Privacy Policy

This policy covers the Music Mini Games iOS app and the musicminigames.com website.

Information We Collect

Music Mini Games does not require an account. We never collect your name, email address, or contact information. The app collects a minimal amount of data, none of which is linked to your identity:

• Anonymous Identifier: A random ID generated on your device the first time you play. It is not derived from your device hardware, Apple ID, or any personal information.
• Gameplay Data: Game sessions, daily-challenge results, and aggregate event counters that tell us how the app is used.
• Usage Analytics: Events such as which screens you open and which games you play, tied to your anonymous identifier, along with basic device or browser details. See Analytics below.
• Display Name: A music-themed name our server makes up for you, like "BrassyCadence4271." It is randomly assigned, not chosen or entered by you, and it is what appears next to your scores on the public leaderboards.
• Purchase History: Records of in-app purchases, verified with Apple, so we can unlock what you bought and restore it later.

How We Use Your Information

We use this data to:

• Save your progress, streaks, and daily-challenge results
• Rank scores on the leaderboards under your assigned name
• Process and restore your purchases
• Understand aggregate usage so we can improve the games

What We Don't Do

• No advertising
• No tracking across other companies' apps or websites
• We never sell your data

Where Your Data Lives

Data is stored on our own backend, hosted on infrastructure providers (Fly.io for servers, Crunchy Bridge for the database). We may share data with service providers only as needed to operate the service, such as these hosting providers, PostHog for analytics, and Apple for payment processing.

Data Retention & Deletion

We retain gameplay and purchase data for as long as needed to provide the service. To request deletion of the data associated with your device, email us at the address below and we will remove it.

Children's Privacy

The app collects no personal information from anyone, including children. Everything is stored under an anonymous identifier.

Analytics

We use PostHog, a product analytics service, in the app and in the games at musicminigames.com/games, to learn which features get used and where players get stuck. It receives the events described above under your anonymous identifier, plus basic device or browser details such as the operating system and an approximate location derived from your IP address.

In the web games only, PostHog also records sessions: a replay of what appeared on the page and where you clicked or tapped, so we can see where the games are confusing. Anything you type into a text field is masked and never recorded. The iOS app does not record sessions.

Microphone audio from the singing games is never recorded or sent anywhere. Pitch detection happens entirely on your device or in your browser.

The musicminigames.com website also uses Google Analytics to understand site traffic. The iOS app does not use Google Analytics.

Changes to This Policy

If we make material changes to this policy, we will update this page and the date below.
