How I handle your information

What NDTPrep collects, why it is collected, who it is shared with, and what control you have over it. It covers this site and every course sold through it.
Last updated: September 2026
Who I am

NDTPrep.com is run by Sean Fraenkel, a sole proprietor trading as NDTPrep, based in South Africa. I am the sole owner and operator of this site.

If you have any question about this policy, or about your information, email me at support@ndtprep.com.

What I collect
Information Why
Your name and email address To create your student account, give you course access, and send you the emails you asked for
Purchase records To confirm what you bought, give you access for the right period, and handle refunds
Course progress and quiz results To save your place, track your progress, and show you where you are weak
Technical data, such as browser, device and general location To keep the site working, and to see which pages are useful

I never see your card details. Payments are handled by my payment provider. Your card number never reaches NDTPrep and is never stored by me.

Who I share it with

I do not sell your information. I do not trade it. I share it only with the services needed to run NDTPrep, and only as far as they need it.

Service What it does
Thinkific Hosts the website and the courses, and holds your student account
Creem (Armitage Labs OU, Estonia) Processes payments as merchant of record, and holds the billing record for your purchase
MailerLite Sends course and marketing emails, if you have opted in
Microsoft Clarity Shows me how visitors use the pages, so I can fix what is confusing
Cloudflare and Netlify Deliver the site and the course apps quickly and securely

Each of these has its own privacy policy. They are only permitted to use your information to provide their service to NDTPrep.

Cookies

NDTPrep uses cookies and similar technology for three things:

  • To keep you signed in and remember your place in a course
  • To measure which pages are used, through Microsoft Clarity
  • To keep the site secure

You can block or delete cookies in your browser settings. If you block the essential ones, signing in and saving your progress will stop working.

How long I keep it

I keep your student account and course progress for as long as your account exists, so you can come back to it. Purchase and billing records are kept for as long as the law requires.

If you ask me to delete your account, I will delete it, apart from any record I am legally required to keep.

Your rights

Wherever you are in the world, you can ask me to:

  • Tell you what information I hold about you
  • Correct anything that is wrong
  • Delete your account and your personal information
  • Stop sending you marketing email
  • Send you a copy of your information

Email support@ndtprep.com and I will action it. I aim to reply within 5 working days and to complete the request within 30 days.

Every marketing email also carries an unsubscribe link at the bottom. One click and you are off the list. Unsubscribing does not remove your course access.

The law that applies

NDTPrep is based in South Africa and follows the Protection of Personal Information Act, known as POPIA.

Divers buy these courses from all over the world. If you are in the United Kingdom or the European Union, I also honour the rights the UK GDPR and the EU GDPR give you. Those are the same rights listed above.

If you believe I have not handled your information properly, you can complain to the South African Information Regulator at inforegulator.org.za. I would rather you told me first, so I get the chance to put it right.

Security

Your account sits behind the security of the platforms listed above, which use encryption in transit and at rest. No system online is perfect, so if something goes wrong that affects your information, I will tell you.

Children and international transfers

NDTPrep is professional training for working commercial divers. It is not intended for anyone under 18, and I do not knowingly collect information from children.

NDTPrep uses services based in several countries, so your information may be stored or processed outside the country you live in. The services listed above are bound to protect it to the standard described in this policy.

Changes, and how to reach me

If I change this policy I will update the date at the top of this page. If the change is significant, I will also tell existing students by email.

Any question, any request, any complaint about your information, email support@ndtprep.com.
