Timerjar is free to use for personal, classroom, and kitchen timing. You can link to any page. You do not get a license to copy the site, the brand mark, or the guides onto another product and present them as your own.
The clocks are a convenience, not a safety system. Do not rely on them for medical timing, life safety, overnight supervision of a person, or any process where a missed alarm could hurt someone. Browsers throttle background tabs, devices sleep, and sound can be muted. If a time matters in that way, use a tool built for it and a person who is responsible for it.
The site is provided as is. It may be unavailable, wrong, or changed without notice. To the extent the law allows, the publisher is not liable for lost time, burnt food, or a class that ran long because a laptop slept. Local laws may give you rights that these terms cannot waive.
Questions about these terms go to hello@timerjar.com.
Questions
Can I use Timerjar in a classroom?
Yes. That is a normal use. The projector and classroom controls are there for that room.
Is the alarm guaranteed?
No. A browser can delay timers in the background, and a muted device will not make a sound. Do not use it as a safety alarm.
