FAQ

Common
questions

Does Dimly conflict with Night Shift?

No, they work independently. Dimly controls brightness and gamma, while Night Shift adjusts color only. You can use both simultaneously.

Does it work with external displays?

Yes. Dimly detects all connected displays and applies brightness and warmth to your built-in screen and external monitors simultaneously.

What happens after the 14-day trial?

The app continues to work with basic brightness control and break reminders. Purchase a license to unlock color temperature, eye relief mode, custom break intervals, and meeting detection.

Can I use my license on multiple Macs?

Yes. Your license is meant for personal use on your Macs. Just paste the key and activate — no internet required.

Can I get a refund?

Dimly is a digital product delivered immediately, so purchases are final. That's why we offer a free 14-day trial — try it fully before buying. If you experience a technical issue, contact support@dimly.io.

Is my data collected?

The Dimly app works entirely offline — no analytics, no tracking, no data collection. The website uses anonymous, privacy-respecting analytics to improve the experience.
