Privacy Policy

Last Updated: May 18, 2026

Welcome to 3sec, operated at https://toolboxhub.info ("we", "us", "our"). This Privacy Policy explains how we handle information when you use our website.

Our Core Principle

We do not collect anything you enter into our tools. All tools (QR code generator, word counter, image compressor, etc.) run entirely in your browser. Any data you input never leaves your device.

1. Information We Collect

1.1 Tool Usage Data

None collected. Everything you type, upload, or compute in our tools stays on your device and never reaches our servers.

1.2 Automatically Collected Technical Data

When you visit our website, we may collect:

• IP address (anonymized)
• Browser type and version
• Pages visited and time spent
• Referring website
• Device type (mobile/desktop)

This helps us improve site performance and tool design.

1.3 Cookies and Local Storage

We store small amounts of data on your device to improve your experience:

• Functional: dark-mode preference, frequently-used timezone cities
• Analytics: Google Analytics 4 (GA4) for usage statistics — IP anonymized
• Advertising (planned): Google AdSense for displaying ads

You can clear this data at any time via your browser settings.

2. Third-Party Services

2.1 Google AdSense

We are applying for Google AdSense. Once approved, Google may use cookies (the DART cookie) to serve ads based on your prior visits.

• Opt out at Google Ads Settings
• See Google's ads privacy

2.2 Google Fonts

We use Google Fonts (Inter, Noto Sans TC). When fonts load, Google may receive your IP address. See Google's Privacy Policy.

2.3 Google Search Console

We use Search Console to monitor our site's performance on Google Search. This service does not directly track individual users.

3. Children's Privacy

Our service is not directed to children under 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided personal data, please contact us so we can delete it.

4. Data Security

Because our tools run entirely in your browser, the data you input never leaves your device. We use HTTPS (SSL) encryption for all site traffic.

5. Your Rights

Under GDPR (EU), CCPA (California), Taiwan Personal Data Protection Act, and similar laws:

• Right to know what data we hold (answer: almost none)
• Right to deletion
• Right to opt out of ad tracking (see 2.1)

6. Changes to This Policy

We may update this policy. Changes will be reflected on this page with an updated "Last Updated" date. Material changes will be announced on the homepage.
