Cookie Policy
Last updated: July 2026
What are cookies?
Cookies are small text files placed on your device when you visit a website. They are widely used to make websites work efficiently and to provide information to the site owner. We give you a choice about every cookie that is not strictly necessary, and we do not set analytics or advertising cookies until you allow them.
Cookies we use
Authentication
When you log in via the magic link we email you, we set a session cookie to keep you signed in as you navigate between pages. Without this cookie the site cannot function for logged-in users.
| Cookie | Purpose | Duration |
|---|---|---|
| dd_session | Keeps you logged in | Session / 1 week |
Consent required: No — these are strictly necessary.
Google Analytics 4
We use Google Analytics to understand how visitors find and use the site — for example, which pages are most visited and how long people spend on them. This helps us improve the platform. Data is sent to Google and is processed on Google's servers in the United States.
| Cookie | Purpose | Duration |
|---|---|---|
| _ga | Distinguishes unique users | 2 years |
| _ga_* | Session state | 2 years |
| _gid | Distinguishes users (short-term) | 24 hours |
Consent required: Yes — non-essential analytical cookie.
Google Ads
We use Google Ads to run search campaigns. Google sets a cookie to measure whether someone clicked one of our ads before visiting the site, so we can understand which campaigns are working. Data is processed on Google's servers in the United States.
| Cookie | Purpose | Duration |
|---|---|---|
| _gcl_au | Ad conversion tracking | 90 days |
Consent required: Yes — non-essential advertising cookie.
Vercel Analytics
Our hosting provider Vercel collects aggregated, anonymous page-view data to help us monitor site performance. Vercel Analytics does not set any cookies and does not collect personal data or IP addresses.
Consent required: No — no cookies set, no personal data collected.
How to manage cookies
You have several options to control non-essential cookies:
- ▸Browser settings — all modern browsers let you block or delete cookies. Visit your browser's help section for instructions (Chrome, Firefox, Safari, Edge).
- ▸Google opt-out — install the Google Analytics Opt-out Browser Add-on to prevent Google Analytics from tracking your visits.
- ▸Ad personalization — manage your Google ad settings at adssettings.google.com.
Blocking essential cookies will prevent login from working. Blocking analytics and advertising cookies will not affect your ability to use the practice modules.
