Privacy Policy

Last Updated: September 22, 2026

1. Overview and Privacy Philosophy

At HK Smart Tools (accessible via https://hksmarttools.com), visitor privacy is our highest technical priority. Unlike many online tools websites that upload user data to remote servers for processing, HK Smart Tools is intentionally engineered to execute calculations directly inside your web browser.

2. Information We Do NOT Collect

  • Calculation Inputs: Your financial numbers, loan terms, weight, height, dates, text passages, and generated passwords are never transmitted to our servers or stored in any remote database.
  • User Accounts: We do not operate a user registration or account login system. You can use every tool freely and anonymously without creating an account.

3. Local Storage

We use your browser's standard localStorage solely to remember your UI preference for Dark Mode versus Light Mode (key: hksmarttools_theme). This data stays entirely on your device and is never shared.

4. Information You Voluntarily Provide

If you contact us via our Contact Form or by email, we receive the details you choose to submit (such as your name, email address, and message contents) solely to respond to your inquiry or feature request.

5. Server Logs & Hosting

Our website is hosted on Hostinger. Like standard web servers, Hostinger automatically logs basic technical request metadata (such as IP address, browser user-agent, operating system, and timestamp) for security defense, DDoS mitigation, and server performance monitoring.

6. Third-Party Links & Advertising

HK Smart Tools does not sell or share personal user data with third parties. This website may use cookies and similar technologies. In the future, if non-intrusive advertising (such as Google AdSense) is enabled to help support hosting and infrastructure costs, Google and its partners may use cookies — including the DoubleClick cookie — to serve ads based on your prior visits to this or other websites. You can learn more about how Google uses this data and manage your preferences at Google's Privacy & Terms and opt out of personalized advertising via Google Ads Settings or aboutads.info.
