Privacy Policy
Last updated: October 14, 2025
Thank you for trusting Sonder. We're honored to hold space for your voice — and we take that responsibility seriously.
At Sonder Broadcasting PTY LTD, we are committed to protecting your privacy, your data, and your right to control your voice.
Sonder operates on the following foundational principles:
No advertising-based business model
No sale of user data
No third-party tracking
No algorithmic ranking or social scoring
Anonymity and privacy by design
The Privacy Shield is our commitment to protect your identity and personal information:
Complete anonymity on all published content — your stories are never linked to your account name or profile
Your audio recordings, transcripts, and personal reflections remain private unless you explicitly choose to share
Sonder Broadcasting does not have access to your private stories — only content you choose to publish to the Stream is visible to our moderation team
You control who can see your content through granular privacy settings
We do not profit from your attention, your behaviour, or your content. You are not the product.
End-to-end encryption for all voice recordings and personal content
TLS 1.3 encryption for all data in transit
AES-256 encryption for data at rest
Secure, encrypted cloud infrastructure (AWS with SOC 2 compliance)
Session-based authentication with secure cookie handling
Rate limiting and brute-force protection on all authentication endpoints
Regular security audits and vulnerability assessments
Biometric authentication stored locally on your device only
We use your information to:
Provide and maintain the Sonder platform
Transcribe and tag audio recordings using OpenAI's Whisper API
Allow sharing of Sonders with approved contacts or anonymously
Enable features such as albums, Legacy Collections, and the family tree
Process billing through Stripe
Improve platform security, reliability, and accessibility
We do not share your content with third parties without your explicit consent.
We may collect the following types of personal information:
a. User-Provided Information
Name, email address, and account credentials (for registered users)
Voice recordings and transcriptions ("Sonders")
Emotional tags, metadata, album titles, and notes
Contact entries and relationship context (if added)
b. Automatically Collected Information
Device type, browser version, and operating system
Interaction data (e.g., page visits, errors encountered)
IP address (used for security and fraud detection)
Time and date of access
We do not use third-party tracking cookies. We use anonymized analytics to monitor platform performance and improve user experience.
Transcripts & Accessibility
Note: Automatic transcription is only available for Legacy Subscribers.
For Legacy Subscribers, all voice recordings are automatically transcribed. These transcripts:
Are stored securely and privately by default
Are published alongside a Sonder if you choose to publish it
Are used to support accessibility for hearing-impaired users
Are not translated or used for AI model training without consent
Your content is encrypted and stored securely using industry-standard protocols. Voice data is only sent to third parties in the following limited cases, strictly for the purpose of providing core platform functionality:
OpenAI Whisper: Used only for transcription (audio is not retained)
Stripe: Used for payment processing
Cloud Hosting Providers: Secure storage of encrypted data
Biometric authentication, if enabled on your device, remains entirely local — we do not store or transmit biometric data.
All Sonders are private by default. You control who sees your content:
Keep it private
Share with specific contacts
Publish anonymously to the public stream
Published Sonders include their transcript to support accessibility.
Your identity is never revealed - all public stories remain anonymous
You may not share other users' Sonders outside of the platform without explicit permission
You may, at any time:
Download all of your data and recordings
Delete any individual Sonder
Delete your account entirely
Update contact and privacy preferences
Opt out of location features and discovery
Adjust billing and subscription settings
We do not use deceptive design. Exiting Sonder or managing your data is straightforward and clearly presented in your account settings.
