We collect the data we need to answer your quote request, and nothing else. There is no advertising, there are no profiles, we do not sell or pass data to third parties for marketing purposes, and this site has no traffic analysis tools.

3. Who else handles the data
We work with few intermediaries, and these are they.

No receives neither your IP address, nor your browsing history, nor the source of the visit. |
Sharing with the manufacturer is based on the legitimate interest in preparing and fulfilling the supply you asked us for — point f) of Article 6 of the GDPR. From then on the manufacturer processes the data as independent controller, under its own privacy policy and with its own time limits: it may contact you regarding this request and any communications it sends you are its responsibility, including the right to object, which you exercise with it.
If you would prefer your request no is shared, just tell us — the quote is prepared all the same. And if you want to know exactly which entity it is, we will identify it on request.
Some of these services may involve transferring data outside the European Economic Area, under the standard contractual clauses approved by the European Commission. We do not sell data and we do not share it for advertising purposes.
