Privacy Policy

Effective July 11, 2026

What Subfluent processes

Subfluent uses your Google account to authenticate you. When you start a live session, microphone audio is streamed directly to Soniox for transcription and translation. The app does not intentionally store raw audio. Final transcript text, language settings, session names, timestamps, and duration are stored so you can reopen and export sessions.

If a transcript cannot be saved immediately, the browser's local IndexedDB storage keeps the pending text on that device until retry or deletion. Standard operational metadata such as request timing, status codes, and error categories may be processed, but transcript text, audio, credentials, and authentication tokens are excluded from application logs.

Service providers

Subfluent relies on Vercel for application hosting, Supabase for authentication and PostgreSQL storage, Google for sign-in, and Soniox for live speech processing. Data may be processed in the regions where those providers operate. No advertising profiles are built and transcript text is not sold.

Retention and your choices

Saved transcripts remain until you delete an individual session, delete all saved sessions, or delete your account. Deleting a session removes its transcript segments. You can export a session before deletion. Backup copies may remain until the applicable backup retention window expires and are not restored except for disaster recovery.

Security and requests

Access controls restrict transcript data to the signed-in account through the application. For an access, correction, export, deletion, or privacy request, email maxluo42@gmail.com. We may need to verify the request through the signed-in account. This policy describes product behavior and is not a claim of compliance with every jurisdiction.
