Privacy Policy

How Big Timer handles your information. Last updated August 28, 2026.

Summary

Big Timer is designed to run entirely in your browser. The timer itself does not require an account and does not send your timers, labels, or laps to any server. The sections below explain the limited data that is stored on your device and the third-party services that may be used to keep the site running and free.

Data stored on your device

Your preferences (such as theme, sound settings, and the last duration you used) and a running timer’s target end time are saved in your browser’s local storage. This information stays on your device, is never transmitted to us, and can be cleared at any time by clearing your browser’s site data.

Analytics

We may use privacy-friendly, aggregate analytics (Vercel Analytics) to understand overall traffic, such as page views and general performance. These measurements are aggregated and are not used to identify individual visitors.

Advertising and cookies

To keep Big Timer free, this site may display ads served by Google, including through Google AdSense. Third-party vendors, including Google, use cookies to serve ads based on a user’s prior visits to this and other websites.

  • Google’s use of advertising cookies enables it and its partners to serve ads based on your visits to this site and/or other sites on the Internet.
  • You can opt out of personalized advertising by visiting Google Ads Settings.
  • You can opt out of a third-party vendor’s use of cookies for personalized advertising at aboutads.info.
  • Learn more about how Google uses information from sites that use its services at policies.google.com/technologies/partner-sites.

Children’s privacy

Big Timer is a general-audience utility and is not directed at children under 13. We do not knowingly collect personal information from children.

Your choices

Because data is stored locally, you are in control: clearing your browser’s site data removes your saved preferences and any in-progress timer. You can also block or delete cookies through your browser settings, though doing so may affect how ads are shown.

Changes to this policy

We may update this policy from time to time. Material changes will be reflected by the “last updated” date above.
