Privacy Policy

Last updated: June 9, 2026

FW Smile DevToolsBox ("we", "us", or "our") operates the website at https://devtools.fw-smile.net(the "Service"). This Privacy Policy explains what information we do and do not collect, how it is used, and the choices you have. By using the Service, you agree to the practices described here.

1. Your content stays on your device

All of our tools run entirely in your web browser. The files, images, text, code, and data you process with tools such as the Image Compressor, JSON Viewer, Hash Generator, and JWT Decoder are never uploaded to or stored on our servers. This content is processed locally on your device and is discarded when you close or reload the page. We have no access to it.

2. Information we collect automatically

Like most websites, we and our service providers collect limited technical information automatically to operate, secure, and improve the Service. This may include your IP address, browser type and version, device type, referring pages, the pages you visit, and the date and time of your visit. We use Google Analytics / Google Tag Manager to understand aggregate, anonymized usage patterns (for example, which tools are most popular).

3. Information stored locally in your browser

Some tools save preferences and progress in your browser's localStorage (for example, theme choice, SEO checklist progress, and usage counters). This data lives only in your browser, is not transmitted to us, and can be cleared at any time through your browser settings.

4. Cookies and advertising

We display advertisements through Google AdSense to keep the Service free. Third- party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites.

5. Consent for users in the EEA, UK, and Switzerland

Where required by law, we and our advertising partners obtain consent for the use of cookies and the processing of personal data for personalized advertising through a consent management platform. You can change or withdraw your consent at any time using the privacy/consent controls shown on the Service.

6. How we use information

  • To operate, maintain, and secure the Service.
  • To understand usage trends and improve our tools.
  • To display advertising that helps keep the Service free.
  • To comply with legal obligations.

We do not sell your personal information.

7. Children's privacy

The Service is intended for a general audience and is not directed to children under 13. We do not knowingly collect personal information from children.

8. Your rights

Depending on your location, you may have rights to access, correct, or delete personal data, and to object to or restrict certain processing. Because we do not maintain user accounts or store the content you process, most requests can be handled by clearing your browser data and ad-personalization settings. For other requests, contact us using the details below.

9. Changes to this policy

We may update this Privacy Policy from time to time. Changes are effective when posted on this page, and we will update the "Last updated" date above.
