10. Frequently Asked Questions

Q1: Do I need to keep Chrome open for alarms to work?

A: Yes. Chrome must be running (but can be minimized). The extension cannot trigger alarms if Chrome is completely closed.

A: No. Alarms only trigger when your computer is active. They will trigger as soon as you wake your computer if the time has passed.

Q3: Can I use this extension on my phone?

A: Only if you’re using Chrome on Android (not iOS). iOS doesn’t support Chrome extensions. For full functionality, use it on desktop Chrome.

Q4: Is my data private?

A: Yes! All alarm data is stored locally on your device. We don’t collect, store, or transmit your personal information. See our Privacy Policy for details.

A: Currently, you can only choose from the 8 built-in sounds. Custom sound upload may be added in a future update.

A: This is a harmless warning that doesn’t affect functionality. It will be fixed in the next update.

A: Yes! Use “Custom” repeat type and enter the interval in minutes (e.g., 120 for every 2 hours).
