Subscriptions

Luma Premium is billed through your Apple Account on iPhone, and through your Google Account on Android. To manage, change or cancel your subscription, open Settings > your name > Subscriptions on your iPhone, or Play Store > your profile > Payments & subscriptions on Android, or use "Manage my subscription" in the app settings. To restore a purchase on a new device, open the paywall and tap "Restore purchases": your subscription follows your Apple or Google account.

Your data

Everything Luma knows lives on your device. There is no account to recover and no server to ask: we could not read your journal even if you asked us to. You can erase everything from the app settings, in two taps. More details on the legal & privacy page.

AI conversations

Ask My Chart runs directly on your device: on Apple Intelligence on iPhone, on Gemini Nano on Android. It requires an iPhone 15 Pro or newer with Apple Intelligence enabled in the iOS settings, or a Gemini Nano compatible Android device running Android 12 or later. Everything else in Luma works on any iPhone running iOS 26 and any Android phone running Android 8 or later.
