Cookie Policy
Effective Date: June 15, 2026 Last Updated: June 15, 2026
This Cookie Policy explains how Sarvabhaum AI ("we," "us," or "our") uses cookies and similar technologies on Tensor (https://sarvabhaum.ai).
1. What Are Cookies?
Cookies are small text files that a website places on your browser when you visit. They are widely used to make websites work, remember your preferences, and provide information to site owners.
2. Cookies We Use
Tensor uses one cookie, and it is strictly necessary to operate the service:
| Cookie name | Type | Purpose | Duration |
|---|---|---|---|
tensor_refresh | HttpOnly, Secure, SameSite=Lax | Stores your authentication refresh token so you remain logged in across browser sessions | 7 days from last login |
Why this cookie is necessary
Without this cookie, you would be logged out every time you close your browser tab or navigate away from Tensor. It is technically essential to the service and cannot be disabled without breaking authentication entirely.
This cookie does not track you across other websites. It is scoped to sarvabhaum.ai only and is never shared with third parties.
What "HttpOnly, Secure, SameSite=Lax" means
- HttpOnly — JavaScript in the browser cannot read this cookie, protecting it from cross-site scripting attacks
- Secure — the cookie is only sent over HTTPS connections, never plain HTTP
- SameSite=Lax — the cookie is not sent with cross-site requests initiated by third-party websites, protecting against cross-site request forgery
3. What We Do Not Use
We do not use:
- Advertising or marketing cookies — we do not run ad campaigns or retarget users
- Cross-site tracking cookies — we do not share cookie data with advertising networks
- Third-party analytics cookies — our analytics tool (Umami) is cookieless (see §5)
- Social media cookies — there are no embedded social widgets or share buttons
4. Browser Local Storage (Not Cookies)
We also store a small amount of data in your browser's localStorage. This is distinct from cookies — it is never transmitted to our servers and is used only for your local interface preferences:
| Key | Purpose |
|---|---|
| Theme preference | Remembers whether you prefer dark or light mode |
| Onboarding completion | Remembers whether you have completed the welcome steps |
| AI disclosure acknowledgement | Records that you have seen the first-session AI chatbot notice |
| UI panel preferences | Remembers which panels are open or closed |
None of this data contains personally identifiable information and none of it leaves your browser.
5. Analytics — Umami (Cookieless)
We use Umami Analytics, a privacy-first, open-source analytics tool that we host on our own servers. Umami:
- Sets no cookies of any kind
- Collects only anonymised page view counts and navigation events
- Does not track individual users across sessions
- Does not share any data with third-party analytics companies
- Respects the Do Not Track (DNT) browser signal — if DNT is enabled in your browser, Umami will not record your visit
- Stores all data on our own servers; nothing is sent to Umami Inc.
Because Umami is cookieless and collects no personal data, no cookie consent is required for our analytics.
6. How to Manage Cookies
Browser settings
You can control cookies through your browser settings:
- Chrome — Settings → Privacy and security → Cookies and other site data
- Firefox — Settings → Privacy & Security → Cookies and Site Data
- Safari — Preferences → Privacy → Manage Website Data
- Edge — Settings → Cookies and site permissions
Note that blocking the tensor_refresh authentication cookie will prevent you from staying logged in to Tensor.
Clearing local storage
To clear localStorage data set by Tensor, you can use your browser's developer tools (Application → Storage → Local Storage) or clear all site data in your browser's privacy settings.
7. Changes to This Policy
We will update this policy if we change how we use cookies. Material changes will be notified by email at least 30 days before taking effect. The current policy is always available at https://sarvabhaum.ai/cookies.
