1. What Are Cookies and Local Storage Objects?
Cookies are compact alphanumeric text files downloaded to your computer or mobile device when you visit a website. They allow the server to distinguish your browser session, maintain security states, remember your visual preferences, and gather diagnostic performance metrics. Local storage (`localStorage`) provides similar key-value functionality stored client-side without transmitting data on every HTTP header request.
2. Cookie Classification Table
We categorize digital storage technologies into three distinct functional groups:
| Category | Identifier Name | Operational Purpose | Persistence Duration |
|---|---|---|---|
| Essential (Strictly Necessary) | `pp_cookie_consent` | Records your affirmative choice regarding cookie categories (accept/reject). | 12 Months (Local Storage) |
| Essential (Security) | `__cf_bm` / `XSRF-TOKEN` | Protects forms against cross-site request forgery and automated bot attacks. | Session / 30 Minutes |
| Functional | `pp_theme_pref` | Saves user display preferences and reduced-motion layout configurations. | 6 Months |
| Analytics (Aggregated) | `_pp_metric_id` | Aggregates anonymous reading depth and viewport dimension metrics. | 90 Days |
