How TwinklPD Uses Cookies and Similar Technologies

1. About This Policy

This website is operated by TwinklPD (“TwinklPD”, “we”, “our”, or “us”). We are committed to protecting your data and being clear about how we use cookies and similar technologies. These tools help our website function properly, personalise your experience, and support features like analytics, advertising and embedded social media content.


Below you will find a layered explanation of the types of cookies and similar technologies we use, why we use them, and how you can manage your preferences.

If you would like to understand more about how we handle personal data, please see our TwinklPD Privacy Policy.

2. What are cookies and similar technologies?


A cookie is a small text file that’s stored on your device—like your computer, tablet, or phone—when you visit a website. Cookies can help a website remember who you are and what you’ve done on previous visits. For example, they can keep you logged in, save your chosen language or country, or help a site remember what you’ve searched for.

Not all tools are cookies. Some similar technologies work in different ways but serve similar purposes. These may include:


  • Local storage and session storage: These are saved by your web browser and can store things like settings, preferences, or form data.
  • Tracking pixels or web beacons: Tiny, invisible images that let us know if you’ve opened an email or visited a page.
  • JavaScript tags: Pieces of code that help collect information about how you interact with our website.
  • Device fingerprinting: A method of identifying your device based on its unique features (like browser type, screen resolution, or language settings).
  • SDKs (Software Development Kits): Often used in mobile apps, SDKs collect data in a similar way to cookies on websites.


These tools are often used together to give you a seamless, personalised, and secure experience across TwinkPDl’s platforms.

3. Different types of cookies and similar technologies

Cookies and similar technologies can vary in how they are set and how long they last. To help you understand the differences, we group them by who sets them and how long they stay active.


By Who Sets Them (Origin)

  • First-party - these are set directly by TwinklPD when you use our website. For example, we use a first-party cookie to keep you logged in or remember your preferred language.
  • Third-party - these are set by our trusted partners—like Google or Stripe—when their tools or services are used on our site. They may help us with things like payment processing, advertising personalisation, or social media features.

By How Long They Last (Duration)
  • Session-based- these are temporary and are deleted automatically when you close your browser. They help with things like keeping you logged in during your visit or remembering what you’ve searched for. This category can also include some types of session storage.
  • Persistent - these remain on your device even after you close your browser. They’re used to remember your settings or preferences for next time—for example, your selected country or your progress through a resource. Persistent tools can include traditional cookies as well as similar technologies like local storage.

While cookies follow standard expiry rules, similar technologies (like local storage) may stay on your device until your browser is cleared or they are removed manually.
You can learn more about the specific cookies and similar technologies we use in the sections that follow, including how long they last and whether they’re set by TwinklPD or one of our trusted partners.

4. How we use cookies and similar technologies

We use cookies and similar technologies to support key features of the TwinklPD Website and improve your overall experience. These tools help us operate securely, understand how the site is used, and personalise adverts and content for you.
Here are some of the key purposes:

5. Cookies and similar technologies we use

We have classified the cookies and similar technologies into the following categories:
  1. Strictly Necessary
  2. Functional
  3. Analytics
  4. Advertising


Strictly Necessary Cookies

Strictly necessary cookies and similar technologies are essential for the website to function safely and correctly. They allow core features to work—such as secure login, remembering your selected settings (like role, country, or language), and helping content display as intended. These technologies do not store any information that can directly identify you and do not require your consent. These cannot be disabled through our cookie settings, as doing so would prevent parts of the website from functioning.

Istituto Johanson collects and stores your personal and identifying data (such as given name, surname, residential address, email address, courses of interest, citizenship, gender, place and date of birth, telephone number) through the following channel.

These tools help create a smoother, more tailored experience based on your interactions. They may be set by us or by trusted third-party providers offering services on our site.

Analytics Cookies

Analytics cookies and similar technologies help us understand how people use our website—such as which pages are visited, how long users stay, or where they encounter issues. We use this data to improve how the site works and ensure content is helpful and accessible. These tools often use aggregated, anonymised information and are provided by trusted partners like Google Analytics and Microsoft Clarity. If these technologies are disabled, we’ll have limited insight into how our website is performing or where improvements are needed, which may affect our ability to make the site better for users.
See list set out below:

Advertising Cookies

Advertising cookies and similar technologies are used to deliver adverts that are more relevant to you and your interests. They may also help limit how often you see a particular ad and measure the effectiveness of advertising campaigns across websites and platforms. These tools help TwinklPD and our trusted partners (such as Google) build anonymous profiles based on your browsing behaviour, so we can show you more useful and personalised content, both on our website and elsewhere online. If you choose to disable these technologies, we won’t be able to personalise advertising or accurately measure how well our campaigns are performing. This may affect our ability to improve the way we promote relevant content and services to you.
