Lumina Book is a quote and reflection app. It does not ask you to create an account.
Favorites, language, theme, reminder time, the quiet piano setting, and the ad-removal flag are stored on your device with the app's local preferences. Uninstalling the app removes that data. The quote library and the piano recording are part of the app and are not downloaded from a developer server.
Daily reminders are scheduled on the device. They are not sent through a developer server.
Remove ads is a one-time Google Play Billing purchase. Google processes the payment. The app records on the device whether ads were removed.
A banner may appear at the top of the app, and a full-screen ad may appear after every ten quotes or ten answers. "Buy the developer a coffee" in settings plays a rewarded ad that you choose to watch; it is not a payment. Ads are provided by Google AdMob. Google may collect an advertising identifier and related device data under its own policy: Google Privacy Policy.
If you buy ad removal, the app stops requesting ads on that device.
When you share a quote or an answer, the app draws an image on your phone and hands it to the app you pick. Nothing is uploaded to a developer server.
Lumina Book does not provide medical, legal, or financial advice. The book of answers is a comfort, not a prediction.
Lumina Book is not directed at children under 13 and does not knowingly collect personal information from them.
