Your data, in plain language.

Information used to provide the app

• Account and sign-in: your email address and authentication status are handled through Supabase Auth. The app uses your account identifier to associate app data with your account. After verified sign-in, the app also stores your email in its private account database so administrators can find and support accounts; it is visible only in the administrator workspace and is included in your account export and deletion.
• Playcards and settings: generated cards, selected games and strategies, schedules, history, match evaluations, and notification preferences are stored so the app can provide saved-account features.
• Account activity: for signed-in members, the app records session start, last seen, approximate active duration, and sign-in source. Session activity records are automatically removed after 90 days.
• Support: messages and ticket status are stored so the support team can respond. Do not include passwords, verification codes, or payment details.
• Security and operations: limited administrative audit and service records are used to protect accounts and maintain the app. Hosting, authentication, email, and other infrastructure providers may process technical connection data under their own privacy terms.

Community sharing is your choice

Public match sharing, matched-number sharing, prize-amount sharing, and state-level community totals have separate controls in My account. They are off by default. Public handles are partially obscured, and state totals are shown only when at least five members have opted in. Prize amounts are self-reported and unverified. You can change your sharing choices later.

Cookies and device storage

Sign-in depends on essential, secure session cookies. The app also uses a short-lived session cookie to measure signed-in activity, plus browser session storage for update handling. The installable app uses a service worker for app updates; account and API data are not intentionally cached for offline use.

Location and age

The app does not ask for precise location or save an IP address in its member profile. You may choose a state or territory for optional community aggregation. The age gate asks for a 21+ declaration and records the declaration rather than retaining your full date of birth. Service providers may process connection details as part of operating their services.

Your controls

My account includes tools to export account data, change sharing preferences, manage notifications, and request account deletion. Account deletion removes associated app data; a minimal closure record remains to prevent the deleted account from being recreated by background work or sign-in. Contact [email protected] for privacy questions or help with these controls.

Services and availability

Supabase provides email authentication. The app is available as a limited soft launch at lotteryprediction.app. Service-provider configuration and retention details may change as the service develops. We will update this notice when those arrangements are finalized.
