What cookies are
Cookies are small text files that a website places on your device.
They help the site work, remember your choices, and show us how the site is being used.
Some cookies are set by us.
Others are set by trusted partners whose tools we use.
That's the whole idea. Nothing more mysterious than that.
How we ask you
When you first visit qed42.com, you see a short banner.
It lets you choose which cookies we may use.
You can accept all, reject all non-essential cookies, or set your preferences by category. The accept and reject options sit side by side, with equal weight.
We only place non-essential cookies after you say yes. Until then, they stay off.
If you reject the non-essential ones, you can still use the site fully. Nothing here hides behind a cookie wall.
Essential cookies keep the site secure and working, so they stay on. Everything else is your choice.
Changing your mind
You can change or withdraw your consent at any time.
Use the cookie settings link in our footer to reopen your preferences.
Withdrawing is as easy as agreeing.
As soon as you update your settings, we stop the related data collection.

The partners behind these cookies
Some cookies come from trusted partners. Here are the main ones.
We use Google Analytics 4 to see how you use the site so we can make it better. It measures things like how long you spend on a page and which pages you visit.
We use Microsoft Clarity to understand usage patterns and see where people focus.
We use HubSpot and LinkedIn for marketing analytics and audience insight.
We use Cloudflare for security and performance.
These partners help us measure the site and reach the right audiences. From time to time, we test new features and make small changes to how the site is delivered, and some cookies help keep your experience steady while we do.
For users in India
We operate from India, and we line our cookie practices up with the Digital Personal Data Protection Act, 2023 and its rules.
We treat your consent as the basis for cookies that process your personal data.
We show you a clear notice and give you choices in supported languages as the rules require.
You can give, manage, and withdraw consent through the banner and the cookie settings link.
For any questions or to reach our grievance contact, write to [email protected] or visit qed42.com/contact.
For users in Europe (EEA)
If you are in the European Economic Area, the ePrivacy Directive and the GDPR apply.
We ask for your consent before we place any non-essential cookie, and nothing non-essential loads until you choose.
Your reject option carries the same weight as accept, and you can withdraw at any time.
You can also ask to see, correct, or delete the personal data tied to these cookies, or object to how it is used. Write to [email protected].
For users in the United Kingdom
If you are in the UK, PECR and the UK GDPR apply, overseen by the Information Commissioner's Office.
The approach is the same as for the EEA. We ask before we set non-essential cookies, we give reject and accept equal prominence, and we keep a record of your choice.
You can manage or withdraw consent any time through the cookie settings link, and you can reach the ICO if you ever feel your choice was not respected.
For users in California
If you are a California resident, you can opt out of the sale or sharing of your personal information, including data used for cross-context behavioural advertising.
Use the "Do not sell or share my personal information" link in our footer.
When you opt out, we stop placing the advertising cookies that share your information with third parties.
For users in other regions
Wherever you are, the same principles hold.
We ask before we set non-essential cookies, we tell you what each one does, and we let you change your mind.
If your region gives you specific rights over this data, such as Brazil under the LGPD or Canada under PIPEDA, you can exercise them by writing to [email protected].
How to manage cookies
You have two ways to stay in control.
Use our banner and the cookie settings link in the footer to set your preferences by category, any time.
Or adjust your browser settings to block or delete cookies. Check your browser's help section for how. Blocking some cookies may change how parts of this and other sites work.
