Privacy Policy

Effective Date: April 5, 2026

1. Introduction

Alter ("we," "our," or "the App") is a playlist curation and management app that connects to your Spotify account. We are committed to protecting your privacy. This Privacy Policy explains what information we access, how we use it, and the choices you have. By using Alter, you agree to the practices described in this policy. If you do not agree, please do not use the App.

2. Information We Access

  • Your playlists — names, track listings, and metadata so you can browse, curate, and manage them.
  • Your listening history — top artists, top tracks, and genre data to power your listening stats and insights.
  • Your profile information — your Spotify display name and account ID to identify your account within the App.
  • Playlist modification permissions — the ability to add and remove tracks from your playlists.

We only access the data necessary to provide the App's features. We do not access your Spotify password, payment information, or private messages.

3. How We Use Your Information

  • Playlist curation — displaying your playlists, allowing you to swipe through tracks, and syncing changes back to Spotify.
  • Listening insights — generating your personal listening statistics such as top artists, top tracks, and top genres.
  • Favorites sync — maintaining your Alter Favorites playlist and auto-syncing it to your Spotify account.
  • Search and discovery — enabling you to search for artists, albums, and tracks to add them to your playlists.

4. Data Storage and Security

Alter does not store your Spotify login credentials. Authentication is handled securely through Spotify's OAuth 2.0 protocol, which never exposes your password. Minimal data may be stored locally on your device to improve performance. This data remains on your device and is not transmitted to external servers unless required for functionality. While we implement security measures, no method of electronic storage is 100% secure.

5. Third-Party Services

  • Alter integrates with Spotify via the Spotify Web API. Your data is subject to Spotify's Privacy Policy.
  • We do not sell, rent, or share your personal information with third parties for marketing or advertising purposes.
  • We do not display third-party advertisements within the App.

6. Data Retention

We retain your data only for as long as necessary to provide service. If you disconnect your account or delete the App, locally stored data is removed from your device. Since we do not maintain external user databases, there is no persistent server-side storage of your personal info.

7. Your Rights and Choices

  • Disconnect your account — revoke Access via Spotify account settings at spotify.com/account/apps.
  • Delete your data — uninstalling the App removes all local data.
  • Request information — contact us to ask what data, if any, we hold.

8. Children's Privacy

Alter is not intended for use by children under 13. We do not knowingly collect personal information from children. If you believe a child has provided data, please contact us for prompt removal.

9. Changes to This Policy

We may update this Privacy Policy from time to time. When we do, we will revise the 'Effective Date' at the top of this page. Continued use of the App after changes constitutes acceptance of the updated policy.
