ExtractoKit Privacy Policy
1. Scope
This policy covers ExtractoKit (提取宝) for iPhone and iPad. The information processed depends on the features you use and the permissions you grant.
2. Account, credits and purchases
The app uses an app-scoped iCloud identity to establish a service account. We process account and installation identifiers, session credentials, app version and language, credit balances and usage records, invitation codes and redemption records, membership status, and purchase verification data to provide these features, synchronize entitlements and prevent duplicate rewards or fraud. Apple processes App Store payments; we do not receive your payment card details or Apple Account password. App account records are also stored using Apple CloudKit.
3. Media and links
Local media tools access files you select and the permissions required for the selected tool. Locally processed media and extraction history remain on your device. Link processing connects to the source website and, where needed, our processing service; the submitted link and information needed for the request are transmitted. Websites and download hosts may receive your IP address and request information under their own policies. Our service stores diagnostic logs for server-assisted link requests and failure reports, including the submitted URL, IP address, request time, app version and error information. These logs remain after the request finishes to help troubleshoot failures and maintain the service. The original pasted sharing text is removed before these logs are stored; the submitted URL is retained. These service logs are separate from the extraction history stored on your device. Do not submit confidential links or content you are not authorized to use.
For some server-assisted link requests, our service retrieves and processes the linked video and temporarily caches a video file to provide a playable or downloadable result. Temporary download links expire after 10 minutes. Expired files are removed during subsequent media processing or access; link expiration does not mean immediate file deletion. Related request logs are retained as described in this section.
4. Notifications
If you enable notifications, our push service stores the Apple push token, a random installation identifier, app version, system language and registration timestamps to register, deliver and maintain notifications. This registration does not require your contacts or media files. You can disable notifications in iOS Settings.
5. Analytics and advertising
We use Umeng analytics for app usage events, feature interactions, purchase outcomes and technical diagnostics. We use Google AdMob and its consent tools for ads and advertising measurement. These services may process device or app identifiers, IP addresses (including approximate location derived from IP), usage and advertising interactions, crash information and performance data. Their practices are described in the linked policies below. After the in-app privacy notice is accepted, the app may initialize analytics and advertising services. App Tracking Transparency permission controls access to the advertising identifier and tracking permission; refusing it does not disable all analytics or all ads. Advertising choices may also be available through the consent interface where applicable.
6. Service providers and security
Apple provides iCloud/CloudKit and App Store purchase services. Our hosted backend processes account, reward, verification and notification requests. Google and Umeng process data for the purposes described above. We restrict service access and use encrypted connections where supported. Information may be processed in the regions where these providers operate. Contact support for questions about your data or these providers.
7. Deletion and retention
In the updated 1.0.6 release, use My → More Settings → Delete Account and confirm. The app deletes active account, balance, reward, invitation and cloud account records, clears local account credentials, and removes the current installation’s verified push registrations. An interrupted deletion can be resumed with the same iCloud account. Local media files remain on your device. Deleting the app alone is not an account deletion request, and deleting your app account does not cancel Apple subscriptions.
8. Limited records after deletion
We retain minimal pseudonymous deletion and anti-abuse records to prevent account data from being silently recreated and prevent repeated reward claims. Minimal transaction identifiers and verification records may remain for transaction integrity, refunds and fraud prevention, without the active account profile. Completed deletion receipts are valid for 30 days for safe retries and are purged during subsequent deletion maintenance; incomplete requests remain available to finish cleanup. Operational backups and security logs may retain earlier records until replaced or removed; they are not used to reactivate deleted accounts. Contact support for access, correction, deletion or retention questions, including records held by service providers.
9. Your choices and support
You can manage app permissions, notifications and tracking in iOS Settings. Manage or cancel Apple subscriptions in App Store subscription settings. For help accessing, correcting or deleting your data, email yanjiawen1992@gmail.com. We may ask for information necessary to verify that a request concerns your account. Do not send your Apple Account password or payment card details.
