Nippon FC Privacy Policy

Last updated: November 13, 2026

Nippon FC is developed by Happy House Marketing Agency. This policy describes information processed to operate Nippon FC on iPhone and Android. Contact: sam@happy-house.io.

Information processed

You can explore core features without providing an email. The app creates a guest identifier to associate your Passport, followed clubs, predictions, points and milestones with your session. You may also provide a username, country and app preferences.

You can optionally save and recover your Passport with email verification or supported Apple sign-in. We process the account identifier and email associated with that sign-in. Password-enabled accounts can sign in with a password on supported Android versions. Authentication is handled by Supabase; verification codes and passwords are not included in our manual product analytics events.

If you enable notifications, we process a push notification token, device platform, language and notification preferences to deliver requested match updates.

We process product usage events and technical information such as device model, operating system, app version and identifiers to understand use and improve reliability. PostHog receives product events associated with an app user identifier. Automatic screen and touch capture are disabled in our current configuration. Sentry receives error reports and diagnostic context, including device and network information. Network services may receive IP addresses when your device connects to them.

RevenueCat processes purchase history and subscription status to manage access to Nippon FC Pro. Apple or Google processes payments. Nippon FC does not receive your full payment card details.

Purposes and providers

We use information to authenticate accounts, preserve and recover Passport history, personalize club content, deliver optional notifications, manage subscriptions, provide support, and analyze and improve the app.

Our service providers include Supabase (authentication and backend storage), Resend (account email delivery), PostHog (analytics), Sentry (error monitoring), RevenueCat (subscriptions), and Expo and the operating-system notification services (push delivery). Sportmonks supplies football data.

YouTube/Google provides embedded video playback. Playing an embedded video or opening an external service may result in that provider processing device, network and interaction data under its own privacy practices. Videos may include provider-served advertising. External maps and social links are governed by their respective providers.

Account and data deletion

To delete your account in Nippon FC, open Settings > Privacy > Delete account and confirm. This permanently deletes your Nippon account, Passport and predictions. Delete My Data is a separate device-data reset option. Deleting an account does not cancel an Apple or Google subscription; manage subscriptions in the relevant store.

To request deletion without the app, email sam@happy-house.io with the subject “Nippon FC data deletion” from the email linked to your account. State whether you want to delete your account and associated data or only specific data. We may request information needed to verify ownership.

Choices and retention

Account email, notification permission and optional profile information are not required to explore core features. You can change preferences in Settings and revoke notification permission in device settings.

We retain information for as long as needed to operate the service and fulfill applicable obligations. Account deletion removes your account and associated Passport and predictions from the active app database. Subscription transaction records held by Apple, Google or RevenueCat, and security, diagnostic or backup records, may be retained under the relevant provider’s retention practices or applicable obligations. These records are not a recoverable Passport. Contact us for requests concerning provider-held records.

Children and policy changes

Nippon FC is not directed at children under 13. We do not knowingly seek personal information from children under 13. Contact us if you believe a child has provided personal information.

We may update this policy as the app changes. The update date above identifies the latest version.
