In short
- Calculations run in your browser: the values you enter in the calculators are not sent to or stored on our systems.
- We do not use cookies for tracking or analytics, and no third-party tracking tools.
- The site is hosted on Cloudflare, which processes some technical data to deliver pages and protect them from attacks.
Technical browsing data
When you open a page, your browser automatically sends some technical data: IP address, date and time, the page requested, browser and operating system. This is needed to deliver the page and to protect the site from abuse and attacks.
This data is processed by Cloudflare, Inc., which provides hosting and content delivery and acts as our processor. Cloudflare may process data outside the European Union with the safeguards required by the GDPR (EU-US Data Privacy Framework and standard contractual clauses). Details: Cloudflare’s privacy policy.
Legal basis: our legitimate interest in running the site and keeping it secure (Art. 6(1)(f) GDPR). We do not use this data to identify or profile you.
Values entered in the calculators
Amounts, rates and terms stay on your device. So that you can save or share a calculation, the values are written into the page address (for example ?amount=20000&rate=6.5). This happens only in your browser. The address reaches the server only if you open or share that link, in which case it is part of the technical data described above. If you’d rather it didn’t, don’t share the link.
Browser storage
We store a few technical preferences in your browser’s localStorage: light or dark theme, chosen language and calculator currency. They stay on your device, are never sent to us, and only remember your choices. You can delete them at any time in your browser settings.
The site also uses a service worker that keeps a copy of visited pages on your device so they load faster and work offline. It contains no personal data.
If you write to contact@numrova.com, we use your address and message only to reply. Legal basis: your request (Art. 6(1)(b) GDPR). We keep the correspondence as long as needed to handle it, and no longer than 24 months. Emails are forwarded through Cloudflare Email Routing to a Gmail (Google) mailbox, which acts as our email provider.
Advertising
The site does not show ads at the moment. If we use advertising services such as Google AdSense in the future, we will update this policy before turning them on. Visitors from the European Economic Area, the UK and Switzerland will be asked for consent through a certified consent management platform before any advertising cookies are used.
Your rights
You can ask us at any time to access, correct or delete your data, or to restrict its processing. You can also object to processing and request data portability (Articles 15–22 GDPR) by writing to contact@numrova.com.
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) or the supervisory authority in your country.
Changes
We may update this policy, for example when we add new services. The date of the last update is shown at the bottom of the page.
