Summary
Check Huay is an unofficial third-party app that lets you check Thai Government Lottery (สลากกินแบ่งรัฐบาล) results against the official GLO API. The app does not require an account, does not collect personally identifiable information, and does not use analytics or advertising SDKs.
What the app stores on your device
| Data | Where | Why |
|---|---|---|
| Lottery numbers you enter manually | Local SQLite database (Drift) inside app sandbox | To populate your check history. You can delete entries at any time from the History screen. |
| Selected draw dates you’ve checked | Same local database | Same purpose. |
| Theme preference (system / light / dark) | iOS / Android user defaults | Remembers your appearance choice. |
| Language preference | iOS / Android user defaults | Remembers UI language. |
This data never leaves your device. It is not synced, not backed up to our servers (we have no servers), and not shared with third parties.
What the app sends over the network
The app calls the official Thai Government Lottery (GLO) API at
https://www.glo.or.th to fetch and verify draw results. Each network
request can include:
- The draw date you selected
- The lottery numbers you ask the app to check (only when you press “Check”)
- A language hint (
thoren) in the request header
GLO is an arm of the Royal Thai Government. We do not control GLO’s privacy practices; please refer to GLO’s own policy. We do not store, log, or transmit your requests anywhere else.
Camera
When you scan a lottery ticket barcode or QR code, the app uses your device camera to decode it on-device. Captured images are never saved or transmitted. Decoded numbers are populated into the input field for you to confirm before you submit a check.
Permissions
| Permission | Why | Optional? |
|---|---|---|
| Camera | Barcode / QR scanning of paper tickets | Yes — only requested if you tap “Scan”. |
The app does not request location, contacts, microphone, photos, calendar, Bluetooth, or push notification permissions.
Children’s privacy
The app does not knowingly collect data from anyone of any age. It does not require an account.
Third-party SDKs
- GLO API (network): destination only, no SDK.
- No analytics SDKs. No advertising SDKs. No crash-reporting SDKs at this release.
Account deletion
The app has no remote account. To delete all data the app has stored:
- Open the app → History → swipe to delete individual entries, or
- Reinstall or uninstall the app — all local data is removed with it.
