What data we process
| Data | Why | Legal basis | How long |
|---|---|---|---|
| Browsing data: IP address, date and time, page requested, browser (web server logs) | Running the site and protecting it from abuse and attacks | Legitimate interest (Art. 6(1)(f) GDPR) | Up to 14 days, then deleted |
| IP address, in memory only | Limiting the number of calculations per minute from the same address | Legitimate interest (Art. 6(1)(f) GDPR) | About one minute, never written to disk |
| Email address and content of messages you send us | Answering requests for analyses, quotes or API keys | Pre-contractual steps and contract (Art. 6(1)(b) GDPR) | For the duration of the request or relationship, then as required by law |
The data you enter in the calculator (composition, energy use, countries, transport) describes a product, not a person. It is used only to run the calculation and is not stored.
We do not use profiling cookies, analytics, advertising pixels or social media plugins. See the cookie policy.
Who can see the data
The site is hosted on a server operated by IONOS SE (Germany), acting as data processor. Emails pass through our email provider. We do not sell or share data with third parties and do not use it for automated decisions or profiling.
Fonts are served from our own server: opening the site does not make your browser contact Google or other external services. Links to other sites (for example ChainWear or the data sources) lead to pages with their own privacy notice.
Your rights
You can ask at any time to access, correct or delete your data, restrict its processing, receive it in a portable format or object to processing (Articles 15-22 GDPR). Just write to info@chainwear.it; we reply within one month.
If you believe the processing breaches the GDPR you can lodge a complaint with the Italian Data Protection Authority, Garante per la protezione dei dati personali (www.garanteprivacy.it), or with the authority of your country.
Changes
If we change how we process data we will update this page and the date at the top.
