LottoCheck scans printed lottery tickets and checks them against official winning numbers. In short: there is no account and your ticket photos never leave your device. The app downloads public results data, shows ads (via Google AdMob), uses analytics and crash reporting (via Google Firebase), and — if you enable draw notifications — registers for push messages. The details are below.
LottoCheck does not ask you to register or sign in, and we do not collect your name, email address, or other identity information.
When you scan a ticket with the camera or pick one from your gallery, the numbers are read using on-device text recognition (Google ML Kit). Ticket images are never uploaded to us or to anyone else. The photo is used only to extract the numbers; your scan history and any saved "my numbers" lines are stored locally in the app's private storage on your device.
The app periodically downloads winning-number results compiled from publicly available official lottery sources. Like any internet download, these requests expose standard technical metadata (such as your IP address) to the server providing the data; we do not use it to identify you.
Free versions of LottoCheck show banner ads and an occasional interstitial served by Google AdMob. The app requests non-personalized ads. To serve and measure ads and to prevent fraud, Google may process device information, including the device's advertising identifier and IP address. See how Google uses advertising data. You can reset or delete your advertising ID in Android settings. Purchasing "Remove ads" disables all advertising and the ads SDK is not initialized.
LottoCheck uses Firebase Analytics to understand how the app is used (for example, which features are opened and how often), and Firebase Crashlytics to receive reports when the app crashes so we can fix problems. These tools collect anonymous or pseudonymous usage events, app and device identifiers (such as an app-instance ID), general device information (model, OS version, language), and — for crashes — diagnostic details about the app's state at the time of the crash. This data is used only to keep LottoCheck working and to improve it; it is not used to identify you personally. Google's handling of this data is described in the Google Privacy Policy and Firebase's privacy and security documentation.
If you enable draw notifications, the app registers with Firebase Cloud Messaging and a push registration token for your app installation is collected so we can send you lottery-draw reminders and results alerts. This token identifies the app installation on your device, not you personally, and is used only to deliver these notifications. If you turn draw notifications off (in the app's Settings or in Android notification settings) or uninstall the app, the token is no longer used to reach you. Some reminders may also be scheduled locally on your device without sending anything to a server.
The "Remove ads" purchase is processed by Google Play; we never see your payment details.
Scan history, saved number lines, settings, notification preferences, and the remove-ads entitlement are stored locally and deleted when you clear the app's data or uninstall it.
Lottery content is intended for adults. LottoCheck is not directed at children and is intended for users of legal lottery-playing age in their jurisdiction (18+ in most US states).
LottoCheck is an independent ticket-checking tool and is not affiliated with or endorsed by any lottery operator. Always verify wins with the official lottery operator or an authorized retailer.
If the app's data practices change, this policy will be updated and the effective date revised before that version ships.
