Privacy Policy & Data Handling Transparency

CleanAudio Privacy Policy — disclosing GPU subprocessors, us-east processing region, zero backup retention, automatic 24h deletion, and user-initiated deletion controls.

Overview

CleanAudio (cleanaudio.im) provides AI background noise removal, wind noise suppression, room echo reduction (de-reverb), vocal isolation, and account billing services. Because journalists, podcasters, and production studios frequently trust us with confidential interviews and unreleased recordings, this policy explicitly discloses our subprocessors, processing regions, cache lifetimes, automated purge mechanics, and how you can delete your data immediately.

Core Privacy Commitments

  1. Encrypted Transit & Isolated Object Storage: Uploaded media (.mp3, .wav, .m4a, .flac, .mp4, .mov, .webm, .mkv) is transferred exclusively over HTTPS/TLS 1.3 and held temporarily in isolated Cloudflare R2 buckets strictly to complete your requested job.
  2. Zero AI Model Training: We never use customer audio files, video recordings, or voice tracks to train, fine-tune, or evaluate any machine learning or AI models.
  3. No Human Listening & No Archival Media Backups: Audio tensors are processed automatically in stateless containers without persistent media snapshots or archival backups. Human staff cannot listen to your recordings unless you manually email a sample to support for troubleshooting.

How Deletion Works & How You Can Delete Data Immediately

  1. Automated 24-Hour Lifecycle Purge: Every cloud-staged upload and exported output object is governed by a bucket lifecycle rule that executes permanent deletion automatically 24 hours after creation.
  2. Immediate Local Discard During Preview: When auditing any 30-second segment in the workbench, replacing the file or closing the browser tab instantly revokes local blob: URLs and clears browser memory.
  3. Self-Service Account Deletion: Registered users may permanently delete their account and associated usage metadata anytime from Account Security Settings.
  4. Expedited Manual Purge Request: If you handled highly sensitive enterprise or journalistic recordings and want immediate confirmation of deletion, email support@cleanaudio.im with your approximate upload timestamp and filename—our team will verify and purge immediately.
