Prime Coast Studio LLC ("Prime Coast Studio," "we," "us," or "our") operates the website at primecoaststudio.com (the "Site") and the LottoPrime mobile app for Android (the "App"). This policy explains what information we collect when you use the Site and the App, and how we use it. LottoPrime is an unofficial lottery tools/utility app; it is not affiliated with or endorsed by Powerball, Mega Millions, MUSL, or any state lottery, and it does not facilitate the purchase of lottery tickets or involve real-money play.
The Site is a simple, static marketing site. We don't ask you to create an account or sign in, and we don't sell your information.
The Site does not set tracking cookies or run third-party advertising scripts. We use Cloudflare Web Analytics, a privacy-friendly, cookieless analytics service that measures aggregate Site usage (such as page views and referrers) without setting cookies, storing data on your device, or tracking you across other sites. We load the Inter typeface from Google Fonts; as part of serving those font files, Google may receive your IP address.
We rely on a small number of service providers to run the Site:
Server logs are retained according to our hosting provider's defaults. Any messages you send us are kept only as long as needed to respond to you and to keep a reasonable record of our correspondence.
If you've sent us a message and would like us to access or delete the information it contained, contact us through our contact page and we'll do our best to help, subject to any legal obligations we have to retain it.
The Site is not directed to children under 13, and we do not knowingly collect personal information from them. LottoPrime is intended for adults and is not directed to children under 13.
This section describes data practices specific to the LottoPrime Android app.
Account identifiers. When you first open the App, we create an anonymous account with Google Firebase Authentication so your settings and subscription can be associated with your device — this does not require any personal information. If you choose “Continue with Google” to save or restore your access, we receive your Google account email address and a basic profile identifier to link your account.
Subscription and purchase information. Premium subscriptions are processed by Google Play Billing. Google handles your payment; we do not receive or store your payment-card details. We receive purchase status (such as whether a subscription is active) and store your entitlement (premium status, expiry date, and trial start date) associated with your account identifier in Google Firestore.
Trial-abuse-prevention identifier. To ensure the one-time free trial is granted roughly once per device, we process your device's Android ID solely to compute a one-way, salted hash. We store only this hash — never the Android ID itself — and use it exclusively to detect whether a device has already used its free trial, so that deleting your account or reinstalling the App cannot grant repeated trials. The hash cannot be reversed to identify you or your device, is not linked to your name or contact details, and is not used for advertising, analytics, or tracking. Because it exists for fraud and abuse prevention, we may retain it even after you delete your account (see Retention and deletion).
Usage and diagnostic data. We use Firebase Analytics to understand how the App is used — for example, which screens are opened and when a subscription is started or cancelled — including app-interaction events, an app-instance identifier, and standard device/OS information (such as device model and app version). As part of Firebase Analytics, your device's advertising identifier may also be collected. The App contains no advertising, and we do not use this data to serve ads, build advertising profiles, or track you across other apps or websites — it is used only for first-party analytics about how the App is used.
Information stored only on your device. Your saved sets, app settings, and cached draw results are stored locally on your device and are not transmitted to us. Removing the App removes this data.
Lottery draw data. The App displays public lottery results (winning numbers and draw dates) retrieved from our own backend (Google Firebase), which we compile from public sources. Draw results are public, factual data and contain no personal information about you.
How App data is shared. We share information only with Google services that operate the App's backend on our behalf — Firebase Authentication, Cloud Firestore, Cloud Functions, Firebase Analytics, and Google Play Billing — governed by the Google privacy policy. We do not sell your personal information and do not use it for third-party advertising.
Security. Data transmitted between the App and our backend is encrypted in transit using industry-standard TLS/HTTPS. Entitlement records are stored in Google Firestore under Google's security controls.
Retention and deletion. Account and entitlement data is retained while your account exists so your subscription can be honored across devices. You can delete your account and associated data at any time from Settings → Delete account in the App, or by following the instructions on our account & data deletion page. When you delete your account we remove your account record and entitlement data; the only thing we may retain is the one-way trial-abuse hash described above, kept for fraud and abuse prevention — it contains no personal information and cannot be reversed to identify you. Deleting your account does not cancel an active Google Play subscription — cancel that separately in Google Play.
Your rights. Depending on where you live (for example under GDPR or CCPA/CPRA), you may have rights to access, correct, or delete your personal information, and to object to or restrict certain processing. To exercise these rights, contact us at support@primecoaststudio.com.
We may update this policy from time to time. When we do, we'll revise the "last updated" date above. Material changes will be reflected here on this page.
