Qbix Systems strictly limits tracking technologies. We do not use third-party behavioral advertising cookies or sell browsing telemetry. Our cookies exist primarily to maintain encrypted enterprise sessions, defend against DDoS attacks, and remember your language preferences.
1. What Are Cookies & Storage Technologies?
Cookies are small cryptographic text files placed on your device (computer, smartphone, or tablet) by websites you visit. They are widely used to ensure websites function securely and efficiently, as well as to provide reporting data to site operators.
Alongside cookies, modern web applications utilize web storage technologies such as localStorage and sessionStorage. In this policy, we use the term "Cookies" collectively to refer to cookies, web storage, and session identifiers.
2. Why We Use Cookies
We deploy cookies and web storage for four core operational requirements:
- Session Authentication: Keeping authenticated enterprise users, partner affiliates, and school administrators securely logged into their respective dashboards.
- Infrastructure Defense: Distinguishing legitimate browser requests from malicious botnets, brute-force credential stuffing, and DDoS attacks via Cloudflare.
- User Experience & Localization: Remembering user interface settings, such as preferred language (English or Bengali) and theme state.
- System Reliability: Measuring edge delivery speed and page rendering latency to diagnose software bugs and maintain our 99.9% uptime SLA.
3. Granular Cookie Categories
We categorize cookies into distinct tiers based on operational necessity:
These cookies are strictly required for our platforms to operate securely. They include cryptographically sealed Iron Session cookies for authenticated sessions, CSRF mitigation tokens, and Cloudflare security verification tokens. Without these, secure access cannot be provided.
These cookies enable enhanced personalization by remembering your choices, such as selected language (locale=en or locale=bn), collapsed sidebar status in portals, and cookie banner consent status.
Aggregated and anonymized performance telemetry that tracks Core Web Vitals (Largest Contentful Paint, First Input Delay, Cumulative Layout Shift). No personally identifiable information (PII) is linked to these metrics.
Used solely to attribute commercial sales and inquiries to registered Qbix partner referral links (e.g., qbix_ref=partner_id). This is strictly first-party attribution and is not shared with ad networks.
4. Cookie Lifespan & Retention Schedule
Cookies deployed on Qbix Systems platforms are governed by strict retention schedules and are classified into two operational lifecycles:
Temporary tokens that remain in your browser's memory only for the duration of your browsing session. They are automatically deleted when you close your browser tab or log out. We use these for secure authentication state and navigation continuity.
Stored on your device for a pre-determined duration (ranging from 30 minutes for edge security tokens up to 12 months for language preferences) or until manually cleared. They allow our platform to recognize your preferences on subsequent visits.
Below is a summary of our cookie categories, operational purposes, and retention lifespans:
| Category | Operational Purpose | Lifespan | Classification |
|---|---|---|---|
| Essential Security & Auth | Maintains encrypted user sessions, defends against DDoS/bot attacks, and mitigates CSRF threats. | Session to 7 days | Strictly Required |
| Preferences & Localization | Remembers selected language (English / Bengali) and UI interface customization. | 6 months to 1 year | Functional |
| Performance Telemetry | Anonymously measures edge delivery speed, server response times, and Core Web Vitals (zero PII). | Session to 30 days | Analytics |
| Partner Referral Attribution | First-party attribution to credit commercial referrals from authorized partner campaigns. | 30 days | First-Party |
5. Local Storage & Session Storage
In addition to cookies, our browser clients utilize HTML5 localStorage to store non-sensitive state, such as drafted inquiry inputs (to prevent data loss if a tab is accidentally closed) and UI toggle preferences. This data remains on your physical device and is not automatically transmitted in HTTP request headers.
6. Third-Party Telemetry & CDNs
Qbix utilizes global Content Delivery Networks (primarily Cloudflare) to ensure lightning-fast global asset delivery and edge security. These infrastructure partners process technical telemetry (such as connection round-trip times and TLS handshake parameters) strictly to deliver web content securely and optimize routing pathways.
7. How to Control & Disable Cookies
You have the right to decide whether to accept or reject cookies. You can exercise your cookie preferences by modifying your browser settings:
- Google Chrome: Settings → Privacy and Security → Third-party cookies.
- Apple Safari: Preferences → Privacy → Block all cookies.
- Mozilla Firefox: Settings → Privacy & Security → Enhanced Tracking Protection.
- Microsoft Edge: Settings → Cookies and site permissions → Manage and delete cookies and site data.
Please Note: If you choose to block strictly necessary cookies, key security-protected areas of our website (including partner dashboards and administrative portals) may become inaccessible or fail to function properly.
8. Do Not Track & Global Privacy Control (GPC)
We honor modern browser privacy signals, including Global Privacy Control (GPC) and Do Not Track (DNT). Because Qbix does not participate in cross-site tracking or third-party advertising exchanges, our platforms natively operate in compliance with these signals.
9. Policy Updates & Legal Contact
We review this Cookie Policy periodically to reflect changes in our technology or applicable legal requirements. Revisions will be published on this page with an updated revision date.
