Is 速読補助ツール safe to install?

What data it declares

The developer declares that it does not collect or use your data.

The developer also certifies that your data is not sold to third parties outside approved uses, not used for purposes unrelated to the extension's core function, and not used to decide creditworthiness or lending.

The listing does not link to a privacy policy.

This is the developer's own declaration in the Chrome Web Store. We cannot check it against what the extension does.

What Chrome asks you to allow

When you add it, Chrome asks you to allow it to:

• Read and change your data on a number of websites

Derived from the manifest by Chrome's documented rules; the dialog's exact wording depends on your Chrome version and language. Chrome asks again if an update requests more.

What it can reach

No site access is declared in the manifest, so it cannot read the pages you open on its own.

We have not read this listing's manifest since we started keeping permission names. The counts on the card come from the last time we did.

Pages it runs its code on

It runs its own code on specific pages only: 4 site patterns.

• https://note.com/*/n/* only note.com
• https://ncode.syosetu.com/* only ncode.syosetu.com
• https://kakuyomu.jp/works/* only kakuyomu.jp

A content script is code the extension injects into pages matching these patterns. On those pages it can read and change what you see, whether or not a host permission is listed above.

What the store shows

The store shows none of its badges on this listing. Most listings carry none.

Has it asked for more over time?

This is the question a permission list on its own cannot answer. An extension that shipped narrow and widened later is a different proposition from one that always asked for the same thing.

The permissions this extension requests have not changed since we started watching it.

Who publishes it

inunuma2, who publishes 2 listings we track. This listing has been in the store since 2023-06-05 and was last updated on 2024-09-26.

How to check or remove it in Chrome

1. Type chrome://extensions in the address bar and find the extension in the list.
2. Open its details. The site access setting shows where it can run; set it to run only on click and it reaches a page only after you press its icon.
3. To uninstall it, choose Remove on the same page.
