Privacy Policy

Last updated: June 2025

Fibo 'n Achi ("the App") is a math practice app published by Jet Enterprise LLC. This privacy policy explains how we handle information when you use the App.

Information Stored on Your Device

The App stores the following information locally on your device:

• Progress data (levels completed, stars earned, best times)
• Settings (practice mode, auto-submit, haptic feedback, etc.)
• Tip and tutorial preferences (e.g., "Do not show again" choices)
• Zone unlock state for the map

Leaderboard and Cloud Data

The App includes an optional leaderboard feature. When the leaderboard is active, the following information is sent to and stored on secure cloud servers operated by Google (Firebase):

• Anonymous user ID: A randomly generated identifier assigned automatically by the App. It is not linked to your name, email address, or any other identifying information.
• Generated display name: A randomly generated nickname (for example, "Cosmic Gecko"). You are not asked to provide your real name.
• Game performance data: The level completed, time taken, and number of hints used. No incorrect answers or other gameplay details are stored.
• Timestamp: The date and time a run was completed, used to calculate rolling 30-day rankings.

This data is used solely to display leaderboard rankings within the App. We do not use it for advertising, analytics, or any other purpose.

Because the anonymous user ID is not linked to any real-world identity, we cannot identify who submitted any particular score.

Students and Families

The App is designed for use by students and families. We do not collect names, email addresses, photos, location data, or any other personal information. Leaderboard data is anonymous by design — no real identity is required or collected at any point.

Parents or guardians who wish to have their child's leaderboard data deleted may contact us at the address below. Because the data is anonymous, we may ask for the generated display name and approximate date of use to locate the relevant records.

Third-Party Services

The App uses Firebase, a platform operated by Google LLC, to store leaderboard data. Firebase's privacy practices are described at firebase.google.com/support/privacy. No other third-party analytics, advertising, or data collection services are used.

Data Deletion

To delete locally stored data, uninstall the App from your device. You may also clear the App's data in your device settings.

To request deletion of leaderboard data stored on our servers, contact us at the address below with your generated display name and the approximate date of use.

Changes to This Policy

If we add features that change what data is collected or how it is used, we will update this policy, indicate the date of the last update, and notify users through an in-app notice or app update notes.
