Privacy Policy

1. Information we collect

1.1 No personal profiles

We designed the calculator to run entirely in your browser. Birth details and analysis results are processed locally and never transmitted to our servers.

Your birth year, month, day and hour are used only to generate a chart within the current session.
The Bazi interpretation is rendered on the client side; we cannot view or retrieve your input.
We do not build user accounts, behavioural profiles or marketing segments.
Basic technical logs (e.g., IP address, browser type) may be produced by our hosting provider for uptime monitoring.

1.2 Cookies & tracking

Only minimal cookies are used to support functionality:

Essential cookies to remember interface states (e.g., language choice).
Advertising partners such as Google AdSense may set cookies to deliver relevant ads. Refer to their privacy policy for details.
You can clear or block cookies through your browser settings without losing access to the core service.

2. How we use information

Our guiding principle is data minimisation.

All Bazi calculations stay on your device—no data is uploaded for processing.
Anonymous analytics help us understand feature usage and improve performance.
Operational logs are reviewed only to diagnose technical issues or secure the service.
We comply with applicable privacy regulations and honour lawful requests.

3. Data security

Because we do not maintain personal databases, your birth data remains under your control.

HTTPS encryption protects all traffic between your browser and our site.
Client-side computation ensures sensitive details never leave your device.
We continually update dependencies and hosting infrastructure to reduce vulnerabilities.

4. Your rights

You may delete stored results at any time by clearing your browser cache or local storage.
Because we do not store personal data, there is no account information to remove from our systems.
Manage cookies and advertising preferences directly within your browser or via AdSense settings.

5. Third-party services

We collaborate with trusted partners to keep the site running.

Google AdSense

Advertising helps us maintain the free calculator. Google may personalise ads using its own cookies. Learn more in the Google Privacy Policy.

6. Policy updates

We may revise this document to reflect new features, regulations or partners. Significant changes will be announced on this page. We recommend reviewing the policy periodically.
