Privacy Policy

Last Updated: April 30, 2026

Joker Fun Lines (“we,” “us,” or “our”) operates the Joker Fun Lines mobile application (the “App”) and the companion website at jokes0024.com. This Privacy Policy explains what information is collected, why it is collected, and how it is used. Please read it carefully.

Joker Fun Lines is designed to work entirely offline. The joke library ships inside the App bundle, no account is required, and no user content is uploaded to our servers. The limited data described below is collected by the privacy compliance framework embedded in the App, not by the App's joke features.

Information We Collect

Unique Identifiers

We collect the following identifiers through the App's privacy compliance framework:

  • Google Advertising ID (GAID): A resettable advertising identifier provided by the Android platform. It is collected for compliance attribution purposes. You can reset or opt out of personalized advertising at any time in your device settings under “Privacy > Ads.” Google Advertising & Privacy
  • App-Generated User ID: An anonymous UUID generated at first launch and scoped to your device installation. It contains no personal information and is used solely to distinguish individual app installations for aggregate analytics. It is never linked to your name, email address, or any other identifying detail.

Push Notification Token

If you enable the optional daily reminder, the App registers with Firebase Cloud Messaging (FCM) and a device-scoped FCM registration token is generated. This token is used exclusively to route the daily joke reminder to your device. It is not used for advertising or shared with third parties beyond Google's FCM infrastructure. You can disable notifications at any time in your device Settings > Apps > Joker Fun Lines > Notifications.

Firebase Privacy Policy: https://firebase.google.com/support/privacy

Device Information

At the point of consent, the App collects basic device information, including:

  • Device model and manufacturer
  • Operating system version
  • Language and locale settings

This information is used to optimize the App experience for your device and to assist with troubleshooting.

How We Use Information

We use the information described above for the following purposes:

  • Compliance attribution — ensuring the App meets Google Play and Apple App Store policy requirements via the GAID and anonymous User ID.
  • Delivering daily joke reminders — routing push notifications to the correct device via the FCM token (only if you opt in).
  • App optimization — using device model, OS version, and locale to improve compatibility and localization.

We do not use any collected data for advertising profiling, behavioral targeting, or sale to third parties.

Local Data Storage

Joker Fun Lines stores all user-generated content exclusively on your device in a local SQLite database. This includes:

  • Favorites: Jokes you have marked with a heart.
  • Share history: A record of jokes you have shared, stored for convenience.
  • Streak record: The count of consecutive days you have read a joke.

None of this data is transmitted to our servers, synchronized to the cloud, or shared with any third party. It remains on your device until you clear the App's data through your system settings or uninstall the App.

Third-Party Services

The App's privacy compliance framework integrates with Google's advertising and Firebase infrastructure. Their privacy practices govern how they handle data on their end:

Beyond these framework services, the App makes no network requests and does not connect to any analytics, advertising, or tracking platform.

Children's Privacy

The App is not directed at children under 13 years of age, and we do not knowingly collect personal information from children under 13. The joke corpus is general-audience and family-friendly, but the App is intended for users aged 13 and older. If you believe a child has provided personal information through a support request, please contact us and we will take steps to remove it promptly.

Data Retention

The anonymous User ID and GAID are retained only for as long as the App is installed on your device and until you reset the GAID through your device settings. The FCM token persists until you disable notifications or uninstall the App. All locally stored user data (favorites, share history, streak) is retained until you clear the App's data or uninstall.

Your Rights

Depending on your jurisdiction, you may have rights to access, correct, or delete personal data we hold. Because the App is designed to minimize data collection and store user content locally on your device, you already have direct control over most data the App handles. For the compliance-framework data (GAID, User ID, FCM token), you may:

  • Reset or limit the GAID via your Android device settings (“Privacy > Ads”).
  • Disable push notifications and revoke the FCM token by turning off notifications for the App in system settings.
  • Delete all local App data by going to Settings > Apps > Joker Fun Lines > Storage > Clear Data, or by uninstalling the App.
  • Contact us at [email protected] to request deletion of any data held on our systems.

Changes to This Policy

If we update this Privacy Policy, we will revise the “Last Updated” date at the top of this page. We encourage you to review the policy periodically. Continued use of the App after changes take effect constitutes acceptance of the revised policy.
