Privacy Policy

This Privacy Policy explains how EasyUtil ("we," "us," or "our"), operated at easyutil.kr, handles information when you use our services. We are committed to protecting your privacy and being transparent about our practices.

1. Our Core Privacy Principle

All calculations run entirely in your browser. When you enter data into any of our calculators — salary figures, health measurements, dates, financial information — that data is processed locally on your device using JavaScript. It is never transmitted to our servers, never stored in any database, and never shared with any third party. We have no ability to see, access, or recover your calculation inputs or results.

2. Information We Do Not Collect

We want to be explicit about what we do not collect:

• No personal identification information (name, email, phone number, address)
• No financial data (salary, income, loan amounts, tax information)
• No health data (weight, height, BMI, baby growth measurements)
• No calculation results or history
• No user accounts or login credentials (we have no registration system)

3. Information Collected Automatically

For site operation and improvement, certain technical information may be automatically collected through third-party services:

3-1. Google Analytics

We use Google Analytics to understand how visitors interact with our site. This service may collect:

• Pages visited and time spent on each page
• Referring website or search terms that led you to our site
• General geographic location (country/city level, not precise location)
• Device type, browser type, and operating system
• Anonymous usage patterns (page views, bounce rate, session duration)

This data is aggregated and anonymized. We use it solely to improve our calculators and user experience. You can opt out of Google Analytics by installing the Google Analytics Opt-out Browser Add-on.

3-2. Server Logs

Our hosting provider may automatically record standard server logs including IP addresses, access timestamps, and HTTP request details. These logs are used for security monitoring and are automatically deleted within 90 days.

4. Cookies and Advertising

4-1. Google AdSense

We display advertisements through Google AdSense to support the free operation of our service. Google AdSense uses cookies, including the DoubleClick cookie, to serve ads based on your visits to this and other websites.

• These cookies allow Google to show you more relevant ads but do not personally identify you
• You can opt out of personalized advertising at Google Ad Settings
• You can also opt out of third-party vendor cookies at aboutads.info

For more details, see Google's Privacy Policy.

4-2. Kakao AdFit

We may also display advertisements through Kakao AdFit. Kakao AdFit may use cookies and advertising identifiers to serve ads. For details, see Kakao's Privacy Policy.

4-3. Essential Cookies

We may use minimal first-party cookies for essential site functionality such as language preference (Korean/English) and dark mode settings. These cookies do not track you and contain no personal information.

4-4. Managing Cookies

You can control cookies through your browser settings. Most browsers allow you to:

• View what cookies are stored and delete them individually
• Block all cookies or only third-party cookies
• Set preferences for specific websites

Note: Blocking all cookies may affect site functionality, including the display of language preferences.

5. Third-Party Services

Our site integrates the following third-party services, each governed by their own privacy policies:

6. Children's Privacy

Our service is not directed at children under 14. We do not knowingly collect personal information from children. Our baby/parenting calculators are designed for parents and caregivers to input data on behalf of their children — the data is processed entirely in the browser and never collected by us.

7. Data Security

We implement appropriate security measures including:

• HTTPS encryption for all page loads
• No server-side storage of user calculation data
• Regular security updates to our hosting infrastructure
• Content Security Policy headers to prevent cross-site scripting

8. Your Rights

Since we do not collect or store personal data from calculator usage, there is no personal data to access, correct, or delete. For any privacy-related concerns or questions, you may contact us at the email below and we will respond within 5 business days.

9. Policy Changes

We may update this Privacy Policy to reflect changes in our practices or for legal compliance. When we make material changes, we will update the "Last updated" date at the top of this page. We encourage you to review this page periodically.
