LottoDost — Privacy Policy

Last updated: 18 October 2026

LottoDost ("the app") shows public lottery results and lets you check your own ticket numbers. It is an independent app and is not affiliated with any government or lottery department.

1. What we collect

We do not collect personal data. There is no account, login, phone number, contacts, location or payment. The app has no advertising and no analytics SDK.

2. Data that stays on your phone

• Saved tickets (ticket number, draw date and time) that you choose to save, so the app can check them when a result is published.
• Settings such as your language and notification choice.
• Downloaded results, cached so the app works offline.

This data is stored only in the app's private storage. It is deleted when you remove a ticket, clear the app's data or uninstall the app.

3. Camera and photos

If you choose Scan ticket, the camera image (or a photo you pick) is read on your phone to find a QR/barcode or the ticket number. Images are not saved and are never uploaded by the app. Camera access is optional; you can type numbers instead.

4. Services used by the app

• Google Play services – ML Kit text recognition and barcode scanning (on-device). Google may collect device and app information, performance metrics and API configuration for diagnostics. See Google's ML Kit data disclosure.
• Result hosting (GitHub Pages, jsDelivr, raw.githubusercontent.com and, if enabled, Cloudflare). When the app downloads results, these providers receive standard request information such as your IP address and device user agent, as with any website. The app sends no identifier or personal data in these requests.
• Firebase Cloud Messaging (Google), used only to tell your phone that a new result is out. To deliver these messages, Firebase creates an app instance identifier and a registration token for your installation. The message we send contains no personal data, only "new result", and every phone receives the same message. See Privacy and Security in Firebase.
• Links you open (official result PDFs, live-draw page) open in your browser and are governed by those websites' policies.

5. Notifications

Result and ticket alerts are written and shown on your phone; your saved tickets are checked on your phone and never sent anywhere. You can turn alerts off, or choose which draws to be alerted for, in the app (Guide → Settings) or in Android settings.

Result PDFs you choose to save are stored in the app's own folder on your phone.

6. Children

The app is intended for adults (18+). We do not knowingly collect any data from children.

7. Changes and contact

We will update this page if the app's data practices change. Contact: yechan750745@gmail.com
