PRIVACY & DATA
LuckyNum Privacy Notice
LuckyNum is an on-device app for playful daily inspiration and random choices. You can use daily lucky cards, a personal number, decision lists and number draws without registering, signing in, or providing a name or birthday.
This notice applies to the ad-free LuckyNum 2.0.0. Advertising practices in versions earlier than 2.0.0 are outside its scope.
Information kept on your device
The app creates a random local identifier so that daily cards stay consistent throughout the day. This identifier is not an advertising identifier and is not sent by the app to our servers.
Your personal number, daily cards, saved cards, decision lists, number-draw history and preferences are stored on your device. Daily content is generated using the local identifier and your device's local date. The app does not provide its own account system or cloud-sync service.
LuckyNum does not automatically upload these local records to the developer. iOS may handle app data according to your device-backup settings. You and the operating system manage device backup and restoration.
Advertising and tracking
LuckyNum 2.0.0 does not display ads, contain advertising SDKs, read the advertising identifier or use advertising tracking. The app does not contain a third-party behavioural analytics service or a service that automatically uploads usage records.
Location, Photos and sharing
Lucky direction is a playful illustration. The app does not request location permission, read your live location or device heading, or provide live navigation.
Share images are created on your device. Content is passed to another app or service only when you choose a share destination. The receiving service handles the content under its own policies.
If you choose to save an image from the iOS share sheet, iOS may request permission to add it to your photo library. LuckyNum does not scan or upload your photo library. You can manage relevant permissions in iOS Settings.
Contacting us and external links
If you email support, we receive your email address and the message, attachments or other information you choose to provide, so that we can communicate with you and handle your request. Please send only information relevant to your enquiry. You can contact the address below about information you previously supplied for support.
Rating links, links to other apps and email feedback open external apps or pages only when you choose them. Those services handle data under their own privacy notices.
Retention and deletion
You can remove saved cards, delete your decision lists or clear number-draw history within the app. Deleting the app and its data removes its local records on that device. The iOS option to offload an app while retaining its documents and data may not remove those records. Images saved to Photos, content already shared with others and records retained in device backups must be managed separately in those locations.

Support email: mlaohu.app@gmail.com
The current in-app Feedback & suggestions action opens the email app addressed to diamont1001@gmail.com with a copy to diamont1001@163.com, as configured in the app. The public support email above is also available; these are distinct contact channels.
Changes between versions
If a future version changes how information is handled, this notice will be updated for that version. Advertising practices in versions earlier than 2.0.0 are outside the scope of this notice for the ad-free version.
