Terms of use

Using the free tool

You can use Yeolmae Timer without an account or payment. You choose durations and decide whether to enable sound, save browser data or share a link. You remain responsible for checking that the selected time and device settings fit your intended use.

Timing and alarm limitations

This browser tool is intended for everyday focus, breaks, rehearsals and similar tasks. It is unsuitable as the sole timer for medical, emergency, safety or other situations in which a delayed or missing alarm could cause harm.

A device clock change can affect the timer. A suspended browser, locked phone, sleeping device, closed tab or muted audio can prevent or delay sound. Use an appropriate dedicated alarm or other independent timing method when reliable notification is required.

Acceptable use and content

Do not use the site to disrupt its operation, bypass access controls, insert malicious code or place unreasonable automated demand on the service. Share timer settings responsibly; links do not grant access to another person’s private browser data.

The application, guide text and branding are published by Yeolmae Apps. Links may be shared and the tool may be used in ordinary personal, classroom and workplace activities. Republishing the site’s original text, code or branding must respect the permissions and rights that apply to that material and to any third-party components.

Changes, support and your rights

Features and these pages may change as the tool develops. We may correct errors or adjust availability; a saved browser state is not a guarantee of permanent storage. The published contact method is available for questions and problem reports.

These terms do not remove rights that applicable law gives you and does not permit us to exclude. They do not promise uninterrupted operation. Review the current version and the privacy notice when a change affects how you use the tool.
