Audio files and local processing
Mini Audio Converter plays, extracts and converts audio on your device. We do not upload your audio files to our servers, use them for advertising, or share their contents with advertisers. Files are accessed through your selections in the system file picker. If you choose a cloud document provider or share an exported file, that provider or recipient handles the file under its own terms.
The app stores temporary working copies, recent-file information and settings locally. Temporary audio caches are cleared during normal app startup and shutdown. Files you save outside the app remain until you delete them. You can remove app-local data using Android's app storage controls or by uninstalling the app.
Advertising and privacy choices
The app uses Google AdMob to display advertisements, including personalized advertisements where permitted and according to your choices. Google's advertising SDK may collect and process IP addresses, advertising and app-set identifiers, other device or account-related identifiers where applicable, approximate location inferred from an IP address, ad interactions, crash and diagnostic information and performance data to provide and personalize advertisements, measure advertising performance and prevent advertising fraud. Mini Audio Converter does not create an app account or ask you for a Google password.
Google and its advertising partners receive advertising data through their SDKs. We do not sell your audio files or provide their contents, your payment verification identifier or purchase tokens to advertisers. We do not use payment verification information to personalize advertisements.
Where required, Google's User Messaging Platform presents a privacy message before advertisements can be requested. You can revisit available choices using the app's "Ad privacy options" entry. Depending on your region and choices, advertisements may be personalized, limited or unavailable. Choosing not to consent does not upload your audio files or disable local playback and free conversion features.

In-app purchases and payment verification
Google Play processes in-app payments. We do not receive your card number, bank account credentials or Google password. To verify a purchase and prevent duplicate use or fraud, the app sends a payment-only device identifier, product identifier and purchase token, together with application, conversion operation and request information, to our payment verification service over HTTPS. Our verification service checks the purchase with Google Play and can receive an order reference, purchase status and purchase time as part of that verification. Google also sends authenticated purchase and cancellation notifications to the service.
The payment identifier is used only for payment verification, transaction association, recovery and fraud prevention. It is not used to track you across apps or for advertising. Purchase tokens and transaction records are used only to validate and complete purchases, prevent duplicate fulfillment, support recovery or refunds and meet applicable record-keeping requirements. Payment verification does not send your audio files, filenames or audio contents to our servers.
Retention, deletion and security
Audio working files and settings remain on your device as described above. A purchase recovery journal may be stored locally until the conversion is completed. Our payment service encrypts purchase tokens and stores a keyed hash of the payment-only device identifier. For completed and consumed purchases, or revoked purchases, the service removes the encrypted token, device association and order reference after 90 days. Unfulfilled conversion credits are retained for recovery. Minimal token-hash records and fulfillment status remain to prevent duplicate use. Advertising data is retained by Google and its partners under their policies and your available privacy choices.
Contact yunfeng2003@hotmail.com to ask about payment verification records or request their deletion. Records still needed to fulfill a purchase, prevent fraud, resolve a refund or satisfy a legal obligation may need to be retained. Do not send passwords, payment card details or audio files with a privacy request. There is no app account registration or app account to delete.
Network services use HTTPS. Access to payment verification data is limited to authorized payment support and verification functions. No method of transmission or storage can guarantee absolute security.
Request deletion of payment data
To request deletion of Mini Audio Converter payment verification records, email yunfeng2003@hotmail.com with the subject "Mini Audio Converter data deletion". Include the Google Play order reference if available, the conversion product and approximate purchase date so we can identify the transaction. We may ask for limited information to verify the request. Do not send Google passwords, card details, raw purchase tokens or audio files.
We remove payment information that is no longer needed for fulfillment, recovery, refunds or legal record keeping. Unfulfilled credits and records needed to resolve a transaction may need to be retained until that work is complete. Minimal token hashes and fulfillment status are kept to prevent duplicate use; encrypted tokens, payment device associations and order references for completed/consumed or revoked transactions are otherwise removed after 90 days. To delete app-local audio caches and settings, use Android's app storage controls. Google advertising data and your related deletion/privacy choices are handled through Google's policies, device advertising-ID controls and Google ad settings linked above.
Privacy webpage hosting
This privacy webpage and our payment verification service are hosted through Cloudflare. Ordinary connection information such as an IP address and request information may be processed to deliver and protect these services. The payment service uses a daily keyed hash of the connection address for request limits; raw purchase tokens and device identifiers are not written to application logs. Visiting this page does not upload audio files from the app. Cloudflare Privacy Policy: https://www.cloudflare.com/privacypolicy/
Children
This app is not designed specifically for children. We do not knowingly use children's information for personalized advertising. If you believe a child has provided information to us, contact the privacy email above.
Changes and contact

Audio files and local processing
Mini Audio Converter plays, inspects, extracts and converts audio on your device. The Windows app does not upload your audio files or reference samples to a developer server. Files are accessed through your selections in Windows file and folder pickers. If you select a cloud-backed location or open an external webpage, that provider handles the interaction under its own policy.
Microsoft Store purchases
Optional consumable purchases are handled by Microsoft Store. The app requests product availability, prices, purchase results and remaining consumable balances through Microsoft's Store services. Payment details and Microsoft account sign-in are handled by Microsoft, not entered into this app or sent to a developer payment server. Microsoft handles Store account, transaction, device and diagnostic information under its privacy statement: https://privacy.microsoft.com/privacystatement
Local storage and recovery
The app stores settings, working copies, decoded audio and prepared exports in its local app data. To recover an interrupted settlement, it may retain a product ID, Store product ID and fulfillment tracking ID locally. The app retries that same settlement request after an interruption. It does not store your payment card details or Microsoft account password. Prepared exports and recovery information can remain until the operation is completed or the app data is cleared.
Advertising and diagnostics
The Windows build does not include the Google AdMob Android advertising SDK. Windows and Microsoft Store may collect operating-system, Store and crash diagnostics according to your Windows settings and Microsoft's policies. This app does not add a developer-operated audio-upload or analytics service to the Windows conversion workflow.
Support and privacy requests
If you email support, we receive the information and files you choose to send. Share only what is needed to investigate the problem. For support or privacy questions, contact yunfeng2003@hotmail.com. Microsoft Store order records and Microsoft account data are managed by Microsoft; the developer cannot erase those records from your Microsoft account.
Retention and deletion
You can remove local app data using Windows app settings or by uninstalling the app. Audio files and exports that you save outside the app's private data remain in the locations you selected and can be deleted there. Clearing local app data can remove unfinished conversion recovery information. For Microsoft account data controls, use Microsoft's privacy tools: https://account.microsoft.com/privacy
Privacy webpage hosting
The public privacy webpage is hosted using Cloudflare. Visiting it sends normal web request information, such as your IP address and browser details, to the hosting provider.

Audio files and local processing
The app plays, inspects, extracts and converts audio on your device. The app does not upload your audio files or reference samples to a developer server. You choose files through Apple's file and media pickers. A cloud storage provider may download or synchronize files you select under its own policy. Audio imported from the Music library must be accessible and DRM-free.
App Store purchases
Optional consumable purchases are handled by Apple. The app obtains product information, localized prices, transaction identifiers and purchase verification results from StoreKit. Payment card details and Apple Account sign-in are handled by Apple, rather than entered into this app or sent to a developer payment server. StoreKit verifies signed transactions on your device. An unfinished conversion purchase can be reused after a cancelled or failed export. After successful saving, the app records the transaction identifier locally and finishes that transaction with Apple. Apple's policy: https://www.apple.com/legal/privacy/
Local storage and recovery
The app stores settings, working copies, decoded audio, prepared exports and transaction recovery identifiers in its app data on your device. It does not store your Apple Account password or payment card details. Prepared exports and unfinished conversion information may remain until completion or removal of the app's data. Files saved outside the app remain in the locations you selected.
Advertising and privacy choices
The iPhone and iPad app uses Google Mobile Ads and Google's User Messaging Platform. The Mac app does not include these advertising SDKs. Google and its advertising services may process IP addresses, device and app identifiers, ad impressions and interactions, product interaction, performance and diagnostic information to deliver and measure advertising, prevent fraud and improve their services. IP addresses may indicate a general location. The app requests nonpersonalized ads, disables Google's publisher first-party ID, does not request location access, disables the advertising SDK's automatic device-location collection, and does not request Apple's cross-app tracking permission.
On iPhone and iPad, the app checks Google's consent requirements at launch and requests ads only when the consent SDK permits them. Where required, you can reopen the consent form using Ad privacy options in Settings. Availability and wording depend on your region and the messages configured for the app. You may choose an App Store purchase instead of a rewarded ad for a paid conversion. Google policy: https://policies.google.com/privacy
Diagnostics
Apple and Unity may process operating-system, Store and crash diagnostics according to the applicable settings and their policies. The conversion workflow does not add a developer-operated audio-upload or analytics service. Unity policy: https://unity.com/legal/privacy-policy
Support and privacy requests
When you contact support, we receive the messages and files you choose to send. Share only what is needed to investigate the issue. For support or privacy questions, email yunfeng2003@hotmail.com. Apple manages App Store order records and Apple Account data; Google manages its advertising and consent records. The developer cannot erase records from those providers' accounts.
Retention and deletion
Remove app data through your device's app storage controls or by uninstalling the app; on Mac, you can also remove its local application data. Clearing app data removes local settings and may remove conversion recovery information. Delete exported audio in the locations where you saved it.
