About this extension

"Irodori Downloader for pixiv" (hereinafter "the Extension") is a Chrome extension for downloading works from pixiv.net.

Data Collection

The Extension does not transmit or collect any of your data to external servers. It does not perform any access analytics or usage statistics tracking.

Local Storage

The Extension stores the following data only within your browser:

• Settings: theme, filename templates, save format, bulk download wait times, and other preferences
• Downloaded work IDs: IDs of works and novels you have downloaded, recorded to prevent re-downloading
• Partially downloaded IDs: IDs of multi-page works for which only some pages have been downloaded
• Bulk download resume data: temporary data used to recover from interruptions such as extension updates or browser restarts during bulk downloads. Automatically deleted upon download completion
• Session information: transient data used to coordinate download progress across multiple browser tabs. Volatile and automatically deleted upon download completion

This data is never provided or sold to third parties, and is used solely to provide the Extension's functionality.

Cross-Device Synchronization

The most recent portion of your downloaded work IDs is synchronized through Chrome's built-in chrome.storage.sync feature via your signed-in Google account.
This allows you to share your download history across your own multiple devices.
The synchronization takes place between your browser and Google's account sync service, and no third party, including the Extension's developer, can access this data.

External Communication

The Extension communicates only with the following sites in response to your actions:

• www.pixiv.net: retrieval of work metadata (title, author, page count, etc.)
• i.pximg.net: retrieval of image files, Ugoira content, and ZIP files

No communication is made with any other external service (analytics, advertising, statistics, etc.).

Disclaimer

The Extension is developed for personal use, and the developer assumes no responsibility for any damages or disadvantages arising from its use.
Use of downloaded content is at your own responsibility, in compliance with pixiv's Terms of Service and applicable copyright law.
