Privacy Policy

This Privacy Policy explains how OnlineRuler.site ("we," "us," or "our") collects, uses, and protects information when you use our online ruler and related measurement tools (the "Service"). We are committed to keeping your data minimal and your privacy intact. By using the Service, you agree to the practices described below.

1. Information We Collect

OnlineRuler.site is designed to work without requiring you to create an account or submit personal details. The information involved falls into three categories:

Information stored only on your device. Your calibration settings, preferred measurement unit, and theme choice are saved in your browser's local storage. This data never leaves your device and is not transmitted to our servers. You can clear it at any time through your browser settings.

Information you provide voluntarily. If you email us or use a contact form, we receive the details you choose to share (such as your name, email address, and message) so we can respond to your inquiry.

Automatically collected technical data. Like most websites, our hosting provider and analytics tools may log standard technical information such as browser type, device type, approximate region, referring page, and pages visited. This helps us understand usage trends and improve the Service.

2. How We Use Information

We use the limited information we collect to:

• Operate, maintain, and improve the online ruler and related tools.
• Remember your calibration and display preferences between visits.
• Respond to questions, feedback, or support requests you send us.
• Analyze aggregate usage so we can prioritize features and fix problems.
• Display advertising that helps keep the Service free.

3. Cookies and Similar Technologies

Cookies are small text files stored on your device. We use a minimal set of essential cookies and local storage to remember your preferences. Third-party partners, including advertising and analytics providers, may also set cookies to deliver and measure ads. You can control or delete cookies through your browser settings, and you can manage non-essential cookies through our consent banner when it appears.

4. Third-Party Advertising (Google AdSense)

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

• Google's use of advertising cookies enables it and its partners to serve ads to you based on your visits to our Service and/or other sites on the Internet.
• You may opt out of personalized advertising by visiting Google Ads Settings.
• You can also opt out of third-party vendor cookies for personalized advertising at www.aboutads.info.

For more information about how Google uses data when you use our partners' sites or apps, see Google's policy page.

5. Analytics

We may use analytics services (such as Google Analytics) to understand how visitors interact with the Service. These tools collect aggregated, non-identifying usage data such as page views and session duration. We do not use analytics to identify individual users.

6. Your Privacy Rights

GDPR (European Economic Area, UK). If you are located in these regions, you have the right to access, correct, delete, or restrict processing of your personal data, and to object to processing or request data portability. Because we store almost no personal data, most requests can be satisfied simply by clearing your browser storage.

CCPA (California). California residents have the right to know what personal information is collected, to request deletion, and to opt out of the "sale" of personal information. We do not sell personal information.

To exercise any of these rights, contact us at hello@onlineruler.site. We will respond within the timeframes required by applicable law.

7. Data Retention and Security

Preference data stays on your device until you clear it. Any messages you send us are retained only as long as needed to address your request. We apply reasonable technical and organizational measures to protect information, but no method of transmission or storage is completely secure.

8. Children's Privacy

The Service is not directed to children under 13, and we do not knowingly collect personal information from them. If you believe a child has provided us with personal data, please contact us and we will delete it.

9. International Users

The Service may be accessed from around the world. By using it, you understand that any information processed may be handled in countries with data protection laws that differ from those in your jurisdiction.

10. Changes to This Policy

We may update this Privacy Policy from time to time. When we do, we will revise the "Last updated" date above. Significant changes will be highlighted on this page. Continued use of the Service after changes take effect constitutes acceptance of the revised policy.
