4.1 Service Providers
We use the following third-party providers to operate our services. Each acts as our processor under contract, handling data only on our instructions and only for the purposes below.
| Provider | Purpose | Data involved |
|---|---|---|
| OpenAI | Generates model responses in the demo and powers our hallucination analysis | The prompts and content you submit to the demo. Submitted via the OpenAI API, which is not used to train their models. |

| Vercel | Website and application hosting, aggregate analytics | Technical request data, server logs, and cookieless aggregate analytics |
| Stripe | Payment processing | Billing and payment details. Card numbers are handled by Stripe directly and never reach our servers. |

- With Your Consent: We may share information with your explicit consent.
5. Data Security
We implement appropriate technical and organizational security measures to protect your personal information against unauthorized access, alteration, disclosure, or destruction. However, no method of transmission over the internet or electronic storage is 100% secure, and we cannot guarantee absolute security.

To exercise these rights, please contact us at hello@telluvian.ai.
7. Cookies and Similar Technologies
We do not use advertising, profiling, or third-party tracking cookies, and we do not sell or share your data with advertisers. Because we set no non-essential cookies, we do not display a cookie consent banner. The storage we do use is described in full below.
7.1 Strictly Necessary Cookies
These cookies are required for the demo application to function and are exempt from consent requirements under UK PECR and EU ePrivacy rules. They are first-party only, are never read by third parties, and are set only when you visit the demo, the dashboard, or their APIs — not when you browse this marketing site.
| Name | Purpose | Duration |
|---|---|---|
sb-*-auth-token (anonymous session) |
Before you create an account, we sign you in anonymously so that the chats and analyses you create in the demo stay available to you. This is the same mechanism as a normal sign-in and stores no personal information — just a randomly generated account with no email address attached. If you later create an account, your email is added to that same anonymous account, so your existing work carries over automatically. | Session, with periodic refresh |
sb-*-auth-token (signed-in session) and related Supabase cookies |
Keeps you signed in to your account and maintains your authenticated session. Set by our authentication provider, Supabase, acting as our processor. Without these, signing in is not possible. | Session, with periodic refresh |
| Stripe cookies | Set by Stripe on its own checkout pages when you make a purchase, to process the payment and prevent fraud. These are set on Stripe's domain during checkout, not on ours. See Stripe's privacy policy for details. | Set and controlled by Stripe |
7.2 Analytics
We use Vercel Web Analytics and Vercel Speed Insights to understand aggregate traffic and page performance. Both are cookieless: they store no cookies and no identifiers on your device. Visitors are counted using a temporary hash derived from the incoming request, which is discarded within 24 hours and cannot be used to follow you across sites or to re-identify you. We collect only aggregated data such as page URL, referrer, approximate location derived from IP address (country, region, city — the IP address itself is not stored by us), device type, operating system, browser, and page performance measurements.
We configure analytics to strip query strings and to replace identifiers for individual chats and analyses with the general page pattern before any data is transmitted. This means the content of your prompts and the identity of the specific chats or analyses you view are not sent to our analytics provider.
7.3 Browser Storage
The demo uses your browser's localStorage and sessionStorage to hold unsent message drafts, your sidebar and display preferences, and scroll positions, so your work is not lost if you navigate away or reload. This information stays in your browser, is never transmitted to us, and can be cleared at any time through your browser settings.
7.4 Your Choices
You can block or delete cookies through your browser settings. Because the cookies we set are strictly necessary, blocking them will prevent sign-in and cause the demo to stop working correctly; the marketing pages will continue to function normally.
8. Third-Party Links
Our website may contain links to third-party websites. We are not responsible for the privacy practices or content of these external sites. We encourage you to review the privacy policies of any third-party sites you visit.
9. Children's Privacy
Our services are not intended for individuals under the age of 18. We do not knowingly collect personal information from children. If you believe we have collected information from a child, please contact us immediately.
10. International Data Transfers
Your information may be transferred to and processed in countries other than your country of residence. These countries may have data protection laws that differ from those in your country. By using our services, you consent to such transfers.
11. Changes to This Privacy Policy
We may update this Privacy Policy from time to time. We will notify you of any material changes by posting the new policy on this page and updating the "Last updated" date. Your continued use of our services after such changes constitutes acceptance of the updated policy.
