Privacy Policy for AirChord

Effective Date: 19 August, 2025

AirChord LLC ("we", "us", or "our") provides a private audio streaming application and web platform ("AirChord") that allows users to digitize and stream their own physical media for personal use. These services are collectively referred to in this policy as the "Service". We are committed to protecting your privacy and being transparent about how your data is used.

1. Information We Collect

We collect limited information to operate and improve the Service:

• Device ID – a unique identifier specific to the installed instance of AirChord (not the physical device), used to associate a stream with your app session and prevent abuse. If you sign in using email in the future, your email address will replace this device ID as your primary identifier.
• IP Address – logged automatically and used for technical troubleshooting, analytics, inferring general location, and preventing abuse.
• Email Address (planned) – if you choose to create an account, we may collect an email address. If you sign in using Apple, you can choose to hide your real email. In that case, Apple will provide us with an anonymous relay email (e.g., xyz@privaterelay.appleid.com), which we use solely to identify your account.

We do not collect:

• Your name
• Contact list
• Exact GPS location

We do not use advertising identifiers or behavioral tracking.

2. Audio Input and Streaming

AirChord accesses your device’s microphone in order to:

• Stream audio from physical media that you own
• Identify songs using the ShazamKit API, which performs audio fingerprinting

Shazam Integration

• Audio snippets are processed on-device by Apple’s ShazamKit API.
• We do not retain or store audio fingerprint data.
• No personal information is shared with Apple or Shazam as part of this process.

3. Data Retention

• We store device IDs and IP addresses for a limited time to support functionality and prevent abuse.
• Email addresses (if collected in the future) will be retained for account access until the user deletes their account.
• Metadata (e.g. stream title, start time) may be stored to support playback and stream management.

4. Your Rights and Choices

If you are concerned about data associated with your device or streams and cannot delete it yourself, you may request deletion of your data by contacting:

privacy@airchord.app

5. Security

We take reasonable steps to protect the integrity of our servers and services, including secure transmission and storage of user data.

6. Changes to This Policy

We may update this Privacy Policy from time to time. The effective date will always be posted at the top of this page. Continued use of AirChord after changes are made constitutes acceptance of the revised policy.
