Is My Data Private? Does the Tool Send Data to a Server?
Yes — completely private. The Lunar Calendar Converter processes everything inside your own browser. No names, birth dates, or any other information you enter are ever transmitted to any server, stored in any database, or shared with any third party.
How it works — entirely client-side
Most web applications work by sending your input to a server, which processes it and sends back a result. This tool works differently: all of the logic — the lunar-to-Gregorian date conversions, the holiday calculations, and the .ics file generation — runs entirely as JavaScript code in your own browser, on your own device.
When you click "Generate Calendar", your browser performs all the calculations locally. The resulting calendar file is assembled in memory and offered to you as a download — without ever leaving your computer.
What is and is not collected
- ✅ Names you type — never sent anywhere; processed only in your browser memory
- ✅ Birth dates you enter — never sent anywhere; used only for local calculation
- ✅ The generated .ics file — created entirely on your device; never uploaded
- ✅ No cookies — the tool sets no tracking or analytics cookies
- ✅ No analytics — no Google Analytics, no tracking pixels, no session recording
- ✅ No account required — you do not need to register or log in
What the server does receive
When you visit the page, your browser makes standard HTTP requests to load the HTML, CSS, JavaScript files, and the Google Fonts used for typography. These requests include your IP address as part of normal web browsing — this is true of every website you visit and is not specific to this tool. The font files are loaded from Google's servers (fonts.gstatic.com); Google's privacy policy applies to those requests.
No personal information you enter into the form is ever included in any of these requests.
The Content Security Policy
This website uses a strict Content Security Policy (CSP) header, which instructs your browser to block any outgoing data connections that are not explicitly allowed. The policy includes connect-src 'none' — meaning the page is technically prevented from sending data to any external server, even if the code tried to do so. This provides a technical guarantee of privacy, not just a policy promise.
GDPR and data protection
Because no personal data is collected or processed on any server, this tool does not require a cookie consent banner, a privacy policy covering personal data processing, or GDPR data subject request procedures. There is simply no data to manage. You remain in full control of all information you enter at all times.
