Home / Privacy Policy & Disclaimer
Last updated: September 18, 2026
This Privacy Policy explains how Web Tools Box ("we", "this site") handles personal information and the data you enter, so that you can use our tools with peace of mind. It also includes a disclaimer regarding the use of our tools. If there is any discrepancy between this English version and the Japanese version, the Japanese version prevails.
All of our tools run entirely on JavaScript in your browser. The text, images, dates, and other data you enter, as well as the results the tools produce, are never sent to or stored on our servers or any third-party server. All processing happens on your own device.
The same applies to image files used in our image tools: they are not uploaded to a server. When you close or reload the page, the data you entered or generated is cleared from your browser and nothing remains on our side.
The only exception is the IP Address & Device Info tool, which contacts a public API (api.ipify.org) when the page opens (and when you refresh the information) in order to display your public IP address. No data you enter and no device information is sent in this request; as with any internet connection, the service can only see the IP address the request comes from. We do not collect or store your IP address or device information.
We use Google Analytics 4, provided by Google, to understand how the site is used and to improve our content. Google Analytics 4 uses cookies and similar technologies to collect usage data (such as pages viewed, time on page, referrers, and device type) in a form that does not identify you personally.
This data is collected and managed by Google in accordance with Google's privacy policy. You can opt out of data collection by disabling cookies; for details, see Google's Privacy & Terms. You can also disable cookies in your browser settings.
We may use third-party advertising services, including Google AdSense. These ad vendors may use cookies to show ads based on your visits to this site and other websites, in order to display ads that match your interests.
You can opt out of personalized advertising in Ads Settings, or disable cookies used for personalized ads by visiting www.aboutads.info. Even with these ad services, we never obtain or store the data you enter into our tools.
We make no guarantees about the accuracy, completeness, or usefulness of the results produced by our tools (including, but not limited to, passwords, QR codes, compressed images, and date calculations). Please use the tools at your own risk.
We are not liable for any damages, direct or indirect, arising from the use of this site or of the results produced by our tools.
Our content and tools may be changed, added, removed, suspended, or discontinued without notice. We are also not responsible for the content of external websites linked from this site.
We may update this policy without notice due to changes in laws or in how we operate the site. The updated policy takes effect when it is posted on this page. We will announce any significant changes on this page.
If you have questions about this policy, please contact us using the form on our About & Contact page.
