Privacy Policy

Last updated: January 15, 2025

At ClockTools, we believe your privacy is fundamental. This policy explains what information we collect, how we use it, and the choices you have. The short version: we collect minimal data, store user settings locally on your device, and never sell your personal information.

1. Our Privacy Philosophy

ClockTools is designed with privacy at its core. Unlike many online services that require accounts and cloud storage, we've built our tools to function with minimal data collection:

  • No account creation required
  • No personal data stored on our servers
  • Your settings (alarms, preferences, saved cities) are stored locally in your browser
  • We don't track your alarm times, timer usage, or other tool interactions

2. Information We Collect

2.1 Information You Provide

If you contact us through our contact form or email, we collect:

  • Your name and email address (to respond to your inquiry)
  • Any information you choose to include in your message

This information is used solely to respond to your inquiry and is not shared with third parties.

2.2 Automatically Collected Information

When you visit ClockTools, we automatically collect certain technical information:

  • Device Information: Browser type and version, operating system, device type (desktop, mobile, tablet)
  • Usage Information: Pages viewed, time spent on site, features used (aggregated and anonymized)
  • IP Address: Used for general geographic location (country-level) and security purposes
  • Referral Information: The website or search engine that directed you to ClockTools

This information helps us understand how people use our tools, identify technical issues, and improve the user experience. It is collected in aggregate form and is not linked to individual users.

2.3 Local Storage

ClockTools uses your browser's localStorage to save:

  • Your alarm settings (times, sounds, repeat schedules)
  • Timer preferences (default durations, sound settings)
  • Saved cities in World Time
  • Theme preferences (dark/light mode)
  • Other tool-specific settings

This data remains on your device and is never transmitted to our servers. You can clear this data at any time through your browser settings.

3. Cookies and Tracking Technologies

3.1 Essential Cookies

We use minimal essential cookies for basic site functionality, such as remembering your theme preference during a session.

3.2 Analytics

We use privacy-focused analytics to understand site usage patterns. This helps us identify which tools are most popular, where users encounter issues, and how to improve the experience. Analytics data is aggregated and anonymized.

3.3 Advertising

ClockTools displays advertisements through Google AdSense to support free access to our tools. Google and its advertising partners may use cookies to serve ads based on your browsing history. You can opt out of personalized advertising by visiting:

4. How We Use Your Information

The limited information we collect is used to:

  • Provide and maintain our time tools
  • Respond to your inquiries and support requests
  • Analyze usage patterns to improve our tools
  • Detect and prevent technical issues or abuse
  • Display relevant advertisements (through third-party ad networks)
  • Comply with legal obligations

5. Information Sharing

We do not sell, trade, or rent your personal information. We may share information only in these limited circumstances:

  • Service Providers: We use third-party services for hosting, analytics, and advertising. These providers process data on our behalf under strict confidentiality agreements.
  • Legal Requirements: We may disclose information if required by law, subpoena, or other legal process.
  • Protection: We may share information to protect the rights, property, or safety of ClockTools, our users, or others.
  • Business Transfers: In the event of a merger, acquisition, or sale of assets, user information may be transferred to the acquiring entity.

6. Data Security

We implement industry-standard security measures to protect your information:

  • HTTPS encryption for all data transmission
  • Regular security audits and updates
  • Limited access to any collected data
  • Secure hosting infrastructure

However, no method of transmission over the internet or electronic storage is 100% secure. While we strive to protect your information, we cannot guarantee absolute security.

7. Your Rights and Choices

You have several rights regarding your data:

  • Access: You can request a copy of any personal information we hold about you (primarily limited to support correspondence).
  • Deletion: You can request deletion of any personal information you've provided through contact forms.
  • Local Data: You can clear your locally stored settings at any time through your browser settings (typically Settings → Privacy → Clear Browsing Data → Cookies and Site Data).
  • Opt-Out: You can opt out of personalized advertising using the links provided above.
  • Do Not Track: We respect Do Not Track browser signals where technically feasible.

Our tools may be used by children (such as students using timers for studying), but we do not collect identifying information. If you believe a child has provided us with personal information, please contact us and we will delete it.
