Terms of Service

Last updated: June 30, 2026

By accessing or using onetimer.app (the "Service"), you agree to these Terms. If you do not agree, do not use the Service.

The Service

onetimer provides free, browser-based time tools including an alarm clock, countdown timer, stopwatch, digital clock, Pomodoro timer, and fitness timers (Tabata and HIIT). The Service is provided for personal and commercial use at no charge. Features may change or be removed without notice.

No account required

You may use the Service without creating an account. You are responsible for keeping your device secure and for any activity that occurs through your browser session.

Acceptable use

You agree not to:

  • Use the Service in any way that violates applicable law
  • Attempt to disrupt, overload, or reverse-engineer the Service
  • Scrape or automate access in a manner that imposes unreasonable load on our servers
  • Misrepresent affiliation with onetimer or use our branding without permission

Timers and alarms disclaimer

onetimer runs entirely in your web browser. Alarms and timers require the tab to remain open and your device to stay awake — they are not a substitute for critical wake-up, medical, or safety alerts. We are not liable for missed alarms, inaccurate timing, or consequences of relying on the Service for time-sensitive activities.

Intellectual property

The onetimer name, logo, site design, and original content are owned by us or our licensors. Audio assets used for alarms and ambient sounds are royalty-free (CC0) from third-party libraries as documented in the project. You may embed our tools in third-party sites using the provided embed URLs subject to those platforms' terms.

Disclaimer of warranties

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT.

Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF DATA, PROFITS, OR GOODWELL, ARISING FROM YOUR USE OF THE SERVICE. OUR TOTAL LIABILITY FOR ANY CLAIM RELATING TO THE SERVICE SHALL NOT EXCEED USD $100.

Privacy

Our Privacy Policy describes how we handle data and cookies, including optional Google Analytics with your consent.

Changes

We may modify these Terms at any time. Material changes will be reflected in the "Last updated" date. Your continued use after changes constitutes acceptance.
