Privacy Policy

Ilchido has no sign-up. We do not ask for your name, email, phone number, or any other contact details. The only information you enter, used to calculate your readings, is:

• Date of birth, time of birth (optional), gender, and place of birth (optional)
• Usage within the app: readings you open, your daily pick, after-the-fact feedback (liked it / so-so / no), and unlock status

All of the above is stored only in your browser (localStorage) and is never transmitted to our servers. Every reading is also calculated entirely on your own device, inside the browser. As a result, we have no way to see your birth information.

Information saved in your browser stays on that device until you remove it. You can delete it yourself at any time:

• Clear this site's data (cookies and storage) from your browser settings
• Or clear your browser's full browsing history

Deleting removes your birth information, pick history, and unlock status all at once, and it cannot be recovered, because no server copy exists.

To improve the service, we may use the analytics tools below. They use cookies or similar technologies to collect non-identifying usage statistics such as the pages you visit, how long you stay, and your device type. The birth information you enter, such as your date of birth, is never sent to these tools.

• Google Analytics 4 (Google LLC) for visit and usage statistics
• Microsoft Clarity (Microsoft Corp.) for behavioral analysis (heatmaps and session replay)

For details on how each tool processes information, please refer to the privacy policies of Google and Microsoft. You can opt out using your browser's cookie-blocking settings or an ad blocker, and doing so does not limit your use of the service.

To keep the service free, Ilchido may display Google AdSense ads. Third-party ad vendors, including Google, may use cookies to show ads tailored to your previous visits.

• You can find more on Google's use of advertising cookies in Google's advertising policy pages.
• You can turn off personalized advertising in Google Ad Settings.
• You can also opt out of third-party vendor advertising at www.aboutads.info.

We do not hold any of your personal information, so there is nothing for us to share with or hand off to third parties. The analytics and advertising tools in Sections 3 and 4 are cases where each vendor collects non-identifying information under its own responsibility.

Ilchido is not directed at children under 14, and we do not knowingly collect information from children.

Because everything you enter lives only on your device, you can exercise your rights to access, correct, and delete it yourself. You can edit your birth information from the "Birth Info" menu in the app, and you can delete everything using the methods in Section 2. For anything else, please reach out using the contact below.

If this policy changes, we will post the update on this page, and we will clearly notify you of any significant change (for example, introducing server-side storage) before it takes effect.
