SumLotto Powerball (com.win.us_power_ball)
Last updated: August 16, 2026
The SumLotto Powerball app ("the app") is a number-generation and statistics utility. It has no sign-up and no login, and it never asks for your name, e-mail address, or phone number.
Almost everything the app creates stays on your device (section 2). The one exception is the optional Contact us screen: if you choose to send a message there, that message is stored on a server so the operator can reply (section 3).
The app also sends anonymous usage statistics — which screens are opened and which in-app actions are taken — to the analytics service named in section 4. These carry no name, e-mail address, or phone number, and none of the numbers you generate or play are included.
This collection is a required part of using the app: it is what tells the operator which features are worth keeping and where the app is breaking, so there is no in-app switch to turn it off. Because the statistics are anonymous, they cannot be traced back to you. If you would rather not send them at all, uninstalling the app stops them completely.
The following data is created by the app and stays on your device. It is never transmitted to the operator or to any server:
You can remove this data at any time with the in-app "Clear" actions or by uninstalling the app.
The app includes an optional 1:1 inquiry screen. It is used only when you open it and send a message — nothing is transmitted otherwise.
What is stored
Where it is stored — Google Cloud Firestore, in
Google's asia-northeast3 region (Seoul, South Korea). If
you use the app from another country, your message is transferred there
and stored under that country's Google Cloud infrastructure.
Who can read it — only you and the operator. Each conversation is bound to the anonymous identifier that created it, and the server's security rules reject every read and write coming from a different identifier. No other user can see your messages, and each app in the family keeps its inquiries in a separate collection.
Please do not put personal details, payment information, or passwords into a message — the operator does not need them in order to help.
How long it is kept — until one year after the last message in the conversation, then deleted. You can have it removed sooner by asking inside the conversation itself, or by e-mailing the address in section 8.
Uninstalling the app removes the anonymous identifier from your device, so a reinstall starts a new, empty conversation. Messages already sent remain on the server until the retention period above ends or you ask for deletion.
The app uses the following services, each governed by its own policy:
These services operate independently; apart from your own inquiry thread, the operator only sees aggregated statistics.
Your data is never sold — nothing the app collects is shared with data brokers, and the operator does not sell it.
Analytics collection is required — the analytics described above starts automatically with the app, to improve quality and diagnose faults, and the app provides no in-app opt-out. If you do not want it, please stop using the app and delete it.
Transfers outside your country — the PostHog project this app reports to runs in the United States, so the usage statistics described above are transferred to and stored in the US. Google (AdMob, Firebase) may likewise process data on servers outside the European Economic Area. These transfers rely on the recipients' own safeguards, published in the privacy policies linked above. No name, e-mail address or telephone number is involved, and none of the numbers you generate or play leave your device through them.
The first time you open the app, after the splash screen, it asks how the ads should work. Nothing is decided behind your back:
If you say no — or simply close the dialog — the app keeps working exactly the same and you still get the same credits for watching a rewarded ad. Only the ads themselves become generic. You can change your mind at any time in your device settings (iOS: Settings → Privacy & Security → Tracking).
The app never offers a reward, extra credits, or any other incentive for allowing tracking, and the two answers are presented with equal weight.
The app has no in-app purchases and no subscriptions. Challenge credits are earned only inside the app — for example by choosing to watch a rewarded ad. They have no cash value and cannot be bought, sold, transferred, or exchanged for money.
The app is not directed at children and provides no real-money gambling. Simulated draws use virtual credits with no monetary value and no payout.
