Review edition - 26 October 2026
Who operates this service
Field Service Desk is operated by Jacobus Venter, 12 Goudrif Avenue, Allen Grove, Kempton Park, 1619, Gauteng, South Africa. Questions about cookies or device storage can be sent to prismage.visuals@gmail.com.
Why the service uses browser storage
Cookies support sign-in and security. Optional local job-card drafts use a separate browser database on a technician's device. Removing or blocking storage can affect sign-in, submission verification or unsent drafts.
Sign-in and security cookies
The following cookie families were observed during a signed-in browser check on 26 October 2026. Some names have an additional instance-specific suffix.
| Name | Domain observed | Purpose | Expiry observed |
|---|---|---|---|
| __session and suffixed variants | desk.prismage-visuals.com | Clerk sign-in credential | October 2027 |
| __client_uat and suffixed variants | .prismage-visuals.com | Clerk client/session freshness information | November 2027 |
| __client | .clerk.prismage-visuals.com | Clerk client authentication state | November 2027 |
| clerk_active_context | desk.prismage-visuals.com | Clerk active authentication context | Session |
| __cf_bm | .clerk.prismage-visuals.com | Cloudflare bot-management security | Time-limited |
| _cfuvid | .clerk.prismage-visuals.com | Cloudflare rate-limiting security | Session |
These expiry entries describe that browser check, not guaranteed storage periods. Providers can refresh cookies and browser settings can affect how long they remain. A cookie's expiry does not mean a sign-in remains valid until that date. Session cookies may also be affected by browser session restoration. Server-side account and log retention are separate from cookie expiry.
Public pages and appointment requests
The legal-document and public appointment pages do not initialise the application's Clerk sign-in provider. An available appointment request form loads Cloudflare Turnstile to verify submissions. Verification involves communication with Cloudflare. Depending on the provider configuration, security features may use additional browser storage. This review does not claim that every public-page flow is cookie-free.
For details about Turnstile processing, see https://www.cloudflare.com/privacypolicy/ . The service company's information on its appointment form explains how it uses the details submitted.
Optional local job-card drafts
A technician can enable local drafts on their device. The browser database field-service-device-drafts-v1 stores the account/company/profile scope, the local-draft preference, job identifier and number, work-note fields, an original-record digest, a retry identifier and an update time. The application does not store authentication secrets in this draft database.
Drafts remain until synced or cleared. Field-view sign-out clears the current scope's local drafts. Changing profile or losing server access does not remotely erase old copies on the device. Clearing browser site data can remove unsent work permanently, so sync needed drafts before clearing it. This feature supports drafts in an already loaded field view; it does not guarantee that the application can start or sign in without internet access.
Analytics and cookies from related websites
No direct advertising or analytics tracker was found in the reviewed application source. A fresh private-window visit directly to this service, followed by sign-in, showed no _ga cookies. A normal browser profile did contain _ga cookies on the parent domain .prismage-visuals.com. Parent-domain cookies can also be available to subdomains.
These observations do not identify which site originally set those cookies or exclude tracking without cookies. The separate Prismage Visuals website may have different technologies and choices. No optional tracking consent is obtained through this notice.
Your controls
Use your browser's site-data settings to inspect, block or remove cookies and local storage. Removing sign-in cookies may sign you out. Removing the draft database can delete unsent work. The application no longer writes the old sidebar_state preference cookie; a copy from an earlier visit may remain until expiry or removal.
There is currently no optional-cookie consent banner in this application. If optional tracking is introduced, this notice and the relevant controls must be updated before that tracking is enabled.
