Madu: Breath & Calm — Privacy Policy Still Studio · Effective Date: 3rd April 2026 · Last Updated: 11th April 2026

1. Introduction

Madu: Breath & Calm ("Madu", "the App", "we", "us", or "our") is developed and operated by Still Studio, a sole proprietorship based in Singapore. This Privacy Policy explains how we collect, use, store, and protect your information when you use the Madu app on iPhone, iPad, or Mac.

We are committed to protecting your privacy and handling your data with transparency and care. Madu is designed with a minimal data philosophy — we collect only what is strictly necessary to provide the app's features.

Wellness Disclaimer: Madu is a wellness tool, not a medical device. While we store support signals to facilitate the app's features, this data is not classified as a medical record and is not used for health-tracking or diagnostic purposes.

By using Madu, you agree to the practices described in this Privacy Policy.

2. Information We Collect

2a. Information You Provide

Display Name When setting up Support Mode, you choose a display name to identify yourself to your support person. This name is stored in Apple's CloudKit infrastructure to enable pairing. It does not need to be your real name — you may use any name you choose.

Support Mode Invite Codes When you generate or redeem a Support Mode invite code, a temporary code record is created in Apple's CloudKit infrastructure. This record is automatically deleted once pairing is complete or after 24 hours, whichever comes first.

2b. Information Collected Automatically

Anonymous Device Identifier Madu uses an anonymous device identifier (identifierForVendor) provided by iOS to identify your device within a Support Mode pairing. This identifier is:

• Linked to your device to maintain your pairing connection, but is not used to identify you personally outside the context of the App
• Randomly generated by iOS and not connected to your Apple ID
• Reset if you uninstall and reinstall the app
• Never used for advertising, tracking, or any purpose outside Support Mode

Support Mode Pairing Data When you pair with a support person, a pairing record is created containing:

• Your anonymous device identifier
