Something not working, or a question about one of our apps? Write to us and a person will read it — we do not run a ticket maze.
How to reach us
Email support@lumostudio.cloud. We reply within one working day, Monday to Saturday.
What to include
The more of this you can give us, the faster it gets fixed:
- The app name, and the version number from the app’s settings or About screen
- Your phone model and Android version
- What you did, what you expected, and what happened instead
- A screenshot or short screen recording, if the problem is visible
Common things
The app crashes on opening
First try Settings → Apps → [app name] → Storage → Clear cache, then reopen. If it still crashes, send us your phone model and Android version — a crash on one specific device is usually a driver or memory issue we can reproduce and fix.
I paid and did not get my purchase
Purchases are handled by Google Play, not by us. Open the Play Store app → your profile → Payments & subscriptions → Budget & order history to confirm the charge went through, then send us the order number and we will restore it.
I want a refund
Refunds inside 48 hours go through Google Play directly, under Order history → Report a problem. After 48 hours, write to us and we will look at it case by case.
I want my data removed
See the data deletion page — it sets out exactly what we hold and how to have it deleted.
Reporting a security issue
If you believe you have found a security problem in one of our apps, email us with the details before disclosing it publicly. We will confirm within two working days and keep you updated until it is fixed.
