Privacy Policy

This Privacy Policy explains how Tools Hub("we", "us") treats information when you visit https://hkxoptima.com and use our tools. We designed the product so that your files and encoded content stay in your browser whenever possible.

1. Summary

• You do not need an account to use the QR Code Generator or PDF Editor.
• Tool processing (QR generation and PDF editing) is performed in your browser. We do not operate a server-side upload pipeline for those files.
• Third-party services such as Google AdSense may collect data as described below to show ads and measure performance.

2. Information we process

Content you enter into tools. Text or URLs you type into the QR generator, logos you attach, and PDF files you open are handled locally in your browser session for the purpose of providing the feature. We do not require you to create a profile and we do not intentionally store those files on our application servers.

Technical / usage data. Like most websites, hosting and analytics or advertising partners may automatically receive standard request data such as IP address, browser type, device information, referring pages, and timestamps when pages are loaded.

3. Cookies and advertising

Tools Hub may use Google AdSense to display advertisements. Google and its partners may use cookies or similar technologies to serve ads based on your prior visits to this or other websites. You can learn more about how Google uses data at Google's Partner Sites Policy, and manage personalized ads via Google Ads Settings.

We may also use essential cookies or local storage needed for theme preference (for example light/dark mode) and basic site functionality.

4. How we use information

Information related to site visits may be used to:

• Operate, secure, and improve the website
• Understand aggregated traffic and feature demand
• Display relevant advertising and measure ad performance
• Respond to contact requests you send us

5. Data sharing

We do not sell your personal information. Service providers involved in hosting, advertising (such as Google), or security may process limited technical data as needed to provide their services under their own policies.

6. Data retention

Because tool content is processed in your browser, clearing your browser data removes local session artifacts. Server logs and advertising partners retain data according to their own retention schedules.

7. Children's privacy

The site is not directed at children under 13 (or the equivalent minimum age in your jurisdiction). We do not knowingly collect personal information from children.

8. Your choices

You can stop using the site at any time, adjust browser cookie settings, use ad personalization controls provided by Google, and contact us with privacy questions.

9. Contact
