Terms of use

By DailyAstro · Last updated 2026-09-08

This English page is a translation provided for convenience. If it differs in any way from the Chinese original at 使用條款, the Chinese text prevails.

1. What this service is

From the birth date you provide, DailyAstro applies published BaZi date-selection rules and the 宜／忌 (suitable / to be avoided) data of the traditional almanac to produce “lucky day” scores for various purposes and a compatibility score between two people. The method is published in full in the methodology. These are judgements within a cultural and divinatory tradition — they are not scientifically validated predictions.

2. Not professional advice of any kind

What this service provides is not, and must not be treated as, professional advice in finance, investment, tax, law, medicine, psychology or human resources.

• A high score does not mean you will make money; a low score does not mean you will lose it. No outcome is something this service can predict or guarantee.
• Do not use this service to decide whether to buy or sell stocks, cryptocurrency, futures or any other investment. For decisions involving money, consult a licensed adviser.
• Gambling carries risk. “Speculation” (博彩投機) is a traditional divinatory label, not a tip that you will win. Stay within your means, and seek help if you need it.

3. Compatibility and employment decisions

The compatibility feature is a cultural reference. It should not be the sole or primary reason to hire, refuse to hire, promote or dismiss anyone. Employment decisions must follow the law of your own jurisdiction — including its rules on anti-discrimination, fair employment and privacy — and that responsibility rests entirely with you. Before you enter a third party's birth date (a job applicant's, for instance), make sure you have a lawful basis for doing so.

4. Accuracy of the data

The sexagenary calendar and the almanac 宜／忌 data come from the open-source library lunar-javascript. Printed almanacs of different editions, and calendrical schools of different lineages, disagree with one another to begin with. This service also does not implement true solar time (longitude) correction, so for some birth places and birth times the day pillar can be off by a day. We do not warrant that any calculated result is free of error.

5. Your data and third-party services

Birth profiles stay on your device. Clerk handles login, Stripe handles payment, and membership, usage and AI replies have server records; see the privacy policy. AI explanations forward computed results to DeepSeek using the site key (Gemini is also supported as a fallback). Google Calendar and your own optional AI keys are separate connections; you are responsible for protecting those credentials and their provider charges.

Membership, credits and payment

Plans labelled test mode are sandbox drafts and do not charge real money. For a live subscription, the checkout page must state the price, currency, tax and billing interval. Each paid month grants the plan allowance, with a separate daily limit resetting at 00:00 UTC. A usable explanation costs one credit; reopening saved text is free. Unused credits do not roll over and have no cash value.

A request without a usable reply restores member credits and daily allowance; interrupted requests with unknown outcomes may be resolved at the next check. The provider may still have processed them. Canceling renewal preserves access until the paid period ends. Failed payment, immediate cancellation, refunds or disputes can pause AI access. Refund and data-deletion contact arrangements must be published before live billing; statutory rights remain unaffected.

6. Provided as is · disclaimer

The service is provided as is and as available. We cannot guarantee the accuracy of traditional-culture interpretations or uninterrupted service. Date scoring is free; AI membership is billed at the price and interval shown at checkout. Any limitation of liability applies only where permitted by law and does not remove non-excludable consumer rights.

7. Acceptable use

• Do not repackage this service's results as professional advice or as guaranteed returns, and resell or distribute them to third parties.
• Do not scrape it in bulk by automated means or place an unreasonable load on it.
• Do not use it to harass, discriminate against or harm anyone.

8. Updates to these terms

If these terms change, the date at the top of this page will be updated. Continuing to use the service means you accept the updated terms.

If the law where you are does not permit some of the disclaimers above, that part applies to the minimum extent the law allows, and the remaining terms stay in force.
