Privacy Policy
What this site collects, what it doesn't, and how advertising works here. Written to be read, not to be agreed to in a hurry.
Last updated: 21 July 2026
The short version
The calculator runs entirely in your browser. No birth date you enter here is sent to any server — Numeluna never sees it. We don't run accounts, collect email addresses, or track you across sessions.
What we do use: advertising served by Google AdSense, which involves cookies and may use your browsing history to personalise the ads you see. The rest of this policy explains that in plain terms and tells you how to opt out.
What we collect
Nothing from the calculator. The numbers you work out stay in your browser. They are not logged, stored, or transmitted.
Standard server logs. When you request a page, our hosting provider records your IP address, the URL, your browser type, and the date and time of the request. This is standard practice and outside our direct control. Logs are retained for a short period for security purposes and then deleted.
Cookies from third-party services. We don't set our own tracking cookies. The third-party services described below do.
Advertising and cookies
Numeluna uses Google AdSense to display advertisements. Google and its partners use cookies to serve ads based on your prior visits to this site and other sites across the web. This is called interest-based or personalised advertising.
In plain terms: Google may remember that you visited numeluna.com and use that, along with your broader browsing activity, to decide which ads to show you elsewhere — and vice versa.
Google's use of advertising cookies is governed by Google's advertising policies. For more on how Google uses data when you visit sites that use its services, see How Google uses information from sites or apps that use our services.
Your choices
You can opt out of personalised advertising at any time. Doing so means you'll still see ads — just ones that aren't tailored to your browsing history.
- Google Ads Settings — manage how Google personalises ads across all sites: google.com/settings/ads
- YourAdChoices — opt out from multiple ad networks at once: aboutads.info/choices
- Browser-level controls — most browsers let you block or delete cookies entirely. Check your browser's privacy settings.
Numeluna itself holds no personal data about you — there are no accounts, no stored inputs, and no server-side user records to access or delete. If you're in the European Economic Area and want to exercise GDPR rights over data collected by a third-party service on this site (Google AdSense, for instance), those requests go directly to that provider. We're happy to help you figure out where to direct them — email hello@numeluna.com.
Third-party services
The only third-party service currently active on this site is Google AdSense (advertising). Their privacy policy: policies.google.com/privacy.
We may add other services over time — analytics, for instance — and will update this policy and the list above when we do.
Children
Numeluna is not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal data, contact us and we'll remove it.
Changes to this policy
We'll update this page if anything material changes and revise the date at the top. We won't send you a notice — but then, we don't have your email address, so that was never on the table.
Questions
If something here is unclear or you have a request: hello@numeluna.com.
