Cookie policy
Last updated: 21 October 2026 · E-Smart Solutions Limited
1. What this policy covers
This policy explains storage and external resources used by the 4-Sight website, operated by E-Smart Solutions Limited. Cookies and similar browser technologies may hold information needed for access or website functions. Our privacy policy explains related personal information.
2. Website code and referrals
The website’s own code does not set analytics, advertising, marketing or referral cookies. It does not use localStorage or sessionStorage to retain referral codes. Referral attribution travels in the URL as a ref parameter when you navigate or follow a link into the app. It is not persistent browser tracking, although the URL can appear in browser history and server logs.
3. Hosting and sign-in
This Namesco-hosted website uses a necessary cookie named FOUR_SIGHT_SESSION for sign-in and request security. It contains an opaque session identifier, is restricted to this website, is sent over HTTPS and cannot be read by JavaScript. It is a browser-session cookie; the server expires access after 30 minutes of inactivity or 12 hours overall. Sign-out invalidates the session. Our hosting provider may maintain additional infrastructure security records or cookies; confirm any provider-added cookies against the live hosting configuration. No ChatGPT sign-in is used by this website.
4. Fonts, scripts and media
DM Sans and Manrope font files are served directly from this website in WOFF2 format. The website does not request its fonts from Google. Menu, calculator, product-tour, referral, partner and administration scripts are served locally. Screenshots are local image files; there are no embedded YouTube videos, Google Analytics tags, advertising pixels or chat widgets in the website code.
5. Choices
You can review, block or remove cookies using your browser’s settings. Blocking authentication or security cookies may prevent sign-in or restricted pages from working. No analytics or advertising consent panel is needed to enable the current local scripts and fonts. If optional tracking is introduced, this policy and the consent controls will be updated before it is enabled where consent is required.
6. The separate app and updates
Following an app link takes you to app.4-sight.com. Its Xero sign-in, billing and storage are governed by the information provided there; this notice is not a cookie inventory for that separate application. We will update this page if the marketing website’s technology changes. Contact details are in our privacy policy.
