Cookie Policy
Last updated: 2026-08-01
VigyanLLM is a sovereign biomedical AI platform. We minimise data collection and use analytics only with your consent. This policy explains the storage mechanisms used by our platform, how Google Analytics behaves, and your choices.
What We Use and Why
The VigyanLLM Primer tool uses browser localStorage and sessionStorage for essential application functions. Google Analytics 4 runs through our Google Tag Manager container under Google Consent Mode v2: it stays disabled until you accept in the EEA/UK/Switzerland, starts enabled elsewhere until you decline, and stays disabled everywhere if you decline.
| Storage Key | Type | Purpose |
|---|---|---|
pf_token | Cookie (HttpOnly, Secure, SameSite=Lax) | Authentication session token — stored in an HttpOnly cookie inaccessible to JavaScript, cleared on logout or after 7 days |
pf_design_history | localStorage | Stores your recent primer design results locally for history view |
pf_last_payment | sessionStorage | Temporary payment confirmation data during checkout flow |
pf_payment_error | sessionStorage | Temporary payment error details for user feedback |
pending_ref_code | sessionStorage | Referral code carried through sign-up flow |
acad_popup_shown | sessionStorage | Prevents repeated display of the academic discount prompt |
vigyanllm_cookie_consent | localStorage | Records your cookie-category choices (Accept All / Reject Optional / Manage Preferences); drives Google Consent Mode updates that gate analytics and marketing tags |
vigyanllm_consent | Cookie | Short-lived consent marker mirroring your banner choice |
Third-Party Services
The following third-party services may set their own cookies or storage when you interact with their components:
- Google Analytics 4 (property G-PB0XMF4GEH) — delivered by our Google Tag Manager container with Google Consent Mode v2 defaults. For visitors in the EEA/UK/Switzerland analytics storage stays denied until you click Accept All (or enable Analytics in Manage Preferences); other regions start enabled until you decline. It measures aggregate page usage and does not feed personalised advertising.
- Microsoft Clarity — session replay on some pages, loaded only after you enable the Analytics category
- Google OAuth 2.0 — when you sign in with Google, Google sets authentication cookies governed by Google's privacy policy
- Razorpay — when you complete a payment, Razorpay's hosted checkout may set session cookies necessary for payment processing
- Google Fonts — our pages load typefaces from Google Fonts; Google may log requests per its privacy policy
We do not control these third-party cookies. Please refer to the respective service's privacy policy for details.
Your Choices
When the consent banner appears, choose Accept All to enable Google Analytics or Reject Optional to keep it disabled. In the EEA/UK/Switzerland analytics is off by default until you accept; in all other regions it is on by default until you decline. You can change your choice by clearing the vigyanllm_cookie_consent item in your browser's site data, which will show the banner again on your next visit.
You can clear localStorage and sessionStorage at any time through your browser settings (typically Settings → Privacy & Security → Clear Site Data). Clearing this data will sign you out and remove your locally stored design history but will not affect your account on our servers.
Most browsers also provide private or incognito modes that clear sessionStorage automatically when you close the window.
Do Not Track
Our platform does not respond to Do Not Track (DNT) signals. Analytics behaviour is instead governed by your explicit Accept/Decline choice on the consent banner.
Updates
We may update this Cookie Policy from time to time. Changes will be posted on this page with an updated revision date.
