1. What Are Cookies and Local Storage?
An HTTP cookie is a small text file transferred to your computer or mobile device when you visit a website. LocalStorage is an analogous web browser storage mechanism that allows lightweight key-value pairs to persist across browsing sessions without transmitting data back to the server in every HTTP request header.
2. Detailed Cookie & Storage Inventory
We believe in radical transparency. The table below documents every storage key, cookie identifier, lifecycle duration, and purpose deployed on this domain:
| Storage Key / Name | Category | Lifespan | Purpose & Description |
|---|---|---|---|
| jumbleo_cookie_consent_status | Strictly Essential (Storage) | 12 Months (localStorage) | Stores your preference choice ('accept', 'reject', or 'preferences') from the bottom cookie banner to prevent repeated banner prompts. |
| __cf_bm / __cfruid | Strictly Essential (Cookie) | 30 Minutes to Session | Assigned by European cloud delivery infrastructure to manage DDoS mitigation, rate-limiting, and bot detection on contact forms. |
| _jumbleo_anon_telemetry | Functional Analytics | Session only | Records non-personally identifiable page interaction timings to identify layout bottlenecks on mobile devices. Only activated if accepted. |
3. Granular Category Explanations
Strictly Essential Storage
Essential tokens and cookies are necessary for the basic technical operation and security of the website. Without these, core security features—such as preventing cross-site request forgery (CSRF) and remembering that you dismissed the cookie notice—cannot function. Under the ePrivacy Directive and GDPR, strictly essential storage does not require prior consent.
Functional & Telemetry Storage
These optional mechanisms measure how long readers engage with our technical guides (e.g. how many visitors scroll through our lighting photometrics or sub-base drainage modules). This telemetry is completely aggregated and contains no persistent user tracking IDs. If you select "Reject Non-Essential", these scripts remain entirely uninitialized.
