2. What Are Cookies?
Cookies are small text files stored on your device when you visit a website. They help websites remember your preferences, improve performance, and provide analytics. This Website uses analytics cookies only after you have given your consent via the cookie banner.
3. Cookies I Use
3.1 Essential Site Storage
The following items are necessary for the Website to function. They are stored as browser localStorage entries (not HTTP cookies), but serve similar purposes:
| Name | Purpose | Duration |
|---|---|---|
theme | Stores your light/dark theme preference | Persistent (until cleared) |
cookie-consent | Stores your cookie consent choice | Persistent (until cleared) |
3.2 Analytics Cookies (Google Analytics 4)
When you accept analytics cookies, I use Google Analytics 4 (GA4) to understand how visitors use the Website. GA4 sets the following first-party cookies:
| Cookie Name | Purpose | Duration |
|---|---|---|
_ga | Analytics: Used to distinguish unique users and calculate visitor, session, and campaign data for the site's analytics reports. | 2 years |
_ga_* | Analytics: Used to persist session state and maintain session status (e.g. _ga_G-LKHDQT8Z81) | 2 years |
Note: Browsers may limit cookie lifespan. Chrome caps first-party cookies at approximately 400 days without a return visit; Safari may limit to 7 days. See Google's GA4 cookie documentation for details.
4. Managing Cookies
You can control cookies in several ways:
- Cookie banner: When you first visit, you can accept or reject analytics cookies.
- Browser settings: Most browsers let you view, delete, or block cookies. Check your browser's help section for instructions.
- Google Analytics opt-out: Install the Google Analytics Opt-out Browser Add-on to prevent Google Analytics from collecting data across websites.
Blocking or deleting cookies may affect the functionality of some parts of the Website.
