C. Live2D Web Canvas Browser Extension — Privacy Policy

Applies to: Chrome / Edge browser extension Live2D Web Canvas (including the BETA build).
Effective date: 2025-01-01  |  Last updated: 2026-05-14
Publisher: Beijing Tianxiansheng Software Technology Center

This section describes how the Chrome / Edge browser extension Live2D Web Canvas (the "Extension") handles user data. It does not apply to other services on this website, our WordPress plugin or any other client products.

C1. Data we collect

Mapped to the Chrome Web Store data-usage categories, the Extension processes only the following two types of data, and only after the user has explicitly signed in:

Category What it is When it is collected
Authentication information An access token (JWT containing key and sign) issued by our website, used to unlock paid features. Only after the user clicks "Sign in" inside the Extension and completes the login flow on www.live2dweb.com.
Personally identifiable information An internal account identifier bound to the user account. The Extension does not collect names, email addresses, phone numbers, ages, government IDs or postal addresses. Same as above; obtained together with the access token after sign-in.

What we explicitly do NOT collect

  • We do not read, store or upload the URLs, titles or browsing history of pages you visit.
  • We do not read or upload any text, images, form input, cookies or DOM nodes from the host page.
  • We do not collect mouse clicks, scroll position or keystrokes (the character only animates locally based on the live cursor position; nothing leaves your browser).
  • We do not collect geolocation, IP address or device fingerprints.
  • We do not collect health, medical, financial, credit or payment-card information.
  • We do not collect emails, instant messages or any form of personal communication.

C2. Where data is stored

Location Contents
chrome.storage.sync (local + synced via Chrome account) Extension preferences: enabled flag, selected model, selected texture, tip-bubble frequency, toolbar toggles.
chrome.storage.local (local only) The access token (JWT) obtained after sign-in. Never synced across devices.
Browser IndexedDB (local) Live2D model files the user has explicitly downloaded from the model library, kept for offline use and faster loading.
Our backend at https://api.live2dweb.com The user account itself (created when the user originally signed up on our website, independent of the Extension); plus standard server access logs (timestamp, request path, response code) for requests carrying the token. Server logs do not contain page contents.

C3. How the data is used (single purpose)

The Extension's single purpose is to render a Live2D character overlay in the bottom-right corner of webpages. The data above is used only to:

  1. identify paid users so that paid features (e.g. the "Custom model URL" mode) can be unlocked;
  2. download user-selected model files from our own domain https://download.live2dweb.com;
  3. persist user preferences across tabs and devices.

C4. Sharing and transfer

  • We do not sell user data.
  • We do not transfer user data to any third party for purposes unrelated to the Extension's single purpose.
  • We do not use or transfer user data to determine creditworthiness or for lending purposes.
  • Apart from our own domains (www.live2dweb.com, api.live2dweb.com, download.live2dweb.com), the Extension does not contact any third-party server.

C5. Your control over your data

  • Sign out: In the Extension options page (click the toolbar icon → Options → Login tab) click "Sign out" to clear the locally stored access token.
  • Clear cached models: In the "V1 Model Library" tab you can delete each downloaded model individually, freeing IndexedDB storage.
  • Wipe everything: Uninstalling the Extension via chrome://extensions removes all data the Extension keeps in chrome.storage and IndexedDB.
  • Account deletion / server-side data removal: Send a deletion request to the contact email below. We will process it within a reasonable time.

C6. Data security

  • The access token is transmitted over HTTPS and protected by HMAC signing to prevent tampering.
  • The token is stored only in chrome.storage.local on your device and never appears in URLs or logs.
  • The Extension does not use any remotely hosted code: all JavaScript ships inside the extension package; assets fetched from download.live2dweb.com are model data only (binary / images / JSON) and are never executed as code.

C7. Children's privacy

The Extension is not directed at children under 13 and does not knowingly collect any personal information from children.

C8. Changes to this policy

For material changes we will update the "Last updated" date above and announce them in the Extension's update notes. Continued use of the Extension constitutes acceptance of the revised policy.
