Privacy Policy

Effective date: July 22, 2026

Calculator input: A birth date or birth time entered into the calculator is processed locally in your browser. It is not submitted to our server, added to the page URL, or stored by the calculator after the page is closed.

Technical data

Our hosting provider may process ordinary request information needed to deliver and protect the site, such as IP address, request time, requested URL, browser or device information, referrer, response status, and security signals. This information may be retained in hosting and security logs according to the provider's settings and policies.

Cookies, analytics, and advertising

The current site code does not load an analytics service or set an advertising cookie. If analytics or Google AdSense is enabled later, this policy and the site's consent controls will be updated before activation.

Advertising providers, including Google, may use cookies, web beacons, IP addresses, or other identifiers to serve, measure, limit, and personalize ads where permitted. Third parties may place or read cookies in your browser or use web beacons or IP addresses as a result of ad serving. Learn how Google uses information from sites or apps that use its services and review Google advertising controls.

Consent

Where consent is legally required, non-essential analytics or personalized advertising will not be activated until the required choice has been obtained through an appropriate consent management platform. Users must be able to accept, reject, and manage applicable choices.

Data sharing and sale

We do not sell calculator input. Technical information may be processed by service providers acting for hosting, security, consent management, analytics, or advertising, subject to their contracts and privacy terms. We may disclose information when required by law or necessary to protect the service and users.

Children

The site is a general-audience utility and is not directed to children under 13. Do not submit personal information about a child by email. If the site is later treated as child-directed, advertising and measurement settings must be configured accordingly.

Your choices and requests

You can limit cookies through your browser and use the controls offered by advertising providers. Depending on where you live, you may have rights concerning access, deletion, correction, restriction, objection, or withdrawal of consent. Send requests through the contact page. We may need to verify a request before acting on it.

Changes

We will update this policy when technologies or data practices change and revise the effective date above. Material changes will be communicated through the site where appropriate.
