2. Frequently Asked Questions
The app will not open or keeps crashing. What should I do?
Please update to the latest version, restart your device, and confirm that your system version meets the app requirements. If the issue continues, email us your device model, system version, app version, and reproduction steps.
Why are some features unavailable?
Some features may require system permissions, network access, subscription entitlement, enough storage space, or third-party service availability. Please check permission settings, network status, and any message shown inside the app.
How do I manage camera, microphone, photos, or notification permissions?
Open your device system settings, find the app, and enable or disable the required permissions. If you disable a permission, features that depend on it may stop working.
Where is my data stored?
It depends on the specific app. Some data may be stored locally on your device, some content may be exported by you to Photos, Files, or other apps, and some features may send necessary data to servers or third-party services for online processing or sync.
How do I delete my data?
You can delete content inside the app, or uninstall the app to remove local app data. Content saved to your photo library, files, or other apps must be deleted from those locations separately.
My purchase or subscription did not activate. What should I do?
Make sure you are signed in with the same app store account used for the purchase, then try restoring purchases. If it still does not work, send us the platform, purchase time, and screenshots. Do not send full credit card numbers or other sensitive payment information.
How do I request a refund?
Please request refunds through the App Store, Google Play, or the applicable payment platform. Refund rules and decisions are handled by the relevant platform.
