Frequently asked

How do I get help with an app?

Email us with your device model, OS version, and a short description of the issue. Screenshots help us help you faster.

Where is my data stored?

Each app explains exactly what it stores in its privacy policy. Lumen keeps your account and planning data securely in the EU. See the Lumen privacy policy for details.

How do I request a refund?

Purchases are handled by the App Store or Google Play. Refunds are requested through the store you bought the app from.

Can I suggest a feature?

Yes, please. Halcytron is a solo studio and real feedback shapes what gets built next.

We aim to reply within a couple of working days.
