Cookie notice
Exactly what this site stores on your device, and what it does not.
What this site stores
The site stores three items on your device. All are strictly necessary for the site to work as you expect, and all are first party.
| Name | Type | Purpose | Kept for |
|---|---|---|---|
nt_ruo | Cookie, first party | Records that you accepted the research-use-only notice, so it is not shown on every page. | 1 year |
nt_consent | Cookie, first party | Records your choice in the cookie notice: necessary only, or also advertising measurement. | 1 year |
nt.basket.v1 | Local storage | Your inquiry list: compound, size and quantity for each line. It stays in your browser and is sent to us only when you submit an inquiry. | Until you send the inquiry, clear the list or clear your browser data |
The cookies hold no personal data and no identifier: nt_ruo has the value 1, and nt_consent holds a version number and a single letter for your choice.
Statistics without cookies
We count page views and a few key actions on our own server, without cookies or browser storage. Visitors are counted with a hash that changes every day and cannot be traced back to an IP address; the IP address itself is not stored, and records are deleted after 400 days. Visits from browsers that send Do Not Track or Global Privacy Control are not recorded. The privacy policy lists exactly what is recorded.
Optional: advertising measurement
This site does not currently load any Google or other third-party tag, so there is nothing optional to choose. If advertising measurement is added, it will load only with your permission.
Changing your choice
You can reopen the cookie notice at any time with "Cookie settings" in the footer. You can also delete cookies and local storage in your browser settings; the research-use notice and the cookie notice will then be shown again, and your inquiry list will be emptied.
