Privacy policy
Effective / updated: 2026-10-04 · Android package com.roulette.reference
Data and local accounts
Local email registration stores your email, display name and a salted password hash on your device. Plaintext passwords are not stored. Outcomes, simulated bets, profit/loss records, language, preferences and limits are stored locally to provide the app's features. There is no developer-operated account database or cross-device sync.
Sign in with Google
When you choose Google sign-in, Google provides your stable account ID, email, display name and a short-lived ID token. Native app code verifies the token's signature, audience, expiry and request nonce. Only verified identity and local session information are stored. Tokens are not persisted, exposed to the WebView or sent to a developer server. The app does not obtain your Google password or request Gmail, Drive or contacts access. Google identities are separate from local email accounts and are not automatically merged.
Advertising
Google AdMob / Mobile Ads SDK and advertising partners may process device and advertising identifiers, IP address, approximate location, app/ad interactions and diagnostics for advertising, measurement and abuse prevention. Free access includes banners, voluntary rewarded ads, interstitials and app-open ads. VIP retains banners. Google UMP presents consent messages where applicable. Android advertising settings let you manage or reset your advertising ID. Third-party retention and choices are governed by their policies. See Google Privacy Policy and Google advertising technologies.
Payments and time zone
Google Play processes VIP subscription payments. The app processes product, purchase and entitlement status to verify VIP access, but does not collect payment card or bank details. Signing out or uninstalling does not cancel a subscription. Automatic time-zone detection contacts ipapi.co; that service receives your connection IP. The app sends no account information and stores only country code, time zone and query time, not the IP. You can choose a manual time zone. See ipapi Privacy Policy.
Retention and deletion
Data is stored in private app storage with Android automatic backup disabled. Google local sessions last up to 30 days and are cleared at sign-out. Records remain available to the same identity. Clear app storage or uninstall to remove local data; delete exported files separately. See deletion instructions. Third parties retain their own data under their policies.
Sharing, contact and updates
The developer does not sell your records or supply local outcomes and profit/loss records to advertisers. Support emails and information you voluntarily send are used to respond to your request; do not send passwords, tokens or card details. Privacy contact: peterman921yt@gmail.com, RoulettePredictor team. This app is not directed at children. Meet applicable local age and legal requirements. This policy will be updated when features or providers change.
