Cookie & Local Storage Policy

Effective date: March 2025

1. What Are Cookies and Local Storage?

Cookies are small text files that websites store on your device through your browser. They are commonly used to remember your preferences, keep you signed in, and track usage.

Local storage (localStorage) and session storage (sessionStorage) are browser-based storage mechanisms that allow websites to store data on your device. Unlike cookies, this data is not sent to the server with every request. Session storage is cleared when you close the browser tab; local storage persists until explicitly cleared.

gridmap primarily uses localStorage and sessionStorage rather than traditional cookies for its core functionality.

2. What We Use

localStorage

We use localStorage to store the following data on your device:

KeyPurposeDuration
auth-tokenKeeps you signed in to your accountUntil you sign out or clear browser data
sidebar-collapsedRemembers whether you prefer the sidebar open or collapsedUntil cleared
view-modeRemembers your preferred view mode (e.g., table vs. card view)Until cleared
themeRemembers your light or dark theme preferenceUntil cleared
cookie-consentRecords that you have acknowledged this policyUntil cleared

sessionStorage

We use sessionStorage for:

KeyPurposeDuration
sso-stateTemporary state used during SSO authentication flows (e.g., OAuth2 state parameter)Cleared when tab is closed

Essential Cookies

SvelteKit, the framework gridmap is built on, may set minimal technical cookies required for routing and server-side rendering. These are strictly necessary for the Service to function and do not track you.

3. What We Do NOT Use

gridmap does not use any of the following:

  • Tracking cookies — we do not track you across websites
  • Analytics cookies — we do not use Google Analytics, Mixpanel, or similar services
  • Advertising cookies — we do not serve ads or use ad-related tracking
  • Third-party cookies — no third-party services set cookies through gridmap

4. How to Manage Storage

You can manage or clear localStorage and sessionStorage through your browser's settings or developer tools:

  • Chrome: Settings > Privacy and security > Clear browsing data > Cookies and other site data (this also clears localStorage)
  • Firefox: Settings > Privacy & Security > Cookies and Site Data > Clear Data
  • Safari: Settings > Privacy > Manage Website Data
  • Edge: Settings > Privacy, search, and services > Clear browsing data

Note: Clearing localStorage will sign you out of gridmap and reset your preferences (sidebar state, view mode, theme). You will need to sign in again.

5. Changes to This Policy

We may update this Cookie & Local Storage Policy from time to time. When we make material changes, we will update the effective date at the top of this page and, where appropriate, notify you through the Service.
