At Vois, we believe your content is yours—and it should stay that way. This privacy policy explains how we handle data in our desktop application and on our website.
The Short Version
- Your scripts and audio never leave your device. All voice generation happens locally on your machine.
- No cloud uploads. We don't have servers that process your content.
- Your API keys stay with you. If you use third-party AI services, your keys are stored locally and never sent to us.
- Minimal server communication. We transmit data for license validation and, for cloned voice exports, a small provenance receipt (no audio, no text, no personal information beyond what the license server already has).
Desktop Application
Local Processing
Vois runs entirely on your computer. When you generate voice audio, the text-to-speech processing happens using models stored locally on your device. Your scripts, audio files, projects, and creative work are never uploaded to external servers.
What We Don't Collect
- Your scripts or text content
- Generated audio files
- Voice samples you provide for cloning
- Voice state files created during cloning
- Project files or settings
- Usage patterns or content analytics
Voice Cloning Privacy
Voice cloning in Vois is designed with privacy as a core principle:
- Local processing only. Voice samples you provide for cloning are processed entirely on your device. The audio is never uploaded to our servers or any third party.
- Voice states stay local. The voice characteristic files (voice states) created during cloning are stored only on your device in encrypted local storage.
- No biometric voice analysis. We do not analyze or classify voice characteristics. A cryptographic hash (SHA-256) of the reference audio is stored locally for provenance verification only. This hash cannot reconstruct the audio.
- You control deletion. Delete any cloned voice at any time. Deleting removes both the voice state and any cached reference audio from your device.
For detailed terms on voice cloning usage, consent requirements, and prohibited uses, see our Voice Cloning Terms.
Subscription Validation
To verify your subscription is active, the app periodically contacts our license server. This communication includes:
- Your subscription account identifier
- A device identifier (to enforce device limits)
- App version information
This data is used solely to confirm your subscription status and enforce device limits. We do not track what text you generate or record your audio output.
Export Provenance
Exported audio files contain metadata identifying them as AI-generated by Vois (a unique export identifier, app version, and voice type). This metadata does not contain your personal information, your script text, or any audio content.
When you export audio that uses a cloned voice, the app sends a small provenance receipt to our server containing: the export identifier, your license key, the cloned voice identifier, the audio duration, and a hash of your device fingerprint. No audio, text, or personal information beyond what the license server already has is transmitted. This receipt supports compliance with synthetic media regulations and enables forensic verification if the audio is misused.
Cloned voice generations are also logged locally on your device (timestamps, anonymized hashes, no text or audio). These logs are automatically pruned after 90 days (1 year for exported generations).
Third-Party AI Services
Vois supports optional integrations with AI services like OpenAI, Anthropic, Google Gemini, OpenRouter, and others for optional AI features. You can connect to these services in two ways:
- Bring Your Own Key (BYOK). You can provide your own API keys. Your keys are stored locally on your device in encrypted storage—never on our servers.
- OAuth sign-in. For supported providers like OpenRouter and Google Gemini, you can sign in directly using OAuth. This connects your account without sharing your credentials with us.
- Direct communication. When you use AI features, your requests go directly from your device to the third-party service provider. We are not an intermediary.
- Their privacy policies apply. Any data you send to these services is governed by their respective privacy policies, not ours.
AI Model Processing
Vois uses open-source AI models for text-to-speech generation and voice cloning. All model inference runs locally on your device:
- No training on your data. Your scripts, audio, and voice samples are never used to train or fine-tune AI models. The models ship pre-trained and run in inference-only mode.
- No model telemetry. The AI models do not phone home, report usage statistics, or transmit any data to model creators or third parties.
- Model files stored locally. AI model weights are downloaded during installation and stored on your device. They are not shared with or accessible by us or any third party.
For details on the open-source licenses governing these models, see our Terms of Service.
Local Storage
Vois stores data locally on your device, including:
- Application settings and preferences
- Project files and scripts (in SQLite database)
- Generated audio cache
- Voice model files
- API keys (encrypted)
This data remains on your computer and is never transmitted to us. You can delete it at any time by uninstalling the application or clearing the application data folder.
Cloud Sync (Optional)
Vois offers optional cloud sync functionality that allows you to backup and restore your projects using third-party cloud storage services such as Google Drive, Dropbox, and potentially others in the future. When you enable cloud sync:
- You control the connection. You sign in directly to your cloud storage provider using OAuth. We never see or store your cloud storage credentials.
- Your data goes to your account. Backups are stored in your own cloud storage account, not on our servers.
- Their privacy policies apply. Data stored in Google Drive, Dropbox, or other services is governed by their respective privacy policies.
Cloud sync is entirely optional. The application works fully offline without it.
Payment Processing
Subscription Billing
Vois uses third-party payment processors to handle subscription billing. When you subscribe, the following information is transmitted to our payment processor:
- Email address
- Billing address (optional)
- Payment method information (credit card, etc.)
Payment data is encrypted and handled directly by our payment processor. We do not store your full credit card details on our servers. For payment processing details, see your payment processor's privacy policy.
Website
Analytics
We use Google Analytics on our marketing website (vois.so) to understand how visitors find and use our site. This includes:
- Pages visited and time spent
- Referral sources
- General geographic region (country/city level)
- Device type and browser
This data is anonymized and used in aggregate to improve our website. You can opt out of Google Analytics by using a browser extension or enabling "Do Not Track."
Newsletter & Waitlist
If you sign up for our newsletter or waitlist, we collect your email address through MailerLite. We use this to send you product updates and announcements. You can unsubscribe at any time using the link in any email we send.
Cookies
Our website uses minimal cookies for essential functionality and analytics. These cookies do not track you across other websites. We do not use cookies for advertising or retargeting.
Data Security
We take security seriously. Our license server uses HTTPS encryption for all communications. API keys stored locally in the desktop app are encrypted. We do not store your content, so there is nothing to breach.
Third-Party Services
We work with the following service providers:
- Cloudflare – Website hosting and license server infrastructure
- Google Analytics – Website analytics
- MailerLite – Email newsletter service
Each of these services has their own privacy policy governing how they handle data.
Your Rights
You have the right to:
- Access your data – Request a copy of any personal data we hold about you
- Delete your data – Request deletion of your personal data from our systems
- Opt out – Unsubscribe from marketing emails at any time
- Control local data – All application data is stored locally and under your control

We may update this privacy policy from time to time. We will notify you of significant changes by posting a notice on our website or within the application. Continued use of Vois after changes constitutes acceptance of the updated policy.
