Luckwhirl (“the app”) is an independent Android app that shows published lottery results, checks the numbers you save against those results, shows statistics of past draws and offers a ball draw machine for fun. It does not sell tickets, accept bets, link to ticket sales or predict results, and it is not affiliated with any lottery operator. This policy explains what the app does with information. In short: we do not collect any personal information.
To show results, the app downloads public result files from our server at tanzsoft.com. Our server collects these results from the operators' official public sources (dhlottery.co.kr, data.ny.gov, fdj.fr, taiwanlottery.com and caixa.gov.br). The app's requests contain no personal information, no identifiers and none of your numbers. Our web server does not keep access logs for these result files. As with any internet connection, your IP address is necessarily visible to the server while a file is delivered, but it is not stored or used.
Numbers you add, scan or save from the draw machine, and your settings (games you follow, theme, sound), are stored only in the app's private storage on your device. Checking your numbers against results happens on your device. If you turn on Android's own backup for your phone, Android may include the app's data in your Google backup; this is controlled by you in Android settings and we cannot access it. “Export” writes a file with your numbers to a location you choose; that file is under your control.
If you choose “Check with QR”, the app asks for camera access. The camera image is analyzed on your phone to read the QR code printed on a Korea Lotto 6/45 ticket (draw number and the numbers on the ticket). Images are not saved, uploaded or shared. You can also pick a photo with the Android photo picker, which gives the app access only to the photo you select; it is read on your device and not kept. Camera access is optional; everything else works without it.
If you allow notifications, the app checks about once an hour for new results of the games you follow and shows a short notice such as “Results are in”. The notice does not show prizes or your numbers. You can turn notifications off in the app's settings.
The app requests no location, contacts, microphone or storage access. The motion sensor is used only to let you shake the phone to mix the balls; its readings are not stored.
The app is intended for adults aged 18 and over (19 and over in Korea). It is not directed at children.
Past results do not affect future draws, and nothing in the app can make a number more likely to win. Please play only for fun and with money you can afford to lose. If gambling is causing problems, contact a local support service.
You can delete saved numbers in the app at any time. Uninstalling the app removes all of its data from your device. Because we never receive your data, there is nothing for us to delete on our side.
If this policy changes, the new version will be posted on this page with a new date. Questions: tanzsoftkor@gmail.com
