Cookie Policy
Effective date: September 9, 2026
This Cookie Policy explains which trackers the website at primegraph.ai and the PrimeGraph application (together, the “Service”) use, and how you can manage them. It forms part of the Privacy Policy, where the Owner and Data Controller, PrimeGraph, Inc., is identified.
1. What trackers are
A “tracker” is any technology that lets the Service store or read information on your device, such as cookies, local storage, session storage, and unique identifiers. Trackers can be set by the Owner (first-party) or by a third party providing a service to the Owner (third-party). Some trackers are necessary for the Service to work; others are optional and are used only with your consent.
2. Trackers used by the Service
Strictly necessary
These trackers are required to deliver the Service and to remember your choices. They do not require consent.
| Tracker | Provider | Purpose | Duration |
|---|---|---|---|
| Firebase Authentication session (IndexedDB, local storage) | Google LLC, first-party | Keeps you signed in to the application | Until sign-out |
pg-cookie-consent (local storage) | PrimeGraph, first-party | Remembers whether you allowed or denied optional trackers | Until you clear site data |
| Interface preferences (local storage) | PrimeGraph, first-party | Remembers editor and layout settings in the application | Until you clear site data |
| Hosting and security cookies | Google LLC (Firebase Hosting, Cloud Run) | Load balancing and protection against abuse | Session |
Optional
At the effective date of this policy the Service sets no optional trackers: there are no analytics, advertising, or social-media trackers. Should the Owner add optional trackers, such as analytics, they will be listed here with their provider and purpose, and they will be set only after you choose Allow in the cookie banner.
3. How to manage your preferences
- Cookie banner: on your first visit the Service shows a banner with Allow and Deny. Your choice is stored on your device. To change it, clear the site data for primegraph.ai in your browser; the banner will appear again.
- Browser settings: you can block or delete cookies and site data in your browser. Note that blocking strictly necessary trackers prevents you from staying signed in to the application. Instructions for common browsers: Chrome , Firefox , Safari , Edge .
- Third-party trackers: trackers set by third parties can also be managed through the provider’s own opt-out tools, linked from the provider’s privacy policy.
4. Owner and Data Controller
