Cookie Policy · reviewed 1 October 2026
Browser storage supports the feature you choose.
The public site does not activate advertising or optional analytics trackers. The Laboratory caches public application files so its calculation engine can load reliably. An optional local walkthrough handover stores your selected calculation in the same tab only after your explicit choice. Financial values are not added to analytics or page URLs.
Storage inventory
Public application caching and a local calculation copy serve different purposes.
Cookies and similar technologies include browser caches and session storage. Server connection logs and the private enquiry queue are different from storage on your device.
| Technology | Purpose and content | Duration and removal |
|---|---|---|
| Laboratory service-worker cache | Public HTML, scripts, styles, calculation engine, catalogue and navigation assets. Calculation inputs and private records are excluded. | Until the public build replaces its cache or you clear site data. A new build removes the preceding named Lab caches. |
| Optional same-tab session storage | yieldguard.monitored-case.v1: a calculation request, receipt and model metadata copied only when you choose “Copy this calculation locally and continue”. The copy stays in your browser. | Valid for up to 30 minutes; expired copies are removed when accessed. The walkthrough clear control removes the copy earlier. Tab-session storage normally ends when the tab closes. |
| Browser's ordinary asset cache | Public site images, fonts and application files used for page delivery. | According to response/browser cache rules; remove through browser settings. |
| Advertising and optional analytics | Not activated by the current public site. | No current optional tracker setting is required to use the Laboratory. |
Your controls
You can clear the local calculation copy or all YieldGuard site data.
Use the walkthrough's clear control for the copied case. Your browser's site-data settings can remove caches and session storage for yieldguard.io. Removing caches can require another download of the calculation engine; clearing the local copy does not submit it to YieldGuard.
No optional-cookie preference banner is currently needed to choose advertising or analytics trackers because those trackers are not activated. If a later feature introduces non-essential storage or tracking, YieldGuard must provide the applicable information and consent or objection controls before activation. A general instruction to use the website is not consent for an undisclosed purpose.
