Privacy Policy

Last updated: September 14, 2026

At onlinestopwatch (accessible from https://onlinestopwatch.app/), one of our main priorities is the privacy of our visitors. This Privacy Policy document outlines the types of information collected and recorded by our platform and how we use it.

1. Client-Side Processing & Tool Data

Our online utilities—including our stopwatch, countdown timer, and related time-tracking tools—run entirely on the client side using your browser’s local memory (RAM) and standard web technologies (such as the HTML5 Web Audio API).

  • We do not transmit, record, store, or monitor your timing data, split laps, countdown intervals, or tool inputs on our servers.
  • All tool interactions and active states remain exclusively on your device and are cleared whenever you reset the tool or close your browser tab.

2. Log Files

Like most web servers, onlinestopwatch.app follows a standard procedure of using log files. These files log visitors when they access the website. The information collected by log files may include:

  • Internet Protocol (IP) addresses
  • Browser type and version
  • Internet Service Provider (ISP)
  • Date and time stamps
  • Referring/exit pages
  • Number of clicks

This information is not linked to any personally identifiable information. The purpose of this data is to analyze site trends, administer the platform, track user movement on the website, and optimize server performance.

3. Cookies and Local Storage

onlinestopwatch.app uses standard cookies and local browser storage to store user preferences, such as selected UI display modes (Light/Dark mode) and interface configurations. These identifiers help provide a consistent experience across visits without tracking your personal identity.

You can choose to disable cookies through your individual browser options. Detailed information about cookie management with specific web browsers can be found on each browser’s respective website.

4. Google DoubleClick DART Cookie & Third-Party Advertising

Third-party vendors, including Google, may use cookies to serve ads based on a user’s prior visits to this website or other websites on the Internet:

  • Google’s use of advertising cookies enables it and its partners to serve ads to users based on their visits to our site and/or other sites across the web.
  • Users may opt out of personalized advertising by visiting Google Ads Settings.
  • You can also opt out of third-party vendor cookies for personalized advertising by visiting aboutads.info.

Our Privacy Policy does not apply to other advertisers or third-party websites. We encourage you to consult the respective Privacy Policies of these third-party ad servers for more detailed information on their practices and opt-out procedures.

5. Third-Party Analytics

We may partner with third-party analytics providers (such as Google Analytics) to monitor and analyze web traffic and user behavior patterns. These services collect non-personally identifiable aggregated data to help us improve site navigation, performance, and user interface responsiveness.

6. Children’s Information (COPPA)

Protecting children using the internet is another part of our priority. onlinestopwatch.app does not knowingly collect any Personal Identifiable Information from children under the age of 13. If you believe that your child provided this kind of information on our website, please contact us immediately, and we will promptly remove such records from our systems.

7. Consent
