Legal
Terms of Use
Last updated: October 29, 2026. These terms cover the iYinYang calendar on iPhone and Android, iYinYang for iPad, and the website at iyinyang.com.
The apps
iYinYang on iPhone is the 60-year Animal and Element calendar. You look up a day and open that date’s reading. iYinYang for iPad is a separate portrait desk. Element, Animal, and Elemental Animal stay on one screen, and you can save as many profiles as you add. Each app keeps its profiles on the device. There is no account.
What a reading is
A reading is for reflection and for a Chinese calendar tradition. It is not medical, mental-health, legal, or financial advice, and it is not a prediction you should rely on for those decisions.
Purchases
On the App Store, Apple handles the purchase. On Google Play, iYinYang can start free, and Pro is an optional one-time unlock handled by Google. It is not a subscription. This website does not sell either app and does not receive your card number. Refunds, restores, and billing questions go to the store that sold the app.
The website
iyinyang.com describes the apps and holds this page and the Privacy Policy. It has no account and no contact form. Support is by email.
Other apps
If an older listing still sends you here for a different app, name that app when you write. Those links move with the next update.
Changes
If these terms change, the date at the top of this page will change.
