1. What Are Cookies & Local Storage?
Cookies are small text files placed on your device by a web browser when you visit a website. Along with browser local storage and session tokens, they enable web applications to remember your session state, authenticate API requests, and preserve your customized dashboard preferences.
2. Cookie Categories We Use
Quiver utilizes minimal, privacy-centric cookies categorized as follows:
- Strictly Necessary / Essential Cookies: Indispensable for the platform to function. They authenticate your identity, prevent CSRF attacks, protect against unauthorized session hijacking, and manage RBAC permissions. These cannot be disabled in our systems.
- Functional & Preference Cookies: Remember your interface preferences, such as Dark Mode / Light Mode theme, preferred proposal tone, active model provider selector, and collapsible sidebar state.
- Performance & Telemetry Cookies: Anonymously measure API response times, latency, and error rates to maintain our platform reliability SLAs.
