Privacy Policy

Data stored in your browser (local data)

The following data is stored in your browser's IndexedDB / sessionStorage and is not sent to a server.

• Scoring results and scoring history
• Recording data (recordings of your singing voice)
• Practice records (results of sustained-note and scale practice)
• Vocal range test results
• Melody cache (analysis results for a song's guide melody)
• AI model cache (MDX-NET model files)
• Microphone settings (device ID and gain value)

Account information (when using social login)

If you sign in with a Google, LINE, or X account, the following information is stored in a cloud database. If you do not sign in, this data is not collected.

• Display name and profile image URL
• Email address
• Authentication provider's user ID
• Scoring results (when cloud sync is enabled)

Ghost race feature and battle feature (when opted in)

Only when you turn on the ghost race feature and update your personal best for a song, the following information is sent to a server and published. When it is off, this information is not sent.

• Pitch trajectory (ghost trace): an array of numeric values representing your pitch while singing, downsampled to 10 Hz and 0.1-semitone units. This is not audio data and cannot be played back or reconstructed as a recording. It contains no information that could identify or reproduce a voice, such as voice quality, formants, phonemes, volume, consonants, or breathing. Silent and unvoiced segments are removed before the data is sent to the server.
• Scores and score breakdowns posted to a battle room

This information is published in association with a public ID (pseudonym), not your account ID, and can be viewed by other users. It can be deleted via the delete action on the scoring result screen or by deleting your account.

Data we do not continuously collect or store: Audio data (singing voice / microphone input), the contents of music files, location data, and device contacts
