Frequently asked questions
Is Chess40 free?

How do I delete my account and data?

How do I change my ad choices?
Settings → Privacy → Ad choices. On Android you can also reset your advertising ID; on iOS you can manage tracking in Settings → Privacy & Security → Tracking.
How do updates work?
When a new version is available, Chess40 shows a message in the app and takes you to Google Play or the App Store to update. The website updates itself; when a new version is ready, a small "Update" message appears.
I found a problem. What should I do?
Use Contact support in the app so your message includes the app version and device, and describe what happened and what you expected.
