Privacy Policy

1. Accounts and information on your device

This app is provided by Twinkle AI Labs (the "Operator"). It can be used without creating an account or signing in, and it does not ask for your name or contact details. Information processed when you contact the Operator by email, and in connection with ads, purchases and ratings, is described in the sections below.

Your theme and language settings, the sort order of the app list, the folder you have chosen as the save location, and your ad removal purchase status are stored on your device. Deleting the app also deletes this information, and no separate backup is provided.

2. Information about installed apps

The app reads, on your device, the list of apps that have an icon on the home screen and, for each app, its name, icon, package name, version, size, install and update dates and times, install source, minimum and target Android versions, and requested permissions and whether they are allowed, and displays them on screen. This information is not sent to the Operator's servers or to third parties, and it is not stored separately.

The app does not use the permission to query all apps installed on the device (QUERY_ALL_PACKAGES).

3. Saving and sharing extracted files

When you choose to save, the app saves the selected app's installation files to the Downloads › APK Extractor folder on your device. If you choose a different folder under "Save location" in Settings, the app saves to that folder, and it requests that the folder selection screen show only storage on your device. If the folder you chose cannot be used, the app saves to the Downloads › APK Extractor folder. On devices running Android 9 or earlier, the app requests storage permission to write to the Downloads › APK Extractor folder, and you can still use other features such as sharing even if you do not allow the permission. You can revoke a permission you have allowed at any time from the app permissions menu in Android settings. When saving to a folder you chose yourself, the app does not request this permission, and the access granted to that folder is released when you set "Save location" in Settings back to the default location.

When you choose to share, the app creates a compressed file (zip) in its temporary storage and passes it to the app you choose. Once an hour has passed since it was created, the temporary file is deleted the next time you share. Files that have been passed on are handled according to the policies of the receiving app or service, and the Operator cannot know how they are handled.

Files you save or share are not sent to the Operator's servers.

4. Advertising and privacy choices

The app provides ads through Google AdMob. A banner ad at the bottom of the app list screen, a full-screen ad after you save or share a single app, and a rewarded ad before you save or share several apps at once, may be displayed. To provide ads, measure their performance and prevent fraud, Google may process device identifiers such as the advertising ID, approximate location inferred from your IP address, records of app launches and ad views and clicks, and error and performance diagnostics. The list of apps installed on your device and the files you extract are not included in ad requests. When ads are loaded in advance, network communication may occur even before an ad appears on screen.

In regions where consent is required, you can choose whether ad-related information is processed through Google's consent management tool. When "Ad privacy choices" appears in the app's Settings, you can review or change your choices there. In Android settings, you can reset or delete your advertising ID. However, even if you delete the advertising ID or opt out of personalized ads, some ad-related processing may continue.

Information about Google's retention, deletion and international processing of information is available in the Google Privacy Policy and Google's partner services information. Once an ad removal purchase is verified, the app no longer requests new ads. Even then, information Google has already processed is not automatically deleted.

5. Purchase information

"Remove ads" is offered as a one-time in-app purchase through Google Play and is not a subscription. The app processes Google Play purchase information to verify and restore purchases, and stores the purchase status on your device. Details of your payment method, such as card numbers, are not provided to the Operator. Purchase information verified by the app is not sent to the Operator's servers either.

6. Rating requests

After you save or share files, the app may request Google Play's in-app rating prompt. Google Play decides whether the prompt is actually shown, and any stars and reviews you leave are processed by Google Play. The Operator does not receive the content of your rating through the app. "Rate this app" in Settings opens the app's page on Google Play.

7. Other external communications

When you open the app or return to it, the app checks whether a new version is available using Google Play's in-app update feature.

When you open the Terms of Service or Privacy Policy screen, the app retrieves the latest document from polaris.twinklelabs.kr. The request contains the document type and language. GitHub, which hosts this address, may process information such as your IP address in the course of the connection.

The list of apps installed on your device and the files you extract are not included in these communications.

8. Retention, deletion and your rights

Internal app data is kept on your device for as long as it is needed to provide the features. Clearing the app's data in Android settings or uninstalling the app deletes the internal data, and the Operator cannot restore it. Saved files remain after the app is uninstalled, so you must delete them yourself in your device's Files app, and copies you have shared must be deleted directly in the app or service you passed them to.

If you contact the Operator by email, the Operator processes your email address and the content of your inquiry in order to reply. Please take care not to send files, passwords or payment information that are not needed for your inquiry. To request access to, correction, deletion or restriction of processing of your personal information, or to withdraw your consent, please contact twinkle.ai.labs@gmail.com. For on-device data the Operator does not hold or information managed by Google, the Operator explains how you can act through the relevant device or service.

Information received through inquiries is deleted without undue delay once the response and any follow-up are complete. However, where retention is required by law, it is kept for the period set by that law.

9. Children's personal information and contact

This app is not directed at children under 16. If you become aware that a child's personal information has been provided to the Operator, please contact twinkle.ai.labs@gmail.com. The app is operated by Twinkle AI Labs, a name used by an individual.

10. Notice of changes

If this document changes, the changes and their effective date are announced on Polaris and in the app's policy screens. Ordinary changes are announced at least 7 days before they take effect, and changes that are unfavorable to users or otherwise material at least 30 days before.
