Who We Are

AI Cert Guides is an independent educational resource for people preparing for AI certification exams, run by Lets Learn More AB. It is not affiliated with, endorsed by, or sponsored by Anthropic, OpenAI, Gemini, SpaceXSI or Mistral.

What Data We Collect

We collect minimal data to understand how the site is used and to improve the learning experience:

• Analytics data — We use Google Analytics (GA4) and Vercel Analytics to collect anonymous usage data including page views, session duration, device type, browser, and approximate geographic location. We also record when a mock exam or diagnostic is completed, along with the score, which certification it was for, how long a diagnostic took and, for a mock exam, its length and whether it was a pass, so we can see how many people finish an assessment. No personally identifiable information is collected by these tools: a completion event carries no name, no email address and nothing you typed.
• Account data — If you create an account, we store your email address, username, display name, how you sign in (password, Google, Microsoft, LinkedIn, GitHub or Apple), the profile fields you fill in, and the study progress saved from your browser: lessons completed, mock exam and diagnostic scores, and drill progress. For mock exams, drill and the diagnostic we also keep every answer you give, whether it was right and how long you spent on each question. We look at these across all learners to find questions that are too hard, too easy or unclear, and fix them. Weekly totals per question, with no account attached, stay after an account is deleted. The mock exam review also shows how everyone answered each question, as totals with no account attached.
• Diagnostic answers — You can take the free diagnostic signed out. We still keep each answer, whether it was right and how long you spent on it. Nothing we keep carries your name, your email address or an ID that links one round to another. Signed in or out, we also note whether you had seen the question before. Your browser, or your account when you are signed in, keeps a list of questions you have seen, so each round asks new ones.
• Product usage while signed in — While you are signed in, we record a few milestones against your account: when you finish setting up your account, see the page offering a mock exam pack (and which link took you there), start, return from or complete a checkout, start or finish a diagnostic or a mock exam, open the drill, open a lesson, open how everyone answered a question in a mock exam review, visit your dashboard or switch between its certifications, and click a certification, a question in the FAQ or one of the main links on the home page. Each record holds the milestone, the certification, the time, your account's internal id and a short detail such as which lesson or which mock exam it was, or your score; never your name or email address. We also keep these facts about the account: when and how you signed up (by email or with Google, for example), where you signed up from, whether you took the free diagnostic first, your answer to “Can you sit a Claude exam yet?”, the certification you chose, whether you have bought a pack and, if you have, when you first bought and which pack. Our server sends all of this to PostHog, which stores it for us in the EU. We use it to see where people get stuck and to improve the service. Apart from the milestones above, the pages you visit are not recorded. Nothing is stored in your browser for these records, and nothing is recorded while you are signed out.
• Purchase data — When you buy access, Dodo Payments handles the payment and your card details; we never see them. We receive and keep the payment reference, the amount and currency, the email address you bought with, which certification you bought and when you ticked the box at checkout asking for access to start straight away, so we can give you access and handle refunds.
• Feedback submissions — If you use the feedback button, any text you submit is collected to improve the site. Do not include personal information in feedback messages.

Cookies and Tracking

Google Analytics uses cookies to distinguish unique users and sessions. These are first-party cookies set by Google's analytics script. Vercel Analytics does not use cookies. We do not use any advertising cookies or tracking pixels.

If you visit from the EU, the EEA, the UK or Switzerland, Google Analytics sets no cookies until you accept them in the banner, and you can change your choice at any time from “Cookie settings” in the footer. To know whether to show that banner, the site sets a short-lived cookie holding only your country code.

Signing in sets session cookies that keep you signed in. They are needed for your account to work and are not used for tracking.

How We Use Your Data

• To understand which content is most useful and where users spend time
• To identify technical issues (broken pages, slow load times)
• To improve lessons, practice questions, and study materials
• To run your account, give you access to what you bought, and send the emails an account needs, such as confirming your address or resetting your password
• To email you exam tips, data insights and exam guide updates if you said yes when you set up your account; you can unsubscribe at any time or turn them off in your account settings

We do not sell, share, or transfer your data to third parties for marketing or advertising purposes.

Your Rights

If you have an account, you can delete it from your profile page. That removes your account, your saved progress and your access records from our database, and asks PostHog to delete the usage milestones recorded against it. Dodo Payments keeps its own record of any purchase for as long as tax law requires.
