Cookie Notice
Last Updated: April 3, 2026 Effective Date: March 26, 2026
This Cookie Notice explains what cookies are, which cookies this site uses, and how you can manage them.
What Are Cookies?
Cookies are small text files placed on your device when you visit a website. They allow the site to recognize your device on subsequent visits, remember your preferences, and collect data about how you use the site.
Cookies are not programs. They cannot carry viruses or install software. They are data files — nothing more.
In addition to traditional cookies, this site uses similar technologies including local storage. This notice covers all of them.
Your Cookie Choices
When you first visit this site, you will see a cookie consent banner. You can accept or decline non-essential cookies from that banner.
Strictly necessary cookies are always active — they are required for the site to function and cannot be switched off.
Analytics and marketing cookies are optional. You can withdraw your consent at any time by clearing your browser cookies and revisiting the site, which will present the consent banner again.

Marketing
These cookies are used to show relevant advertisements to previous visitors on other websites (remarketing). They are set by third-party advertising platforms, not directly by this site. These cookies are set only if you consent.
We may use the following advertising platforms. When active, they set their own cookies:
Google Ads — Measures ad conversion and supports remarketing. Manage your settings at adssettings.google.com.
Facebook/Meta Pixel — Supports remarketing to Facebook and Instagram users, if active.
LinkedIn Insight Tag — Supports remarketing to LinkedIn users, if active.
Not all of these platforms may be active at any given time. Marketing cookies are only set when both (a) you have consented and (b) the platform is enabled on this site.

Resource | Provider | Purpose |
|---|---|---|
Web fonts (Inter, Manrope, Space Mono, PT Mono) | Google Fonts | Typography |
Icons (Font Awesome 6.5.1) | Cloudflare CDN | Icon library |
These services may log requests (including your IP address) per their own privacy policies. They do not set cookies on your device.
Managing Cookies in Your Browser
You can control cookies at the browser level:
Note: Blocking all cookies will affect site functionality. Strictly necessary cookies are required for the site to work correctly. If you block them, some features may not behave as expected.
Do Not Track
Some browsers send a "Do Not Track" signal. This site does not currently respond to Do Not Track signals. If that changes, this notice will be updated.
