Privacy Policy
Last updated: February 2026
Our Privacy Philosophy
Mumbl is designed with privacy at its core. Your voice recordings are processed entirely on your device using local AI (Whisper). We never receive, store, or have access to your audio data.
What We Don't Collect
- Your voice recordings
- Your transcribed text
- The content you create with Mumbl
What We Do Collect
To provide the service and manage your account, we collect:
- Account information: Email address for authentication and billing
- Usage metrics: Number of transcriptions (for free tier limits), not the content
- Payment information: Processed securely by Stripe; we don't store your card details
- Device information: Basic device info for app compatibility and support
AI Processing
Local transcription (Whisper): Audio is transcribed entirely on your device. Nothing is sent to any server.
Text formatting: When you use formatting modes (Professional, Casual, etc.), the transcribed text may be processed by AI to improve formatting. This processing uses your text only and is not stored or used for training.
Data Security
We use industry-standard security measures to protect your account information. Your audio never leaves your device, eliminating the primary privacy risk of voice-to-text applications.
Your Rights
You can delete your account at any time, which will remove all associated data from our systems. Contact us at brockthouston@gmail.com for any privacy-related requests.
Changes to This Policy
We may update this privacy policy from time to time. We'll notify you of significant changes via email or in-app notification.
