Privacy Policy
Last Updated: August 5, 2026
This Privacy Policy explains how Murmur ("Murmur," "we," "us," or "our") collects, uses, stores, and protects information when you use our mobile application and related services (the "Service"). Please read this policy carefully. By using Murmur, you agree to the practices described here.
1. Who We Are
Murmur is a voice-first personal memory application that allows users to record thoughts, generate transcripts and titles using artificial intelligence, search their memories, and receive reminders. Our goal is to help you capture fleeting thoughts so they are not lost.
2. Information We Collect
2.1 Account Information
- Name
- Email address
- Firebase user identifier
- Profile information provided through Google Sign-In, where applicable
2.2 User-Generated Content
- Voice recordings you create within the app
- Audio files associated with your recordings
- Transcripts generated from your recordings
- AI-generated titles for your memories
- Search embeddings created to enable memory search
2.3 Metadata
- Recording duration
- Creation timestamp
- Detected language
- App version
- Device information, where required for app functionality or security
2.4 Notification Data
We collect a Firebase Cloud Messaging token to deliver memory reminders and product notifications to your device.
3. How We Use Your Information
We use the information described above to:
- Provide, operate, and maintain the Service
- Process your voice recordings to generate transcripts, titles, and embeddings
- Detect the language of your recordings and translate content where required
- Enable search across your saved memories
- Send reminders and notifications you have enabled
- Authenticate your account and protect against unauthorized access
- Maintain, troubleshoot, and improve the Service
- Comply with legal obligations
4. AI Processing
Murmur uses artificial intelligence, provided through OpenAI's API, to process your voice recordings. This processing includes:
- Speech-to-text transcription
- Language detection
- Translation, where applicable
- Generation of AI titles for your memories
- Generation of semantic embeddings used to power search
Your recordings and related content are transmitted to our AI processing provider solely to perform these functions. We do not use your recordings, transcripts, or other personal content to train AI models unless we explicitly disclose this practice to you and obtain your consent beforehand.
AI-generated outputs, including transcripts and titles, may contain errors or inaccuracies. Please see our AI Transparency Policy for further detail on these limitations.
5. How We Store Your Information
- Audio recordings are stored using Cloudflare R2 object storage.
- Account data, transcripts, metadata, and embeddings are stored in a PostgreSQL database managed through Prisma ORM.
- Backend infrastructure is hosted on Amazon Web Services (AWS) EC2 instances.
6. Third-Party Services
We work with the following third-party service providers to operate Murmur. Each provider processes limited categories of data solely to perform the functions described below.
| Provider | Purpose |
|---|---|
| Firebase | Authentication and push notifications |
| Cloudflare R2 | Audio recording storage |
| Amazon Web Services (AWS) | Backend hosting |
| OpenAI | AI processing of voice recordings, including transcription, translation, and title generation |
| Google Play Services | Android app distribution and authentication support |
These providers are contractually or operationally restricted from using your data for purposes beyond providing services to Murmur, except as required by law.
7. Security
We take reasonable steps to protect your information, including:
- Encrypting data in transit using HTTPS/TLS
- Restricting access to storage systems to authorized systems and personnel
- Processing recordings automatically through our systems
We do not manually review your recordings during normal operations. However, please note that Murmur's current architecture is a client-server model and is not end-to-end encrypted. This means that, unlike some messaging applications, Murmur's systems are technically capable of accessing recordings in order to process and store them. We do not access recordings for purposes other than providing and maintaining the Service, except where necessary to investigate abuse, respond to legal obligations, or address security incidents. For more detail, see our Security and Data Protection Policy.
8. Your Rights

- The right to access the personal data we hold about you
- The right to correct inaccurate information
- The right to delete your account
- The right to delete individual memories
- The right to request an export of your data
- The right to withdraw consent for processing, where consent is the basis for processing
