Cookie Policy

We keep our cookie usage minimal. Here's exactly what we set and why.

Last updated: 8 April 2026

This Cookie Policy explains how Pulspective uses cookies and similar technologies on our website and platform. We have deliberately kept our cookie footprint as small as possible. We use only what is strictly necessary to make the Service function.

1. What Are Cookies?

Cookies are small text files stored on your device by your browser when you visit a website. They allow the website to recognise your device and remember certain information across page loads or sessions.

2. Cookies We Use

We set two cookies: one for manager authentication and one for anonymous nurse device identity. Both are strictly necessary for the Service to function.

Manager authentication cookie

sb-[project-ref]-auth-token

ProviderSupabasePurposeStores the manager's authenticated session so they remain logged in across page loadsSet onManager-facing pages only (/manager/*)DurationSession (expires when the browser is closed, or after inactivity)TypeHttpOnly, Secure, SameSite=Lax

Nurse device identity cookie

pulspective_device_uuid

ProviderPulspectivePurposeStores a randomly generated pseudonymous device identifier created when a nurse first joins a ward. Used for rate-limiting daily check-ins and recovering check-in history if browser storage is cleared. Never associated with a name, email, or any other identifying information.Set onNurse-facing pages (/nurse/*, /join)Duration2 yearsTypeSameSite=Lax (client-accessible)

Analytics and advertising cookies

We do not use any analytics, tracking, advertising, or third-party cookies. We do not use Google Analytics, Meta Pixel, or any similar service.

3. localStorage Usage

In addition to the cookie above, we store the following in your browser's localStorage on nurse-facing pages:

  • The ward group ID the device is associated with (set during QR code onboarding)
  • Local check-in history and concern records (stored on-device for the nurse's own reference)

This data never leaves your device except when submitting a check-in or concern report, at which point it is transmitted over an encrypted connection and stored pseudonymously. You can clear all of this data at any time by clearing your browser's site data for this domain.

4. Do We Require Cookie Consent?

Because we use only strictly necessary cookies, and no cookies are set for analytics, advertising, or profiling, we do not display a cookie consent banner. This is consistent with the guidance issued by Singapore's Personal Data Protection Commission (PDPC) and widely accepted practice in Singapore.

5. How to Manage or Delete Cookies

You can control and delete cookies through your browser settings. Please note that disabling the authentication cookie will prevent manager accounts from functioning. Below are links to cookie management guides for common browsers:

  • Google Chrome: Settings > Privacy and security > Cookies and other site data
  • Safari: Preferences > Privacy > Manage Website Data
  • Mozilla Firefox: Options > Privacy & Security > Cookies and Site Data
  • Microsoft Edge: Settings > Cookies and site permissions

6. Changes to This Policy

If we introduce new cookies (for example, analytics tools added in a future version), we will update this Cookie Policy and, where required, implement a consent mechanism before setting those cookies.
