Privacy Policy

Everything you type stays in your browser and never reaches our servers.

1. Scope

This policy explains how information is handled on Aile Engineer Tools (https://tools.skillbridge.co.jp), a developer tool site operated by SkillBridge Inc.

Our recruiting service "Aile" is governed by a separate privacy policy.

2. What you type into the tools

Every tool on this site (JSON formatting, Base64, hashing, encryption, image conversion and the rest) runs entirely in your browser. The text and files you provide are never sent to our servers, and we never store or read them.

Images you select in the image tools are processed in the browser as well. Nothing is uploaded.

3. What is stored on your device

For convenience, the following is kept in your browser local storage, on your device only. It is never transmitted to us.

- Your recently opened tools (up to 20)

Clearing site data in your browser removes this information.

4. Analytics (Google Analytics)

We use Google Analytics 4, provided by Google LLC, to understand usage and improve the site. It sets cookies and collects information such as pages viewed, referrer, and browser/device type. This data does not identify you by name.

Content you type into the tools is never sent to Google Analytics.

You can opt out with the Google Analytics Opt-out Browser Add-on.

5. Advertising (Google AdSense)

This site uses Google AdSense, a third-party advertising service.

Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this site or other sites.

You may opt out of personalized advertising by visiting Google Ads Settings (https://www.google.com/settings/ads ). You may also opt out of a third-party vendor's use of cookies for personalized advertising at www.aboutads.info.

Content you type into the tools is never shared with advertising vendors.

6. Offline cache

A Service Worker caches pages and tool scripts you have already opened so the site works offline. Only published files of this site are cached — never your input.

7. What we do not collect

This site has no sign-up, no login and no contact form. We do not collect names, email addresses, phone numbers, addresses or work history here.

8. Changes to this policy

We may revise this policy as the site gains features or changes third-party services. Material changes will be published on this page.
