1. General principle
Nhật Nguyệt is built on the principle that logging in is NEVER required to use any lookup tool. Logging in is optional and only unlocks personalization. If you don't log in, we don't collect any personally identifying information from you beyond ordinary anonymous traffic data (see section 4).
2. Data we collect when you log in
When you choose to log in via Google or Apple, we receive from that provider: your email, display name, and profile picture (if available). We NEVER receive or store your Google/Apple account password.
You may VOLUNTARILY provide: birth date, birth hour, and gender, used to auto-fill lookup tools (Tử Vi, numerology, etc.) and personalize article suggestions. Not providing this has no effect on your ability to use any tool.
If you enable reminders, we store the content and dates you create. If you read articles while logged in, we keep a list of recently viewed articles to make "For You" suggestions more relevant, used for no other purpose.
3. Purpose of data use
Data you provide is used ONLY to: (a) auto-fill lookup tools so you don't re-enter it; (b) suggest articles matched to your zodiac and reading history; (c) send reminders you set yourself (once real notification delivery is deployed); (d) maintain your login session.
We do NOT sell, rent, or trade your personal data to third parties for commercial purposes.
4. Anonymous traffic data & Google Analytics
Nhật Nguyệt may use Google Analytics to measure overall traffic (page views, device type, city/country-level location) to improve the experience, this data is aggregated and not tied to your specific identity. See Google's privacy policy at policies.google.com/privacy.
For public articles, we count views per article to surface popular content (the "Suggested" section of the knowledge base), this count is NOT tied to a specific viewer's identity, only a per-article, per-day counter.
5. Advertising
Nhật Nguyệt may display ads via Google AdSense to sustain free operation. Google and its advertising partners may use cookies to show more relevant ads based on your browsing activity across sites, you can turn off ad personalization in your Google account settings at adssettings.google.com.
6. Storage & security
User data is stored on Nhật Nguyệt's server infrastructure. Login sessions are authenticated via time-limited tokens; we never store passwords in any form (authentication is entirely delegated to Google/Apple).
No system is 100% secure, we apply reasonable security measures but cannot guarantee absolute protection against every attack.
7. Your data rights
You can view and edit your personal profile and reminders at any time in your Account page.
You can delete individual reminders directly in the interface. To delete your entire account's data (including reading history), please contact [email protected], we'll process it as soon as possible.
Logging out does not delete saved data, it remains available when you log back in, until you actively delete it.
8. Cookies & browser storage
Nhật Nguyệt uses your browser's localStorage to keep your login session (token) on your own device, we don't use cross-site tracking cookies for our own personalization. Google Analytics/AdSense (if enabled) may set their own cookies per Google's policies.
9. Children's privacy
Nhật Nguyệt is not directed at children under 13 and does not knowingly collect data from them. If we learn that a child under 13 has provided personal data, we will delete it upon notice.
10. Changes to this policy
This policy may be updated to accurately reflect how data is collected/used as features change. The most recent update date is always shown at the top of this page.
11. Public figure profiles and the right to have one removed
Nhat Nguyet hosts profiles of some public figures, built from information already published in mainstream press, alongside numerology and astrology readings. Those readings are cultural convention offered as reference, not a judgement about a real person, and we say so on every profile.
If a profile is about you and you would rather it did not exist, write to [email protected] with the link. We take it down. We do not ask why and we do not ask you to prove anything. That is deliberate: if someone wants their name off this site, their reasons are their own.
We also correct or remove profiles when someone reports an error, such as a wrong birth date or a case of mistaken identity. If you want a correction rather than a removal, say so and include a source.
12. Contact
