Privacy Policy

ToonKit is a Chrome browser extension that helps you download, normalize, and export comic pages from public or owned content. This Privacy Policy explains what data ToonKit handles, where it is stored, and how each of the extension's browser permissions is used.

1. Data We Collect

ToonKit does not collect any personal information. The extension does not require an account, does not track usage, and does not send crash reports, analytics, or behavioral data to any server.

2. Data Stored Locally

ToonKit stores all working data inside your browser, on your own device. This data never leaves your computer unless you explicitly export it (for example, as a ZIP or CBZ file you save through your browser's download manager).

IndexedDB (toonkit database)

• Jobs — metadata about each download job (source URL, status, title)
• Blobs — raw image data extracted from source pages
• Thumbnails — small preview images for the in-app grid
• Processed cache — pipeline results so re-runs are instant
• Presets — your saved pipeline configurations
• Adapter manifest cache — list of built-in site extractors

Extension storage (chrome.storage)

User interface preferences such as language (Turkish / English) and theme (light / dark).

You can clear all of this data at any time by removing the extension (chrome://extensions→ ToonKit → Remove) or by clearing site data through your browser's developer tools.

3. Permissions, Explained

ToonKit requests the following Chrome permissions. Each is used only for the purpose stated below.

• Host permission (<all_urls>) — required so you can extract pages from any webcomic site you choose to visit. ToonKit does not run on a page until you explicitly trigger an extraction. No passive content script is injected into the sites you browse.
• scripting — injects the extraction script into the source tab on demand, only when you start a job.
• tabs — opens the ToonKit application tab and locates the source tab you want to extract from.
• downloads— saves exported files (ZIP, CBZ, image sequence) to your computer through Chrome's download manager.
• storage — saves your interface preferences.
• alarms — runs the auto-pipeline scheduler that processes queued jobs in the background.
• declarativeNetRequestWithHostAccess — adds a Referer header to image fetches when a source site requires it for hotlink protection. The rule is dynamic and active only while ToonKit is fetching.
• notifications — shows a system notification when a long-running export finishes.

4. Network Requests Made by ToonKit

The extension makes only two kinds of outbound requests:

a. Source images you ask to extract

When you start a download, ToonKit fetches the page's images directly from the source website. These requests go from your browser to that site — they do not pass through any ToonKit or WebtoonLib server.

b. Adapter manifest updates

ToonKit periodically fetches a signed list of supported sites from https://img.webtoonlib.to/toonkit/adapters/manifest.json. The manifest is cryptographically verified with an Ed25519 signature before being applied. Only the standard HTTP request metadata visible on any web request (your IP address and browser User-Agent) is observable on this endpoint. No ToonKit-specific data, no usage data, and no personal data are included in these requests.

5. Data We Do Not Send

• No telemetry or usage analytics
• No crash reports
• No A/B testing or experimentation framework
• No advertising or tracking pixels
• No user identifier of any kind
• No copies of extracted images sent to any server we operate

6. Third Parties

ToonKit does not integrate with any third-party analytics, advertising, or data-collection services. The only external endpoint contacted by the extension itself is the adapter manifest hosted on our own CDN (img.webtoonlib.to).

7. Children's Privacy

ToonKit is not directed at children under 13 and does not knowingly collect any data from any user, including minors.

8. Legal Use

ToonKit is a personal workflow tool intended for content you own, have licensed, or that is in the public domain. The extension does not bypass DRM protection. You are responsible for complying with the terms of service of source websites and with applicable copyright law in your jurisdiction.

9. Changes to This Policy

We may update this policy when ToonKit changes (for example, when a new permission is added or removed). The “Last updated” date at the top of this page reflects the most recent revision. Material changes will also be mentioned in the extension's release notes.
