Privacy Policy
Last updated: 2026-05-23
LaVoix.ai (“LaVoix”, “we”, “us”) provides an AI-powered research tool that lets you ask questions across multiple YouTube videos. This policy explains what information we collect when you use the service at lavoix.ai, how we use it, who we share it with, and the rights you have over it.
By using LaVoix.ai you agree to this policy. If you don't agree, please don't use the service.
Information we collect
When you sign up
- Email address and name, managed by our authentication provider Clerk.
- If you sign in with Google, we receive your Google account's email and basic profile info — the same data we'd collect if you signed up with a password.
While using the service
- YouTube video URLs you add to projects.
- Project metadata: project names, descriptions, AI-generated topic labels, your pinned and archived choices.
- Questions you ask and the AI answers we generate in response.
- Display-title overrides, chat clear markers, and similar workspace preferences.
Automatically, as you use the service
- Transcript text we fetch from YouTube or generate via speech-to- text for each video you add. Cached so you can search and re- query without re-fetching.
- Usage counters: videos added, AI questions asked, projects created. Used to enforce plan limits and surface your usage on the Billing page.
- Standard server logs (IP address, user agent, request path) for security and debugging. Retained 30 days.
Billing information
We do not store payment card details. Stripe (PCI-DSS compliant) processes all payments. We only retain your Stripe customer ID and subscription status.
How we use your information
- Provide the service: index transcripts, generate AI answers, surface citations, render your workspace.
- Process payments and manage subscriptions via Stripe.
- Send transactional emails you've opted into (“video ready”, “video failed”), respond to support requests, and send important service notices.
- Aggregate, anonymized usage patterns help us understand which features are used and what to build next.
- Enforce plan limits and prevent abuse of the service.
We do not use your content to train AI models. The questions you ask and the videos you submit are not fed into LLM training pipelines — they're sent to the LLM as one-time queries with surrounding context and discarded by the provider after the response is generated.
Who we share your information with (sub-processors)
We use a small set of third-party sub-processors to operate the service. Each only receives the data they need for their specific job.
| Sub-processor | Purpose | Data shared |
|---|---|---|
| Clerk | Authentication, user accounts | Email, name, sign-in events |
| Supabase | Database hosting (US region) | All app data — projects, videos, transcripts, Q&A history |
| Vercel | Application hosting | Request data, server logs |
| Stripe | Payment processing | Email, billing info you enter at checkout (we never see card details) |
| OpenAI | Text embeddings for transcript search | Transcript chunks (no account-identifying info) |
| Anthropic | AI question answering | Your question + relevant transcript chunks |
| Inngest | Background job processing | Video-processing job metadata (videoId references) |
| Groq | Speech-to-text fallback when YouTube captions unavailable | Video audio streams (transient — not retained by Groq) |
| Google (YouTube Data API) | Video metadata fetching | YouTube video IDs |
| Resend | Transactional email delivery | Email address, notification content |
| Sentry (when enabled) | Error tracking | Stack traces, request context (PII redacted) |
We do not share your data with advertisers, data brokers, or any party not listed above.
Cookies
LaVoix uses essential cookies only — authentication session cookies set by Clerk to keep you signed in. We do not use advertising cookies, marketing trackers, or cross-site tracking pixels.
Data retention and deletion
We retain your data for as long as your account is active. You can delete your account at any time via Settings → Security → Delete account. When you delete your account:
- Your projects, videos, transcripts, and Q&A history are removed from our database within 30 days.
- Your Stripe customer record is retained as Stripe requires for tax / compliance, but no further charges are processed.
- Anonymized aggregate usage data may persist for service- improvement purposes.
You can also request a portable data export at any time by emailing support@lavoix.ai.
Your rights
Depending on your jurisdiction (e.g. GDPR, CCPA), you have the right to:
- Access the personal data we hold about you
- Correct inaccurate data (most can be done directly in your account settings)
- Delete your data (via account deletion or by request)
- Export your data in a portable format
- Object to certain processing
- Opt out of marketing communications (we send transactional emails only by default — there's no marketing list to opt out of)
To exercise any of these rights, email support@lavoix.ai. We respond within 30 days.
International data transfers
Our infrastructure is hosted in the United States (Supabase, Vercel). By using LaVoix.ai you consent to your data being processed in the US. We use sub-processors that comply with applicable data-transfer frameworks (Standard Contractual Clauses where required).
Security
We implement industry-standard security practices:
- Encryption in transit (TLS 1.2+) on all connections
- Encryption at rest for database storage (managed by Supabase)
- Access controls limiting who can query the production database
- Regular dependency updates for security patches
No security system is impenetrable. We can't guarantee absolute security, but we take reasonable measures and notify users promptly if we become aware of a security incident affecting their data.
Children
LaVoix.ai is not intended for users under 13 (or 16 in the EEA). We don't knowingly collect data from children below these ages. If you believe a child has provided us data, please contact support@lavoix.ai and we'll delete it.
Changes to this policy
We may update this policy as the service evolves. For material changes we'll notify you via email at least 30 days before the change takes effect. Continued use of the service after the change means you accept the updated policy.
