Privacy Policy

Last updated: 2026-10-08

This policy applies to all of the following Chrome extensions (collectively, the “Extensions”) provided by the operator of this site (the “Developer”).

1. Information we do not collect

The Extensions never send user data — such as browsing history, input content, or page content — to any server operated by the Developer. We also never share data with third parties for advertising, analytics, or tracking purposes.

2. Information stored on your device

Each extension’s feature data is stored only in that device/browser profile, in the browser’s dedicated extension storage (<code>chrome.storage.local</code>). This data is never sent to anyone, including the Developer, and is deleted when the extension is uninstalled. (Exception: Pixel Walker’s settings are stored in <code>chrome.storage.sync</code> as noted below.)

About Pixel Walker: This extension’s settings are stored in the browser’s chrome.storage.sync. If you have Chrome Sync turned on, Google’s own mechanism syncs these settings to your other devices signed in to the same Google account (never to the Developer’s server). To decide where the character can walk, it also calculates the on-screen “position” of text and images inside your browser, but it never saves or sends out the page’s content.

About Price Checker: To periodically recheck the price on a registered product page, this extension automatically opens that page in the background (as a hidden tab). This processing happens entirely within your own device and browser; the page’s content or the result is never sent to the Developer’s server.

3. Payment information (ExtensionPay / Stripe)

Billing for the paid plan (¥300/month, 7-day free trial) is handled by the external payment service ExtensionPay (actual payment processing is done by Stripe). Payment information such as your credit card number never passes through the Developer’s servers and is handled directly by ExtensionPay/Stripe. The only things the Developer can see are your subscription status (trial, active, canceled, etc.) and the email address used to log in.

Please also review ExtensionPay’s and Stripe’s own privacy policies (ExtensionPay, Stripe) for how they handle data. These services may process data outside of Japan (primarily in the United States).

4. About permissions

Some extensions use broad host permissions or content-script permissions to deliver their features (for example, Price Checker’s access to all sites, Form Snippets’ presence on every page to auto-expand “//triggers”, or Pixel Walker’s presence on every page to display its character). In every case, these permissions are used only to run the feature inside your own device and are never used to send collected data anywhere. Each extension’s repository README describes the specific purpose of each permission.

5. Deleting your data

Data stored on your device is deleted when you uninstall the extension. If you would like to delete or request disclosure of payment/subscription information (such as your email address), please contact us using the address below, or contact ExtensionPay support.

6. Age restrictions

The Extensions are not directed at children, and we do not knowingly collect information from children.

7. Changes to this policy

This policy may be updated to reflect changes in law or new features. We will note any significant changes by updating the “Last updated” date on this page.
