For now, you can explore one person's chart. Paired and work readings are not available yet.
BaZi is part of the Chinese tradition of reflecting on people and their paths through life. Its symbolic language offers another view of familiar decisions, relationships and aspirations, helping you look more closely at your own experience and possibilities.

Your personal
reading.
A short reading of your birth chart: sources of support, familiar rhythms and questions to help you understand yourself better.
Your short personal reading is below. The river, tree, fire and other images come from the symbolic language of BaZi and relate to your calculated birth chart. They are metaphors for reflection, not literal human traits. Try them against your experience; the questions at the end can help you notice what resonates with you.
The Book of Your Nature
Continue
getting to know yourself.
Your chart is a starting point. Your experience is what makes the reading personal.
More connections.
More room for yourself.
14 sections on inner support, choice, resources, work, closeness and change. Year themes: three past years to compare with your experience, the current year and the next six. The themes for the coming 12 months explore traditional sources of support, supportive and strained energy, and attention to workload. Ten-year period themes are included only when there is enough data. You'll see the contents and limitations before ordering.
The book is currently created without payment. No money is charged.

About the book
Control over your data
Guest access.
No registration or sign-in. A new guest session is created for 30 days. Without a verified email, the data is available until that period ends; a new reading does not restart it. Your name is optional; if you provide it, we'll save it with the reading. Without a verified email, calculations are linked to this browser: clearing cookies or using another device will not give you access to them. A cookie is necessary for guest access and follows the session's server-side lifetime: initially 30 days, and potentially longer after email verification.
A cookie is necessary for the service to work; there are no advertising SDKs, analytics or external resources here.
Short readings and full books are saved on the server with the chart. We create them with the help of our technical partner, the AI service Anthropic (USA). We ask for consent when you submit the form; a book starts only after a separate order. Only derived facts from the calculated chart are sent to Anthropic: your name, original birth date, birth time and time zone are not sent. AI text can be wrong. BaZi is a traditional symbolic approach for reflection and comparison with your experience. Its images and period themes do not replace medical, financial or psychological advice. The Delete My Data button removes all calculations, names, short readings and books belonging to the current guest and ends guest access on every device. Files already downloaded stay with you. Deleted data cannot be restored through the interface.
For new charts, you can choose a city from the local GeoNames directory. We save the selected place, city-centre coordinates, zone, and comparison of civil and true solar time; search queries are not saved or sent to an external geocoder. We do not request your device's location. The directory does not include every settlement or every translated name: if your city is missing, choose the zone manually — solar calculation is unavailable without longitude. The place and coordinates are not sent to Anthropic and are deleted with the reading. The traditional reference's symbolic climate is not weather or the geography of your birthplace.
Solar time accounts for longitude and the equation of time; historical clock changes come from the pinned IANA TZDB 2026e. The main day boundary is 00:00; for solar time 23:00–24:00, we separately show the traditional alternative of a 23:00 boundary without replacing the main chart. When the time is unknown, all valid variants of the original civil day remain. We do not recalculate old charts. The accuracy of historical zones and the astronomical model is limited, especially for early dates; the city centre does not give maternity-hospital precision.
City data: GeoNames (geonames.org), CC BY 4.0 licence — creativecommons.org/licenses/by/4.0. The local dataset of cities with more than 15 thousand residents and capitals, with Russian and English alternative names, was prepared on 6 November 2026; names are normalised for search. The data is provided without warranties.
Sex is optional at every level of time precision. If you specify it and confirm the new consent, we'll save the parameter with the original details of the new chart and use it for the traditional rule for the direction of luck cycles and conventional partner and child correspondences in the full book. We do not infer it from your name or other details. The parameter and correspondences do not define your identity, actual family or whether you have a partner or children, and do not attribute traits to real relatives. The short AI reading remains an ordinary chart reading without the new family correspondences.
For new calculations, ten-year life periods can be calculated when sex is specified and birth time is exact or approximate. With a valid structure, time uncertainty is preserved as an age range; different directions or sequences of Luck Pillars make a single calculation unavailable. Without sex or with an unknown time, Luck Pillars are not calculated. This is a conventional traditional conversion: age ranges describe period themes, not dates of events or lifespan. Old saved calculations and consents are not updated.
Your name, original date, time, time zone and the value of the sex parameter itself are not sent to Anthropic. Only necessary calculated features are sent, including cycles with rounded age intervals and, for a new book with new consent, derived traditional partner and child correspondences. This data cannot be considered anonymous: the correspondences and cycle direction or sequence, together with chart features, may reveal the selected sex category, and the intervals may narrow down the birth time. Old saved consents do not authorise the new sex-dependent family correspondences, even with a separate book order.
Exact intermediate values in the new cycle calculation are neither saved nor sent to AI; the rounded age result is saved. The form and sex parameter are not saved in localStorage, sessionStorage or IndexedDB, or used in analytics. This does not remove the existing necessary guest-session cookie or the storage of the chart on the server.
Email is optional. If you provide it and verify it through the link in the email, we'll send finished books (PDF) and links for signing in to your readings on other devices there. There are no mailing lists. When email is verified, the data-retention and guest-access period is set to 365 days. When you use the guest session, it is periodically extended for another 365 days from that request if fewer than 335 days remain; this is not exactly 12 months from every last visit. If the email has not yet been verified, the original 30-day period applies. When the period expires, access ends and the data is deleted during scheduled cleanup. Emails are sent through Resend (Ireland, EU); email addresses are not sent to AI. Deleting guest data also deletes the email address.
Backups are made daily, stored encrypted and deleted after about a month.
If you change time precision or sex in the form, you need to confirm consent again. The scope of old consents is not broadened. To change a parameter of an already saved chart, you must explicitly create a new reading: the finished result is not rewritten. Deleting guest data deletes all saved charts with the parameter and results, and the current guest's short readings and books. Files already downloaded stay with you.
