This document describes how the Drumbro iOS application handles user information.

What we collect

Drumbro does not collect, transmit, or sell any personal information. The app does not include analytics, advertising identifiers, crash reporting, or any third-party SDKs.

What is stored on your device

The app uses iOS UserDefaults to store the following on your device only:

• High score
• Best level reached
• Tutorial progress (whether you have seen the first-launch tutorial)
• Settings preferences (haptics on/off, sound on/off, reduce-motion on/off)

This data never leaves your device. It is removed when you delete the app.

Network access

Drumbro does not make network requests. The app works entirely offline.

System features

Drumbro uses two iOS frameworks at gameplay time:

• Core Haptics drives Taptic Engine vibrations.
• AVAudioEngine plays short percussive sounds. The sounds are synthesised inside the app at runtime; no audio recordings are bundled, downloaded, or collected.

Both run only while the app is in the foreground. Audio uses the "ambient" audio session category, which means iPhone's silent switch mutes Drumbro and other apps' audio (Music, podcasts) keeps playing.

Drumbro does not request access to the microphone, camera, contacts, photos, location, or any other privacy-sensitive system feature.

App Clip

The Drumbro App Clip plays a single round of a chosen rhythm pattern when launched from a Universal Link. The clip is ephemeral. It does not persist anything to your device, does not collect any data, and does not make network requests. The pattern slug from the URL is read once into memory and forgotten when you close the clip.

Children

Drumbro is rated 4+ and is intended for general audiences. The app does not collect any information from any user, including children. The app does not contain ads, in-app purchases, or links to external sites.

Changes

If this policy changes, the updated text will be available at this URL. The version is identified by the "Last updated" date at the top.
