App Privacy answers (ASC "App Privacy" questionnaire)

Summary: Data Not Collected. Physarum does not collect or transmit any user data.

• Tracking: No. (Manifest: NSPrivacyTracking=false, no tracking domains.)
• Microphone: Audio is analysed on-device into frequency bands to drive the visuals in real time. It is never recorded, stored, or transmitted. → not "collected".
• Photos: Add-only — the app writes captured images/clips to the user's photo library on request. It never reads or collects photos. → not "collected".
• Local network / Bonjour: Used only to connect to the user's own Apple TV on the local network for screen control. No data leaves the local network; nothing collected.
• Required-reason APIs (declared in PrivacyInfo.xcprivacy): UserDefaults (CA92.1, app's own settings), File timestamp (C617.1, pruning the app's own temp files), System boot time (35F9.1, measuring elapsed time for in-app throttling).

In ASC, answer "No, we do not collect data from this app" for every category.
