Frequently asked questions
How do I get started?
On the first screen, tap "Read my Four Pillars", then enter a name (a nickname is fine), gender, your date of birth in the Gregorian calendar and your birth time, and tap "Build my chart". Once your chart is ready, check your daily fortune on the Today tab.
Do I need an account or an internet connection? Where is my information stored?
No account is needed. What you enter is saved only on your phone and is never sent to us or any server, and your chart is calculated on your phone, too. On Android, watching an ad to open today's fortune or a talisman needs an internet connection.
I don't know my birth time.
On the birth time screen, choose "I don't know my birth time". You get a six-character reading from your year, month and day pillars without the hour pillar. If you find out the time later, add it in Settings > Edit my info.
How do I change my birth date or name?
Tap the gear icon (Settings) at the top of the screen > Edit my info. Your chart and fortune are recalculated after the change.
Can I enter a lunar calendar birthday?
Dates of birth are entered in the Gregorian (solar) calendar. If you only know your lunar birthday, convert it to the Gregorian date first. Enter your birth time as the local time where you were born.
How do talismans work?
On the Talisman tab, choose a talisman and open it for the day (on Android, by watching a short ad once a day for each talisman), then press and hold to charge it; it then boosts that day's fortune. Talismans are just for fun inside the App and cannot be bought or sold for money.
Are the readings accurate?
Haru Saju readings are entertainment based on traditional Four Pillars theory; they do not predict or guarantee the future. Please make important decisions, such as about health, money or relationships, with your own judgment and, where needed, with a qualified professional.
Does the App send notifications?
No. The App does not send notifications. Open the App and check the Today tab for the day's fortune.
How do I change the language?
Go to Settings > Language and choose from 20 languages, or choose "Use device language" to follow your device.
How do I delete my data?
Go to Settings > Start over > Erase to delete your profile, chart and talismans. Uninstalling the App also removes its data from the device. Because we never receive the information you enter, there is nothing to delete on our side. Advertising data processed by Google is managed in your device settings and Google's privacy controls. Usage statistics and crash reports already sent to Google Firebase are deleted automatically after their retention period (2 months for event-level analytics data, about 90 days for crash reports).
Are there in-app purchases or ads?
There are no subscriptions. On Android, you can make an optional one-time “Remove ads” purchase through Google Play, which turns off the ads described here; iOS has no in-app purchases. On Android, you watch a short rewarded ad once a day to open today's fortune and each talisman. If an ad does not load, check your internet connection and try again a little later. Questions about store purchases and refunds are handled by the App Store or Google Play.
Haru Saju readings are for entertainment, based on traditional Four Pillars (Saju) theory, and do not predict the future. Please make important decisions with your own judgment.
