DuoDock: Split Screen Launcher
Last updated: November 10, 2026
DuoDock: Split Screen Launcher ("DuoDock", "the App") is an Android application developed by Krepel Studio ("we", "us", "our"). Its Android package name is com.krepelstudio.duodock.
DuoDock helps you select two installed applications, save them as an app pair, and request that Android launch them in Split Screen on compatible devices. This Privacy Policy explains what information the App accesses, how it is used and stored, and what happens when you use Google Play purchases or contact us.
Installed applications. To display applications available for selection, DuoDock uses Android's app discovery mechanisms to access limited information about launchable installed apps, such as their display names, icons, package identifiers, and launchable components. This information is used to populate the app picker, validate saved pairs, and request the launch of apps you select. DuoDock does not need access to the private content of those apps, your messages, or your browsing history.
Your app pairs. When you create a pair, DuoDock processes the identities and order of the two selected apps, the pair's displayed name (including any name you enter), and information needed to save and launch that pair.
Preferences. DuoDock may store your language, appearance/theme, haptic feedback, onboarding preferences, and whether the one-time Free pair creation has already been used.
These data are used to provide the App's functions. DuoDock is designed to process the installed-app list and saved pairs on your device, rather than uploading them to Krepel Studio servers. DuoDock does not create a history of which third-party apps you open or monitor their screen content.
Saved pairs, selected app identifiers, names, and preferences are stored in the App's private local storage. They remain there until you edit or delete them, clear the App's data, or uninstall DuoDock, subject to Android's own data-management behavior.
The Free version allows one pair to be created. The fact that this creation was used is stored separately from the pair itself. Deleting the pair does not reset that Free limit; this local record remains while the App's data is retained.
DuoDock does not offer its own account system, cloud synchronization, or cloud storage for your app pairs. Any operating-system-level backup or device transfer is managed separately by Android and depends on the device and application configuration.
You can remove a saved pair inside DuoDock. You can delete the App's locally stored information by clearing its data in Android settings or uninstalling the App. These actions do not automatically delete purchase records held by Google Play or messages you have sent to our support address.
DuoDock offers an optional one-time Pro Lifetime purchase through Google Play Billing. Google Play processes payments and may handle information such as your Google account, transaction details, payment method, and device-related information under Google's own terms and privacy practices.
DuoDock receives or checks purchase status and the purchase identifiers or tokens needed to unlock, verify, acknowledge, and restore Pro access. We do not directly receive or store your full payment card number or card security code.
Krepel Studio may have access to limited transaction information made available by Google Play to developers, such as purchase status and order-related details, for purchase support and administration. Google's handling and retention of payment information are governed by Google's policies: https://policies.google.com/privacy
If you choose to add a saved pair shortcut to your home screen, DuoDock supplies the shortcut information needed by your device's launcher, such as a label, icon, and a reference to the saved pair. Shortcut availability and management depend on your launcher.
When you launch a pair, Android starts the third-party applications you selected. DuoDock does not control the privacy practices, permissions, or data processing of those applications. Please review their individual privacy policies where relevant.
DuoDock uses limited Android package visibility to find applications that can be launched. This is declared through scoped app queries; it is not a request for unrestricted access to every installed package.
For its described functions, DuoDock does not require Accessibility Service, Usage Access, Notification Access, the QUERY_ALL_PACKAGES permission, permission to draw over other apps, broad file or media access, location, camera, microphone, contacts, or SMS permissions.
Google Play Billing may require the standard billing integration and communication with Google Play services. Adding a home-screen shortcut may require confirmation from your launcher. DuoDock does not require you to grant screen-reading or accessibility permissions to use its planned core functionality.
DuoDock does not display third-party advertisements and is not designed to include Google AdMob or advertising-related tracking. We do not sell your installed-app inventory, saved pairs, or preferences, or share your installed-app inventory for advertising or analytics monetization.
We do not operate a backend that receives your saved pairs or installed-app list. Limited information may be handled by Google Play for purchases, by your launcher when you request a shortcut, or by your email service and ours if you choose to contact support, as described in this Policy.
Google Play may also make app reliability information, such as crash or performance diagnostics, available to developers through its services. Such information is used to investigate stability issues; DuoDock is not designed to include your saved pairs or installed-app inventory in diagnostic reports.
If you email us, we receive the information you choose to provide, which may include your email address, message, and any attachments. We use it to respond to your request and address support issues. We keep support correspondence only as long as reasonably necessary for these purposes or to meet applicable legal obligations. You may contact us to request access to or deletion of information you provided directly to us, subject to applicable law.
We use Android's app-private storage and platform protections for locally stored information and limit access to information needed for the App's functionality. Payment processing is performed through Google Play rather than by DuoDock directly. No method of storage or transmission is completely secure, but we aim to minimize the information handled by the App and avoid unnecessary transfer of device information.
DuoDock is a general-purpose utility and is not specifically directed at children. We do not knowingly request or collect children's personal information through the App. If you believe personal information has been sent to us in a support request by a child, please contact us.
You control which applications you choose for a pair and whether to create a home-screen shortcut. You can delete saved pairs, change preferences, clear the App's local data, or uninstall DuoDock. Pro purchases can be managed through Google Play.
Depending on applicable law, you may have rights to request access to, correction of, or deletion of personal information that we hold, such as support correspondence. Contact us using the address below. We cannot directly delete Google's payment records or data stored by unrelated third-party applications.
We may update this Privacy Policy when the App's functions, integrations, data practices, or legal requirements change. The revised version will be made available at the App's published Privacy Policy page, and the "Last updated" date will be changed.
