This policy explains what information is processed when you use romanumerals.com, by whom and why, and what choices and rights you have. It is in effect from 11 November 2026. The English version is the reference; if a translation differs, the English version prevails.
Who is responsible
The site is operated by Romanumerals, which is the controller of the data described here. For any privacy question or request, write to [email protected].
What we collect
Romanumerals has no user accounts and no contact form, and we don't ask you for your name, email or other personal details to use the tools. Information is processed in three ways:
- Cookies and similar identifiers set by third parties for advertising and statistics: Google AdSense, Google Analytics and Microsoft Clarity, described below.
- Technical data that every web server receives, such as your IP address, browser type and the page requested. Our server may record it in technical logs to keep the site running and secure.
- Storage in your own browser. The site saves your light or dark theme preference in your browser's local storage. It stays on your device and is not sent to us.
If you email us, we receive your email address and whatever you include in the message, and use them only to answer you.
Advertising: Google AdSense
The site shows ads served by Google AdSense. Google and its partners use cookies and other identifiers to show ads, including ads based on your interests (personalised ads), to limit how often you see an ad and to measure performance. Where you don't consent to personalised ads, Google may still show non-personalised ads, which are based on the context of the page and your approximate location rather than your profile.
Google explains how it uses information from sites that use its services in How Google uses information from sites or apps that use our services. You can manage the ads Google shows you in My Ad Center.
Your consent choices
If you visit from the European Economic Area, the UK or Switzerland, a consent message from Google, a consent management platform certified by Google and integrated with the IAB Transparency and Consent Framework, asks which uses of cookies you allow. Until you choose, advertising and analytics cookies stay off in those regions. Ads, analytics and Clarity follow your choice.
You can change or withdraw your choice at any time through the consent options offered by that message, or by deleting this site's cookies in your browser, which makes the message appear again.
Statistics: Google Analytics
We use Google Analytics 4 to understand how the site is used in aggregate: which pages are visited, from what kind of device, from which country and how visitors arrive. Analytics runs in Google Consent Mode, so in the regions above it only uses cookies if you consent. Google keeps this data for the retention period configured in our Analytics account and then deletes it. More in Google's Privacy Policy.
Usage analysis: Microsoft Clarity
We use Microsoft Clarity to see how pages are used, through heatmaps and session recordings, so we can fix layout and usability problems. Clarity sets its own cookies and, in the regions above, only runs with your consent. We don't use it to identify you. More in the Microsoft Privacy Statement.
Legal bases
Where the law requires it (for example in the EEA, the UK and Switzerland), advertising and analytics cookies are used on the basis of your consent, which you can withdraw at any time. Technical data needed to deliver and protect the site is processed on the basis of our legitimate interest in running a secure, working website.
International transfers
Google and Microsoft process data on servers in several countries, including outside the country you are in. They rely on the safeguards provided for by law for these transfers, as described in their privacy policies.
Your rights
Depending on where you live, laws such as the GDPR, the UK GDPR, the Brazilian LGPD and US state privacy laws give you rights over your personal data, including to:
- access the data held about you and get a copy;
- correct it or ask for it to be deleted;
- object to or restrict its processing;
- withdraw your consent at any time, without affecting what was done before;
- complain to a data protection authority, for example the ANPD in Brazil, the Garante per la protezione dei dati personali in Italy or the authority of your own country.
To exercise these rights, email [email protected]. For data held by Google or Microsoft, you can also use the tools they provide in the policies linked above.
Children
Romanumerals is a general-audience site. It is not directed at children, although students of any age use it to learn. We don't knowingly collect personal information from children. If you believe a child has sent us personal information by email, write to us and we will delete it.
