Account deletion: Deleting your Otakiroku account removes all server-side data

Data Security

We take reasonable measures to protect your data:

  • Authentication tokens are stored securely in Chrome's protected storage
  • We do not log or store your browsing history beyond anime-related activity

Changes to This Policy

We may update this privacy policy from time to time. We will notify users of any significant changes through the extension or website. Continued use of the Extension after changes constitutes acceptance of the updated policy.
