Yumu Privacy Policy

Last updated: 2026-09-09 · Version: v1.0

1. What we collect.

  • Email address — only if you sign in; used for one-time-code login and account identity.
  • Voice audio — streamed over an encrypted (TLS) connection to our speech service while listening, converted to text, and not stored long-term on our servers; audio is discarded immediately after processing.
  • Transcripts and recordings — stored only on your device; never uploaded (unless a future cloud-sync feature is introduced with your separate consent).
  • Purchase receipts — in-app-purchase transaction tokens sent to our server to credit your quota; they contain no payment-card data.
  • Diagnostics — anonymized error types and timestamps for troubleshooting; never speech content.

2. Permissions. Microphone: active only while listening is on. Local network: only for discovering AirPlay devices on your Wi-Fi.

3. How we use it. Providing speech recognition, account authentication and multi-device management, crediting purchases and usage accounting, and service stability. As of this version's date, we do not sell your personal information, use it for advertising, or embed third-party ad or behavioral-analytics SDKs. Should a future version introduce advertising or such SDKs, we will update this policy first, notify you prominently in-app, and provide ways to opt out as required by law.

4. Storage. Servers are located in mainland China. Your audio is processed only in server memory for the ongoing recognition and is discarded immediately afterwards — never written to disk or stored in a database. Account data is deleted or anonymized after account deletion; diagnostic logs are kept for at most 90 days.

5. Sharing. We do not share your personal information except: with your consent; as required by law or competent authorities; or the minimum necessary with app stores (Apple/Google) to process transactions under their terms.

6. Your rights. You may access, correct or delete your personal information, delete your account, and withdraw consent (uninstalling stops all collection). Contact support@welomo.com — we respond within 15 business days.

7. Children. The Service is not directed to children under 14. If we learn we have collected a child's information, we will delete it promptly.

8. Changes. Material changes to this policy will be announced in-app.
