Frequently Asked Questions
How many countdown timers can I create?
You can create as many timers as you need! Whether you are tracking a single exam or managing a dozen different project deadlines, all timers are generated dynamically and securely saved on your device.
Will my countdowns disappear if I close the browser?
No. Zentrova utilizes your web browser's LocalStorage API. Your timers will remain exactly as you left them every time you return to this page using the same browser, completely eliminating the need for an account or login.
Are these timers synced across my phone and computer?
Because this tool is built with a strict client-side privacy architecture, your data is never uploaded to our servers. Therefore, timers created on your phone will not automatically sync to your laptop. You must create them independently on each device.
How does the timer handle different time zones?
The countdown calculations rely on your device's internal system clock and its configured local timezone. If you set an event for midnight, it will trigger exactly at midnight in your current local time.
What happens when the timer reaches zero?
Instead of displaying confusing negative numbers that break the user experience, the timer automatically switches to a celebratory 'It's here!' state once your target date and time have been successfully reached.
