Cookie Policy

A cookie is a small text file a website stores in your browser so it can recognize you on the next page or the next visit. CourseDuck uses a handful of its own and a few from Google and Meta. This page lists all of them. We do not use a cookie banner: the site works without your accepting anything, and the advertising and analytics cookies can be switched off with one click on the Do Not Sell or Share My Personal Information page.

Cookies we set ourselves

These come from courseduck.com and are only read by us.

Cookie	What it does	Lasts
subidCookie	Links your visit to the page you arrived on and any campaign tags in the address (utm_*, gclid), so we can see which campaigns bring people here. Your IP address is stored with it. Nobody outside CourseDuck receives it.	24 hours
cd_privacy_optout	Remembers that you opted out of sale or sharing on the Do Not Sell page, so the Google and Meta tags stay off. Only set if you use that page.	13 months
wordpress_test_cookie	Checks that your browser accepts cookies when you sign in. Contains no personal data.	Session
wordpress_logged_in_* wordpress_sec_*	Keep you signed in to your CourseDuck account. Only set if you sign in.	Session, or 14 days with "Remember me"
wp-settings-*	Remember your screen preferences when signed in.	1 year
comment_author_*	Only if you leave a comment on a blog post and tick "save my details": fills in your name, email and website next time.	1 year

Cookies set by other companies

These are set by tags we load on every page. They let Google and Meta recognize your browser across the websites that use their tools, which is why California law may count them as "sharing" personal information. Opt out on the Do Not Sell page and none of them are set.

Cookie	Set by	What it does	Lasts
_ga _ga_*	Google Analytics	Tell visitors and visits apart so we can count how many people use the site and which pages they read.	Up to 2 years
_gid	Google Analytics	Same purpose, for the current day.	24 hours
_gat_*	Google Analytics	Limits how often data is sent to Google.	1 minute
_fbp	Meta (Facebook Pixel)	Identifies your browser to Meta so visits can be matched to our Facebook and Instagram ads, and can be used by Meta for advertising profiles.	90 days

Google Analytics' advertising features also contact doubleclick.net, where Google may set its own cookies in some browsers. Their policies: Google and Meta.

Embedded content

The contact page embeds a Google Map, courses hosted on YouTube are embedded on their course page, and the "Watch preview" button on some course pages opens a YouTube or Vimeo video. YouTube embeds use YouTube's privacy-enhanced mode, which sets no cookies until you press play. Once an embed loads or plays it behaves as if you had visited that site, under its own privacy policy.

How to say no

• One click: the Do Not Sell or Share My Personal Information page switches off Google Analytics and the Facebook Pixel for your browser and deletes the cookies they already set.
• Automatically: if your browser sends the Global Privacy Control signal (Brave, Firefox and DuckDuckGo can), we treat it as an opt-out on every visit.
• In your browser: every browser lets you block or delete cookies for a single site or all of them; look under Settings, Privacy. Blocking our own cookies means you cannot stay signed in.
• With Google and Meta directly: Google's opt-out browser add-on stops Google Analytics on every site, and Meta's ad settings let you turn off ads based on data from other websites.

Changes

If we add or remove a cookie we update this page and the date below. Questions: mkuhlman12@gmail.com.
