Privacy Policy
Effective Date: March 16, 2026 | Last Updated: March 31, 2026
unspkn ("the App") is an encrypted messaging application developed and operated by Unspkn ("we," "us," or "our"). This Privacy Policy explains how we collect, use, and protect your information when you use the App.
Our core principle: Your messages are end-to-end encrypted. We cannot read your messages. Encryption keys are stored only on your device and are never transmitted to our servers.
1. Information We Collect
Information You Provide
| Data | Required? | Purpose |
|---|
| Handle (username) | Yes | Account identification, friend search |
| Display name | Optional | Profile display to friends |
| Avatar style/photo | Optional | Profile personalization |
| Phone number | Optional | Contact verification |
We do not require your email address, real name, or date of birth to create an account.
Message Data
- Encrypted message content — Messages are encrypted on your device before being transmitted. We store only encrypted data and cannot decrypt or read your messages.
- Encrypted media — Photos, GIFs, voice messages, and files are encrypted on your device before upload.
- Voice messages — Audio recordings are encrypted on your device before upload. Optional on-device transcription uses Apple Speech Recognition or Google ML Kit and never leaves your device.
- File attachments — Documents, images, audio, and other supported file types are encrypted on your device before upload. File names and metadata are included in the encrypted payload.
- Message metadata — Sender ID, timestamp, message type, and delivery status.
AI Features
- AI conversations — If you chat with Nate (our AI friend) or custom AI personas, your messages are sent to third-party AI services (see Section 5) to generate responses. Message content sent to AI services is not end-to-end encrypted but is transmitted over TLS. AI services process your messages according to their own privacy policies.
- AI memory — With your consent, the AI may store conversation summaries to provide more personalized responses. These memories are stored in your private account data and can be viewed and deleted at any time.
- AI voice — If you use voice replies from AI features, text is sent to a voice synthesis service (see Section 5) to generate audio. The audio is encrypted before storage.
Automatically Collected Data
- Crash reports — Device model, OS version, and error information to help us fix bugs. Does not include message content.
- Usage analytics — Anonymous feature usage patterns to help us improve the App. Does not include message content or personal data.
- Push notification tokens — A device token for delivering message notifications. This token does not identify you personally.
2. Information We Do NOT Collect
- Email address
- Precise or approximate location
- Contacts or address book

3. How We Use Your Information

4. Security
