Privacy Policy

1. Information we collect

The App has no sign-up or login. Your name, gender, date and time of birth and readings stay on your device and are never sent to our servers, to Google or to anyone else.

The Android and iOS store versions of the App include Google Firebase Analytics, Firebase Crashlytics and Firebase Remote Config, which send usage statistics, crash reports and update-check data to Google as described in section 6. The App does not track your location. On Android, the App includes the Google Mobile Ads SDK (Google AdMob) to show rewarded ads, and Google processes advertising data as described in section 6.

2. Information stored only on your device

The following information, which you enter or which is created as you use the App, is saved only in the App's private storage on your device. We cannot access it.

• Your profile - name or nickname, gender, date of birth (Gregorian calendar) and birth time (or that the time is unknown)
• Activity - the day you opened today's fortune, the talismans you opened today, and the talisman you charged and the day you charged it
• Settings - app language and whether sound effects are on

Your chart, today's fortune, the fortune calendar and other readings are calculated on the device from this information whenever needed and never leave it. The App does not add its own passcode or encryption; your data is protected by your device's own security, such as the screen lock. Deleting the App deletes this data from the device. Copies in operating-system device backups may remain separately (see section 5).

3. How your birth information is used

Your date and time of birth are used only to build your Four Pillars chart (year, month, day and hour pillars) and to calculate your daily fortune. Your name and gender are used to address you on screen and in readings such as the Ten Gods. You may use a nickname instead of your real name.

To place solar-term boundaries and apply the true solar time correction, the App reads the standard time zone set on your device when you enter your details. The App does not use your location. If you enter someone else's details, please make sure they agree.

4. Device permissions

The App does not request any device permissions. It does not ask for access to your location, contacts, photos, camera, microphone, calendar or notifications. On Android, the App declares internet access and the advertising ID permission so that the ad SDK can load ads; these do not show a permission prompt. For advertising identifiers, see section 6. On Android and iOS, Firebase also uses the internet connection to send the data described in section 6; this does not show a permission prompt either.

The App plays sound effects bundled with it and uses vibration feedback. You can turn sound effects off in Settings (the gear icon) > Sound effects.

5. Device backups

The App has no backup, export or sync feature of its own. Depending on your device settings, your operating system's backup (such as iCloud Backup on iPhone or Google's Android backup) may include the App's data. Those backups are handled by Apple or Google under their own policies (https://www.apple.com/legal/privacy/ and https://policies.google.com/privacy), not by us.

6. Advertising, third parties and app stores

On Android, the App uses Google AdMob to show rewarded ads. An ad is requested only when you tap the button to watch one to open today's fortune or a talisman. When an ad loads, the Google Mobile Ads SDK connects to the internet and, depending on your device settings and applicable consent, Google may collect and process your IP address (including approximate location), the advertising ID and other device identifiers, app and ad interactions, and diagnostic data for advertising, measurement, analytics and fraud prevention. These data are encrypted in transit.

Your name, gender, date and time of birth and readings are never passed to the ad SDK. Google and its partners process advertising data under their own policies, possibly on servers outside your country (https://policies.google.com/privacy and https://policies.google.com/technologies/ads). You can reset or delete your advertising ID, or opt out of personalized ads, in your Android device settings.

The Android and iOS versions of the App distributed through the app stores include the Google Firebase SDKs (firebase_core, firebase_analytics, firebase_crashlytics and firebase_remote_config). Firebase Analytics automatically records usage events such as app opens, screen views, session length and first launch, together with the app version, device model, OS version, language and country settings, an app instance ID and an approximate location estimated from your IP address (not GPS). On Android, it may also read the advertising ID where your device settings allow. We use this to understand how the App is used and to improve it. On Android, Firebase Analytics may also automatically record in-app purchase events (product ID, price and currency). Firebase Crashlytics sends a report when the App crashes or hits an error (stack trace, app version, device model, OS version, free memory and storage, screen orientation, a Crashlytics installation ID and the time of the crash), which we use only to find and fix bugs. Firebase Remote Config downloads a small setting when the App starts or returns to the foreground to check whether an update is required; for this it sends the Firebase installation ID, the app ID and version, the platform and your language and country settings.

What you enter in the App and the results it shows are never sent to Firebase. Firebase data is encrypted in transit (TLS) and processed by Google as our service provider; we see only aggregated statistics and crash reports that do not identify you by name or email address. Event-level Analytics data is kept for 2 months (aggregated reports may be kept longer) and crash reports for about 90 days. Development builds do not send data, and if Firebase cannot start, the App keeps working without sending anything. There is no in-app setting to turn this off; uninstalling the App stops further collection. For how Google handles Firebase data, see (https://firebase.google.com/support/privacy).

We do not sell the information you enter or provide or share it with third parties. Apart from the Google Mobile Ads SDK and the Firebase SDKs described above, the components the App uses work only on your device and do not send data.

On Android, the App offers one optional one-time in-app product, “Remove ads” (product ID remove_ads), sold through Google Play; there are no subscriptions, and iOS has no in-app purchases. Payment is handled entirely by Google Play Billing, and we never receive your card or payment details. The App keeps only the purchase state on your device and re-checks it with Google Play’s purchase records when the App starts, so refunds are reflected; we have no server that stores purchases. Refunds and cancellations follow Google Play’s policies.

The App is distributed through the Apple App Store and Google Play. Downloads, payments and reviews are handled by those stores under their own privacy policies. The stores may give us aggregated statistics, such as download counts, and, depending on your device settings, crash reports that do not include the information you entered.

7. Children's privacy

The App does not ask anyone, including children, to create an account or give contact details, and what is entered in the App stays on the device. The Firebase usage statistics and crash reports described in section 6 are collected in the same way for every user, and ads in the Android app are provided by Google AdMob as described in section 6. If a child has sent us a support email, a parent or guardian can contact us to have it deleted.

8. Retention and deletion

Your information stays on your device until you erase it. You can change your name, gender, date of birth and birth time at any time in Settings (the gear icon) > Edit my info.

To erase everything at once, go to Settings > Start over > Erase. This deletes your profile, chart, talismans and activity (only a language you chose yourself is kept). Uninstalling the App also removes its data from the device; copies in device backups must be deleted from the backup service.

Erasing data or uninstalling the App does not delete advertising data already processed by Google. Manage it with your device's advertising ID settings and Google's privacy controls; we cannot erase data held by Google.

Erasing data in the App or uninstalling it does not delete usage statistics and crash reports already sent to Firebase; they are deleted automatically after the retention periods described in this policy. Uninstalling the App stops any further collection.

9. Your rights and contact

Because the information you enter never leaves your device, you can view, edit and delete it directly in the App at any time. For questions about this policy, or to ask us to access or delete support emails you have sent us, please contact us below.

Firebase usage statistics and crash reports are not linked to your name or email address, so we generally cannot pick out the records that relate to you. You can stop further collection by uninstalling the App, and you can contact us below with any questions about this data.

10. Support emails

If you email us, we receive your email address, the content of your message and anything you attach. We use this only to answer you and resolve the issue, and keep it only as long as needed to handle your inquiry and comply with applicable law. Please do not send payment card details or passwords, and there is no need to include your date of birth or other personal details we do not need.

11. Changes to this policy

We may update this policy when the law or the App's features change. Updates will be posted on this page with a new effective date.
