Effective date: January 17, 2026
This Privacy Policy explains how Let’s Zhuyin! (“the App”) handles information.
We do not ask for or collect personal information such as your name, email address, phone number, contacts, photos, or precise location.
We do not collect analytics or tracking data from the App (for example, we do not run advertising SDKs or behavioral analytics SDKs).
However, please note:
The App offers purchases/subscriptions through Apple In-App Purchase. Payments are processed by Apple, not by us.
When you make a purchase, we (and our purchase-management provider, RevenueCat) may receive or process information such as:
We do not receive your payment card details or billing information.
We use RevenueCat to help us manage and verify purchases/subscriptions and to provide features like restoring purchases.
We use RevenueCat with anonymous identifiers. This means we do not intentionally send RevenueCat information like your name, email address, or phone number.
To operate purchase/subscription services, RevenueCat may process purchase-related data (such as transaction/receipt validation information) and may also collect certain technical information (for example, device/app-related information) as required to provide their service.
RevenueCat acts as a service provider to us for purchase management. Their handling of data is governed by their own privacy policy.
Other than what is necessary for purchase/subscription processing described above:
We do not maintain a database of your personal information.
Purchase-related records may be retained by:
according to their respective retention policies.
We design the App so that it does not require collecting personal data. For purchase verification and subscription management, we rely on established providers (Apple and RevenueCat) that implement security measures appropriate to their services.
The App is not designed to collect personal information from anyone, including children. If you believe a child has provided personal information to us through the App, please contact us and we will address it. (In general, because we do not collect personal data, we typically have nothing to remove.)
If you use the App from outside your country, Apple and RevenueCat may process purchase-related information in accordance with their policies, which may involve transferring data to other regions.
We may update this Privacy Policy from time to time. If we make changes, we will update the “Effective date” above and post the updated policy where it is made available.
