Short version: we use essential session cookies to keep you signed in. We use Google Analytics to understand how the site is being used, but only after you consent via our cookie banner. No advertising cookies, no tracking for marketing purposes.
This Cookie Policy explains how 18December uses cookies and similar tracking technologies on this Platform. It should be read alongside our Privacy Policy.
Cookies are small text files placed on your device when you visit a website. They help websites function, remember your preferences, and provide information to site operators about how their site is used. Similar technologies include local storage and session storage.
These cookies are necessary for the Platform to function. Without them, you cannot sign in or use core features. Essential cookies cannot be disabled.
We use your browser's local storage (not cookies) to save your onboarding pathway selection, your checklist state, and which guides you have read or saved. If you are not signed in, this data remains on your device and is not transmitted to our servers. If you are signed in, this state is also saved to your account so it is available across your devices. Functional storage is necessary for these features to work and is not used for analytics or marketing.
We use Google Analytics 4 to understand how visitors use the Platform. Google Analytics collects anonymised data including pages visited, session duration, approximate geographic region, device type, and browser. This data is aggregated and used to improve the Platform. Analytics cookies are non-essential and are only placed after you give your consent via our cookie banner.
You may withdraw consent at any time by clicking the cookie preferences link in the footer. You can also opt out by installing the Google Analytics Opt-out Browser Add-on. Google Analytics data is processed by Google in the United States under Standard Contractual Clauses.
We do not use marketing or advertising cookies. We do not serve targeted advertising on this Platform.
Some cookies on this Platform are set by third-party services we use:
These providers set and read cookies in accordance with their own privacy policies. We do not control third-party cookies.
When you first visit the Platform, a cookie consent banner allows you to accept or decline non-essential cookies. You can update your preferences at any time by clicking the cookie preferences link in the site footer.
You can also manage or delete cookies through your browser settings at any time. Most browsers allow you to view, delete, or block cookies from specific sites or entirely.
Please note that disabling essential cookies (including Clerk session cookies) will prevent you from signing in to the Platform. Disabling analytics cookies will not affect your ability to use any Platform features.
Browser-specific instructions:
We do not currently respond to browser-level “Do Not Track” signals, as there is no industry-wide standard for these signals.
We do honour Global Privacy Control (GPC) browser signals. If your browser sends a GPC signal, we treat it as a request not to share your data for targeted advertising purposes. As we do not use advertising cookies, this has no practical effect on most users at this time.
We may update this Cookie Policy from time to time. Material changes will be communicated via the Privacy Policy update process. The date at the top of this page indicates when it was last updated.
For questions about our use of cookies, contact us at hello@18december.com.au.
18December does not sell, rent, or share your personal information with third parties for advertising or marketing purposes. We do not engage in cross-context behavioural advertising. The data we share with service providers (listed in our Privacy Policy) is solely to operate the platform, not for commercial data transactions.
