1. Data Collection

EchoTag is a local-first music management application. We do not collect, store, or transmit your personal data or music files to any remote servers.

• All music files remain on your local device.
• All tags, lyrics, and metadata are stored locally.
• No user account or registration is required.

2. AI Features

AI-powered features (auto-tagging, lyrics translation) send song metadata and lyrics text to our AI processing service. This service acts as a proxy to AI providers and does not permanently store your data. All processing is done in real-time and data is discarded immediately after the response is returned. No music files or personal identifiers are transmitted.

3. License Activation

When activating a license, a device fingerprint (hardware hash) is generated locally to enforce the 3-device limit. This fingerprint is not linked to any personal identity.

4. Third-Party Services

We use the following third-party services to provide music metadata and lyrics:

• iTunes API: For searching song metadata (title, artist, album, cover art).
• MusicBrainz: Open music encyclopedia for artist and release information.
• Discogs API: For album details and genre information.
• Lrclib: For searching and downloading song lyrics.
• AI Service: For auto-tagging and lyrics translation (real-time proxy, no data storage).
