Trust seal
We don't collect your personal data. That's why we cannot sell or share it.
If we don't have it, we can't use it.
The system
Many platforms say: "we collect data but we don't share it." This system changes the paradigm.
Traditional model"We collect data but we don't sell it."
No Data Found"We don't collect personal data, so it cannot be sold, shared or exploited."
It's not about trusting how data is used — it's about removing the need for trust because personal data simply doesn't exist within the system.
The analogy
Imagine your favourite website as an ordinary shop. The door is open. Anyone can walk in. You can browse, compare, and leave without buying anything. It's normal and nobody finds it strange. An everyday thing.
They'd have a general picture. The kind our social interactions have produced for millennia. The everyday norm.
That would be intrusive. Outside the norm. Private.
The digital equivalent has broken this balance. Many websites do ask you to identify yourself before entering, do follow you into every section, do measure every glance, and do build a profile that lasts forever.
No Data Found doesn't ask sites to operate without data. It asks that the basic experience — coming in and browsing — be data-free, because none is needed. If you click, ask, buy, or return something, it's normal that some personal-data interaction takes place; otherwise nothing can work. But only then. And only the data strictly needed for that action. Nothing more.
A site carrying the No Data Found seal can absolutely process personal data — most do at some point (contact forms, orders, personalised searches...). What defines the seal isn't a total absence of data, but how and when it's used.
